Abstract
Systems, methods, and computer-readable media for designing a microseismic monitoring project. The method includes receiving data representing the microseismic monitoring project for at least one subterranean volume, the data including data representing a plurality of factors associated with a design of the microseismic monitoring project. The method also includes conducting a sensitivity analysis to determine a relative sensitivity between at least two of the plurality of factors, and determining whether to update a modelling scenario for the microseismic monitoring project based on the relative sensitivity.
Claims16
A method for designing a microseismic monitoring project, comprising:
- receiving data representing the microseismic monitoring project for at least one subterranean volume, the data comprising data representing a plurality of factors associated with a design of the microseismic monitoring project, wherein the plurality of factors comprises at least one of:
- a type of sensor,
- a sensor sensitivity, or
- a sensor spacing;
- determining a base modelling scenario based on uncertainties, risks, or both associated with the plurality of factors;
- conducting a sensitivity analysis to determine a relative sensitivity between at least two of the plurality of factors for the base modelling scenario, wherein conducting the sensitivity analysis comprises selecting at least one of the plurality of factors based on the relatively sensitivity;
- and
- acquiring additional data configured to decrease uncertainty for the at least one of the plurality of factors by deploying one or more sensors to collect the additional data,
- updating the base modelling scenario using the additional data,
- conducting a sensitivity analysis to determine a relative sensitivity between the at least two of the plurality of factors for the updated modelling scenario,
- determining whether to proceed with conducting the microseismic monitoring project using the design based on the sensitivity analysis for the updated modelling scenario.
A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a computing system, cause the computing system to perform operations, the operations comprising:
- receiving data representing a microseismic monitoring project for at least one subterranean volume, the data comprising data representing a plurality of factors associated with a design of the microseismic monitoring project, wherein the plurality of factors comprises at least one of:
- a type of sensor,
- a sensor sensitivity, or
- a sensor spacing;
- determining a base modelling scenario based on uncertainties, risks, or both associated with the plurality of factors;
- conducting a sensitivity analysis to determine a relative sensitivity between at least two of the plurality of factors for the base modelling scenario, wherein conducting the sensitivity analysis comprises selecting at least one of the plurality of factors based on the relatively sensitivity;
- and
- acquiring additional data configured to decrease uncertainty for the selected at least one of the plurality of factors by deploying one or more sensors to collect the additional data,
- updating the base modelling scenario using the additional data,
- conducting a sensitivity analysis to determine a relative sensitivity between the at least two of the plurality of factors for the updated modelling scenario,
- determining whether to proceed with conducting the microseismic monitoring project using the design based on the sensitivity analysis for the updated modelling scenario.
