HAWKINS’ FORMULA FOR THE SKIN FACTOR
WebSeptember, 1996– OnePetro. Abstract This paper describes and quantifies a mechanical skin damage resulting from the redistribution of stresses caused by drilling the well. The damage is localized within a radial ring around the borehole wall. The stresses (and related positive skin), increase with depth, angle of inclination, and well production. WebIn fact, Hawking found that the black hole temperature was T = κ/ (2π), so ǫ = 1/ (2π) and hence η = 1/4. This gives the famous Bekenstein-Hawking formula for the entropy of a black hole: 1 Sbh = SBH ≡ A. (2) 4 Here the subscript bh stands for “black hole,” and the subscript BH stands for “Bekenstein-Hawking.”. devyn simone wendy williams

The equation for oil and gas wells is = It has two characteristic constants: the back pressure constant, c, and the back pressure exponent, n. The exponent n is a dimensionless number between 0.5 and 1.0. It approaches 1.0 for low rate wells and 0.5 for very high rate wells. http://scholarpedia.org/article/Bekenstein-Hawking_entropy church in san juan tx
