A joint Shell/Neos Geosolutions presentation at the US Groundwater Protection Council’s recent forum on stray gas incidence and response described the use of remote sensing technologies to detect surface and near-surface stray gas occurrence and migration pathways.
The presentation described the joint ‘Neoprospector’ in north-eastern Pennsylvania. Last year Shell contracted with Neos to conduct a remote sensing survey of its Tioga County acreage with the aim of detecting hydrocarbon seeps and surface indicators and identifying ‘orphaned’ wellbores that were no longer documented in state, county, or prior leaseholder records.
The non-seismic survey involved resistivity mapping and hyperspectral imaging of geo-hazards and floral surface variations. The airborne EM resistivity dataset was integrated with other newly acquired potential field datasets along with well, seismic, and production data, and used to geostatistically characterize production sweet spots in the Marcellus shale. Neos investors include a certain Bill Gates! More from a ‘narrated slideshow’ here.
