Owner Objective
MarkWest Energy Partners, L.P. (MarkWest) provides fully integrated natural gas midstream services in the liquids-rich areas of the Marcellus and Utica Shale. MarkWest is the largest processor of natural gas in Marcellus, with fully integrated processing, fractionation, storage, and marketing operations.
CEC Approach
Since 2010, CEC has developed a partnership with MarkWest through work on several gas processing and fractionation facilities as well as NGL pipelines in Ohio, Pennsylvania, and West Virginia. CEC and MarkWest teamed up early to evaluate potential sites for development of processing facilities and to evaluate potential pipeline routes.
CEC’s experts researched potential sites and right-of-ways (ROW) to identify stream and wetlands impacts, geologic hazards (landslide prone soils, rock outcrops, etc.), prepared preliminary layout and grading plans, completed estimates of earthwork volumes, plotted utility locations, and prepared permitting and constructability reviews to aid MarkWest in site and ROW selections. To date, CEC has collaborated with Markwest to complete engineering and permitting designs for ten MarkWest gas processing and fractionation facilities and over 600 miles of NGL and natrual gas pipelines.
