Analyzing well performance is an important step toward increasing profits by improving production techniques. The analysis is made by field tests and examination of well data. The pump intake and Bottom-hole pressures are extremely important factors in analyzing Electric Submersible Pumping (ESP) wells performance. Usually, the bottom-hole pressures for ESP wells are determined by an acoustic well sounding technique (recording fluid level in the annulus). But this method can not be used if the annulus is to be packed off (a packer used).The objective of this study is to develop a method capable of calculating the pump intake pressure (PIP), the bottom hole flowing pressure (BHFP), the dynamic fluid level (DFL), net liquid above pump (NLAP), and the pump discharge pressure (Pdis) for ESP wells using production and completion data only. This method based on supposing the well is natural flow (NF) from pump discharge to the surface. So, the pump discharge pressure is calculated from a two phase correlations (Hagedorn & brown1 for vertical wells and Beggs & Brill2 for inclined wells were used in our study).A VISUAL BASIC computer program is prepared for an easy use. A comparison was made between the real measured values of PIP, BHFP, DFL, NLAP & Pdis in actual wells obtained from an Echometer surveys and the calculated values using the new developed method, the results indicate that the average absolute error between the measured and calculated values is 7%
