Pegasus Vertex, Inc. developed ctemp software to predict wellbore circulating temperatures, essential for high-pressure, high-temperature (HPHT) drilling operations. The software models transient heat transfer and accounts for complex factors like flow paths and environmental conditions, providing vital operational guidelines. ctemp is compatible with various Windows systems and designed for both land and offshore wells.

CTEMP
Circulation Temperature
As the search for petroleum resources become more extreme in terms of depths, pressures,
and temperatures (HPHT drilling), wellbore circulating temperature prediction becomes very
crucial. It has implications for flow assurance (wax, hydrates, viscosity), stress analysis,
drilling tool temperature tolerance, completion fluid density, cementing, and other variables.
Predicting circulating temperature in deepwater wells is further complicated by the presence
of risers and choke/kill/boost lines.
Pegasus Vertex, Inc. (PVI) is leading the way with software technology by developing
CTEMP, which predicts the wellbore circulating temperature for drilling/circulating operations.
CTEMP addresses the transient heat transfer between the wellbore and the sea water/rock
formation. CTEMP’s interactive on-screen graphic results provide operation guidelines for
expensive HPHT drilling operations.
