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, ...
The Difference Between Variable Valve Timing (VVT) And Variable Valve Lift (VVL), Plus How They Work
Variable valve timing (VVT) and variable valve lift (VVL) have very similar names, both referring to variable valve performance. Does that mean that they are basically the same thing? The are most ...
