Abstract:

Tunnel Hydraulic Fracturing is one method of well fracturing operation which generates tunnel in proppant filled fractured rock, near wellbore. The tunnels are in-between packs of proppant. The occurrence of tunnel is caused by certain pumping technique during hydraulic fracturing operation. Frac fluid is pumped continuously, along with proppant is pumped intermittently. These tunnels generate high conductivity media in the fracturing geometry. The subject well was initially flow tested intermittently with 95% to 100% oil cut. The permeability from log correlations is 8 mD, with 1824 Psireservoir pressure, from surrounding wells. Rock mechanic and type of stresses were evaluated to determine tunnel fracturing candidacy. After designing Tunnel Fracturing Design, operationally Pre-fracturing test sequences was executed, which is followed by re-design and operation of Mini frac test. The final design is followed by performing pulsed Mainfrac. The Tunnel Fracturing geometry was computed by service provider software, and the Productivity Index PI by spreadsheet. The Conventional Fracturing and its PI was computed by using spreadsheet. The Tunnel Hydraulic FracturingPI was as much as 4.22 while Conventional Fracturing was 2.05.
