Our well engineering experts design, plan and manage all types of exploration, production, storage and disposal wells, across vertical, horizontal or multi-laterals; depleted reservoir or HPHT; onshore or offshore; subsea or platform; shallow or deep water; remote location and harsh environments.

Concept, Screening, Feasibility and Field Development Studies

We create a range of development scenarios covering different well designs, rig strategies and execution options, and link each case to accurate life of field cost estimates in order to identify optimal development options.

Well Design

We establish a design basis and utilize experience from offset wells to optimize hole sizes, well profile, sections lengths, casing/liner sizes, mud and cement to achieve the objectives of the well (explore, produce, inject) in a safe and cost efficient way. Stresscheck™ as well as production load assessments (WellCat™) are used to calculate casing loads.

Completion Design

We provide a fit for purpose engineering solution to meet field development plans, lifecycle well integrity and production requirements. We select the best technology for the job, supported by tubing stress analysis, upper and lower completion design, metallurgy assessment and sand control and fluids design. WellCat™ is used to calculate temperature profiles and production tubing stresses.

Well Test Design

We specify the well test string and components and surface processing equipment to achieve the objectives of the flow test. WellCat™ is used to calculate test string loads.

Abandonment Design

We assess various abandonment solutions for single or multiple wells to ensure that we achieve a leak tight, regulatory compliant and cost efficient design. Together with our well integrity and intervention experts we can assess and rank entire well portfolios to optimize P&A strategies.

Technical Incident Investigations

We assist clients with technical investigation of unplanned events (i.e. packer or cementing failures, stuck pipe, etc.) or significant cost overruns. This may include assessments of the organisation’s capacities, competencies and structure.

Advisors and Consultants

We provide personnel to work as integrated members of our client’s team, in the office, on the rig or at the well site.
