EFFECTIVE GAS AND OIL-SATURATED HYDROCARBONS DEPOSITS QUASI-THREE-DIMENSIONAL MODELING METHOD Russian patent published in 2019 - IPC G01V1/28 G01V1/30 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the field of oil and gas industry, the well drilling data integrated interpretation and the hydrocarbon deposits geological models creation for their reserves calculation, the development design and monitoring. Proposed is the effective gas and oil-saturated hydrocarbon deposits quasi-three-dimensional modeling method. According to the claimed method, obtaining data for all wells with dedicated reservoir and non-reservoir beds, the simulated formation roof and bottom maps by the stratigraphy and the reservoirs, as well as the simulated reservoirs inter-fluid interfaces maps. Next, in the wells recalculating defined by the well log interpretation results the reservoirs and non-reservoirs individual layers roof and the bottom absolute elevations into the normalized paleodepths. By the collectors recalculating the reservoir roof and the bottom maps, as well as the inter-fluid interfaces maps into the normalized paleodepths. Creating the net-to-gross sand ratio maps are for the reservoir to be simulated gas and oil saturated portions. At the last stage, calculating the effective gas and/or oil-saturated thicknesses maps are by the formation total gas and/or oil-saturated maps thicknesses multiplying by developed at the previous stage the net-to-gross sand ratio maps.

EFFECT: increase in the oil and gas fields exploration and development efficiency through the use of the available geological and geophysical information more complete array and, as a result, obtaining more geologically sound results, similar to the three-dimensional modeling results, in significantly less (compared to the latter) time.
