Henry’s Full CV

Technical Publications List

Ravva Field Development

• Provided input to tender preparation and evaluation for the Ravva Facilities EPIC contract, Drilling, Data Acquisition(coring, logging, testing), Well Services (including CH wireline), and Core and Fluid Analysis Contracts.
• Prepared detailed procedures for CoreHandling/Processing, Drillstem and Wireline testing, and Slickline Pressure surveys for use by the national staff.
• Carried out preliminary gas lift design for tubing and equipment sizing.
• Established the company’s technical credentials in the Petroleum Engineering area with the Joint Venture and Government, and achieved excellent rapport with their representatives, through technical workshops and clear communications.  This was despite the very different approaches to Development Planning, Data Acquisition and Reservoir Management.  In particular, were solved their serious concerns re well and reservoir flow rates.
• Obtained timely JV approvals for the development, exploration and appraisal wells (in close conjunction with Geoscience staff), workovers and completions.
• Established close liaison with our Geoscience staff to permit a truly integrated reservoir description.  Extensive use of production and pressure data allowed definition of fluid systems, reservoir continuity and boundaries.
• Conducted studies re injection source groundwater wells, water compatibility and treatment.  Specified, tendered and awarded the groundwater well drilling and arranged technical supervision.  Provided guidance and quality control for commissioning of the water injection system and monitoring of injection well performance.
• Assisted with studies re sand production prediction, well capacity testing and sand monitoring procedures, and reviewed gravel packing procedures.
• Directed and ensured quality control of an extensive reservoir surveillance programme at Ravva.  The pressure data quality achieved allowed valid conclusions to be reached by comparison of well pressures that are only a1-2 psi apart.  Analysed an extensive suite of pressure buildup, falloff, interference and pulse tests, and production and RST logs.
• Carried out multi-reservoir linked material balance studies, participated in/supervised three major simulation studies, and presented/gained JV approval for the conclusions.
• Supervised 1 – 3 technical staff in Sydney and mentored 5 Madras Petroleum Engineers.
• Prepared an Updated Ravva Development Plan including recommendations for a production rate increase and associated investments.  Obtained Operating Committee and Government approval.
• Had a major role in complex negotiations for a gas sales contract with Gas Authority of India Ltd.

AWE

• Was on long term (17 years) contract with AWE providing reservoir management advice for all of AWE’s producing assets, exploration and new venture evaluations. At various stages, seconded to AWE JV partners, e.g. ROC Oil for the Cliff Head Field Reservoir Development Plan; Transworld for the Tui Area Reservoir Development Plan; and Origin for the Yolla and Trefoil simulation studies. Participated in the evaluation, acquisition and reservoir development planning for the Ande Ande Lumut field in Indonesia, including subsequent successful divestment of 50%.

Esso Technical Computing Group

• Henry joined the Production Department Technical Computing Services Group and was promoted to Group  Supervisor 10 months later.
• Developed EAL (now Exxon Mobil) technical software, provided support for Exxon and other software packages, organised Production Department computing and data communications hardware, and liaised with EAL Information Systems Department.
• Developed a Production System Optimisation/Forecasting and Gaslift Allocation program,and a Production/Processing Material Balance and Royalty/Excise System (both used for 15+ years).
• Debugged, enhanced and supported the local version of Exxon’s reservoir simulation program, including provision of advice on convergence and efficient modelling.

Esso Reservoir Engineering

• Henry transferred to the Reservoir Engineering Group as Reservoir Developments Supervisor in January 1980, with 5 – 10 reservoir engineers in the group. At the time Mackerel and Tuna development drilling was in progress and these were followed by Snapper, West Kingfish, Cobia, Fortescue, and Flounder development. 
• Responsibilities included close liaison with Production Geology to define well locations, well and reservoir data acquisition and analysis, specification of completions and facilities requirements, and obtaining JV and Government approvals.
• Introduced the use of RFT pressure profiling in deviated wells at Tuna against strong operational opposition.  This vital data allowed definition of fluid systems and contacts for the over 30 additional pools discovered during development drilling.  Snapper field was also a challenging development with a 6.5 m pancake oil column, concurrent gas cap and oil zone production, and highly variable well producing characteristics.
• Reviewed and implemented revised methodologies for Reserve Probability Analysis.
• Prepared the development plan for the West Tuna field and the Bream field, both stratigraphically complex thin oil column reservoir.
• Supervised the Reservoir Studies Group (also within Reservoir Engineering), comprising 4 – 7 engineers, from late 1984.  Responsibilities included field simulation studies (including Mackerel, Fortescue, Halibut/Cobia, Snapper, Kingfish and West Kingfish and other minor field/segment models), development feasibility studies (including Perch, Dolphin, Whiting, Tarwhine, Seahorse, Blackback, Yellowtail, Mulloway), reservoir management, reserves reporting, and Government/JV liaison.
• Responsible for the development drilling phase of Bream. This successful development considerably exceeded its reserves and production targets.  Justified the drilling of 5 horizontal wells, the first by EAL. 
• Completed and gained Corporate Approval for the development plans for West Tuna and Bream B (projects cancelled after the 1986 oil price crunch and re-worked some years later).
• Gained Government approval for field production rate increases including Snapper, West Kingfish, Cobia, Fortescue and Bream.
• Prepared three successful “New Oil”classification applications.
• Evaluated a number of discovered field acquisition opportunities. Led the reservoir evaluation team resulting in the successful acquisition of an interest in Jabiru and Challis.
• Primary contact for exploration support activities, including prospect evaluations, well evaluation (coring, wireline and production testing decisions), and appraisal well decisions.  Primary contact with the Gas Marketing Department.
• Seconded as lead EAL representative in the Resource Optimisation Study.  This joint EAL/EPRCo task force evaluated reserve growth opportunities, including marginal fields, infill drilling, attic recovery, and near miscible gas injection projects.
• Prepared the technical case and appeared as a technical witness for Esso in court proceedings relating to an excise dispute.
• Prepared and delivered the Field Development Planning section of the Exxon wide, inaugural Applied Reservoir Management School.

Data Analysis Pty Ltd – December 1968 to August 1973

• Carried out software development, statistic analysis, data processing and client liaison for the computer service bureau side of this small Mining and Petroleum industry consulting business. 
• Appointed to run the bureau side of the business (other than financial) in 1970, with 2 – 4 staff reporting to me.
• Developed innovative software for geostatistics, processing of aeromagnetic data, contour mapping, interpretation of Dipmeter data, open cut mine optimisation, and digitising, editing and display of seismic interpretation data.  The dipmeter processing program proved very popular and by 1973 Data Analysis was processing almost all of the 4-arm dipmeter data in Australia.
