Effects of perforation entry friction on bottomhole treating analysis
Analysis of field and laboratory data shows that variations in pressure drop due to changing perforation entry friction tends to strongly influence the prediction of fracturing treatment performance. This paper presents experimental data on perforation entry friction as it affects fracturing treatment design. Pre- fracturing treatment planning practices include examination of numerous treating pressure charts in an effort to determine formation type curves, which are used to anticipate fracturing treatment performance and screenout modes. Perforation entry friction may vary greatly because of erosion of the perforation and near wellbore fracture, and this changing friction pressure is often not properly accounted for in planning. This paper presents the following: 1.Discussion and data (laboratory and field showing the degree of perforation erosion encountered in fracturing operations. 2. Proposed guidelines to determine when to alter proppant schedule to account for proppant erosion to perforations, cement sheath, and formation.
