Sieve Shaker Data for Obtaining Proper Well Completion Method

Abstract

The sand accumulates at the well leads to increase in sand production resulting in lost production and increased well maintenance cost. The main objective of this research is to evaluate sand produced from the field and to propose a suitable prevention sand method.Four samples of sand with different mass size are prepared for the test and then placed in a sieve shaker with openings in the decreasing order of sieve size. Sieves of sizes 2000, 1000, 500, 250, 125, 36 microns and a no sieve pan were used to sample the sand. Granular particles are accumulated on different sieves, which give the particle size distribution of the samples.From sieving analysis, the results showed that for well one the majority of the sand material is retained on the 500-size sieve. While, for the second sample the results showed that the percentage of sand accumulated on the 125 micron is the highest, which indicates that the sample consists of fine particles. Further, the highest percent weight retained of this sample is reported at mesh size of 125 micron. Further, the sieve analysis for the rest of samples indicated that maximum of the particles of the sand sample belong to the large category of particle size classification.This can be justified as the highest percent weight retained of both samples are reported at the larger micron size mesh particularly at 2000 and 1000 micron mesh sizes. Based on tiffin Criteria, the results elaborated that well one can use standalone screen or wire-wrapped screen and for the well two must use mesh screen. While for well three and well four, it is suggested to use gravel pack that can utilize slotted liner since these types of sand are non-uniform sand.
