Methanol (MeOH) contamination of crude oil is a growing concern in the oil and gas industry, as pipeline and refinery quality requirements become more restrictive.

GATE develops and implements DST’s to mitigate high risk exposure associated with project execution.

This GATEKEEPER provides a general overview of the epoxy coatings used in offshore oil and gas service and discusses common causes of premature coating failure as well as factors affect coating quality.

Casing and tubing that are subjected to combined loads have higher collapse strength than previous formulas would predict, permitting the use of thinner walled, or lower strength, pipe than formerly required.

In Part 1 of this GATEKEEPER series on complexity, we identified 8 key sources of project and project team complexity. In Part 2, we discuss what can be done about them.

A project consists of two interacting networks; one CPS (the kit) and one CAS (the human organization). We should expect some surprises (emergence) from the interaction of these two complex systems.

Artificial lift methods transfer energy to the produced fluid with the objectives of reducing the fluid density and the pressure head or boosting the flowing pressure.

This GATEKEEPER discusses an effective subsea tree PWV (USV) leak test method. The test can be done quickly – entire test time is about 15 minutes, including the 5 minute monitoring time.

Acidizing involves pumping acid into a wellbore or geologic formation that is capable of producing oil and/or gas. The purpose of acidizing is to improve a well’s productivity or injectivity after production has declined 4.

Annulus Pressure Management refers to an engineered approach ensuring that casing annulus pressures do not challenge the well’s integrity during the life of the well.

This GATEKEEPER discusses the various bacteria testing options that are available, which can be used to validate MPN results, as well as the mitigation and remediation techniques that can be used to decrease the probability or severity of MIC to pipeline infrastructure.

This GATEKEEPER will discuss, at a high level, the decision support tools and methodologies that can be implemented to assist in the delivery of incident free execution of projects through focused risk mitigation in the key process safety impact areas of station keeping and vessel integrity.

When properly developed, a CMMS tool can ensure that detailed equipment information is readily available, improve reliability, reduce equipment and facility downtime and more.

In order to avoid potential riser failures or replacement campaigns for anticipated service lives that may extend to 30 years or more, process facility components such as risers and flowline systems must now be subjected to more enhanced integrity monitoring through the whole of their service life.

A HAZOP is a team-based process hazard analysis (PHA) method. Its purpose is to identify hazards and operability issues in a process design.

This GATEKEEPER provides an overview of the decisions which are the truly important outcomes from this process, and outlines the risks we incur by setting our scale management and associated field design philosophies early in the life of a project.

With offshore oil and gas recovery pushing the limit with deeper and deeper water, it comes as no surprise that the technology regarding risers has evolved to meet the demands of harsher environments.

This GATEKEEPER will discuss the problems and challenges that arise from this distinct environment and the respective solutions and best practices that must be considered in order to safely and effectively deal with them.

Proper use of the program ensures that careful consideration is given to all potential project hazards and that suitable precautions are taken to minimize risk.

As new industry challenges arise, a new approach to multiphase analysis called Computational Multiphase Fluid Dynamics (CMFD) has appeared as a possible solution.
