Sand management/control
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.
The authors of this paper describe a project in which retrofitted autonomous inflow control devices were deployed successfully in a field to minimize water production and maximize oil recovery.

The authors of this paper describe a coating designed for enhanced erosion resistance for standard wire-wrapped screens that consists of ceramic or hard metal applied by plasma spraying. -
With the higher adaptation of flow-control devices in recent years to improve flow segmentation and reduce the premature failure of sand control because of highly localized flow, flow-control-device implementation is becoming an integral part of sand-management strategy.

The authors of this paper propose an automated approach to sand prediction and control monitoring that improved operational efficiency by reducing time spent on manual analysis and the decision-making process in a Myanmar field.

This paper discusses tools and techniques used to localize a tubing leak in a horizontally completed multilateral well, identifying the bore responsible for sand production and providing relative sand quantification at differing flow rates.
-
The trend in fracturing designs has been longer stages with more perforation clusters, which save time and money. But there are a couple of companies testing whether shorter is better for production.

The first long-haul overland conveyor system to deliver proppant is under construction in the Permian Basin.
-
This paper describes an intelligent completion design installed in two deepwater wells with dual-zone stack-pack sand-control lower completions and the installation of an intermediate string to isolate the reservoir in each zone.

Over 1,000 hours of remotely monitored continuous production was achieved on an unmanned platform—a first for standalone offshore solids management in the North Sea.

This paper presents field cases of a rigless wireline logging technique that accurately locates sources of water production in cased wells with standalone sand screens in an offshore field in the Caspian Sea.

This paper presents a physics-based approach to predict sand production for various reservoir and completion types, explored through a case study of recent production wells in a sandstone reservoir development.
