Geophysical surveys are used in oil and gas exploration to best determine where hydrocarbons are likely to be located. This information is used to accurately plan locations for wells, reducing the probability of drilling dry wells and consequently the need for further drilling, minimizing the environmental impact of the oil and gas exploration.

Subsurface Mapping

The process of mapping joins the interpretation of individual wells into a bigger image of the subsurface. well logs offer a micro perspective of the reservoir, mapping takes those smaller images and interprets them into a larger picture.
 

Legacy creates structure maps to translate the orientation, dip, and tectonic history of the reservoir.  Following the structural interpretation, isopach mapping permits for volumetric calculations, sediment deposition character, and finally depositional environment interpretation.

Legacy can go into additional detail through rock character mapping. These maps allow for the improvement of existing fields, the high grading of drilling locations, and finding the best drilling location of  bigger targets.

These maps come together to describe the reservoir, enabling us to derive the calculations of the volume of the oil and gas present and the best way to extract those hydrocarbons from the ground.

Seismic Interpretation

Seismic data gives us much of the same information as well logs, subsurface mapping and petrophysics. Seismic surveys also allow for interpretation over much larger areas than single point well sources. Legacy Oil locates subsurface structures, reservoir thicknesses, and fault interpretations through seismic interpretation, further enhancing the geologic description.

Once a reservoir is being developed and produced, Legacy Oil uses a consortium of Seismic Data, and possibly reprossing, with new interpretation of the seismic images to increase the understanding of the reservoir and optimize development plans.  More efficient oil and gas extraction requires fewer wells while increasing the production of hydrocarbons.
 

Geological Modelling

Geomodelling is commonly employed for identifying natural hazards, managing natural resources and measuring geological processes with primary applications to the oil and gas industry, mining industry, and environmental impact studies.
 
To forecast the behavior of rocks under different hydrocarbon recovery situations, realistic geologic models are needed as input for reservoir simulator programs. Using geological models and reservoir simulation enables reservoir engineers to determine which recovery options offers the safest and most efficient, effective and economical development plan for a particular reservoir. 
 
Geomodeling joins the subsurface maps, well log interpretation and petrophysics into one interpretation allowing us to analyze the interpretation of numerous attributes simultaneously.  Legacy employs advanced geomodeling techniques in circumstances in which comprehensive geologic interpretation significantly enriches production.
