Field development planning
Specialist well-engineering input supporting field-development planning: expected pressure-management and wellbore-stability challenges, preliminary drilling and tripping strategy, hydraulic-modelling and operating-envelope requirements, and the rig modifications, equipment, risk reviews, training and readiness activities implied by them.
Where it ends
The specialist drilling-engineering contribution — not ownership of the reservoir, facilities, commercial or overall FDP approval process.
AFEs, well costs, schedules and budgets
Preparing the technical, cost and schedule inputs that support AFEs and well-cost estimates: technical and economic feasibility, engineering and equipment definition, personnel, training, mobilisation and rig-integration requirements, tender and vendor-scope review, technical bid evaluation, equipment manifests, rig-up sequences and critical-path implications — and the cost and schedule consequences of alternative concepts.
Where it ends
The pressure-drilling scope and technical basis used in the AFE — not ownership of the complete well AFE, nor final approval authority for the operator’s drilling budget.
