  • Fracture Characterization

    Fracture Characterization

    A highly fractured and faulted reservoir in Mexico with an active aquifer was successfully characterized by NITEC’s in-house technology. Reservoir simulation resulted in the identification of highly productive zones which were confirmed by drilling.

  • Thermal recovery

    Thermal recovery

    A verification of the process was carried out for a thermal recovery process – insitu upgrading of hydrocarbons. Thermal simulation correctly correlated with laboratory results and a U.S. field evaluation considered Huff-n-Puff and continuous injection.

  • Compositional Simulation

    Compositional Simulation

    This light-oil field in Venezuela with a thin oil rim and overlying gas condensate zone was characterized and simulated. Understanding reservoir performance required identification and characterization of asphaltene deposition in the oil rim and detailed simulation of over 100 wells with multiple production strings. Simulation predictions provided new completion alternatives and workovers to improve future oil recovery.

  • CO2 Injection

    CO2 Injection

    An integrated reservoir study was carried out on a near depleted oil field in Wyoming discovered in 1916 with over 700 completions. The simulation model history match indicated substantial remaining oil in place. Extended black-oil simulation of CO2 WAG and continuous CO2 injection processes indicated significant tertiary oil recovery potential. Full-field development is in the planning stages.

  • Fracture Characterization

    Fracture Characterization

    Limited performance and wellbore data in a recent oil discovery in India suggested the existence of a natural fracture system. Seismic, wellbore, and performance data, along with NITEC’s unified capillary pressure technology were used to confirm and describe the vertical and areal fracture distribution. Field development is being planned accordingly.

  • Secondary or Tertiary Recovery

    Secondary or Tertiary Recovery

    A prolific oil field in Wyoming with significant primary and secondary recovery was evaluated for bypassed secondary and tertiary oil potential. The natural fractures in the formation and the historical water injection resulted in little additional secondary oil recovery potential. Accordingly, the remaining oil in place was found to be insufficient to warrant an economically viable CO2 injection program. Other tertiary recovery processes are under consideration.
