PETROLEUM EXPLORATION
We offer gravity and magnetotelluric method surveys to identify structures perspective for hydrocarbons exploration. Joint gravity and magnetotelluric surveys are recommended as reconnaissance or supplementary techniques for seismic surveys for hydrocarbons. Joint surveys increase the efficiency of geophysical investigation especially in the areas of complicated geological structure or when the seismic recognition is insufficient.
Offered integrated interpretation of gravity/MT and seismic data we propose to evaluate hydrocarbon structures and point drilling and exploratory wells. Integration of the gravity, MT and magnetic data with seismic records significantly increases the results of seismic data processing and interpretation.
IN OUR OFFER
reconnaissance surveys in the areas newly opened for hydrocarbon exploration
detailed gravity & MT recognition to point out perspective structures
tracing reservoir & source rock formations
integrated interpretation to evaluate hydrocarbon structures
drilling sites location
SURVEY METHODS
MT magnetotelluric method uses measurements of natural, variable electromagnetic field on Earth’s surface to determine electric resistivity distribution in the rock formations. Reservoir rocks being oil and gas collectors have higher resistivity (lower conductivity) than neighboring formations.
Application of gravity method to oil and gas prospecting consists in location and recognition of geological structures that can be hydrocarbons traps. Gravity method detects and measures variations in the Earth’s gravity field. Variations are associated with the changes of rock density. Some geological structures causes anomalies (disturbances) in normal density distribution. Application of gravity method consists in calculation of gravity anomalies; that brings the idea on depth and size of the bodies causing these anomalies.
