Sažetak
Well KAL-5, completed in the Moslavacka Gora formation of the Panonian basin in Croatia, was tested at flow rate of 2134 m3/d of gas and 0.45 m3/d of condensate and at last bottomhole pressure (BHP) of 7.5 MPa. Pre-treatment evaluation extracted a reservoir permeability in the 0.003 to 0.004 md range. The formation is extremely hot (179 oC) and thus outside the operational margins of most fracturing fluids. Following a modest hydraulic fracture treatment, the well was flowed for 21 days at a last flow rate of 55000 m3/d of gas and 18.7 m3/d of condensate at a last flowing bottom hole pressure of 6.42 MPa. This substantial increase is apparently due to a successful hydraulic fracture whose geometric features have been estimated via a post-treatment well test. This paper presents a comprehensive pre-treatment analysis of the well, its geologic setting and thermal and lithological characteristics. An outline of the stimulation design and execution is offered. Post-treatment evaluation assesses the effeciveness of the job, calculates the geometric dimensions of the fracture, and presents forecasts of future performance. Finally, the effects of the evolved gas condensate on the reduction of the apparent reservoir permeability are investigated and evaluated. A correlation between pressure, in-situ condensate saturation, and permeability is offered.
