Note: This virtual workshop is available for free to paid attendees of the Geothermal Resource Council’s Annual Meeting and Expo.  Register for the full conference on their website.

This workshop will provide attendees with an overview of wellbore tubular deformation modes which occur in geothermal wells that affect wellbore integrity and access. Various geothermal wellbore applications, commonly located in highly faulted and tectonically active regions, will be reviewed.

An overview of deformation mechanisms, including buckles and shears arising from formation movements (i.e. depletion-induced subsidence), trapped annular pressure collapse, and parting of tubulars will be explored with associated impacts on well integrity. Logging and intervention methods used to detect and characterize the location, magnitude and nature of the deformations will be examined, with an emphasis on multifinger caliper (MFC) logging methods.

Deformation case histories using the MFC analysis software program Well Xplore™ will be presented as well as how information obtained from such analyses can be used to assess well integrity, access risks and guide well design and well life.
