  • Patent number: 8914268
    Abstract: 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.

  • Publication number: 20110246163
    Abstract: Methods and systems for making decisions related to the operation of a hydrocarbon well include 1) 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; 2) 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; and 3) 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. The optimized well potential 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.

  • Publication number: 20110087471
    Abstract: Systems and methods are provided for determining a reservoir property distinct from a near-wellbore/completion characteristic. The methods include obtaining non-transient well data regarding a measurable characteristic of a well that is used to establish a functional relationship between a reservoir property, a near-wellbore/completion characteristic, and the measurable characteristic of the well. A model that relates the reservoir property and the near-wellbore/completion characteristic is used to generate a modeled near-wellbore/completion characteristic value from an input reservoir property value, or vice versa. The input value and the modeled value are then tested against the well data using the functional relationship. The model is used repeatedly with different input values until a validated reservoir property value and a validated near-wellbore/completion characteristic value are identified that at least substantially satisfy the functional relationship.

  • Publication number: 20110067871
    Abstract: Methods of regulating flow in a hydrocarbon well include identifying at least two dissimilar zones in an interval of a well, perforating a well completion in the interval according to a limited-entry perforation strategy, and re-perforating the well completion in the interval according to a re-perforating strategy. The limited-entry perforation strategy is adapted to produce a plurality of limited-entry perforations. The limited-entry perforation strategy varies the perforations within the interval based at least in part on dissimilarities between the at least two dissimilar zones. The re-perforation strategy produces a plurality of re-perforations and is based at least in part on the limited-entry perforation strategy. The re-perforation strategy is adapted to at least substantially align a portion of the re-perforations with a portion of the limited-entry perforations.
