Managing the produced water associated  with gas recovery represents a significant issue.   This book describes time-lapse crosswell seismic  experiments that were designed to monitor and  evaluate the spatial efficiency of the dewatering  process. Results from the time-lapse tomograms show  that the spatial distribution of the P-wave velocity  changes approximates 6 percent above the coal as  well as inside the coal layer. This difference can  be attributed primarily to pore fluid saturation  occasioned by the dewatering process. The observed  changes are consistent with coal physics models and  observations from production data and they  demonstrate feasibility to monitor the reservoir  production process. Results further suggest that  produced water comes from the sandy-shale directly  above the coal and that pressure drawdown in the  coal is not spatially efficient. This book shows  that time- lapse seismic can provide valuable  information for reservoir process monitoring,  optimization and management during reservoir  production process.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843379960\"\u003e\u003ch3\u003eTime-lapse Seismic Imaging of Coal Bed Methane Reservoir from the Powder River Basin,  Wyoming, USA\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843379960","offer_id":39470072266845,"sku":"9783843379960","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c43f2403-ec7c-4212-8b6f-36ee4a707500.jpg?v=1773383815","url":"https:\/\/shop.autorenwelt.de\/products\/time-lapse-seismic-imaging-of-coal-bed-methane-reservoir-von-olusoga-akintunde","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
