Accurate formation-sand particle-size distribution (PSD) is critical for sand-control design. The complete paper aims to establish a set of best practices for generating PSD data from core samples. Historically, PSDs have been measured by one or both methods of either sieve analysis or laser-particle-size analysis (LPSA). Both methods should theoretically yield the same results; however, the results can frequently differ. By addressing common shortcomings in sample selection and preparation, and by evaluating the capabilities of both sieve analysis and LPSA, this work provides clear guidance for confidently conducting PSD measurements.
PSD Best Practices and Procedures
More than 80 cores were used for an in-depth study of particle-size analysis.
