Abstract: High-pressure and high-temperature (HPHT) deepwater oil and gas wells are under the influence of high-temperature formation fluid after putting into production. The thermal expansion pressure of sealed annular fluids caused by the annulus temperature change… read more here.

Abstract: Abstract Tubing leakage is one of the main reasons to cause annular pressure in HPHT gas wells. This kind of annular pressure is called “sustained” because it is long-lasting and can not be eliminated by… read more here.
