Blowout Contingency

Preparing your organization for the unthinkable

Reduce response time in the event of an incident

Assure competency to minimize risk

Reduce costs associated with drilling and intervention

Identify the most efficient and effective contingency measures for your business

We perform studies and deliver solutions for blowout contingency, as a preventive measure to reduce the cost and risk associated with drilling operations.

Blowout and Kill Simulations

We perform transient multiphase flow simulations of hypothetical blowout scenarios to identify and evaluate potential flow rates and kill requirements by use of our unique software, OLGA®-WELL-KILL, which is tailor-made for well and well control simulations.

Relief Well Planning and Solutions

We develop detailed relief well plans from the basis of our experience with actual incidents. The relief well plans will identify potential constraints and propose design solutions with details on spud locations, well trajectories, ranging (homing in) strategies and intersection methods.

The RWIS (Relief Well Injection Spool)

A patented piece of specialist subsea equipment that enables operators to stop a blowout from prolific reservoirs safely and efficiently via a single relief well.

Blowout Contingency Planning and Solutions

We develop detailed blowout contingency plans that meet operator specific requirements and governmental regulations and standards (e.g. NORSOK D-010). Blowout contingency plans will typically include identification of potential scenarios with evaluations of intervention methods, mitigation options and kill requirements.

Simulations while Drilling

We perform real time simulations based on MWD data to reduce the cost and risk associated with drilling operations, for example; provide the required support for drilling the entire reservoir section without setting an additional casing string.

Casing Magnetization

We pre-magnetize casing as a preventive measure to reduce the cost and risk associated with relief well drilling operations. A pre-magnetized casing will improve the likelihood of a successful intersection, especially in challenging ranging situations such as shallow reservoirs and salt formations.

Spill Drill Support

We participate as an integral part of spill drill teams and share our extensive experience from live incidents combined with transient flow simulation competence. Outcome of our contribution includes soft shut-in procedures and cap and containment design.

BOP and Well Control Equipment Audits

We verify that the BOP and its associated well control equipment are maintained, inspected, certified and tested in compliance with regulatory requirements and international standards.

Blowout Contingency Training

We offer advanced training courses in the area of blowout contingency and regulatory requirements (e.g. Principles and contents of NORSOK D-010).

“Gaining access rights to the RWIS, as a contingency measure, enabled us to build a business case for larger wells to be developed, allowing us to meet production targets with less investment.”

Project Showcase: Unlocking Drilling and Exploration Capabilities

Project Goal

To evaluate and design casing magnetization requirements for a major Norwegian operator, a shallow gas reservoir was to be explored where the design of relief well for potential blowout was extremely challenging, due to difficulties associated with ranging and detection.

What We Did

Add Energy designed a relief well utilizing passive magnetic ranging techniques and magnetized the casing shoe track to prepare the well for challenging ranging operations

The Result

The magnetization enabled the operator to obtain consent for drilling and exploration.

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

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:
