Underlying the decline curve equations is an expectation that well-production typically follows a three-part pattern. ... as pressure stays nearly constant.
Click here to enlarge image. The J-function, Equation 1 (Equation box), was originally proposed as a means of converting all capillary pressure data for clean sand to a universal curve.
The capillary pressure at each point along the plug at hydrodynamic equilibrium is obtained from Equation (1). In the above equation, P c (r) is the capillary pressure at any given radial position, Δρ ...
November 4, 2009 (New York, New York and Leicester, United Kingdom) — Hypertension doctors are once again clashing over the phenomenon of the J-curve, the concept that there is a "normal" blood ...
