Fatigue Failure in Gate Valves: How Failure Analysis Prevents Recurring Leaks & Improves Reliability
A client sent us a leaking gate valve with a through-wall crack that had developed after years in service.
The investigation showed the valve had failed by fatigue. The crack had been growing for some time before finally penetrating through the valve wall and creating a leak.

6 Critical Steps to Create a Successful Frac Program & Mitigate Well Failures: A Case Study
An independent oil operator experienced four back-to-back casing failures in his Oklahoma shale program. These current failures and setbacks were eating into his budget and eroding stakeholder faith in the ability to complete wells.
His initial comment was, “I’m not getting any sleep – I need some help. You’ve got to help me stop the leaks!”
Cost-Effective Gas Compression System Expansion Study
A winter-peaking natural gas storage plant undergoes a production expansion which includes infill well drilling and a gas compression system expansion.
Injection of Flue Gases Study
Led study for independent oil and gas operator regarding the injection of flue gases from Gulf coast power plants to a Deepwater development for the purposes of enhanced oil recovery (EOR). This considered pretreatment and processing requirements for flue gases from natural gas-fired boiler plants, natural gas combined cycle plants, coal-fired boiler plants and integrated gasification combined cycle plants. Key issues considered were the ability of the pretreatment system to remove oxygen and water.
Noble Energy - Aseng Waterflood Systems Engineering
GATE was responsible for developing the overall Aseng Water Injection System Basis of Design.
BHP Billiton - Neptune and Shenzi - Souring Potential Determination
GATE was requested to determine the potential risks involved in waterflood for the Neptune and Shenzi fields as a means to determine whether waterflood was a viable option for enhanced oil recovery. Based on this, GATE developed a waterflood philosophy document that details the problems and possible mitigation procedures for BHP’s use in determining whether or not to waterflood.
BP - Production Chemistry Support
GATE provided in-house production chemistry support for the Horn Mountain, Atlantis and Thunder Horse assets.
