  • Huff and Puff Feasibility in Eagle Ford

    Huff and Puff Feasibility in Eagle Ford

    Based on an 8 well calibrated simulation model in Eagle Ford, the feasibility of huff and puff gas injection for a full field development was investigated. The actual pilot gas injection was part of the calibration. The performance under different operational scenarios including injection rates, injection/production sequence, and scheduling were investigated and reported to support the management’s decision.

  • Frac size vs. Spacing optimization in Permian

    Frac size vs. Spacing optimization in Permian

    NITEC’s client needed proper optimization for well spacing and frac size. Through a 6 well simulation model, NITEC provided the optimum spacing and frac size for different benches of the producing formations. Optimum frac sizes and spacing were different for different benches. The client increased capital efficiency by differentiating the completion and spacing practices among the different benches.

  • Refracing Evaluation in Eagle Ford

    Refracing Evaluation in Eagle Ford

    NITEC’s client needed decision support on deciding between refracing existing wells and drilling infill wells in the same area. NITEC provided analysis of both options by utilizing a five well simulation model that is calibrated for reservoir and geomechanical parameters in the area.

  • Unified EOS generation for Woodford

    Unified EOS generation for Woodford

    A unified EOS model was generated for Woodford shale using 20 samples covering from dry gas to gas condensate.

  • Well Spacing optimization in Bakken and Three Forks

    Well Spacing optimization in Bakken and Three Forks

    NITEC’s client needed an evaluation of different spacing in Bakken and Three Forks development for exploration purposes. Using publicly available data around the exploratory acreage a representative simulation model was calibrated for reservoir and geomechanical parameters. This information was migrated to the exploratory area by changing the reservoir characterization accordingly. Further sensitivities to optimize spacing and landing for this new area were performed.

  • GOR vs water production relationship in Permian

    GOR vs water production relationship in Permian

    NITEC’s client needed evaluation on the relationship between GOR behavior and water production and water saturation in Permian. NITEC explained the relationship between water saturation, wettability, and GOR through modeling. This knowledge impacted the understanding of the reserves and long term production behavior.

  • Completion optimization in Eagle Ford

    Completion optimization in Eagle Ford

    NITEC’s client needed to improve its completion practices to recover more oil in Eagle Ford. Simulation study led to a design that improved the Infill of an infill well performance such that the new well produced more than the original parent well’s total production within months. The optimization was based on a 4 well history matched simulation model.

  • Compressor design criteria based on gas injection performance in Eagle Ford

    Compressor design criteria based on gas injection performance in Eagle Ford

    NITEC’s client needed guidelines to build proper size compressors to be utilized in huff and puff operations at Eagle Ford. Using models created at different depths containing different oil types, operational ranges (pressure and injection rate) of possible huff and puff operations were determined for proper compressor design.

  • A quick study to evaluate the potential of a field in Permian for acquisition

    A quick study to evaluate the potential of a field in Permian for acquisition

    NITEC’s client needed a quick evaluation of a field that they were planning to bid on. They used NITEC’s model to understand and evaluate the upside potential by infill drilling and assess the uncertainties associated with the project. The analysis provided by NITEC helped the client’s decision to bid or not on the prospect.

  • Frac size vs. Spacing optimization in Permian

    Frac size vs. Spacing optimization in Permian

    NITEC’s client needed proper optimization for well spacing and frac size. Through modeling, NITEC provided the optimum spacing and frac size for different benches of the producing formations. Three reservoir simulation models were generated to create an optimum solution that would represent multiple regions in the area. Improved understanding of the reservoir and the spacing optimization that takes into account the interference supported the client’s decision making on capital spending.

  • Huff and Puff Pilot Design

    Huff and Puff Pilot Design

    Based on a 9 well history matched model in Eagle Ford, feasibility of huff and puff gas injection for a full field development was investigated. The operational pressure range, the injection schedule, and the injection rate were optimized to achieve a successful huff and puff pilot in this area to confirm the feasibility and maximize the knowledge.
