pdf Hydraulic fracturing application of horizontal wells in areas of inefficient reservoir drilling
The well-known problem of distortion of the indications of integral geophysical methods used in the geonavigation of horizontal wells, due to large zenith angles. The problem gets even more in conditions of productive formations of low thickness, complicated by layering of various lithological composition.
When using traditional approaches to determining the efficiency of drilling based on the boundary values of porosity and saturation coefficients, significant areas of "inefficient drilling" are formed in horizontal sections of wells, in which it is not habitual to place ports for hydraulic fracturing. Meanwhile, such intervals in the horizontal part can be associated with line along a low- thickness clay screen or with its intersection by the borehole. Low-thickness clay does not make problems for creating a hydraulic fracturing crack in the productive part of the formation. In some cases, even with a significant location from the collector, it is possible to "reach" it with a crack and involve it in working.
Using the example of the Upper Jurassic formation of the Tevlin-Russkin field, the application of hydraulic fracturing in areas without collector is justified. The indicators of the operation of wells with several non-collector intervals are given, which are comparable with the indicators of the operation of wells located in similar geological conditions.

Keywords: horizontal well, hydraulic fracturing, inefficient drilling, Upper Jurassic formation of the Tevlin-Russkin field.
