Optimizing well operating plans

摘要

Methods and systems for making decisions related to the operation of a hydrocarbon well include characterizing effective production capacity of a reservoir over space and time based at least in part on a reservoir potential and a near-well capacity; determining an optimized well potential over space and time relative to the characterized effective production capacity using a well model of a simulated well accessing the reservoir, which may be determined based at least in part on an objective function that considers at least one of a plurality of decision-making factors, such as one or more of operations costs, operational risks, and modeled production rates over the life of the well; and determining at least one well operating plan component that can be incorporated into a well operating plan to provide the optimized well potential in a well accessing the reservoir.

1. A method for hydrocarbon well decision-making, the method comprising:
characterizing reservoir potential of a reservoir over space and time using a reservoir model; characterizing a near-well capacity of a formation adjacent to a well drilled to access the reservoir using a near-well model of a simulated well accessing the reservoir, the near-well model considering effects on the formation over time and space due to at least one of particulate movement, filter-cake presence, and scale build-up, wherein the near-well capacity comprises a capacity of the formation adjacent to the well to flow fluids without one of triggering and initiating a negative production event; characterizing an effective production capacity based at least in part on the characterized reservoir potential as modified by the characterized near-well capacity; determining an optimized well potential over space and time relative to the characterized effective production capacity using a well model; and determining at least one well operating plan component that can be incorporated into a well operating plan to provide the determined optimized well potential in a well accessing the reservoir.
