Well Engineering

We design, plan and manage all types of exploration, production, storage and disposal wells: vertical, horizontal or multi-branched; depleted or HPHT; onshore or offshore; subsea or platform; shallow or deep water; remote location and harsh environment.

Concept screening, feasibility and field development studies

We develop 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™ is 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 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 over runs.

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.

Woodside, a world leader in drilling and completing subsea big bore gas wells, commenced drilling of their first big bore gas wells in 2000 and are still growing their portfolio.

What we did

add energy assisted the Woodside D&C team with the successful delivery of a new big bore gas wells in line with their field development plans.
