Satellite, aerial and other images showing energy development in the Upper Green River Valley of western Wyoming (featuring the Jonah and Pinedale Anticline natural gas fields). UPDATE 3/21/06: Today the Bureau of Land Management approved a plan promoted by a Canadian company and other field operators to drill an additional 3,100 wells in the Jonah Field, an order of magnitude increase over the 700 wells currently installed. In places the well spacing will be as close as one well every 5 acres (currently the density is one well every 40 acres, or 16 per square mile). The BLM will allow up to 46% of the acreage within the field area to be disturbed (unreclaimed) at any given time. Directional drilling is not being required, and all of the additional wells could be drilled vertically from new well pads. The ability to restore sagebrush and other native vegetation in this area has not been demonstrated. UPDATE 11/16/05: New images of the Jonah and Pinedale Anticline fields have been added to the time series, from a Landsat TM image (30 meter detail) taken on August 31, 2005. The Pinedale and Jonah fields have expanded to where they have now effectively merged. UPDATE 2/17/06: Added an oblique aerial photo showing current winter drilling experiment in Jonah field, using portable wooden mats to create a wellpad instead of bulldozing. Well locations here are at 5 to 10-acre spacing, which will occur over much of the 30,000 acre Jonah Field if 3100 new wells are approved by BLM. UPDATE 4/18/08: The time-series for Jonah and Pinedale fields have been extended by adding satellite images from 2006 and 2007. Google Earth users: download a KMZ file for Jonah to explore a 1-meter-resolution satellite image of the area that was taken on August 15, 2006 (http://skytruth.mediatools.org/objects/view.acs?object_id=11855).
