OPTIMAL DRILLING AND FRACTURING SEQUENCES FOR PLACING NUMEROUS HORIZONTAL WELLS IN TIGHT RESERVOIRS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17959871 titled 'OPTIMAL DRILLING AND FRACTURING SEQUENCES FOR PLACING NUMEROUS HORIZONTAL WELLS IN TIGHT RESERVOIRS
Simplified Explanation
The patent application describes a technique for drilling and fracturing wells using geomechanical properties and in-situ stresses estimation, 3D geomechanics modeling, and hydraulic fracturing modeling for multiple wells.
- Geomechanical properties and in-situ stresses are estimated using collected data and mini-fracking tests.
- A 3D geomechanics model is generated based on a 3D property model and natural fracture network.
- Hydraulic fracturing modeling is conducted for a single well to obtain an optimum pump schedule for a target fracture length and well spacing.
- Hydraulic fracturing modeling for multiple wells is conducted based on a drilling-fracturing sequence to generate symmetric fractures and determine an optimum pump schedule for middle wells.

Original Abstract Submitted
Systems and methods include a technique for drilling and fracturing wells. Geomechanical properties and in-situ stresses for the field are estimated using collected data and results from mini-fracking tests. A 3D geomechanics model for the field is generated based on 3D property model and natural fracture network. First 3D hydraulic fracturing modeling for a single well is conducted to obtain an optimum pump schedule for a target fracture length and well spacing for placing numerous horizontal wells in the field. Then 3D hydraulic fracturing modeling for the multiple wells is conducted based on a drilling-fracturing sequence configured to generate symmetric fractures and to determine an optimum pump schedule for middle wells, considering tensile stress superposition. The drilling-fracturing sequence includes initially skipping fracturing of a drilled well adjacent to a fractured well. The group of wells are drilled and fractured using the sequence.
