04 — Field Development

From reservoir understanding to a development strategy.

Field development brings subsurface understanding, well architecture, production strategy and facilities requirements together into an executable plan for developing the asset.

Integrated development

The field is developed as one system.

A field development plan is not simply a collection of wells. It is an integrated engineering decision covering the reservoir, wells, production system, facilities, economics, operational constraints and uncertainty.

The objective is to establish a development strategy that can safely and economically recover the resource while providing sufficient flexibility to respond to what the field actually does during production.

Development workflow

From concept selection to execution readiness.

Development decisions progressively convert geological and reservoir evidence into a practical programme for wells, facilities and production.

01

Development Concept Selection

Translate the geological and reservoir understanding into a practical development concept for the asset.

Key activities

  • Development concept screening
  • Development area and reservoir coverage
  • Production and injection philosophy
  • Well architecture and development options
  • Concept selection under uncertainty
02

Field Development Planning

Define how the field will be developed, produced, monitored and managed throughout its productive life.

Key activities

  • Field development plan
  • Well count and well placement
  • Production and injection strategy
  • Development phasing
  • Reservoir management strategy
03

Well and Reservoir Strategy

Integrate reservoir behaviour with well placement, completion requirements and production targets.

Key activities

  • Producer and injector placement
  • Well spacing and drainage strategy
  • Infill and step-out opportunities
  • Completion and stimulation requirements
  • Production and injection forecasts
04

Facilities & Production Concept

Establish the surface facilities and production system required to safely handle the expected field fluids and rates.

Key activities

  • Production facilities concept
  • Gathering and processing requirements
  • Export and transportation concept
  • Water and gas handling
  • Flow assurance considerations
05

Economics, Risk & Uncertainty

Evaluate technical and commercial uncertainty before committing the field to a development strategy.

Key activities

  • CAPEX and OPEX assessment
  • Production and reserves scenarios
  • Economic sensitivities
  • Technical and operational risks
  • Decision uncertainty and contingencies
06

Development Readiness

Convert the selected development concept into an executable programme ready for detailed well planning and implementation.

Key activities

  • Development programme definition
  • Well delivery sequence
  • Facilities implementation planning
  • Procurement and execution interfaces
  • Readiness for drilling and production

Integrated disciplines

Development decisions cross engineering boundaries.

Field development requires coordinated decisions across subsurface, wells, production, facilities, economics and operations.

Development decision

The plan must answer the engineering questions that matter.

01

What development concept best matches the reservoir?

02

How many wells are required and where should they be placed?

03

How should production and injection be managed?

04

What facilities are required to handle the expected fluids and rates?

05

How does the development perform under different technical and economic scenarios?

06

What must be resolved before moving into well planning and drilling?

05 — Well Planning & Drilling

Once the development strategy is established, the focus moves to designing and executing the wells required to access the reservoir safely and effectively.
