Stimulation Technologies for Deep Well Completions DE-FC26-02NT41663 4. Case History of Hydraulic Fracturing in Jennings Ranch Field, TX Multiple Hydraulic Fractures vs. Tortuosity Figure 49. Illustration of fracture complexity: near-wellbore versus far-field The following section details all the individual fracture treatments with graphs of treatment data, fracture closure analysis, net pressure matches and resulting fracture geometry along with the production analysis plots. 4.2.3 Jennings Ranch C-10 The C-10 treatment was the only treatment where the mini-frac reached closure pressure. It was estimated to be about 0.87 psi/ft (Figure 51). Figure 52 shows that near-wellbore tortuosity and perforation friction are fairly low (190 psi near-wellbore and 100 psi perforation friction at 25 bpm). The net pressure match is shown in Figure 53. Fracture length is estimated to be about 450 ft with fracture height slightly more than the perforated interval. The production match in Figure 56 and Figure 57 shows how stress-sensitive permeability improves the quality of the flowing pressure match.
