Key findings of the comprehensive interpretation

Paleozoic formations are represented by an array of weakly dislocated carbonaceous rocks. Dislocations pozdnegertsinskogo orogeny and subsequent tectonic movements have contributed to the development of organogenic limestone zones of fracturing, dolomitization, caving.

Carbonate and terrigenous-carbonate rocks are altered supergene processes that led to the formation of cavernous rocks and weathering crusts.

hydrocarbon deposits are massive, associated with organogenic limestones and dolomites as well as the weathering crust, represented bauxite. Not appropriate identification of deposits from the producing formation of layered structures.

According to the complex geological and geophysical interpretation and Urmanskoye Archinskoye uplift is composed primarily of rocks with well-developed secondary porosity, with poorly predictable changes in reservoir properties.

At this stage of geologic deposits of the main criterion for identification of hydrocarbon traps (in conjunction with the prediction of lithology) is a structural factor.

Calculation of reserves and resources

 

Stocks categoryC1 counted on the results of exploration and development drilling and should be explored to the extent that ensures receipt of initial data for flowsheet development oil or project pilot gas field development.

Category C2 reserves of a deposit (part), which can be justified by the data of geological and geophysical studies:

- in the unexplored parts of the reservoir adjacent to areas with more than high categories;

- in the intermediate and vyshezalegayuschih untested reservoirs discovered fields.

C3 - advanced oil and gas resources prepared for deep drilling areas located within the oil and gas area delineated and tested methods for the area of ​​geological and geophysical studies and drilling are not exposed seams explored deposits if their productivity is set to other fields of the area .
