Brochure Screens and Inflow Control Devices
Broadest, most versatile portfolio in the industry.
Schlumberger specialty screens address the emerging unconventional sand control applications, where conventional gravel packs or screens or both are insufficient, such as heavy oil applications in thermal or nonthermal environments. These screens meet rigid quality control standards to ensure maximum screen strength, erosion resistance, and sand retention.
The MeshRite stainless steel wool screen delivers high flow capacity and plugging resistance with a patented 3D filter formed by wrapping layers of compressed steel wool onto a perforated basepipe and then covering it with a perforated shroud. The 40%-open flow area and greater-than 3,000 D air permeability result in almost no additional resistance to flow in the near-wellbore area or across the screen.
This economical screen reduces completion costs compared with gravel packs and many conventional screen alternatives and is ideal for reservoirs with unknown or poorly defined grain size distributions or varied grain sizes.
The PumpGuard intake screen and valve assembly integrates MeshRite stainless steel wool screens with a pressure-activated cone valve that keeps sand-laden production flow away from the artificial lift pump and opens only after fluid flow is compromised by sand plugging. The valve can be set at the end of the screen, or multiple valves can be configured between screen sections to maximize pump lifetime.
FacsRite screens comprise premium-medium disks that are flush mounted and secured onto a basepipe, so the open flow area can be economically tailored to the well's productivity or injectivity requirements. In addition, the construction means the screens can be treated just like casing, and even drilled into place. Their high strength makes them a good alternative to wire-wrapped and prepacked screens for gravel-pack, frac-pack, and stand-alone screen applications.
Horizontal drilling and hydraulic fracturing technology has enabled a rapid growth of production from the Mississippi Lime Formation during the last five years. Well drilling and stimulation designs are being continuously improved, resulting in higher initial production rates.
High flow capacity and plugging resistance optimize the balance of sand control and well productivity, even for high-viscosity oil.
Challenges of tight fracture-to-pore pressure window in unconsolidated reservoir overcome by meticulous collaboration, completion design, planning, and execution.
The Russkoe oil and gas field was discovered in 1968. It is one of the biggest and complex fields in Russia. It has yet to be put to production, however the development is already concerned by a number of geological and operational issues, such as high crude viscosity; remote location (beyond the Polar Circle); considerable heterogeneity; compartmentalization of poorly cemented sandstones; as well as the presence of extensive gas cap, bottom water, and thick permafrost zone.
Heavy-oil wells in northern South America fields are becoming increasingly more common; e.g., fields such as the Faja in Venezuela and the Llanos in Colombia are growing exponential in importance. A common thread in all of these wells is the requirement for completions that accommodate challenging environments and sand-management systems that satisfy the production goals for the field and extend the life of the reservoir.
