Abstract Guidelines for sand control completion technique and gravel size selection are presented. These new criteria are based primarily on reservoir sand size distribution. Emphasis is on formations with very high fines content and a wide distribu

in case of voids in the gravel pack. US 30/60 mesh ceramic proppant was selected for the B25 fracpacks based on laboratory testing, which showed it to provide the best balance of sand bridging, retained permeability and low plugging characteristics. To help ensure proppant placement in the casing/screen annulus over the entire reservoir inter

A well screen is a filtering device that allows ground water from unconsolidated and semiconsolidated aquifers to enter the well, while at the same time keeping the majority of sand and gravel out of the well and out of the pump. A ... Well Screens and Development Techniques ...

The formation sand is held in place by properly sized gravel pack sand that, in turn, is held in place with a properlysized screen. To determine what size gravelpack sand is required, samples of the formation sand must be evaluated to determine the median grain size diameter and grain size quality of the sand used is as ...

A sandcontrol method used to prevent production of formation sand. In gravel pack operations, a steel screen is placed in the wellbore and the surrounding annulus packed with prepared gravel of a specific size designed to prevent the passage of formation sand. The primary objective is to stabilize the formation while causing minimal impairment to well productivity.

ABOUT SAND. Sand, along with gravel, silt and clay are collectively known as sediment, and are produced by the mechanical and chemical breakdown of disaggregated from the original source rock, this material is then eroded and transported by either wind, water or ice, often ending up at the deposits of rivers or lakes, as sand dunes, or ultimately as sediment in the sea.

Sand control is a constant problem in soft or weak geological formations. Thousands of feet downhole, formation sand can choke oil or gas production – and if it isn't filtered out, this sand can damage equipment downstream. 3M™ Ceramic Sand Screen Systems are engineered to simplify complex sand control methods.
