Sand retain control - is a complex solution

The efficient sand retain control increases productivity and maximum recovery rate. To reach higher performance levels you need to ensure sufficient initial open flow area (permeability), high anti-clogging capacity (residual permeability), advanced erosion and corrosion protection. Prevention of sand clogging the filter layers depends on the formation of “sand bridges” on top of the filter layer in a way allowing liquids to flow freely and retaining “adverse” sand.

OMEGA *

Design: Omega* — is a unique equipment execution. The filtering layer is not wrapped around the perforated pipe but sintered with the external safety case for minimum welding process involved and maximum integrity achieved.

Filtering layer: Omega* screens superior design solutions outstand conventional square-weave mesh by the sand retain control and residual permeability indexes.

Mesh optional weaving allows making wider range of pores between the meshes. Three types of screen (Fine, Medium, Coarse) retain particles of almost every size.

ADVANTAGES Flow high efficiency - sufficient residual permeability and anti-clogging capacity significantly influence the well rates and the service life. Corrosion protection - various execution of equipment depending on the well conditions (high temperature, CO2, H2S, etc). Erosion protection - pores 3D changing structure retains heterogeneous sands, prevents clogging, promotes high residual permeability and protects from the erosion. All these features represent the key factors for the wells with high pressure.

APPLICATION

Omega* premium filtering layer of the new generation represents perfect solution for sand recovery problem in vertical, horizontal and subhorizontal wells with the following conditions:

- Unconsolidated oil/gas saturated sand

- Prone to corrosion wells with high temperatures

- Horizontal wells with heterogeneous sands

Solution
Composition:

The sand retain control physics is based on the filter layers heterogeneity for formation of highly-permeable media behind the filter.

Soldering of this layer with safety case provides industry latest achievable strength properties, the “adverse” sand retain control means and minor particles passes.

Filter screen:

This patented technology is unique.

X2 weave type allows to reach 3D maximum filtration in conditions of sand heterogeneous properties at well hole horizon or in wells rich in minor particles.

Such type of weaving helps to achieve the filter outstanding erosion protection.

Design

Premium Screen Filters consist of sintered meshes and the safety case formed in a layered filter material. The filter configuration allows to achieve 20-30% of open flow area with filter durability comparable with the base pipe rigidity which provides rotation of the filter during set-through long descending or rotation at the open hole replacement.

The inner filtering material provides constant discharge across the whole surface reducing the flow velocity through the filter thereby improving the sand retain control and diminishing the erosion.

Due to the filter sintered filtering layer enhanced rigidity, the filter shape may be adjusted without pores opening and sand retain properties changing.

  • filter durability is comparable with the base pipe rigidity
  • the inner filtering material provides constant discharge
  • the filter shape may be adjusted without pores opening
