·       Computers in Geology newsletter & web site (1992 to present). I began working with the CSIRO as a student on the prototype Mutooroo solution mine, and encountered careful measurement and data sharing across disciplines. Interested by this, I have published articles about computing from a field geologist’s perspective, encouraging measurement and cross-discipline data integration.

·       Geophysical log and tape management (1984-85, 1993-99, 2002-04). Work with Century Geophysical showed me the value of a earth model based on geophysical borehole logs. At Santos Limited, I integrated geophysical, laboratory and rig side observations into a database with exports to all computer software. I then showed how to use the chemistry, quality, and geophysics models on the amalgamated data.

·       field oriented hydro/structural/enviro data collection (1986–88, 1991, 1996, 2000-02). I developed computer systems to monitor groundwater and slope stability for the Electricity Trust of South Australia. I self-funded and developed a prototype, FELDBUCH, and published the ELASTIC data model. At the University of Melbourne I expanded into Landcare issues by using satellite imagery.

Though I have been employed by several companies my work has revolved around a few major themes:

down hole geophysical log library

I have worked on integrated geophysical log library, tapes catalogue and loading utilities in 1984-1985, 1993-1999, and 2002-2004. With Century Geophysical I was involved in engineering investigations in three countries including the Jabiru Oil Field Offshore Storage Facility (Timor Sea), OK Tedi tailings dam (Papua New Guinea), the Sweetwater Mercury Outboard plant (Oklahoma), the Leigh Creek Coalfield (South Australia), the Lochiel Trial Pit (South Australia) and the Oaklands Joint Venture (New South Wales). This work showed me the potential for geophysical borehole logs to be used to generate a model of the earth that could be used by all disciplines. The work at Santos Limited, integrated data from geophysical, laboratory and rig side observations into an earth-model database with export utilities to all computer software used on site. This was supported with tip sheets on how to use the software to model geological properties from the amalgamated data. Models included oil maturation, reservoir quality, and seismic velocity. I refurbished this system in 2002-2004 to take advantage of improved software.

field data collection systems

I have worked on hydrological, structural, and environmental field data collection systems in the periods: 1986-1988, 1991, 1996, and 2000-2002. Inspired by the truck-mounted systems at Century Geophysical I developed from scratch, computer systems and procedures to monitor groundwater and ground movement measurements for the Electricity Trust of South Australia. This included integrated data logger software, time series plots and exports to Vulcan software. I self -funded my research into field data collection and published the ELASTIC data model. The research at the University of Melbourne gave me an opportunity to examine this problem from the Landcare perspective and include remote sensing.

Integrated mining studies

The work for the Electricity Trust of South Australia and Western Mining Corporation (1986-1991) involved drill rig supervision, instrumentation and pit/drive mapping for quality/reserves, geotechnical and hydro-geological objectives at the Lochiel Trial Pit (SA), Leigh Creek Coalfield (SA), Long (WA), Victory (WA) and Lanfranchi (WA) mines. I have undertaken geological mapping underground at the Lanfranchi (including Schmidts decline) and other mines near Kambalda, as well as surface mapping for the Mariners portal/decline (Widgiemooltha), the Leigh Creek Coalfield, and the Lochiel Trial Pit (Northern St Vincent Basin). From this work I designed and applied ground support programmes using software including: ground water modelling with Dames and Moore TARGET, and cable bolt pattern design with the CSIRO structural and reinforcement application toolkit (SARAT)

I have managed geotechnical drilling programmes for the raise bore for the Schmitts decline (oriented diamond drilling), Leigh Creek Coalfield (rotary triple tube) and the Lochiel Trial Pit (reverse circulation, rotary and oriented core). Associated with this drilling I installed, calibrated and monitored instrumentation including piesometers, extensometers, and stress gauges. I also wrote my own analysis systems with data logging programmes in Basic and storing, processing and plotting the data in spreadsheets (Lotus 123 and Microsoft Excel).

2001 - 2002          researcher, The University of Melbourne

The principal reason in becoming a consultant was to allow me to publish on developments of mineral surveying practice and influencing the education of field geologists. This culminated in being admitted to the University of Melbourne to undertake a research degree. This research was funded under a SPIRT grant via the Australian Postgraduate Award (Industry) at the University of Melbourne.

·       Candidate for Master of Applied Science by research with the Department of Geomatics, Faculty of Engineering, with the thesis title: Remote temporal monitoring of land use.

·       Component of the Strategic Partnerships with Industry – Research and Training (SPIRT) grant titled “Multi-temporal inventory of land use and land cover: an investigation of the use of high resolution satellite imagery and integration with non-image data”.

In essence thesis is about the integration of field data from multiple sources. While the degree, as a research degree, is not a professional engineering degree, the geomatics department in the Faculty of Engineering, is accredited by the Institution of Engineers with an undergraduate four year engineering degree.

1996- 2000           Computer Geologist, Affinity Contracting & Search

My move to Affinity Contracting and Search was made because I needed to work with a team. Towards the end of the 1990s it became apparent that I could no longer compete technically as an individual contractor against the multi-disciplinary teams being provided by the international service companies like Schlumberger Geoquest and Landmark Graphics. I had to find a partner to provide the special services for the more general PC and network support while I concentrated on the data, processing and database aspects of the work for mining companies. I found a company Applied micro Systems, later Affinity IT Recruitment, that was run by a surveyor, Chris Hall, who shared the same vision of geo-computing. By 1999 I was working with a team of five geo-computing specialists and a full time manager. However, I had traded technical issues for human issues.

My action plan to build the business was three-fold. I had to convince the manager to persist with the vision, encourage the other technical team members to combine their talent and then emphasise our benefits to the client who was used to dealing with a single face. I followed the same plan in each case. I made a point of volunteering to do induction duty. I found an opportunity to explain my hopes to each newcomer then at a later time when they showed anger and frustration I asked and listened to their ambition. I made a point of trying to find something, even a just a token, that would show that I took their concerns seriously and was trying to progress that. No particular situation stood out there was just countless conversations over coffee, in the corridor and toilet. Over time inertia built up and we were achieving each other’s goals. Once all parties were seeing success it was much easier to maintain the sense of working together.

The senior UNIX administrator said he was very happy with our manager, Cheryl Smith, because she paid his invoice on time and always went out of her way to help him. This was an experienced surveyor who had his own company and had spent the previous two or three years contracting through another company. To impress him we must have been working for each other not just for ourselves and this indicated to me that we had built a team.

Then when our contract at Santos was closing in 2000, another team member, who had been very cynical about working in the mining industry, walked up to our supervisor, and said anytime that he needed help he would be more than happy to work for him. They had clashed on a number times and I had worked hard for each to see the strengths of the other. Finally, our most junior member came up to me after our last drinks and thanked me for supporting him over the two or more years. I was touched and I had to explain that it went with the job and he shouldn’t think it so special.

As for the technical side of the work I had:

·       General consulting responsibilities:

à      geological and exploration computing

1996- present       Proprietor, "Computers in Geology"

When I began working with the CSIRO as a vacation student on the prototype Mutooroo solution mine, I took for granted the careful measurement and data sharing across disciplines. Later with Century Geophysical I saw that this was not prevalent across industry. When I got a chance I published computing from a field geologist’s perspective, with the emphasis on measurement and cross-discipline data integration, picking on topics shunned by academics. These received support and encouragement from other industry geologists for the practical solutions and frank opinions. Some of the on-going benefits from this work are:

·       Research, design and prototyping of an electronic field notebook for the earth sciences.

·       Analysis and design of the ELASTIC data model.

·       http://users/

1991 - 1996          Contract computer geologist.

 I had major contracts with the Electricity Trust of South Australia (1991) and Santos Limited (1992-1996). I was responsible for review, design, evaluation, and integration of geo-scientific computing systems.  Highlights were

·       The design and construction of a  turnkey hydrological/structural data collection system for ETSA (1991),

·       Hydrogeological modelling of the Leigh Creek Coalfield with Target (1991)

·       System support for MINCOM Geolog, Beicip-Franlab Matoil, and InDepth MIRA for  Santos Limited (1992 to 1996).

·       The management and purchase of plotting consumables for Santos Limited (1994 to 1996).

·       Manage the Novell Netware 4.1 roll out at Santos Ltd (October 1996 to February 1997).

·       Study tour of the SCADA and telemetry systems of the LaTrobe Coalfield in Latrobe Valley, Victoria (1991).

·       Business mapping of the Computer Users Group, Santos Ltd (October 1996).

·       The design and management of a geophysical wireline logs database for Santos Limited (1993 to 1996)

I first came across Remote Telemetry Units, associated with portable weather stations, in Queensland in 1984. I then hoped to use them with mine monitoring in ETSA and was the first author of a strategic plan and technical specification for the Leigh Creek Coalfield but my contract expired before I saw the SCADA system implemented. With Santos I touched on PRIM as an observer in the preliminary PRS design meetings and oversaw the move of the office SCADA PC to the new Santos building. Though Leigh Creek is a coal mine, the dewatering and pump control is the most significant aspect. In this regard the topology is the same as the Santos production system, but whereas Leigh Creek’s system was at the base level, the SCADA vendors consider the Santos system as the most sophisticated.

The work for the Electricity trust of South Australia was based on a sound knowledge of groundwater modelling theory and practice. The Leigh Creek Coalfield required constant dewatering to remain active. The pumping schedule was determined from a finite difference model in the Dames & Moore proprietary software Target. In 1991 I manipulated the cells in the finite difference model and then ran the model for several scenarios. The results from the runs were used in the review report of the dewatering programme. working at the Leigh Creek Coalfield I was very much a cog in the machine, with strict procedures for relating to every other department and the other specialists in the Planning Department. Primarily, my work was summarised in the principal consultants’ reports.

The work I have done on mines always included a strong component of geotechnical work and so I was continually involved in identifying and controlling safety issues. However, it was an office exercise of which I am most proud. At Santos I was asked to manage the purchase of cartographic consumables. Within two years I identified that office staff had not been following fire brigade requirements for inflammable inks, substituted alternative printers, resolved an ongoing manual handling hazard and cut expenditure to a third. At the same time I improved the quality of maps by trying different papers and matching printer to screen palettes. It was good engineering with accounting, and environmental success. The responsibility for the purchasing was handed over seamlessly to the supply department at the completion of the project.

Applying innovation as a contractor it is critical that we can adapt to change and have our own performance reviewed. While I was a contractor with Santos Limited I was assigned to the exploration computer users group that was responsible for introducing new technology into petroleum exploration and development teams. Just after I had started, Santos introduced formalised performance reviews, which coincided with the federal government requirement for compulsory training.

On rough paper I listed my own career development priorities, the problem areas of the work for the current year as I had identified in monthly reports and potential future technological improvements I had gleaned from reading journals. These, I synthesised into short, medium and long term development plans for the training scheme requirements at the end of the form. Then it was simple matter of allocating the reasoning to the former sections. Each year I built on the previous years form, establishing a development narrative.

The Chief Operations Geologist brought my positive approach to change management to the attention of the Technical Services Manager and I was seconded as department coordinator at the time of documenting the department’s procedures for the ISO9001 quality system.

It was also during this time that I recognised that liaising with clients in a courteous, responsive and timely manner gave me a clear advantage. At Santos Limited, the roll-out of the PC and Novell computing system to replace the first generation Wang word processing system with a PC and Novell network was outsourced to Applied Micro Systems. Unfortunately, the internal management information systems department, had over time, soured their relationships with their customer departments. I was independent, and because of my systems analysis work for the exploration technical services department, had a broad understanding of the dependence of the many computing systems at Santos.

I examined the personnel charts to identify general managers for all parts of the corporation. I then prepared a form letter signed by the manager of exploration technical services explaining the company wide change, stating my authority to manage that change and asking that they inform their managers. This was then followed by a series of meetings.

I would book a formal appointment with a manager. At the meeting I would give a fifteen minute explanation of the work and then answer any questions. At the end of the meeting I would ask him to appoint coordinators who could represent each of the types of systems within the department.

I would then meet with each of the coordinators and explain that I was a geologist who had been seconded to the project because I had been working on the systems analysis of the company as a whole, but that I knew nothing about the details of their work. Together, we would then prepare action plans for their representative system and modify their department on the timeline chart representing the whole of the company. I would take these action plans to the contractor would then adapt the system within the bounds allowed by the management information systems department.

Then again together we would explain the change to the whole department in a formal lecture, show the timeline chart and introduce the contractors who would be doing the work. This allowed individuals to reassure themselves that we had overcome any migration, confidentiality and department interdependence issues with their own files.

On the actual days of the changeover, the coordinators would collect notes on any problems, which were then addressed at a final coordinators meeting with the contractors present. Once the corrections had been completed I would again ask for an appointment with the manager and check that he and she were also satisfied.

I had initially declined renewing my individual contract with Santos Limited as I wanted to pursue more consulting activities. However, at Santos, the roll out of the next business unit after I had left, though planned and left in good order, had gone astray through misunderstandings on the weekend of the implementation. Santos rang me and asked that I come back as a consultant and promised a carte blanche contract with which I was able to negotiate with several larger consulting firms and eventually settled with Applied Micro Systems and which led to the formation of Affinity Contracting and Search.

1990       Geotechnical Geologist, Western Mining Corporation.

I was responsible for all geotechnical investigation in approximately 10 mines (underground and open cut) of the Kambalda Nickel Operations. The work utilised my experience and understanding of the principles of hydrogeology.

Lanfranchi is an underground nickel mine 100km south of Kambalda. A further ore deposit, Schmitts, a kilometre or so from the main deposit was being accessed by an underground decline. A raise bore was being planned to allow for an exhaust for the new lobe. However the raise on the main deposit, also an exhaust, leaked salty water that was driven by the surface fans into an aerosol, which inhibited several acres of sandalwood scrub.

I redrew the mine sections into, full surface to below maximum mine depth, geological cross-sections. I did this to establish any formations that could be acting as aquifers but more importantly to show the extension of faults which were seen in the mine to be leaking and were suspected of being recharged by surface rainfall. I sited two angled geotechnical holes that would intersect a body of rock that was intact to confirm the position of the raise.

The first hole intersected faults, making water, as did the second. A self-draining lining was designed for the raise where it intersected the fault, so as to prevent the build up of head, which had cracked the concrete in the first raise. The exploration geologists used the fault information and redrawn plans to develop further ore targets.

As geotechnical geologist at Kambalda Nickel Operation my primary responsibility was to use mine design to stop people getting seriously injured and minimise the environmental damage. My principal disappointment was that I alone was shouldering the practical burden of improving OHSW and environmental management The responsible officers were working at policy and statutory monitoring without feeding back into the work place procedures, but to be fair to Western Mining I had massive support from the mine managers and foremen.

In contrast, the Leigh Creek Coalfield where the Five Star programme developed in South African mines, was used, I felt that the burden of improvement was more equally shared between the policy, management and operational levels.

1990       Lecturer - mathematics / demonstrator - computer studies,

WA College of Advanced Education / Kalgoorlie College, Kalgoorlie.

1989 - 1990          Sample preparation, Genalysis Laboratories Pty Ltd,

Soil and rock sample preparation at the Kalgoorlie laboratory.

1986 - 1988          Geologist, The Electricity Trust of South Australia.

Probably my most significant achievement in this period was the design and construction of a hydrological/structural data collection system for the Electricity Trust of South Australia (1996 –1998, 1991). I developed from scratch, computer systems and procedures to monitor groundwater and ground movement measurements. Initially implemented for the Lochiel Trial Pit the system was then transferred to the Leigh Creek Coalfield. Included integrated data logger software, time series plots and exports to Vulcan software. It was extremely robust and ETSA Marketing used the system as a prototype for an electricity meter reading system. I continued my research into field data collection and later influenced design across Australia through my newsletter Computers in Geology.

GEOLOGIST - Production Planning Branch

(supervisor: Engineering Geologist, Leigh Creek)

September 1998 to February 1989

My duties at the Leigh Creek Coalfield were an extension of my work at Lochiel. They included:

·       Installation of the computerised piezometric data collection system designed by Coal Resources.

·       Providing advice with regard to instrumentation.

·       Implementing the structural investigation procedures designed by Dames and Moore geotechnical consultants.  This involved pit mapping, setting up a structural database and quality control procedures.

·       Supervising geotechnical, hydro-geological and environmental instrumentation, sampling and field studies at the M10 Highwall Trial.

GEOLOGIST – Coal Resources Department

( supervisor: Senior Geologist) 

February 1988 to August 1988,

·       Preparation of structural sections for Leigh Creek Coalfield. This required interpretation of geophysical borehole logs, database creation, computer plotting, and then seam correlation and data checking.

·       Wrote reports on the Lochiel Trial Pit

·       Supervised a kaolin exploration programme on Yorke Peninsula, South Australia.

·       Participated in a number of  data management tasks.

June 1986 to Jan 1988

I was part of the Lochiel Trial Pit task force.  This project was to excavate bulk coal samples and large scale field test dewatering and depressurisation techniques in the Northern St Vincent Basin.  The work was notable for the large amount of instrumentation used in the geotechnical and hydro-geological investigation and the low strength of the materials excavated. In particular I was responsible for

·       Installation of geotechnical instruments

·       The instrumentation management, data collection and processing.

·       Site supervisor for up to 10 contractors.

The work required particular attention to timeliness. In 1986, at the site of the Lochiel Trial Pit, over one hundred piezometers and instruments were required to monitor the different formations within the Northern St Vincent Basin and underlying basement. The formations, between 10 and 100 metres depth, were expansive and the drilling, instrument preparation and grouting had to occur within a ten minutes before the hole closed over. I was responsible for the drilling supervision, installation and testing of them all.

The key to meeting these deadlines was preparation. The grouting materials conveyed to the site included 30% contingency and the instruments were assembled and laid out beside the hole before the drilling rods were pulled. The drilling rig crew volunteered for their jobs and then a quick role play was carried out to make sure each person in the team knew their duty. If a different device caused a problem I would talk it over with the driller and take any suggestion from the crew before I modified the roles.

Only two out of one hundred instruments failed at time of installation. I excavated the in-pit instruments myself and found at most only half a dozen more that could have had some kind of hydraulic connectivity with the surface or an adjacent formation. The Electricity Trust of South Australia was given an award by the Institute of Engineers for the degree and intensity of the geotechnical instrumentation, which at that time was possibly the most intense site ever.

January 1986 to May 1986

As probation I worked as a field assistant in a coal quality and geotechnical drilling programme at Lochiel South, Australia. My duties included: 

·       Logging core; 

·       supervising 2 to 3 drill rigs;

·       selecting , preparing and sealing core samples for strength testing and chemical analysis

·       piesometer measurements;

·       taking oriented core with a timed sampler;

·       supervised another field assistant.

This work required a good knowledge of hydrogeology theory & practice. The drilling of development and geotechnical holes for the Electricity Trust of South Australia on Lake Bumbunga had a peculiar hydro-geological problem. The lake was fed by artesian water that percolated through joints in the basement and pressured a sub crustal, gypsum-anhydrite aquifer to ten metres head. When this was penetrated at less than ten metres the pressure and flow was so great that the drilling mud, though heavily weighted was diluted and the hole washed out around the collar. It was not the first time it had occurred. Previous exploration drilling by another company, had washed out, causing tens of square metres of damage to the lake surface had caused a moratorium on lake drilling.

As a supervising geologist I attended a half day course on drilling mud rpovided by the Baroid company. We then asked the driller to change his procedure to include pushing steel casing ahead of the drill bit. At the same time I kept a close eye on the chip return looking for the large anhydrite crystals that characterised the aquifer as compared the more granular, halite aquitard at the surface. Immediately there was any sign of this, very heavy barite slurry was added to the drilling mud. On practice the casing could be driven below ten metres and by twelve metres there was enough weight in the well to allow for any fluctuations in the drilling system. With these preparations the remainder of the holes were drilled without incident.

1983 - 1985          technician, Century Geophysical Australia

I was initially employed as a technician then promoted to senior technician (supervisor: Managing Director). Of particular interest to me was the geophysical logging for environmental and development studies over the period 1984-1985, where I worked on projects in three countries including the Jabiru Oil Field Offshore Storage Facility (Timor Sea), OK Tedi tailings dam (Papua New Guinea), the Sweetwater Mercury Outboard plant (Oklahoma), the Leigh Creek Coalfield (South Australia), the Lochiel Trial Pit (South Australia) and the Oaklands Joint Venture (New South Wales).
