Chevron

2004-2009 Consultant Production Engineer

Provided Production Engineering services on contract to assist in the short to long term development of the Chevron operated Strathspey, Erskine and Caledonia North Sea Fields.

 Participate as a subsurface team member in guiding various major and minor projects through the Chevron planning process.

 Provided decision making and problem solving skills to the planning, risk assessment and execution phases of these projects

 Generated relevant technical data to allow probabilistic analysis of economic risk and return. Prosper, GAP, OFM and Crystal Ball are typical software tools which I have expertise.

 Promoting detailed well performance analysis to allow recognition of problems, generate opportunities for improvement and assist in reservoir monitoring.

 Communicating of progress and results through attendance at internal Decision Review Boards and presentation of material to partners and Government.

 Redrills, workovers, scale management and chemical treatments were part of the major wellwork themes over this period.

ChevronTexaco

Nov 2003-Feb 2004 Consultant Production Engineer

Provided Production Engineering services on contract to assist in the production of the Galley Field during the sales transition period with Talisman. Responsibilities included well performance monitoring and directing the decision making process for scale inhibition choice.

Amerada Hess

1997-2003 Consultant Production Engineer

Provided Production Engineering services on contract to assist in the short to long term development of the Amerada Hess operated Scott, Telford , Marmion and Ivanhoe/Rob Roy North Sea Fields.  Directed the process of opportunity recognition, objective setting and planning of well interventions within the Reservoir Technical Services (RTS) group.

 Promoted detailed well performance analysis to allow recognition of problems, generate opportunities for improvement and assist in reservoir monitoring.

 Performed detailed analysis of subsea well network systems using Prosper and GAP software.

 Represented RTS in the Scott/Telford development drilling planning process to ensure objectives are aligned through the drilling, evaluation and completion phases (horizontal and Thru Tubing Rotary Drilling wells included).

 Investigated and promoted methods for production enhancement.

Elf Exploration UK plc (1993-1997)

1997 Production Strategist

Responsible for investigating opportunities to increase profitability in the maturing Piper and Claymore fields. Recommendations made for management approval were as follows:-

 Process de-commissioning saving £0.5MM,

 De-bottlenecking topside systems (estimated revenue acceleration of £18 MM)

 Feasibility of producing from the high H2S Crathes field to the Claymore platform

1995-6 Staff Well Performance Engineer

Previous communications role expanded to include both Piper and Claymore areas. Ensured development drilling, workovers and minor wellwork were economically justified and prioritised in order to satisfy reservoir management and production goals. Achieved agreed production targets within annual budget of £60MM.

Reinforced the decision making process for well workover and repair by formalising the selection and justification procedure (involved £10MM of well work).

Reviewed gas lift usage on Claymore and proposed long term plan for reduction.

1993-4 Staff Subsurface Engineer

Following re-organisation, promoted to the Claymore Asset management team.

Tasked with managing communications between the Asset and other functional departments to ensure production and reservoir management goals were achieved within the allocated annual well work budget of £40 MM. Successfully established as the focus of a multi-disciplinary team for all development drilling and well work planning, chairing regular meetings to direct, control and influence the decision making process. Production targets of 27 and 25 MMstb were achieved in 1993 and 1994 respectively. Co-ordinated a reservoir management strategy “peer review” of the Claymore and Scapa fields leading to a presentation of recommendations to senior management.

Occidental Caledonia Petroleum Ltd. (1979-1992)

1991-2 Engineering Advisor. (Elf acquisition completed 2 July,1991)

Tasked with advising section head on all aspects of well performance on Claymore.

Completed feasibility studies on two potential Claymore subsea satellite developments.

Reviewed alternative artificial lift method to gas lift and made technical and commercial recommendations.

Co-ordinated reservoir and production data input into creating development plays for prospects in the 14th Round Evaluation.

Successfully planned and co-ordinated the second phase appraisal testing of West Scapa with a potential £20MM development.

1990 Senior Petroleum Engineer

Supervised a team of three engineers responsible for maintaining and forecasting gas lifted well production from the Claymore and Scapa fields ( 87,000 stbopd).

Successfully planned and co-ordinated the first phase of the West Scapa appraisal testing.
