Abstract
A method may include generating an optimal operational window (OOW) that specifies operational parameter values for drilling operations using equipment at a rig site, based on data indicative of rig state and formation characteristics, and based on mutation-based optimization of the operational parameter values; and instructing a control system to perform the drilling operations according to the OOW using the equipment at the rig site.
Claims20
A method, comprising:
- generating an optimal operational window (OOW) that specifies operational parameter values for drilling operations using equipment at a rig site, based on data indicative of rig state and formation characteristics, and based on optimization of the operational parameter values using at least one heatmap corresponding to each operational parameter, the generating the OOW including performing formation alignment on offset well data for multiple wells with respect to the formation characteristics, the OOW indicating a range of depths at which the optimized operational parameter values are used by the equipment at the rig site based on an average length of each formation characteristic;
- instructing a control system to perform the drilling operations according to the OOW using the equipment at the rig site;
- responsive to instructing the control system, using a drill bit included in the equipment to deepen a borehole by breaking rock in a formation;
- receiving, during the drilling operations, field data associated with the drilling operations;
- and
- updating the OOW based in part on the field data.
A system, comprising:
- at least one processor;
- memory accessible to at least one of the at least one processor;
- and
- processor-executable instructions stored in the memory and executable to instruct the system to:
- generate an optimal operational window (OOW) that specifies operational parameter values for drilling operations using equipment at a rig site, based on data indicative of rig state and formation characteristics, and based on optimization of the operational parameter values using at least one heatmap corresponding to each operational parameter, the generating the OOW including performing formation alignment on offset well data for multiple wells with respect to the formation characteristics, the OOW indicating a range of depths at which the optimized operational parameter values are used by the equipment at the rig site based on an average length of each formation characteristic;
- control, according to the OOW, a drill bit included in the equipment at the rig site to deepen a borehole by breaking rock in a formation;
- receive, during the drilling operations, field data associated with the drilling operations;
- and
- update the OOW based in part on the field data.
One or more non-transitory computer-readable storage media comprising processor-executable instructions to instruct a computing system to:
- generate an optimal operational window (OOW) that specifies operational parameter values for drilling operations using equipment at a rig site, based on data indicative of rig state and formation characteristics, and based on optimization of the operational parameter values using at least one heatmap corresponding to each operational parameter, the generating the OOW including performing formation alignment on offset well data for multiple wells with respect to the formation characteristics, the OOW indicating a range of depths at which the optimized operational parameter values are used by the equipment at the rig site based on an average length of each formation characteristic;
- control, according to the OOW, a drill bit included in the equipment at the rig site to deepen a borehole by breaking rock in a formation;
- receive, during the drilling operations, field data associated with the drilling operations;
- and
- update the OOW based in part on the field data.
