Gate valve bonnet failures from thermal expansion of fluids at high temperature - In a steam-assisted gravity drainage application, immediately after start-up, a gate valve bonnet failure caused a release of pressure to atmosphere. In thermal applications throughout the oil and gas industry, there have been incidents of valve failures during start-up. Resulting damage can include stretching studs and loss of pressure integrity between the body and bonnet. The main cause is pressure build-up in the gate valve cavity from thermal expansion of fluids, which was completely full and isolated. Such pressure exceeded the rated working pressure of the valve.(more...)

A three phase separator.

Produced well fluids typically contain a varied amount of oil, produced water, natural gas and sediment. The first step in processing these fluids is to split them up into individual components. This generally takes place at some types of separator. A three phase separator uses gravity to separate produced well fluids into gas, oil, and water phases.


Three phase separators may be designed in either vertical or horizontal configurations. In a horizontal separator, fluid enters the vessel and hits an inlet diverter. The resulting sudden change in momentum provides the initial gross separator of liquid and vapor. The liquid collection section of the vessel must provide sufficient for the oil and emulsion to form a layer or pad above the water. A weir maintains the oil level while an interface controller maintains the water level... (more...)

Featured Technology of the Week

Deepreach.png
Halliburton's DeepReach™ Coiled Tubing Servic uses multiple outer diameter coiled tubing sections in a single string with larger OD sections near the top of the string and smaller OD sections near the bottom.With this arrangement, the tension along the string length is reduced while sufficient flow capacity is retained for performing well intervention operations.

Tapered OD Makes the Difference

The vertical depth capability of conventional coiled tubing is limited because as the length of the tubing string increases in the well, the string’s total weight also increases; therefore, the capability of a conventional CT string to perform ultra-deep work depends primarily on the string’s total hanging weight and the yield strength of the parent metal. If the hanging weight exceeds the pipe’s yield strength, a string separation can occur. Since a tapered coiled tubing string is lighter in weight (compared to a single string of the largest diameter) and its design provides greater strength at the upper end of string, operators can realize up to a 30 percent increase in depth capability over conventional CT strings.

Key Enabling Technologies

Multiple technologies were developed to enable DeepReach coiled tubing to be used in deep well operations. These technologies

include 1) the CT transition joints, 2) Boots & Coots V-Block® gripper design, (more...)
