METHOD FOR FINDING DEPOSITS OF OIL AND GAS Russian patent published in 2005 - IPC

FIELD: oil industry.

SUBSTANCE: method includes determining oil and gas availability of area on basis of presence of deep reservoirs in earth crust, by means of deep-mode seismic reconnaissance, and marking sizeable dynamic anomalies, prediction and localization of oil channels is performed, level of activity of oil channel is performed. Prediction and localization of oil channels is performed on basis of seismic reconnaissance in 2D or 3D variant. To determine activity of oil channel at territory of outlet of channel instability of gravitation field is researched by various special observations at fixed positions and determining changes of gravitation field in time at each of these. On basis of presence of areas of increased instability of gravitation field activity of channel is estimated. After determining channel activity, search well is drilled immediately at oil channel. At areas with uncertain availability of oil and gas, observations are performed in conjunction with geo-chemical filming.

EFFECT: higher efficiency.
