Sand Control in an Ultra-Fine Sand Environment
SPE Annual Technical Conference and Exhibition, 1997Abstract Over the years, gravel packing has emerged as one of the most successful techniques in controlling the production of sand where formations are poorly consolidated. The technique is based on the successful placement of a homogeneous sand or gravel layer between the formation and a porous mechanical retainer (

Sand harm in Taklimakan Desert highway and sand control
Journal of Geographical Sciences, 2003Reputed as a wonderful achievement of the world’s highway construction history, the Taklimakan Desert highway is now facing serious sand drift encroachment problems due to its 447-km-long passage of sand sea consisting of crescent dunes, barchan chains, compound transverse dune ridges and complex megadunes.

Sand Casting Dimensional Control
2009Dimensional accuracy and variability are critical factors in the casting process that must be considered at each stage of the process. Dimensional accuracy is an indication of how close a casting dimension is to design intent (the actual target value). Dimensional accuracy is often referred as a system error.

Stability of Sand Arches: A Key to Sand Control
Journal of Petroleum Technology, 1970Sand production, from a well completed in an incompetent formation without a metal screen, can be attributed to failure of the sand to form a stable arch around the wellbore or over a perforation. This study shows the usefulness of having a sand of high grain strength outside the perforations, and indicates that even a low-strength plastic can provide ...

To assure the success of sand control job in cased and cemented wellbore it is essential to proper design and execute the perforating program. The definition of adequate number of perforations with sufficient depth of penetration (length) will allow production with desired production rate.

Flexible Sand Barrier (FSB): A Novel Sand Control System
Proceedings of SPE California Regional Meeting, 1989ABSTRACT A series of experiments were conducted to determine the utility of a Flexible Sand Barrier (FSB) (helically wound flexible metal tubing) as a permeable casing within horizontal boreholes. These experiments focused on its production capacity and filtering capability. A test cell was developed which allowed testing over a range of

Optimizing Sand Control Design Using Sand Screen Retention Testing
SPE Nigeria Annual International Conference and Exhibition, 2014Abstract Sand retention tests have been widely accepted as one of the methods of sizing screens for Stand Alone Screens (SAS) in open hole completions. The results of such tests are, however, highly dependent on the experimental conditions and prone to artefacts; small and apparently innocuous changes to the test conditions can cause ...

Sand Control: Sand Characterization, Failure Mechanisms, and Completion Methods
Proceedings of SPE Annual Technical Conference and Exhibition, 2002Abstract Sand production has historically been a problem associated with some consolidated, poorly consolidated, and unconsolidated sand formations. The result is usually lost production due to formation sand and fines plugging gravel packs, screens, perforations, tubular, and surface flow lines or separators.

Typical Sand Production Problems Case Studies and Strategies for Sand Control
Proceedings of SPE Annual Technical Conference and Exhibition, 1991ABSTRACT This paper presents analyses of five typical sand problems commonly observed in the field. The causes and progress of these sand production problems are explained using field data to help field engineers gain a better understanding of the various sand problems encountered.

Stress Measurements for Sand Control
Proceedings of SPE/ISRM Rock Mechanics in Petroleum Engineering, 1998Abstract Production of sand from a reservoir is a well known problem in the oil industry. Classically, it is solved by a gravel-pack or frac-and-pack type of completion. This approach, although resolving the sand production problem, has the important drawback of severely reducing the output of the completed well ...
