Hydraulic fracturing is often used to increase the productivity of oil and gas well. It commonly makes a vertical fracture from the wellbore growth into the formation which is has a higher conductivity than its formation conductivity, so it can increase the fluid flow from formation to the wellbore. <br /> <br /> <br /> <br /> <br /> As we know that production performance of oil and gas well could be described as a relationship between flow rate and flowing bottom hole pressure. The Study of K.H.Guppy shows that producing fractured wells at high flow rates will cause non-Darcy effects in the fracture. <br /> <br /> <br /> <br /> <br /> The final project derives dimensionless gas IPR (Inflow Performance Relationship) equation in fractured well and the effect of non-Darcy flow in fracture, based on K.H.Guppy equation. The method that used to develop IPR is using hypothetical data, like reservoir fluids properties data variation, fracture geometry data variation, rock properties and reservoir data variation which are applied to K.H.Guppy equation and produced hundreds of data that produce the plots. And then we find out the relationship between the ratio of flowrates with maximum flowrates and the ratio of flowing bottom hole pressure with the average reservoir pressure at the condition of pseudo-steady state flow for all variation data. Regression analysis had been conducted to obtain the proposed equation. <br /> <br /> <br /> <br /> <br /> The proposed equation could be used to construct IPR curve for fractured well, using the pressure and production data.
