Sand management/control
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.

Skipping one traditional step in the supply chain might save oil and gas companies hundreds of millions of dollars a year while making a meaningful dent in emissions. -
Field examples presented in the complete paper describe principles of data acquisition with a sand-detection tool when run in combination with a production logging string and results of logging in slightly deviated wells completed with sand screens.
-
The complete paper discuses a well with a history of sand production that exhibits long cyclic slugging behavior.
-
Sand-control-installation failures range from minor issues that can be remedied easily to catastrophic events that put the entire well and investment at risk.
-
Sand control has evolved over the years; however, the fundamentals of screen sizing have not changed. Particle-size distribution remains the basis for most designs. Laser diffraction has provided better definition of fines, and greater focus is placed now on particle-shape characterization.

A multizone water-injection project has ultimately proved a method of using intelligent completion interval-control valves in place of traditional sand-control completions in soft sand reservoirs.

In 2014, a research and development (R&D) project was initiated to increase the life expectancy of Gulf of Mexico (GOM) Miocene and Lower Tertiary water-injection (WI) wells, several of which had suffered a severe loss of injectivity within only a few years of completion.

This paper discusses a probabilistic flux and erosion model and work flow that extend the ability to estimate inflow through sand screens on a foot-by-foot basis along the wellbore using the well's completion details, production rate, and reservoir and bottomhole flowing pressures.
-
This paper proposes a new work flow to simulate water-hammer events, the resulting wellbore failure, and sand production in water injectors.

This paper presents the first successful application of ceramic sand screens offshore Malaysia. Ceramic sand screens were considered as a remedial sand-control method because of their superior durability and resistance compared with metallic sand screens.
