Implementation of Artificial Lift Technique for Optimum Production in Oil Wells of Kirkuk Field

Prosper software is used for simulating the natural production rates. Prosper calculated both natural and optimized production rates for the existing well, based on the available data. At the early or initial time, the performance of the well deliverability is very high, but after several years of production, production rate declined to a certain level for this well in Kirkuk oil field. Natural well capacity can be defined by using four different approaches; Darcy, Pi-Entry method, Fetkovich's and Vogel method. Actual production rate of the well is known from the given data. The approach which gives the result of the rate closer to the actual production rate will be chosen to implement artificial lift. To optimize production and to get initial rate, artificial lift will be designed; both ESP (Electric Submersible Pump) and Gas lift. Sensitivity analysis are also performed for all the cases of the current well, considering the effects of two different central parameters; which include operating frequency and gas oil ratio for ESP design; Gas injection rate and Gas liquid ratio for Gas lift design for the well output, to obtain a model of behavior of the production system and determining optimal input parameters. Also selecting the suitable equipment depending on the available data of well stream and well properties. To conclude, designing ESP will give an effective production rate as compared to Gas lift method, based on the application of sensitivity analysis and the cost of each method.
