Described below are some noteworthy projects on which we are
presently engaged or which we recently completed.
Subsurface
Hard Rock Storage Caverns, Singapore
PB has been selected to perform final design
engineering for five hard rock caverns to be constructed on Jurong
Island for the Government of Singapore. Construction of this world-class
facility is scheduled to commence in early 2010 and will continue
through 2015. |
Hydrogen Storage Cavern, Texas
PB is in the process of developing a 4.5 bcf salt
cavern for storage of high pressure hydrogen. Drilling will be completed
in late summer 2009 at which time our O&M group will begin leaching the
cavern. |
Grass Roots Gas Storage Facility, UK
PB has been selected to perform subsurface Front
End Engineering Design (FEED) for a grass roots natural gas storage
facility in the UK. When the first phase is completed in 2011, the
facility will have a working storage capacity in excess of 40 Bcf. |
Acid Gas Storage Caverns, Confidential Location
In conjunction with the plans of a major energy
company to permanently sequester a mixture of CO2 and H2S
in a deep saline aquifer, PB has been tasked to develop basic designs
for a salt cavern facility for surge storage of the acid gas mixture.
|
Hard Rock Storage Cavern, West Virginia
PB broke ground for a 1.2MM Bbl, mined LPG storage
cavern in 2006 with the drilling of an 8-ft diameter service shaft and
two 3-ft diameter ventilation/pump shafts. When completed in 2011, this
will be the first hard rock cavern constructed in the US since 1984.
Prior to that time, PB constructed nearly all of the 85 US hard rock
storage caverns. |
Gas Storage Prefeasibility Studies, India
PB recently completed work for the Government of India
to assess the preliminary feasibility of developing strategic natural
gas storage stocks a several locations throughout the country. Candidate
storage locations include depleted production reservoirs, aquifers and
prospective salt caverns. During the next phase of this project, PB will
develop and oversee site investigation programs for the most promising
sites. |
LPG Storage Wells, Texas
PB recently completed drilling of two
additional large diameter salt dome wells for a commercial operator at Mont
Belvieu, Texas. The wells will be used for simultaneous commercial
brine production and LPG storage operations, and ultimately converted to
natural gas storage service. Located east of Houston,
Mont Belvieu is the world's most active cavern storage complex, hosting
more than 130 caverns. |
Mined Storage Caverns, Peoples Republic of China
In 2003 - 2004, PB prepared front end engineering designs (FEED) for two
200,000 cubic meter (1.25 million barrel) LPG storage caverns in
southern China. PB provided Owner's
Engineer and construction inspection and support
services to the project. The first cavern was placed
into service in January, 2007 and the second in the fall of 2007.
The project was constructed at BP's Zhuhai LPG Import
Terminal in Guang Dong Province.
|
Mined Storage Caverns, Japan
PB has provided consulting services to the Kajima Corporation since
1976 for the development of the Japanese Strategic Storage Program for
LPG's. The program is under construction and PB will provide consulting
services until completion in 2010.
|
Natural Gas Storage Caverns, Peoples Republic of China
PB recently completed evaluating the technical and
economic feasibility of using the Jintan salt deposits for underground
gas storage. The scope of work included developing key elements for
project planning and evaluation:
- Site evaluation and selection
- Salt cavern design
- Solution mining plan
- Operation, optimization, and management strategy
|
- Gas storage infrastructure design
- Environmental protection methods evaluation
- Economic assessment

Large Diameter Well Workovers, Louisiana
Our Field Services Division has completed the third group of
storage wells in a multi-year program to workover all wells for LOOP, LLC. Each LOOP cavern features five 30-inch
wells, four of which are equipped with 20" (or 22") suspended
casings for brine flow. Work under this program includes removal and replacement of suspended
casings and inspection and
lining of the 30" cemented casings.
Loop's caverns were developed in the late '70's by PB's Fenix and
Scisson division. |
Subsidence Monitoring
PB and affiliates developed plans and performs subsidence monitoring
for the majority of Texas and Louisiana storage facilities that are
required by regulators to monitor subsidence. |
Permitting
Situated at the world's largest underground storage complex, caverns
at Mont Belvieu, Texas are subject to special regulatory requirements.
PB developed or assisted in the development of the successful Rule 95
re-permitting packages for all Mont Belvieu operators. |

Surface Facilities
Storage Cavern Fire Protection, Texas
Texas regulations require that all natural gas
storage facilities soon be equipped with fire fighting systems. PB has
been engaged to design and construct firefighting systems for a gas
storage cavern facility in south Texas. Construction is scheduled for
completion in 2009. |
Leach Plant Rehabilitation, Texas
In order to enlarge an existing gas storage
cavern, and to develop additional caverns for a leading storage facility
operator at Spindletop dome, PB recently completed rehabilitation of an
existing 3000 gpm leach plant and drilling of an additional brine
disposal well. The facilities were commissioned in early 2009. |
Hydrogen Cavern, Texas
PB recently prepared preliminary designs
and prepare permit application documentation for a Texas hydrogen
cavern. |
LPG Handling Facilities, West Virginia
PB is performing detailed design engineering for
topsides LPG handling systems and connecting pipelines in conjunction
with the ongoing construction of it's West Virginia mined cavern
project. |
Technical Support Services, Texas and Louisiana SPR Facilities
Since 1977, PB has provided continuous technical support services for surface and
subsurface facilities to the US
Department of Energy's Strategic Petroleum Reserve Program. Among other
tasks, PB is
presently working on plans to expand the SPR capacity from 700 million
to 1 billion barrels, among other assignments. |
Pipeline Mapping, Texas
IN 2002, PB prepared detailed maps of all plant and cross-country
pipelines for the operators of storage facilities at the world's largest
underground storage complex in Mont Belvieu,
Texas. PB continues to prepare annual updates
to the drawing set to incorporate
recent construction and
piping modifications. |
