Beyond Increased Drilling
Efficiency, Does Managed Pressure Drilling Improve Safety in Deepwater
Operations?
Moderator: Mark Mitchell, VP Drilling Optimization Services,
Weatherford International, Inc.
Over the
past few years MPD has been applied throughout the world with great
success. These success stories were first being heard from land operations,
but quickly moved offshore onto jack-up and platform installations
conquering some of the most difficult drilling challenges facing the
industry. In the past couple of years, MPD techniques and technologies have
migrated further offshore and been used on floating rigs in deeper water
with similar success stories. Like their land and platform predecessors,
the wells drilled from floating rigs have not only achieved operational
efficiencies not possible with conventional drilling methods, but have also
increased the safety of the operations by the increased ability to identify
and mitigate or minimize downhole events that would have posed high levels
of risk for rig operations not utilizing MPD techniques.
High-risk areas such as the North Sea and less developed
areas such as Southeast Asia are beginning to recognize the benefits of MPD
techniques. Offshore West Africa and the Mediterranean off the coast of
North Africa are following suit and tackling their difficult prospects using
MPD. Latin American countries from Mexico to Brazil are realizing that they
cannot reach their deepwater target reserves cost-effectively or safely with
conventional drilling techniques and are exploring the application of MPD. By comparison, some geographical areas have only dabbled in MPD techniques
and technologies.
This panel session will bring together a variety of global
operators and regulators who have used, or have investigated using, MPD
technologies and to try to identify the drivers of why MPD has seen more
application in some regions of the world compared to others. Are the
drivers for MPD based on benefits to operational efficiency, safety or
both?

Intelligent Control System for Precise and User Friendly Pressure Regulation
in MPD Operations:
Alexey Pavlov, Senior Researcher, Statoil ASA
To achieve
faster and more accurate regulation of the annulus pressure, an intelligent
control system has been developed and tested in Statoil. It is based on an
accurate yet simple model of the wellbore hydraulics. By processing
additional measurements and the model, the control system provides faster,
more accurate and robust control of the choke pressure. In experimental
results from full-scale tests on Ullrigg - an experimental drilling rig in
Stavanger, Norway, the control system has demonstrated better performance
than conventionally used choke pressure controllers. Moreover, it appeared
to be very predictable and user-friendly.

Drilling an
HPHT well using MPD technique leads to complex planning especially when
limited by narrow mud window and equipment specification rating. An
economical aspect driven by timing for project finalization schedule also
determined the success factor for the project. A sidetrack drilling
operation with specific procedures were made to overcome well control issues
which has happened in the original 8-1/2" hole section. The
well testing results
show a significant reduction in the skin damage predicted by the subsurface
team. The case history of planning and execution of the project will be
explained.

Offshore
Underbalanced Drilling With a Closed-Loop Circulating System:
Geoff Gough, Senior Process Engineer, S. Talbot, H. Moss, DONG Energy (IADC/SPE 143096)
A review of
an offshore underbalanced drilling project in the Danish sector of the North
Sea, undertaken during the summer of 2010 will be presented. Two oil wells
were drilled from a jack-up drilling rig, with produced oil and gas
transferred to the accompanying production platform. A closed-loop
circulating system was employed, completely bypassing the rig’s pits and
shakers.

Pumped
Riser, MPD Method for Offshore Floating Drilling Units:
John Cohen, R&D Technology Manager, AGR Drilling Services
Pumped Riser
is an MPD method specially designed for floating drilling units. The pumped
riser method offers the following advantages; 1. Viable for low and high mud
weight environments 2. Provides automated “near constant pressure” at depth
of interest 3. Does not require a rotating control head incorporated into
the riser 4. Does not require the use of a lower density (below pore
pressure) fluid 5. Does not require circulating well to higher density fluid
for tripping 6. Does not require special well control provisions to
circulate out kicks.
Well
Control When Drilling With a Partly-Evacuated Marine Drilling Riser:
Kristin Falk, Senior Manager MPD Control Systems, B. Fossli, C. Lagerberg, Ocean Riser Systems,
A. Handal, S. Sangesland, Norwegian University of Science & Technology
(IADC/SPE 143095)
This paper shows how the Low Riser Return System reacts to an influx.
Whereas with a full riser, an influx pushes mud out of the top of the riser;
this volume will be contained in a partially evacuated riser, increasing the
level and the bottom hole pressure. The system will also greatly improve
kick detection and hence reducing kick size. This technology can greatly
improve safety in drilling of deepwater exploration and production wells and
infill drilling in depleted fields, enabling safe access to more reserves,
improving recovery factors.
Dual
Gradient Drilling Moves One Step Closer to Reality:
John Cohen, R&D Technology Manager, AGR Drilling Services
A method
that uses the subsea pumps of a Riserless Drilling System has been developed
thus allowing Dual Gradient Drilling of subsea wells after installation of
the riser and BOP. Dual gradient well control procedures have been
developed. Using Dual Gradient Technology will allow certain tight tolerance
intermediate casings to be eliminated whilst maintaining full riser margin
and trip margin. The Dual Gradient System provides added safety by providing
more sensitivity in gain/loss detection and diverting mud flow and
hydrocarbon influxes away from the drilling riser to surface via a mud
return line with choke.

Petrobras
Petrobras’
major interest in MPD technology is to use the system as a security enhancer
and reduce non productive time due to well control situations. Even though
the targeted scenario is deep and ultra-deepwater operations, a Technical
Cooperation Agreement with Impact Group was established to perform a four
well evaluation program of the Microflux control MPD, from a simple land
well operation progressing to a more complex scenario in a tight-gas jack-up
rig operation. The experiences achieved so far and the actions to implement
MPD technology in dynamic positioning drilling units targeting deep and
ultra-deep waters operations will be reported.
Managing
ECD and Determining Pore Pressure With MPD Improves Drilling Efficiency in
GOM Well:
Paul Fredericks, Director of Marketing, At Balance, A Schlumberger Company
Stone Energy
successfully drilled a recent well in the Amberjack field using managed
pressure drilling techniques that were unavailable 9 years ago. They
encountered none of the stuck pipe, lost circulation, wellbore instability,
and other unplanned well control incidents of past wells last drilled in
2001 and were able to save 15.5 drilling days compared to the two previous
offset wells. In the 17 drill pipe connections that were made, the
automated MPD system accounted for only 6.5 minutes of the total connection
time for pressure control.
Kick Detection and Well Control in a Closed Wellbore:
David Pavel, Director Business Development, Weatherford (IADC/SPE 143099)
How do we deal with kicks in Managed pressure drilling operations? At what

RCDs – Are
They a Safe and Dependable Well Control Barrier? An Operator’s View:
Dave Elliott, UBD/MPD Principal Technical Expert, Shell International E&P
Shell has
been working with major RCD equipment suppliers to apply practices, similar
to those that are used to certify BOP equipment, to re-define what are the
safe operating envelopes for their equipment. In many cases testing over
and above API 16 RCD is being used to prove that equipment is
“fit-for-purpose”. This paper will review the history that has resulted in
Shell’s view that current RCD testing does not adequately support using an
RCD for a well control barrier. It will also summarize what is being done
to upgrade the industry’s RCD testing focus from product optimization to
product certification.
Alternative Shut-In and Pump Start-Up Procedures for Kicks Taken During MPD
Operations:
John Rogers Smith, SPE, Associate Professor,
J. E. Chirinos, SPE,
D.A. Burgoyne,
SPE,
Louisiana State University (IADC/SPE 143094)
The basic
concepts of CBHP method of MPD will be explained with a detailed description
of the full scale experiment setup. Subsequently, full scale experiments
will be used to demonstrate the procedures and calculations used for simple
shut in, MPD pump shut down with a choked flow check, pump start up and kick
circulation. The results will be compared to computer simulations to verify
the validity of the simulator for studying these procedures. A summary of
these procedures and conclusions regarding their application and
effectiveness will be presented.

Results of
the implementation of a phenomenological two phase flow model aiming the
development of a classic PI (proportional - Integral) controller for
bottomhole pressure during a drilling job will be shown. Additionally, the
presentation highlights different alternative control strategies, of common
use in different industrial applications, which can help in the development
of automatic control in different phases of a drilling operation.
A Proposed
Method for Planning the Best Initial Response to Kicks Taken During Managed Pressure Drilling
Operations:
John Rogers Smith, SPE, Associate Professor, Louisiana State
University, B.M. Patel, Weatherford (IADC/SPE 143101)
Review of
the different possible alternative responses to kicks taken during MPD and
the main advantages and disadvantages of each. The initial response decision
tree and its three primary response types: continue drilling, shut in, and
circulating responses to increase bottom hole pressure will be described. An
example application of the decision tree will be presented and compared to
simulation results. Finally, a graphical method to quantify the advantage of
using a circulating response in combination with sensitive flow out metering
to provide a larger kick tolerance than a shut in response provides will be
shown.

Intelligent Estimation of Downhole Pressure Using a Simple Hydraulic
Model:
Glenn-Ole Kaasa, Principal Researcher, Statoil, O.N. Stamnes, L. Imsland, O.M. Aamo,
Norwegian University of Science & Technology (IADC/SPE 143097)
The
hydraulic model is an essential part an automated MPD control system, and is
in most cases the limiting factor for achievable accuracy. We present a
simplified model based on basic fluid dynamics, and demonstrate that it
captures the important hydraulics of an MPD system. Furthermore, we
demonstrate that by applying advanced algorithms for online parameter
estimation, the model can be calibrated automatically, achieving a level of
accuracy similar to that of advanced hydraulic models. The results are
demonstrated on field data from MPD operations and experiments obtained in a
full-scale drilling rig.
New Technology Which Enables Closed, Looped Drilling (MPD)
from Mobil Offshore Drilling Units (MODU):
Jan Atle Andresen, Business Development Manager, Siem WIS AS
Siem WIS has
developed new technology within MPD since 2006. The new patented sealing
technology (no bearings) enables MPD from floaters. By utilizing the PCD for
platform/Jack up, land drilling and the RPCD for MODU`s the patented
gradient system is monitored constantly and gives full status of the seals
at all times. This gives a safer and controllable drilling when utilizing
MPD technology.

MPD
Complements Drilling Engineering Program to Mitigate Risk and Reduce NPT in
a South Louisiana Gas Field:
Jean-Paul Michel, Drilling
Engineer, Forest Oil Corporation, Jason Duhe, At Balance, A Schlumberger Company, Larry Smith, Consultant
In their
effort to avoid the drilling problems encountered in past wells in the West
White Lake Field in southern Louisiana Forest Oil developed a detailed
drilling engineering program that included a lower static mud weight to
avoid losses and ballooning and an automated MPD system to hold the BHP near
constant below fracture pressure to avoid instability and stuck pipe, and
reduce connection gas, surge, and swab. Forest Oil was able to drill the 6”
production interval in 100 hours with a single BHP, reduced NPT and
connection gas, and no stuck pipe, losses, ballooning, or kicks.

The Burgos
basin is one of 4 major gas basins in Mexico. It is located on the
north-western side of the Gulf of Mexico in the state of Tamaulipas and
Nuevo Leon covering an area of 50,000 km2. The basin was discovered in 1945
and is still a major contributor to the gas production in Mexico. The use of
the Managed Pressure Drilling (MPD) technique in North Mexico has brought
important improvements to the drilling operation; non-productive time, mud
losses and kick events have been reduced achieving important savings.

P. Vieira, Weatherford Oil Tool Middle East Ltd., A. Rai, B. Vudathur,
Reliance Industries (IADC/SPE 143102)
Managed
Pressure Drilling is defined as a drilling technology that uses specialized
equipment to more precisely control the wellbore pressure profile. The
application of this technology will optimize the drilling process by
decreasing Non Productive Time (NPT) and mitigating drilling hazards
associated with conventional drilling techniques. This presentation shows
the work performed in the planning phase and the operational results of the
application on Managed Pressure drilling technique for drilling an
exploratory well on semi-submersible rig in India.

Fluid Design Enlarges the Hydraulic Operating Windows of Managed Pressure
Drilling Operations:
Mike Rafferty, Manager Engineering Services, MI-SWACO (IADC/SPE 139623)
A
description of how aspects of drilling fluid design and properties can
enlarge the hydraulic operating window of MPD operations, by reducing the
back pressure at connections, break circulation pressures, swab and surge
pressures. Case histories from the North Sea and Gulf of Mexico are
described that show how low rheology drilling fluid systems reduce
frictional pressures by 50%, yet annular flow rates are increased by between
15 and 25%, while pump pressures are decreased by 6%. Through the improved
management of downhole pressures, the risk of wellbore instability events
during MPD operations is reduced.

Specifically
in the Mediterranean Sea, with recently identified resources at depths of
6,000 – 7,000 meters, with bottom hole temperature near 400ºF and formation
pressure that could reach 22,000 psi (clearly an HPHT condition),
impossible to be reachable with conventional drilling practices without facing
considerable risks, incur in extremely high non productive time accumulated
and related high operating costs, the use of MPD is establishing the new
standards for drilling wells in the area due to the important success
obtained.
