Abstract
Systems and methods for designing stages that optimize production for a fracturing operation of a wellbore in a reservoir formation are disclosed. To ensure efficiency, a stage design operation generally takes into account fracture efficiency information along the length of the wellbore based on known attributes and use the efficiency information to divide the wellbore into various stages. The stage design system and method provides an automated procedure for stage design that efficiently, accurately, and with minimal human involvement partitions a wellbore along its length such that the fracture operation is optimized.
Claims56
A non-transitory program storage device, readable by a processor and comprising instructions stored thereon to cause one or more processors to:
- receive a plurality of input parameters, each input parameter relating to a wellbore in a reservoir formation;
- calculate one or more efficiency indices for the wellbore based on the input parameters, wherein each of the one or more efficiency indices may vary along a length of the wellbore;
- and
- select one or more stage locations for the wellbore, each stage having a particular length, wherein the selection is done by utilizing an optimization process used to select stage locations based at least in part on at least one of the one or more efficiency indices having a minimal total intra-stage variation along the length of the wellbore.
A method for designing a fracture network staging operation, the method comprising:
- receiving a plurality of input parameters, each input parameter relating to a wellbore in a reservoir formation;
- calculating one or more efficiency indices for the wellbore based on the input parameters, wherein the one or more efficiency indices may vary along a length of the wellbore;
- and
- selecting one or more stage locations for the wellbore, each stage having a particular length, wherein the selection is done by utilizing an optimization process used to select stage locations based at least in part on at least one of the one or more efficiency indices having a minimal total intra-stage variation along the length of the wellbore.
A system, comprising:
- a memory;
- a display device;
- and
- a processor operatively coupled to the memory and the display device and adapted to execute program code stored in the memory to:
- receive a plurality of input parameters, each input parameter relating to a wellbore in a reservoir formation;
- calculate one or more efficiency indices for the wellbore based on the input parameters, wherein the one or more efficiency indices may vary along a length of the wellbore;
- and
- select one or more stage locations for the wellbore, each stage having a particular length, wherein the selection is done by utilizing an optimization process used to select stage locations based at least in part on at least one of the one or more efficiency indices having a minimal total intra-stage variation along the length of the wellbore.
