Steady-state and transient wellbore temperatures during drilling

PDF Version Also Available for Download.

Description

An extensive literature search was made to locate technical publications and computer programs relating to wellbore temperatures during drilling operations. Publications obtained are listed in the References. Two approaches were used in calculating borehole temperatures: The steady state solution of Holmes and Swift was programmed and 2100 cases calculated for various borehole configurations. For transient temperature studies, Exxon Production Research Co. made calculations for ten borehole configurations under subcontract. These calculations emphasize the need for better high temperature bit performance and improved engineering procedures in drilling.
