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 ...

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, ...

A leaking natural gas well that has displaced thousands of residents in Porter Ranch lacked a working safety valve, sparking new questions about how the facility was maintained. Attorneys for ...
