Trapped annular pressure is caused by thermal expansion due to heat transfer and has
become one of the serious challenges to well safety. In order to assess and mitigate this risk …

The evaluating methods and control technologies for trapped annular pressure (TAP) are
important part of deepwater drilling, completion, testing, production and injection. The casing …

Subsea wells use annular-pressure-buildup (APB) mitigation devices to ensure well
integrity. We define mitigation techniques that control APB by reducing lateral heat loss from …

Trapped annular pressure is caused by liquid thermal expansion in oil and gas wells. A
casing is developed to mitigate trapped annular pressure with low cost and overcome the …

Casing annulus pressure build-up owing to fluid thermal expansion in sealed annuli
severely threaten the casing safety and wellbore integrity of deepwater wells. To mitigate the …

Deepwater wells have the basic conditions for the generation of trapped annular pressure
caused by thermal expansion. Nitrogen is eligible medium to mitigate annular pressure for …

To accurately predict annular pressure build-up, which is caused by the thermal expansion
of fluid in deepwater wells, a prediction model should consider that the thermal expansion …

Annular pressure buildup (APB) is caused by heating of the trapped drilling fluids (during
production), which may lead to burst/collapse of the casing or axial ballooning, especially in …

Predicting the pressure behavior of annular fluids during production and injection operations
in oil wells became a major research topic in the exploration of deep-water reservoirs …

The electrical submersible pump's (ESP) impact on wellbore temperatures and integrity is
seldom discussed in literature. Most literature discusses ESP run life and failure. The ESP …
