First Claim
Patent Images
1. A fracturing method, comprising:
- receiving input parameters specifying fracturing requirements;
electronically accessing formation data associated with a target formation;
using a computer processor to dynamically generate a fracturing plan for at least one of a plurality of boreholes in the target formation, the plan including potential fracture locations and lengths that account for existing or planned fracture locations along others of the plurality of boreholes and that further account for the received input parameters and the accessed formation data; and
fracturing the target formation along the plurality of boreholes in accordance with the fracturing plan.

Abstract
A casing wear estimation method includes obtaining a set of input parameters associated with extending a partially-cased borehole and applying the set of input parameters to a physics-driven model to obtain an estimated casing wear log. The method also includes employing a data-driven model to produce a predicted casing wear log based at least in part on the estimated casing wear log. The method also includes storing or displaying information based on the predicted casing wear log.

7. A dynamic fracturing method, comprising:
-
receiving a desired fracture length and desired fracture spacing information from an input source; electronically accessing formation data pertaining to a target formation from one or more databases; using a computer processor to dynamically generate a zippered fracturing plan for multiple boreholes in said target formation based on the desired fracture length and desired fracture spacing information; using the computer processor to monitor for modifications to the desired fracture length, desired fracture spacing information, and formation data; using the computer processor to dynamically update the zippered fracturing plan based on said modifications; and fracturing the target formation along the multiple boreholes in accordance with the updated zippered fracturing plan. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A computer-readable medium storing software code which, when executed, causes a processor to:
-
generate a first list of boreholes in a target formation, at least some boreholes in the first list associated with one or more fractures; generate a second list of boreholes in a target formation, at least some boreholes in the second list associated with no fractures; for a selected fractured borehole in the first list, identify a corresponding non-fractured borehole in the second list that is adjacent to the selected fractured borehole in the target formation; and determine a zippered fracturing plan for the identified non-fractured borehole in accordance with input parameters specifying desired fracture length and spacing; and wherein the borehole is fractured based on the plan. - View Dependent Claims (15, 16, 17, 18, 19, 20)
