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: 

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.

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.
