Near Field & Frontier Exploration
EM field measurements are the composite responses to the subsurface resistivity, which is a result of fluid content, lithology and rock type. Mapping of the subsurface resistivity has proven a valuable tool de-risking already identified prospects in geological models. 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. Key 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 offer to 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 clients unique geological model is done in close cooperation with the end user. Allton offers tailormade 2D and 3D acquisition solutions to fit different challenges, complexity and budgets.
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 while recording a negligible source footprint from adjacent pipelines. The vertical EM data has limited influence by pipelines. The small footprint of accurately deployed source and receivers provides non-intrusive data acquisition in environmentally sensitive areas.
