In this GATEKEEPER, the philosophy around the materials selection and corrosion monitoring is discussed as the primary design barrier to corrosion and cracking in critical parts of a subsea system.

This series of two articles discusses the diagnosis, detection and remediation of oil and gas production system blockages in detail. The current issue focuses on blockage characterization and detection.

This book is an exploration of what decision theory has to say about these and other common engineering problems.

The GATE Stream-based HAZOP process avoids these pitfalls via some novel modifications to the process. You can obtain a copy of the book here.

The following material properties are important when understanding the limitations of API 5CT high strength steels: yield strength (YS), Charpy V-notch (CVN) impact energy, hardness and tempering.

This GATEKEEPER article focuses on the prediction, prevention and remediation of liquid loading, including discussion of liquid loading analysis.

An empirical method for improving the predictability of NACE TM0177 Method A Tensile tests on modified 13Cr 110 ksi grade martensitic stainless steels based on an H2S/Chloride/pH function has previously been developed based on published data in order to address this uncertainty.

The objective of this GATEKEEPER is to provide a high-level overview of the model commonly used in the industry to estimate the wax deposition.

The design and development of a viable, robust wax management strategy relies upon the economical evaluation of available management techniques.

Wax management strategies developed during Front End Engineering Design (FEED) can mitigate or perhaps even prevent these costs. The goal of this GATEKEEPER series is to provide high-level insight into the planning, execution, and maintenance of wax management strategies.

The mechanisms that can lead to catastrophic failures of equipment in the oil and gas industry due to the presence of mercury are briefly presented in this GATEKEEPER.

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.

One of the primary flow assurance challenges in the production of hydrocarbons is the prevention of pipeline blockages.

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.

Triaxial evaluation of loads is used extensively for casing and tubing string design and analysis. The paper presents a method of determining the triaxially based collapse strength of casing and tubing subjected to simultaneous axial and internal pressure loads.

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.

Efficient access to multiple permeable natural gas zones located in deep, over pressured, and extremely corrosive environments presents a challenge for South Texas operating companies.

Vacuum insulated tubing (VIT) has been used successfully to mitigate the potentially harmful effects of annular pressure buildup (APB). In a recent deepwater installation, the subject well had lost alternate APB mitigation capability through a series of events. VIT was then chosen as the only viable technology.
