  7. Abstract:
  8. Considering that hydrocarbon production, reduces energy of reservoir and causes part of the valuable compounds remaining in the oil or gas reservoir and can not be extracted by reservoir energy, so optimization of production by control flow rate, drilling new wells and applying lOR and EOR methods in order to increase hydrocarbon recovery is necessary. Gas and water inject through injection well into the reservoir for improve oil recovery. As implementation of different production and injection scenario is very expensive. Simulation of different method and applying the best is very helpful and necessary. In this study we use Eclipse software that is one of the best software that can simulate reservoir by solve equation through numerical method and investigate different JOR method including infill drilling, water injection, immiscible gas injection and WAG methods on one of the ICOFC oil field.The following parameters have been analyzed in different scenarios:• Numbers and location of new injectors and producers • Various completion of these wells in different layers (Horizontal, Vertical) • Field production and injection rate • WAG Cycle and WAG ratio(for WAG injection) Sensitivity analysis of reservoir performance due to the each parameter was performed. Reservoir behavior parameters such as ultimate recovery, plateau period, water cut and GaR production were considered to rank development alternatives for each scenario.These studies showed that gas injection of associated and make-up gas into the crest of reservoir gave superior results in terms of reservoir performance compare to all other development strategies.WAG injection are the next superior candidates
