Well Intervention, Completions & Decommissioning Execution Support

Execution-focused support across well intervention, completions, workovers, and production enhancement — extending through to late-life and decommissioning delivery.

Intervention Performance supports operators during complex, high-risk, or execution-critical phases of well operations — where delivery certainty, operational alignment, and experienced oversight are required.

Engagements typically include campaign planning, offshore execution support, optimization of well intervention, completions, workover, and production enhancement activities, as well as late-life / P&A readiness — particularly where standard approaches are insufficient or risk exposure is elevated.

Led by Grant Pierce, a senior wells practitioner providing independent technical assurance and execution oversight across well intervention, completions, workover, production enhancement, and late-life operations.

Execution-Focused Support Across the Well Lifecycle

Intervention Performance supports operators across the full well lifecycle, with a focus on practical execution, operational readiness, and cost-effective delivery.

Work spans well intervention, completions, workover, and production enhancement activities, as well as late-life asset management — including P&A and decommissioning preparation — aligned to real operating environments and offshore constraints.

The focus is ensuring scopes are executable, risks are identified early, and operations are delivered efficiently offshore.

Who We Support

Wells & Completions Managers

Campaign planning, execution readiness, and independent technical challenge to reduce delivery risk.

Well Intervention & LWI Leads

Intervention program design, subsea execution support, and operational oversight across complex scopes.

Asset & Late-Life Managers

Workover strategy, integrity improvement, and structured late-life and P&A readiness planning.

What We Actually Deliver

We provide targeted, execution-focused support across well intervention, completions, and late-life wells — deploying senior specialists who strengthen planning, decision-making, and offshore execution without adding unnecessary layers.

  • Well Intervention & Light Well Intervention (LWI)
    Planning, readiness, and execution support for conventional and subsea interventions, including riserless LWI campaigns, vessel operations oversight, barrier management, and non-routine intervention scopes.

  • Completions, Workovers & Production Enhancement
    Completion design challenge, workover planning, and execution assurance across greenfield and brownfield wells, with focus on operational practicality and delivery certainty.

  • Late-Life Wells & P&A Readiness
    Integrity assessment, intervention sequencing, and forward planning to reduce future abandonment cost exposure and avoid reactive, high-risk operations.

  • Campaign & Project Delivery Support
    Independent technical authority, front-end planning, and execution oversight for multi-well or high-risk campaigns under cost, schedule, or resource pressure.

How Support is Provided

Engagements are typically short-term and targeted, provided in an embedded or advisory capacity without disrupting established delivery roles or governance.

  • Embedded or advisory SME support — onshore and offshore operations
  • Planning and readiness reviews tied to execution reality
  • Real-time decision support during non-routine operations
  • Clear escalation and technical authority when required
  • Focus on reducing uncertainty, with reporting that supports execution

Independent Technical Challenge & Assurance for Decision Quality

Independent technical challenge is provided at key decision points to strengthen execution readiness, risk understanding, and decision quality.

Assurance is aligned with client governance and authority frameworks, focused on supporting delivery outcomes rather than process volume.

Clear escalation pathways and decision support when required.

Experience Where It Counts

Our experience is built on delivering wells in real operating environments — not theoretical models. We support onshore, offshore, subsea, deepwater, and mature assets across multiple regulatory, technical, and logistical contexts.

  • Asia Pacific: Vietnam, Malaysia, Indonesia, Thailand, Brunei

  • North Sea: UK and Norwegian sectors

  • West Africa: Brownfield and late-life offshore assets

  • Gulf of Mexico: Shelf and deepwater operations

  • Middle East, India & Australia: Complex wells and execution-intensive campaigns

This breadth allows us to quickly understand asset constraints, regulatory expectations, and execution risk — and to add value from day one.
