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 discusses the successful execution of two openhole gravel-pack completions in two Gulf of Mexico fields with depleted reservoirs.
By integrating experimental and mathematical modeling approaches, this work aims to advance the understanding of sand-detachment dynamics and formation instability under varying saturation conditions.

Multilayered metal-mesh screens (MMSs) are widely used as standalone screens for sand control in unconsolidated formations. It is often found that screens with the same filter-layer nominal rating perform differently. -
This paper presents a combined experimental and numerical-modeling study on sand-screen performance. The objective is to develop an improved methodology for optimal sand-screen-aperture selection by addressing some of the limitations present in existing sand-retention tests.

In this paper, gravel-pack pore size is evaluated further by use of the permeability of the gravel pack and other methods. A new sizing method is proposed that is based on the effective formation size and the gravel-pack pore size.

Telok is a gasfield development in the Malay basin offshore Terengganu, Malaysia. This paper discusses the program learnings and operational improvements captured while completing eight new wells in 2012 and 2013.

Many of us have been so busy chasing the next well and the upcoming job that our skills in the area of optimizing our completions may have become a little rusty. Now is a great time to knock off that rust and revisit our best-laid plans.

An integrated approach to sand management is crucial to address sanding risk in producers and injectors in a North Sea mature field.
-
Chemical sand consolidation works by pumping chemicals downhole to strengthen the formation and stop sanding. In most cases reported in the industry, chemical consolidation has been used in short production intervals (less than 100 m).

A deepwater field located offshore Sabah, east Malaysia, features a spar dry-tree unit (DTU) and multiple subsea-hub tiebacks to a floating production, storage, and offloading vessel (FPSO).
-
A well drilled and completed in a marginal field offshore India produced only gas until the oil-bearing sands were perforated and the well was put on commingled-oil-and-gas production.
-
I think it is safe to say that the engineers and companies involved, in either building or using sand-control systems, have made significant strides and have added critical learnings to our industry.
