Because the applications are virtually never the same, Managed Pressure
Drilling was specifically created to give it an identity apart from
Conventional Drilling and apart from Underbalanced Drilling. Methodologies
between Conventional-Overbalanced, Underbalanced, and MPD Operations with
respect to objectives, planning, drilling equipment and operations, and well
control will be presented.
Managed‑Pressure Drilling Resolves Pressure Depletion-Related Problems in
the Development of the High-Pressure High-Temperature Kristin Field

Henry Pinkstone,Halliburton, Sperry Drilling Services (SPE/IADC 113672)
The need to implement managed pressure drilling (MPD) techniques in the
Kristin field to overcome the problems related to a narrow drilling window
is proven in this presentation. This plan would extend the life of the
reservoir since it would increase the degree of depletion up to the point
where MPD would be implemented.

Pressure (BHP) in Aerated Drilling Matches in the Field and Improves
Drilling Performance in Carbonate Reservoir
Farid Shirkavand, Geir Hareland, University of Calgary, Mohammad Haeri
Behbahani, ICOFC Co. (SPE/IADC 113686)
The conclusion that the planned UBD pre-simulated BHP match the operational
BHP will be showed during this presentation.The well drilling design of mud
and air rates and the corresponding pressures are in this paper matched
against the field recorded pressures for different mud and air rates.The
design method presented herein also proves that the best mud loss
controlling method is injecting air into mud during drilling of the lost
circulation intervals.

Applying Underbalanced Drilling Technology Improves Productivity and
Enhances Recovery in Libya
Hani Qutob, Weatherford International, A.M. Gaaim, National Oil
Corporation Libya (SPE/IADC 114052)
As of today, a total of five wells have been drilled underbalanced in Libya.
Through five examples, the paper will demonstrate that the key to selecting
appropriate Reservoir candidates for UBD is achieving a balance of Technical,
Safety and Economic factors. There have been four cases in which UBD has
been particularly successful in providing added value to oil companies in
Libya. Unfortunately, there has also been one case where UBD has been less
successful.

Underbalanced‑Drilling Techniques
Clayton
Mykytiw,
D.R. Killip,
R.W. Brewin, FX Solutions Group, John Capps, Margham Dubai Establishment
(SPE/IADC 113684)
The Margham Dubai Establishment asset is a mature gas-condensate field that
was put on production in the early 80’s. Due to rapidly declining production
of the field and Dubai’s ever-increasing domestic energy demands, Margham
initiated a drastic field intervention campaign prior to June 1, 2006.
Preliminary feasibility studies concluded that the only practical option of
increasing drainage capacity was to re-enter exiting wells drilling high
deviation multi-laterals with CTUBD techniques. The CTUBD intervention
campaign, as a mature field rejuvenation technique, proved to be a great
technical and economic achievement.
