Cement Evaluation and Repair Workshop
DISCIPLINE: Engineering
COURSE LENGTH: 1 Day
CEUS: 0.8
AVAILABILITY: Public & In-House
Check back in periodically for updated course dates!
WHO SHOULD ATTEND? Drilling and completion engineers, field supervisors, petroleum engineers and geologists, company executives and officials, independent producers, field personnel with operating & service companies, production managers and engineers.
COURSE DESCRIPTION:
This one-day training course will introduce methods of detecting fluid channels, voids, and leaks, and focus on their effective repair. Poor cement coverage often produces undesired fluids, disposal problems, reservoir pressure decline, loss of hydrocarbon reserves, and other problems. Intend to evaluate and discuss various technologies used to repair leak paths due to wellbore aging which can develop allowing fluid to migrate from the higher-pressure downhole strata through leakage paths in the cement containment.
Topics on the technologies available to repair the primary cement to the proper stage of hydraulic isolation or solve the SCP and SCVF problem will be discussed at the Training Course. Half the morning of the Training Course is dedicated to cement evaluation and the afternoon to cement repair.
