Near Field & Frontier Exploration
EM field measurements are the composite responses to the subsurface resistivity, which is a result of differences between fluid content, lithology and rock type. Mapping of the subsurface resistivity has proven to be a valuable tool in de-risking already identified prospects. To exploit the advantages of the EM technology, Allton works closely with exploration teams to increase the geological understanding of an area to address prospect specific challenges. A key Allton advantage is the proximity of sources and receivers giving the ability to utilize short-offset high sensitivity measurements for accurate mapping of geological features. The integration of Allton`s EM-data with other geologic, petrophysical and rock property data can often provide key support in the risking process.
Allton will manage all phases of a project in cooperation with the client starting with initial sensitivity evaluations and survey design through acquisition and inversion. Incorporation of the EM data in each client’s unique geological model is done in close cooperation with the end user. Allton offers tailormade 2D and 3D acquisition solutions to fit different area challenges, geologic complexity and budget considerations.
The source and receiver systems are stationary during data recording and survey parameters can be tailored to generate higher signal to noise ratio data to meet specific exploration requirements. This stationary acquisition mode is also well suited for near field exploration close to existing infrastructure as it records a negligible source footprint from adjacent pipelines. Vertical EM measurements have limited influence in the data response induced by horizontal infield infrastructure. The small footprint of accurately deployed source and receivers provides non-intrusive data acquisition in environmentally sensitive areas.
The 6507/8-10S well is dry and “No traces of Petroleum were proven” said the Norwegian Petroleum Directorate.
