Project Number 27
Date of Summary December 31, 1980
Subject Technology Assessment for Cementing Shallow Casings
Performing Activity Maurer Engineering
Principal Investigator Dr. William J. McDonald
Contracting Agency Bartlesville Energy Technology Center
Estimated Completion Complete
Description A study of the cementing practices applied to shallow casings in offshore wells. Survey information shows that annular gas flow associated with cementing defects is a major problem in shallow casing strings offshore as well as in other cemented strings in oil and gas wells. The gas flow hazard to safety, environment, and economics could be reduced by an aggressive program keyed to prevent gas migration. The program components are:

1) historical database,

2) training,

3) research of cement hydration in a long thin column, and

4) development of logging-surveillance devices.
