Fracturing Fluids and Their Application in the Republic of Croatia

Hydraulic fracturing operations are performed to enhance well performance and achieve economic success from improved production rates the ultimate reserve recovery. To these goals, fluid is pumped into at pressures that result in creation of a hydraulic fracture. Fracturing selection presents main requirement for successful fracturing. The selected should create fracture with sufficient width length proppant placement carry surface created accomplish all those demands, additives added fluids adjust their properties. This paper describes classification fluids, adjustment properties requirements selection. Furthermore, laboratory tests fluid, stimulation design steps presented paper, as few examples used Croatia case studies finally, post-frac results. total gas was increased by 43% condensate 106% wells including wellhead pressure, which allowed longer life.
