CTEMP - Circulation Temperature Model

As the search for petroleum resources become more extreme in terms of depth, pressure, and temperature (HPHT drilling), wellbore circulating temperature prediction becomes a very crucial process. It has implications for flow assurance (wax, hydrates, and viscosity), stress analysis, drilling tool temperature tolerance, completion fluid density, cementing, and other variables. Predicting circulating temperature in deep-water wells is further complicated by the presence of risers and choke/kill/boost lines.

Pegasus Vertex, Inc. is leading the way with CTEMP, software that predicts wellbore circulating temperature for drilling/circulating operations. CTEMP addresses the transient heat transfer between wellbore and sea water/rock formation. Its interactive on-screen graphic results provide operation guidelines for expensive HPHT drilling operations.
