Detecting interference between hydrocarbon wells

A system for managing a well in a subsurface region, the system comprising:

• one or more processors configured to perform operations comprising:
• obtaining production data about the well;
• generating a simulated average reservoir pressure at the subsurface region that includes the well;
• computing a difference between an average reservoir pressure obtained from the production data and the simulated average reservoir pressure;
• determining, based on the computed difference, a performance deviation with reference to a particular area of the subsurface region that includes the well;
• comparing the performance deviation to a predetermined threshold value that represents an acceptable tolerance for variance in performance of the well;
• and
• triggering, when the performance deviation exceeds the predetermined threshold value, a particular type of automated response comprising an action that addresses the variance in performance of the well.

A non-transitory computer storage medium encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform operations for managing a well in a subsurface region, the operations comprising:

• obtaining production data about the well;
• generating a simulated average reservoir pressure at the subsurface region that includes the well;
• computing a difference between an average reservoir pressure obtained from the production data and the simulated average reservoir pressure;
• determining, based on the computed difference, a performance deviation with reference to a particular area of the subsurface region that includes the well;
• comparing the performance deviation to a predetermined threshold value that represents an acceptable tolerance for variance in performance of the well;
• and
• triggering, when the performance deviation exceeds the predetermined threshold value, a particular type of automated response comprising an action that addresses the variance in performance of the well.
