New one-piece downhole jet pump
Here’s the new one-piece Tex-Jet downhole pump, a unit that features no moving parts and is made of 4140 heat treated, stressed relieved steel. It’s available in sizes of ¾ in. to 3½ in.
The jet pump assembly includes this unit interposed between a tubing string and a packer. It requires a fluid separator and compressor for complete operation.
In operation, compressed gas is injected into the annulus formed between the casing and the tubing string. The compressed gas forces the hydrostatic column of fluid above the packer through the angled inlet ports of the pump. It is forced into the upper tubular end and the tubing string where the compressed gas mixes with the production fluid that has been pulled up through the production ports by the compressed gas.
The mixed fluids travel up the tubing string to the surface. At the surface, the fluid exits the tubing string and is passed to the flowline and is introduced into the fluid separator. When fluid begins entering the separator, the jet pump assembly reaches a breakover point, creating suction on the wellbore. In general, 0.5 lb of pressure per foot of fluid column to be lifted is required. Once breakover point is achieved, the discharge line pressure generally drops to 125-150 psi of working pressure. Tex-Jet works in a range of depths of wells, straight wells, or deviated wells and is tolerant of sand, fines, and scale.

New line of enclosures for oil field operations
A new line of rugged enclosures is engineered for applications such as monitoring drilling rigs, compiling and processing seismic data, and maintaining pipelines.
Shielded from extreme conditions in temperature, contaminants, moisture, vibration, and radiated or emitted electrical noise, the enclosures help ensure that critical computing applications operate reliably, with minimum repairs and downtime, the company notes.
