Selected Engineering Decisions
A selection of engineering work chosen for its impact on development and asset decisions, not its complexity. Details are generalized to respect employer confidentiality — the engineering reasoning is real.
A new development well was planned to improve recovery from an existing gas reservoir. I contributed to an integrated reservoir engineering study combining geological interpretation, pressure transient analysis, and production behaviour to test the reservoir's continuity. The study demonstrated that the target area was compartmentalized, and that the proposed well would not effectively drain additional reserves. The engineering recommendation supported cancelling the planned well — avoiding unnecessary capital expenditure and sharpening the understanding of the reservoir's architecture for future development planning.
A candidate well showed limited natural deliverability despite solid static reserves. I contributed to stimulation candidate evaluation and fracture design by integrating reservoir characterization, pressure behaviour, completion strategy, and production analysis — defining stimulation objectives and evaluating expected productivity improvements ahead of the treatment. Post-fracture performance was then assessed against those expectations, an integrated reservoir and production engineering contribution rather than a standalone completions exercise.
A previously overlooked gas well had been excluded from future development planning based on an earlier read of its performance. I re-evaluated the well using updated reservoir understanding, production history, and pressure data. The reassessment demonstrated real remaining production potential and supported bringing the well back into the development plan — recovering value from an existing asset through engineering analysis rather than new drilling.
Reservoir performance doesn't hold still. Production history, pressure monitoring, and simulation only have value when integrated continuously rather than reviewed as isolated snapshots. Sustained surveillance across the well portfolio keeps that picture current — catching a well's behaviour diverging from expectation early enough to act on it, and keeping reservoir understanding, and the decisions built on it, ahead of where the original plan assumed the field would be.
One of the major field development initiatives involved reducing the Central Processing Facility (CPF) inlet pressure from approximately 62 barg to around 15 barg through the implementation of compression facilities. I prepared a comprehensive reservoir engineering guideline defining the technical framework for safely implementing this pressure reduction — evaluating the impact of increased reservoir drawdown on well performance, depletion behaviour, long-term recovery, and production sustainability. The guideline established engineering criteria for pressure reduction, surveillance requirements, production monitoring, operating envelopes, and decision-making workflows, coordinated across reservoir and production engineering disciplines, so the boosting objectives could be met without compromising reservoir integrity.
