Blowout Contingency

We perform transient multiphase flow simulations for blowout contingency as a preventive measure to reduce the cost and risk associated with drilling operations.

Blowout and well 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

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.

Blowout contingency planning

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. Read more

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. Read more

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. Read more

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 & 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. Read more

Training

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

PROJECT SHOWCASE

Project

We were asked to evaluate and design a casing magnetization job for a major Norwegian operator – a shallow gas reservoir was to be explored where design of relief well for potential blowout was extremely challenging, including a difficult ranging process.

What we did

We designed a relief well based on passive magnetic ranging and magnetized the casing shoe track to prepare the well for challenging ranging operations.

Result

This work enabled the operator to obtain consent to drill the well and explore the resources.
