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.

Project showcase: Development of big bore gas wells

What We Did

As part of Woodside Energy’s field development plans, Add Energy supported Woodside’s Drilling and Completion team with the well engineering services for the successful delivery of a new subsea big bore gas well.

The Results

The work provided by Add Energy supported Woodside in the successful delivery of a subsea big bore gas well. In addition to delivering the project within budget, Add Energy achieved:

  • No lost time incidents
  • Top quartile results

Working smarter with less to maximize production and assure well control

Our team of blowout contingency experts recently attended and presented at the 2020 IADC Well Control Conference. In this blog, Martin Myrvang, Senior Engineer in Add Energy, and co-presenter at the event, shares key themes and takeaways from the event and solutions to the challenges discussed.

5 daily habits of an effective Drilling Manager

It takes a highly motivated, dynamic and experienced individual to be a successful Drilling Manager. Not only do Drilling Managers have to ensure drilling operations are carried out in accordance with approved procedures and industry standards, but it is key for this to be completed in the most efficient and effective way possible.

Top considerations for an effective blowout contingency plan

A well thought out blowout contingency plan (BCP) forms the foundation of rapid and effective response if an unplanned hydrocarbon release should occur.

How to reduce response time when the unthinkable happens

An uncontrolled hydrocarbon release is one of the worst possible scenarios that an operating facility can experience. Not only are the safety barriers compromised, exposing the asset and people to significantly more risk, but the economic, business and environmental consequences can be detrimental.

A closer look at the RWIS design, how it works and the benefits that can be unlocked

A closer look at the RWIS design, how it works and the benefits that can be unlocked

Drilling and extraction of hydrocarbons is a complex and risky process, and operators must have robust safety assurance and contingency measures in place to mitigate danger, efficiently respond to any incidents and reduce the personal, business and environmental impact if an uncontrolled release were to occur.

In certain regions of the world, and for some operators, regulations and internal procedures mandate that fields cannot be developed unless the operator can demonstrate that the well can be intercepted and controlled via a single relief well drilling operation, as opposed to multiple relief wells, which is usually the norm.

Preventing a blowout while maximising flow: insights from our EVP of Well Control, Morten Haug Emilsen

Safety is always the number one priority in drilling operations, but this can often impact an operator’s ability to reach their targets and optimize future production. However, there are ways engineers can increase the efficiency of field development and maximise production, without compromising safety.

Relief Well Challenges and Solutions for Subsea Big-Bore Field Developments

Production optimization with less CAPEX is an ever-growing quest for many operators. Not only are operators focused on maximizing flow rates through larger bores, but they want to achieve this with less investment.

Whilst production optimization creates significant cost benefits for a business, it is critical to note that additional risks are introduced when bigger bores are developed. These include, but are not limited to:
