Sand control in oil and gas wells
Gravel packing is currently the most widely used sand-control technique for completing wells. More than 90% of all sand-control completions are gravel packs. Because of its flexibility, almost any well at any deviation can be gravel packed. The exception is tubingless completions where clearances do not permit the use of conventional tools. Sand management is an operating concept in which traditional sand control means are not normally applied and production is managed through monitoring and control of well pressures, fluid rates and sand influx. Sand management has proven to be an effective tool in North Sea oil and gas production wells.Sand management has proven to be workable, and has led to the generation of highly favorable well skins because of self-cleanup associated with the episodic sand bursts that take place. Tech Paper Multizone Horizontal Openhole Gravel Pack with External Zonal Isolation and Inflow Control Devices Allows for Production of Left-Behind Reserves in Sand-Prone Reservoirs. Oil production from the Llanos foreland basin in Colombia is seriously affected by sand production and high water cut. Sand production has been successfully controlled with horizontal openhole gravel packs; however, early water breakthrough causing water cuts as high as 90% remained a challenge. These formations are usually geologically young (Tertiary age) and shallow, and they have little or no natural cementation. Sand production is unwanted because it can plug wells, erode equipment, and reduce well productivity. It also has no economic value. Nonetheless, formation sand production from wells is dealt with daily on a global basis. The same holistic sand-management tactic should be applied to remedial sand control. In summary, production from sand-prone reservoirs is a daunting task, with formidable challenges. Sand management and control remain as an old problem but with new challenges because of the suppressed oil and gas prices. Sand Problem in Oil Wells 1.

Sand management has been recognized as one of the main issues during field development in which contributing to over 70% of the world's oil and gas fields. Sand management is a balance of the threats (environmental, safety, process and cost) of producing sand to the surface and the threats of trying to retain it down in the reservoir. In many offshore regions, the geologic formations that produce oil and gas are unconsolidated, which means the sand that makes up these formations is loose or poorly bonded, much like the sand on a beach. As a result, this loose sand can end up inside the production piping in the well or production equipment on the surface. 3M™ Ceramic Sand Screens are a sand control solution for oil and gas operations. They resist erosion, acids, brines and high temperatures to minimize sand production and improve efficiency. To learn more about how 3M can help for your sand screening needs, contact us today. Sand screens are of importance in producing oil, natural gas and water which are often located deep underground. Large drills are used to bore below the surface of the earth to collect oil or gas. Then sand screen is inserted into the bore allowing natural oil, gases to come in while prevent sand out except very fine particles. SegreTECH offers the leading sand separator package to meet your oil and gas production desanding requirements. “More than just a sand trap, our two stage, high pressure sand removal system is designed to contain the large slugs produced by high flowing wells”. This makes risk mitigation the name of the game for sand control completions. As such, you need to explore all of your options. That’s why you need to consider Delta Screens and our complete line of oil and gas well screens. Delta Screens’ state-of-the-art manufacturing facility manufactures long-lasting and top-performing screens.

Sand control refers to managing/minimizing sand and fine production during petroleum production. Sand and fine produced with oil and gas can cause erosion and wear of production facilities/equipments, resulting in production downtime, expensive repairs, and potentially loss of containment (serious safety risk).
Sand control technologies prevent migration of reservoir sand and fines into a wellbore, stabilizes the reservoir, and enhances productivity. Simplify your completion by choosing an engineered, integrated service for your openhole or cased hole application.
