Capabilities Spanning the Full Well Reactivation Cycle

From candidate well selection to volume reconciliation at the sales point — every stage runs to consistent engineering practice and HSSE standards.

Services and Capabilities

Five Stages, One Chain of Accountability

All five capabilities are delivered by the same team, so no technical context is lost when work moves between stages.

01

Screening & Subsurface

Candidate selection, well data review, target zones, and technical risk.

  • Idle well candidate selection based on historical data
  • Well data review and well integrity assessment
  • Definition of target production zones
  • Identification and mitigation of technical risk
02

Well Service

Clean-out, sand bailer, scraper, swab test, and potential evaluation.

  • Clean-out and wellbore cleaning
  • Sand bailer and scraper runs
  • Swab test to confirm inflow
  • Potential evaluation ahead of the production stage
03

Artificial Lift

Selection and installation of the lift method that suits the well.

  • Selection of a suitable artificial lift method
  • Equipment installation and commissioning
  • Adjustment to each well's characteristics
  • Post-installation performance evaluation
04

Production Operations

Start-up, monitoring, optimisation, maintenance, and volume recording.

  • Well start-up and production stabilisation
  • Daily monitoring of operating parameters
  • Facility optimisation and maintenance
  • Daily production volume recording
05

Lifting & Reconciliation

Delivery, custody transfer point, sales point, and reconciliation.

  • Delivery from field storage
  • Handover at the custody transfer point
  • Delivery to the receiving point and sales point
  • Volume reconciliation as the basis for calculation
HSSE

Embedded across Every Stage

HSSE is not a separate stage. Risk assessment, permit to work, and incident reporting run through all five capabilities above.

Cooperation Framework

An Operating Model Oriented to Verified Production

A clear division of roles aligns investment, technical execution, oil ownership, and performance-based remuneration.

PESI

  • Provides the investment and technology
  • Carries out reactivation and operations
  • Bears execution risk under the contract

Production

  • Volumes are measured and reconciled
  • Operations follow HSSE & engineering practice
  • Performance is the basis for remuneration

Pertamina

  • The oil remains Pertamina's property
  • Custody transfer and offtake stay controlled
  • PESI remuneration is tied to volume and ICP
Guiding Principle

Payment follows verified production — not cost recovery.

The scheme places execution risk on PESI and ensures the field owner pays only for incremental production that is genuinely measured.

Production and Lifting Chain

Operations Connected through to Custody Transfer and Sales Point

Volume reconciliation preserves traceability from field production through to the basis for remuneration.

Traceability That Stands Up to Audit

Every volume leaving the field is recorded and reconciled. Those records form the single basis for calculating remuneration, leaving no room for differing interpretations between operator and field owner.

  • Daily volume recording at well level
  • Documented handover at each point
  • Periodic reconciliation with the field owner
