Notional Field Development Final Report - EBN

EBN Notional Field Development Plan
As a development area is built-out, the network of gathering lines can become extensive and it is
important to plan for future field development in relation to route selection and proper sizing of these
gathering pipelines.
As discussed on the section on roadways, there is a requirement to perform the appropriate preconstruction
field studies to determine if the linear route of these pipelines will have any type of
environmental impacts upon areas such as wetlands, stream or river crossings, threatened &
endangered species, archaeological sites and flora and fauna / biological media. These field studies and
the associated permitting process and timelines can have an impact upon a project from cost and
scheduling perspective. In many instances, mitigation plans with offset requirements will need to be
developed and implemented.
4.6.4 Processing Facilities
Gas processing facilities are designed to remove impurities from the gas stream to bring it up to
“pipeline spec” so that it can be sold into the marketplace. Because the geochemical composition of the
host formation for the shale gas varies, the list of “impurities” that need to be removed will also vary
depending upon the source of shale gas and each processing facility needs to be designed to treat the
relevant constituents. These units are designed to remove water, CO 2, H 2 S, and fractionate (separate)
liquid and vapor products to meet pipeline specifications.
