Microseismic monitoring is a key part of the characterization workflow, and is required for the proper evaluation and production of unconventional resources.
Various techniques exist for forming a picture of a fracture network, and Schlumberger has services and technologies for all of them. Downhole monitoring, for example, is performed by placing the Wireline VSI tool in an adjacent well. Surface monitoring is done with a WesternGeco UniQ integrated point-receiver land seismic system surface spread. The grid option is offered by drilling shallow monitoring wells around the planned completions.
