Assignee:

Landmark Graphics Corporation - Houston TX

International Classification:

E21B 33/14
E21B 41/00

Abstract:

A method for determining annular fluid expansion (“AFE”) within a borehole with a sealed casing string annulus. The method may include defining a configuration of the borehole. The method may further include defining a production operation and a borehole operation. The method may also include determining AFE within the borehole when performing the production operation. The method may further include determining AFE within the borehole when performing the borehole operation based on the AFE within the borehole when performing the production operation.

International Classification:

E21B 47/007
E21B 47/07

Abstract:

A well operation simulator predicts temperature and pressure profiles of a multi-tubing completion well for well design. The simulator is comprised of modules, which when executed, determine a first set of design limits based on stress conditions arising from the temperature and pressure profiles from a multi-tubing drilling module and a multi -tubing production module for drilling and production operations. A multi-tubing multi-string module predicts the annular fluid expansion (AFE) and annular pressure buildup (APB) of the multi-tubing well from the previously calculated temperature profile, pressure profile, and stress conditions and determines a second set of design limits with the AFE/APB effects in addition to the temperature profile and pressure profile predicted from multi-tubing drilling module and multi-tubing production module. The first and second sets of design limits are depicted using one or
