Sand management/control
This paper presents the completion strategy implemented in an intelligent well completed in Malaysian deepwater Block K.
To avoid costly interventions like sidetracking or wellbore abandonment, a check-valve system was installed near the sandface within three injector wells which prevented the mobilization of fines from the reservoir into the wellbore by stopping backflow.
This paper outlines issues to be resolved during facility design and provides guidelines, calculations, and examples for sand-handling steps to be implemented after separation.

Could the development of consistent practices be a critical first step on our journey toward achieving improvements in completion quality? The list of practices is quite long. For sand-control applications, we could start with those activities that occur early in the design process. -
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.
