The total depth of Shyrak 1 well, established based on the results of the performed logs, i.e. 6,597.1 m, was reached. Further deepening of the well is not planned and a possible slight change of the depth may be connected with works which will be carried out in order to prepare the well for casing a 7-inch diameter column.
On the basis of the interpretation results of performed logs, initially, 19 hydrocarbon-saturated horizons with the total thickness of 464 metres were selected for testing. The thickness of individual horizons ranges from 10 to 45 metres.

All reservoir horizons selected to be tested coincide with the zones during the drilling of which high gas readings in the drilling mud or gas flow to the well were observed.
In the nearest future, the casing and cementing of a 7-inch diameter column will take place. Subsequently, the plan is to replace the Saipem rig with rig which is smaller and at the same time cheaper in use, which will serve to test the well.

The interpretation results of performed logs confirm the hydrocarbon saturation of the entire profile of sub-salt rocks that was observed during the drilling. The porosity of reservoir rocks reaches 12% which should be considered a high value, considering that the rocks are located at a great depth. Moreover, on the basis of the interpretation of the log results it was not determined that the reservoir rocks, besides the hydrocarbons, were saturated with movable reservoir water. This fact is of positive significance both for the well testing process and the production of hydrocarbons from the field. It should also be noted that the reservoir properties of rocks and their saturation estimated on the basis of log results are congruent with the results obtained in the lab during the examination of the collected cores.

The logs confirmed that the permeability of reservoir rocks and the gas shows found during the drilling are closely connected with fractures. Both the observed density of fractures and the fact that most fractures are open make the occurrence of a flow of hydrocarbons during testing very likely. The size of the flow as well as the type of hydrocarbons will be determined based on the well testing results. Based on the composition of the gas obtained during the drilling, researchers plan to determine a flow of gas and gas with condensate.
