==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.
