Premium sintered mesh screen sand control oil gas well screens
Premium Mesh Sand Screens
Distribute flow evenly and reduce plugging
Premium sintered mesh screens are designed for openhole and cased- hole completions with or without a gravel pack. The screens are manufactured and tested for robustness, reliability, sand control efficiency, and longevity in harsh production environments.
OASIS screens are among the strongest premium mesh screens available with a small outer diameter. This combination enables operators to optimize the completion geometry of a gravel pack during the design and execution of the job, and it sometimes allows for the selection of a larger screen for stand-alone screen completions.
Inner and outer drainage layers
OASIS screens have an inner drainage layer that provides a uniform standoff between the filter medium and the basepipe and an outer drainage layer that provides a uniform standoff between the filter medium and the protective shroud. The two drainage layers help ensure uniform flow over the surface area of the filter medium.
Sintered woven-wire mesh
A premium screen’s performance reflects the filter medium and overall screen construction. The OASIS screen’s filter is made up of multiple layers of a sintered, woven-wire mesh laminate that enhances sand retention and plugging resistance. The wire is woven with either a Dutch weave or a square weave, depending on the desired pore size.
Sintering adds strength and mechanical stability to the mesh and locks the engineered pore geometry, ensuring that pore openings do not change during installation or production and injection. A patented end ring isolates and protects the sintered mesh from heat while the basepipe is being welded.
Protective shroud
A protective shroud fits tightly over the outer drainage layer, enhancing the mechanical properties of the screen assembly. A swaging, or shaping, process centers the screen assembly and shroud and reduces the diameter of the shroud uniformly so that its ID contacts the outer drainage layer consistently. Tight control of tolerances and diameters ensures consistent sizing. Swaging takes place after the screen is assembled and one end of the shroud is welded to the basepipe. The other end is welded to the basepipe after the swaging process.
OASIS well screen
The OASIS well premium sintered mesh screen has four layers (sometimes three) of mesh. Its inner drainage layer is open along the axis of the filter medium tube, with gaps between the filter medium and basepipe. An optional outer drainage layer, available on request, is the same as the inner layer, with gaps between the filter medium and protective shroud.
