Summary. Cased-hole gravel packing is commonly used to control sand production from oil and gas wells. The success of a cased-hole gravel-pack job depends on the ability to effectively pack perforation tunnels, which act as conduits between the reservoir and the wellbore for hydrocarbon production.This project presents a systematic approach for removal of …

Abstract. There are numerous design criteria available for gravel-packs based on the well-mown gravel-la-sand grain size ratio. These rules are mainly derived from the interpretation of compatibility experiments. The favourable gravel-to-sand ratios are determined within the limits set by successful and unsuccessful tests. Because of empirical approach, …
