Abstract
A method of identifying a location of gas breakthrough within a completed production well includes: obtaining production composition data and/or tracer data from the production well; analysing the production composition data and/or tracer data to determine whether gas breakthrough has occurred within the production well; and in response to determining that gas breakthrough has occurred within the production well, examining mud-gas data collected during drilling of the production well to identify a gas breakthrough location within the well where the gas breakthrough has occurred.
Claims14
A method of identifying a location of gas breakthrough within a completed production well, the method comprising:
- obtaining production composition data and/or tracer data from the production well;
- analysing the production composition data and/or tracer data to determine whether gas breakthrough has occurred within the production well;
- and
- in response to determining that gas breakthrough has occurred within the production well, examining mud-gas data collected during drilling of the production well to identify a gas breakthrough location within the well where the gas breakthrough has occurred.
A non-transitory computer-readable medium storing a computer program, wherein the computer program comprises computer-readable instructions that when executed will cause a computer to perform a process comprising:
- obtaining production composition data and/or tracer data from a completed production well;
- analysing the production composition data and/or tracer data to determine whether gas breakthrough has occurred within the production well;
- and
- in response to determining that gas breakthrough has occurred within the production well, examining mud-gas data collected during drilling of the production well to identify a gas breakthrough location within the well where the gas breakthrough has occurred.
A computer comprising:
- a memory, and
- a processor,
- the memory storing computer readable instructions that, when executed by the processor will perform a method comprising:
- obtaining production composition data and/or tracer data from a completed production well;
- analysing the production composition data and/or tracer data to determine whether gas breakthrough has occurred within the production well;
- and
- in response to determining that gas breakthrough has occurred within the production well, examining mud-gas data collected during drilling of the production well to identify a gas breakthrough location within the well where the gas breakthrough has occurred.
