Our services

We bring clarity and safety to the subsurface.
At Apex Wells, we bring together some of the best wells professionals in the industry to deliver independent, high-value support throughout the entire well lifecycle. Our experience spans oil & gas, geothermal, and carbon capture & storage (CCS) projects — from exploration drilling to late-life decommissioning. We combine technical excellence with a flexible, pragmatic approach, ensuring that every solution is tailored, regulator-ready, and operationally robust.
01 Well Engineering
From the earliest concept studies to final execution, our engineering services are designed to deliver wells that are safe, efficient, and fit-for-purpose. We work closely with operators to develop cost-effective designs that optimise drilling performance and minimise operational risk. Our well engineering expertise includes:
Conceptual, front-end, and detailed well design
Drilling programme development and operational planning
Cost estimation and AFE preparation
Contractor interface management and performance monitoring
Real-time operational support and post-well reviews


02 Well Integrity
Well integrity is fundamental to safety, environmental protection, and regulatory compliance. Apex Wells provides independent, objective assessments to help operators maintain barrier integrity throughout the well’s life.
Our approach combines regulatory knowledge with practical, hands-on experience to identify risks early and propose workable solutions.
Lifecycle integrity management and strategy development
Barrier verification and well integrity audits
Diagnostic investigations and failure analysis
Remediation and workover planning
Risk assessments for well interventions and late-life assets
03 Well Examination
As an independent well examiner, Apex Wells provides impartial assurance that wells are designed, constructed, operated, and maintained in line with legal and industry standards. Our well examination services are tailored to meet the specific requirements of the Dutch Mining Act, the UK Offshore Safety Case Regulations, and other international frameworks.
Examination of well designs before operations commence
Verification of well construction and completion against approved programmes
Periodic reviews of operational wells to confirm ongoing integrity
Examination of suspension, abandonment, and decommissioning plans
Documentation and reporting suitable for regulatory submission


04 Well Decommissioning
Well integrity is fundamental to safety, environmental protection, and regulatory compliance. Apex Wells provides independent, objective assessments to help operators maintain barrier integrity throughout the well’s life.
Our approach combines regulatory knowledge with practical, hands-on experience to identify risks early and propose workable solutions.
Abandonment feasibility studies and cost modelling
Plug and abandonment (P&A) design and engineering
Barrier verification and compliance assurance
Contractor selection and execution oversight
Environmental risk assessments and regulatory submissions
