Based on the above equation, if the OHTC [U.sub.l] = 0, [partial derivative][T.sub.rl]/[[partial derivative].sub.rl] = 0, indicating no heat flowing into or out of the rock formation.
The OHTCs [U.sub.l] can be calculated based on Willhite's equation  which considers a multilayered wellbore structure
for the horizontal well, where [[rho].sub.f] and [c.sub.f] are the mass density and specific heat capacity, respectively, of the fluid and [r.sub.tl], [A.sub.l], [U.sub.l], [v.sub.l], [T.sub.fl], and [T.sub.bl] (l = 1 for injection, l = 2 for horizontal, and l = 3 for production) denote the radius of fluid flow channel, the areas of the wellbore cross section, overall heat transfer coefficients (OHTCs), fluid velocity in the wellbore, fluid temperature, and the temperature at the wellbore wall, respectively.
Jim Twine commented: "My key motivation for joining OHTC was that I think it is a fantastic company that very much shares the values of the organic movement.
lb help gear up for growth OHTC has invested in new machinery to help increase capacity and throughput.
