drilling fluids, then opened the reservoir hydraulically and
pumped the proppant. Screens keep proppant from entering the
wellbore during production. While gravel packs may be adequate,
frac packs increase well productivity.
As LLOG learns more about reservoir performance, additional development wells and exploration step-outs are anticipated.
The majority of the development work is planned for the dualBOP West Neptune. Other single-BOP rigs are planned for the
riserless portion of these wells, enabling the West Neptune to drill
the deeper portions of the wells to total depth, and then to complete with no added downtime for BOP recertification.
Future Plans

A total of seven Delta House wells are being brought on production to the FPS now, with the two additional wells drilling later this year planned in the near term. Since the original execution of the ArcLight transaction, a third-party field (not LLOGoperated) has contracted for processing at the Delta House FPS.
LLOG anticipates continued exploration in the area, ultimately
resulting in additional LLOG-operated fields tied to the FPS for
processing. Ultimately, we expect 15 wells to be produced to the
FPS.
LLOG is planning to begin engineering for the second stanRICK FOWLER has been the vice president of deepwater proj-

ects for LLOG Exploration Company since 2007. He has been
involved in multiple Gulf developments using both floating production systems and subsea tiebacks. Prior to joining LLOG,
Fowler was employed by Dominion Exploration & Production
and Exxon in various operational and supervisory assignments.
He holds a B.S. in mechanical engineering from Tulane University.
ERIC ZIMMERMAN is vice president of geology at LLOG Exploration. He joined the company in 2007 as a deepwater geologist. Zimmerman has focused his career on exploration and
development projects in the deepwater Gulf of Mexico, with previous experience at BP and Dominion. He holds a B.S. and an
M.S. in geology from Louisiana State University.
JOE M. LEIMKUHLER is vice president, drilling, at LLOG.

He joined the company in 2012 and has 31 years of experience
in onshore and offshore drilling. He began his career working
the Wyoming Overthrust Belt as a mud engineer before joining Shell, where he held a variety of roles, mainly in the deepwater Gulf. Leimkuhler holds a B.S. from the University of Montana and an M.S. in petroleum engineering from the University of Wyoming.
CRAIG MULLETT is offshore construction manager at LLOG
Exploration. He has served at the company for 16 years, join-

dardized Delta House FPS, which will be used on a future discovery. That engineering effort will include removing the crude
stabilization unit, restoring the other design basis parameters to
their original values (including oil as low as 25 degrees API gravity and ANSI 1,500 gas export with associated booster compression), and making a variety of other improvements designed primarily to save weight. LLOG also will consider pre-engineering
a water injection unit that can be installed on the FPS, once the
production performance is understood.
Delta House is truly a "fast-track" project. Key contributors
to the accelerated project schedule were concept selection, early start of engineering, yard bidding prior to first discovery, and
purchasing long-lead-time items before project sanctioning.
Project sanctioning was accelerated by private equity financing
of the infrastructure and lowering the producers' economic threshold so the project could move forward with only two LLOG wells
drilled. Implementation of the project went well.
Delta House was designed to be the first of many in a series
of similar FPS facilities. The OPTI-11000 hull design and
LLOG's standard topsides design are highly flexible and should
be suitable for many deepwater projects. LLOG expects to use
the lessons learned from executing each project to make minor
adjustments to improve subsequent projects.

ing LLOG in 1999 after an 18-year career as a facilities engineer at Shell. Mullett holds a B.S. in mechanical engineering
from the University of New Orleans.
BRUCE D. COOLEY is vice president, facilities, at LLOG.

He has 24 years of industry experience, including extensive experience in subsea and deepwater development projects. Before
joining LLOG in 2001, Cooley worked for Texaco USA and Texaco North Sea UK for 12 years, and was involved in Texaco's
first deepwater development in the Gulf of Mexico. He holds a
B.S. in mechanical engineering from the University of LouisianaLafayette.
BARNEY P. PATERNOSTRO is a completions/production engineer at LLOG Exploration. With 26 years of experience with
major and independent oil companies, he joined LLOG in 2007.
During his tenure at the company, he has implemented 16 deepwater subsea completions, 10 of which were intelligent wells
with two to three stacked frac packs. Paternostro holds a B.S.
in petroleum engineering from Louisiana State University.
JACK BOELTE is director of marketing and midstream at
LLOG. He joined the company in 1992 and has 20 years of industry experience in marketing. He has served as director of marketing and midstream for the past 10 years. Boelte received a
B.S. in accounting from Louisiana State University.
