Performing drilling works and geological and hydrogeological surveys related to the execution of the hole Gąsawa GT-1. The task of the hole is to recognize and document the operating resources of the geothermal aquifer level of the lower jury and to recognize the hydrogeothermal conditions of the reservoir Lower Cretaceous in Gąsawa. The well is targeted to act as a mining hole. The task provides for priority recognition and recognition of the waters of the Lower Jurassic aquifer. However, the recognition of the lower Cretaceous geothermal level was also provided, with its alternative aflirting, in the case of weak hydrogeological parameters of a deeper aquifer level. The solution of the geological task is designed in one stage including the execution of the Gąsawa GT-1 drill hole with a depth of 3600m± 10% and carrying out the necessary tests to identify and document the operational properties of the lower chalk aquifer level and lower jury.
The object of the order is the execution of the geothermal hole Gąsawa GT-1 on the plot number 2, within Gąsawa. In the field of execution are geological and mining works involving the execution of a research and operation hole together with all necessary work and measurements necessary for its execution and provided for it. Drilling of the hole will be carried out in accordance with geological and technical drilling projects drawn up by the Contractor, on the basis of an approved Geological Works Project for the execution of the Gąsawa GT-1 test hole for the recognition of thermal water deposits resources and determination the possibility of their use, provided by the Ordering Party.
It is assumed to make a test and operational hole, which will be included in the lower jury works in the interval depth 3430-3570 m p.p.t. as the actual depth criterion, the need to drill up to 30 m of upper Triassic tracks (under the subfilter column). The solutions also take into account the need to recognize (and optional shot) of a lower Cretaceous geothermal reservoir. The drilled aquifers will be hydraulically isolated by cementation of cladding pipes. The filter column of the hole Gąsawa GT-1 will be made using corrosion-resistant materials. For the entire length of the drilled hole, the maximum angle of deviation from the vertical axis up to 3° is allowed, with the maximum spatial curvature angle increment (DLS) not exceeding 1°/30m. During drilling, pointwise measurements of the angle of deviation and azimuth with a slot machine inclinometer, every 100 m and before each pulling of the conductor. In order to measure azimuth, a non-magnetic sinker must be placed in the set of the drilling conductor.
The location of the hole should be defined geodesic in the field, in accordance with the approved Geological Works Project. After delineation and after completion of the hole, a geodetic operat must be drawn up and the coordinates in the applicable State Coordinate System shall be determined.
