Underbalanced Drilling Manual and Short
Course Materials. [CD-ROM with single user license]
In
underbalanced drilling operations, the pressure of the drilling fluid in the
borehole is intentionally maintained below the formation pore fluid pressure, in
the openhole section of the well. This CD-ROM contains the full text of the
massive manual which describes the different techniques that can be used to
generate underbalanced conditions while drilling.

Summary: In
underbalanced drilling operations, the pressure of the drilling fluid in the
borehole is intentionally maintained below the formation pore fluid pressure, in
the openhole section of the well. This CD-ROM contains the full text of the
massive manual which describes the different techniques that can be used to
generate underbalanced conditions while drilling. The benefits of drilling
underbalanced, which can be considerable in terms of reduced drilling cost and
increased productivity, are discussed. Special equipment and procedures, as well
as technical and economic factors limiting the application of underbalanced
drilling, are examined. The manual addresses the selection of appropriate
technique; well engineering (with calculation examples in the appendixes); and
special considerations, such as safety, regulatory requirements, environmental
issues, and formation evaluation. The manual is also available in book format
(see GRI-97/0236). The CD-ROM also contains slides for a training course on the
subject, as well as photographs, information on the Gas Research Institute and
on the contacts for obtaining further information on GRI research.
