A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

This letter refers to an article by Zotan Turzo and Gabor Takacs entitled "CFD techniques determine gas-lift valve behavior" (OGJ, June 8, 2009, p. 46). The article stated: "Mainly based on the ...

Due to age and corrosion, the main gas shut-off valve in up to 10% of California homes is frozen so tight that the average homeowner cannot move it to the closed position, according to a Public ...

Key insight: All lift systems target the same physics: reduce mixture density or add head so that nodal balance at the wellbore yields the desired rate. 2.3 Select lift method aligned to fluid, depth, ...

OTC in Houston is the meeting place of the great and the good from the oil and gas industry. Now in its fiftieth year it is the must attend event for anyone involved in the oil and gas sector, and ...

Typically, a well will produce at its highest production rate at the beginning of the production cycle; and then production will wane. In an effort to increase production from both oil and natural gas ...
