Sand management/control
Three papers are highlighted as the primary contributions because of their broad industry relevance. They focus on improving formation particle-size characterization, expanding the application of openhole gravel packs in depleted and compartmentalized reservoirs, and advancing the understanding of capillary pressure in sand production.
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.
This paper discusses the successful execution of two openhole gravel-pack completions in two Gulf of Mexico fields with depleted reservoirs.

Although multiple-zone, downhole sand-control-tool systems have been in use since the early 1990s, these systems have been designed for jobs that require only low pump rates with low pressure differentials. -
Standalone-sand-screen (SAS) completion, especially in horizontal gas wells with high potential for sand production, typically suffers from premature failure caused by sand erosion resulting from high velocity in the annulus near the heel section.
-
Large amounts of clay minerals are present in shale; shale’s resulting instability is a major problem while drilling.
-
Upstream separation processes remain a hot topic for facilities engineers. Striving to design separators with the optimal sizing for a variety of reservoir conditions, increasing water cuts, and dynamic gas/oil/water production characteristics is critical, but challenging.
-
Sand production is an unintended consequence of oil and gas production from unconsolidated and semi-consolidated reservoirs, causing damage to surface and subsurface well equipment and reducing the hydrocarbon productivity.
-
This paper shares the engineering approach used to determine where and when sand control was needed in offshore Malaysia on the basis of geomechanical sand-free critical-drawdown-pressure evaluation for the selected well type, configuration, and completion.
-
Traditionally, sand-control equipment is used to prevent sand from entering the wellbore. An alternative is to produce solids with the well fluids and separate them at the surface.
-
This paper presents results from a nondestructive core-strength-index tester that is less destructive than the Schmidt hammer and less intrusive, easier, faster, and less expensive than the core scratch tester.
-
Facilities sand management is tasked with the goal of ensuring sustained hydrocarbon production when particulate solids are present in well fluids, while minimizing the impact of the produced solids on surface equipment. How to do that?
-
This paper discusses the available methodologies for remediation of a pipeline affected by sand and presents examples where the discussed methodologies have been applied.
