Wimborne Coal Bed Methane (CBM) Production Field & Compressor Station (2005 to 2009)

Wimborne Coal Bed Methane (CBM) Production Field & Compressor Station
  • Due to the volume of wells drilled and tied-in over the period of a year (100+ wells), an extensive effort was made to develop a standardized and simple design with repeatability for all equipment on site.
  • Due to the very low gathering system pressure, an extensive network of HDPE pipelines were installed to gather production from a large number of wells and to flow production to a central compressor station. Extensive work with Facilities, Construction, and Operations on a continual basis to improve construction cycle times was important.
  • Due to the nature of the area and landowner base, a very short construction window was permitted for pipeline and wellsite construction. Late fall and early winter were all that was available for pipeline installation due to landowner constraints not allowing construction while crops were in and limitations of working with HDPE pipe in cold conditions. A standardized and simple approach was taken to pipeline and wellsite installation. The majority of the pipelines were installed using low impact methods that expedited the construction schedule and supported good landowner relations.
  • As a result of the addition of wells, expansion of the existing compressor station was required on a yearly basis during the life of the project. While Precision did not install the original compressor station, extensive work was completed to simplify and standardize future compressor installations with the addition of the second compressor by Precision. Subsequently, Precision installed two additional 1500 hp natural gas drive compressors to accommodate increases in production due to infrastructure expansion. Portions of the pipe rack and inlet area were reworked, including catwalk and platform structures, to accommodate ease of future compressor installs. While resistance came from the client to keep costs to a minimum during the installation of the second compressor on site, the rework was permitted to go forward, with cost and time savings more than making up for the initial capital spent.
