Particle Size Distribution Measurement Techniques and Their Relevance or Irrelevance to Sand Control Design

2014 SPE International Symposium and Exhibition on Formation Damage Control
Abstract

Particle size distribution (PSD) is used for various purposes in sand control: decision between various sand control techniques (e.g., Tiffin criteria), sizing of the filter media (sand screens and/or gravel packs) through either rules of thumb (Coberly, 1937; Saucier, 1974; etc.) or physical experiments or theoretical models (Chanpura et al., 2012, 2013; Somnath et al., 2011, 2012). PSD of formation sand samples are also often used to generate “simulated” formation sand for laboratory experiments. Two most commonly used techniques for PSD measurements are sieve and laser, while some engineers use one technique for no obvious or justifiable reasons, others use both techniques for measurements and don’t know what to do with the data when significant differences exist in PSDs obtained from each technique. Although the inherent limitations of, and the differences between, these two techniques as well as other factors impacting the measurements are well known, a systematic study as to what is relevant to sand control along with when and why is lacking. In this paper, we critically review the current practices in PSD determination and use and misuse of the information obtained from those measurements, propose a methodology towards determination of what is relevant, when and why, and present our initial experimental results that support our conclusions.
