Sand Control Screen: The Ultimate FAQs Guide

0 5

This guidance article covers all key elements, for example, the parts, properties, kind of material, sand control screen design and size, to name just a few.. Read this instruction before you import a sand control screen.

It would help you to become a sand control screen specialist.

What is a Sand Control Screen?

A sand control screen is a device you employ to avoid the introduction of pollutants such as rock and sand.

What is the function of a Sand Control Screen?

Sand control screens are a requirement for oil, water, gas and steam production applications, as well as for any other deep underground production activity.

The drag-force arising from the injection fluid or the drag-force may produce sand.

Similarly, near-bore mechanical failure is also a typical source of formation of sand.

The sand control screens will assist to reduce the negative impact of sand on your system and the possible damage that it might cause.

On bodies dug deep below the surface you should attach sand control panels to catch sand particles, except fine particles.

It functions as a sand-removing separator from the process fluid.

The installation of a sand control screen will thus assist you:

  • Reduce the impairment of machinery due to sand connection
  • Surface protection systems such as separators, pumps, erosion and damage tubes
  • Downhole cavity risks elimination.
  • Cleaning, disposal of sand and maintenance costs are reduced
  • Elimination of difficulties with sand bridging

Why should you use a Sand Control Screen?

You generate fluids that are polluted by many contaminants when you drill into a reserve of subterranean oil, water or gas.

These contaminants must be removed at the drilling point to ensure they are not transferred to the refining plant.

These installations, unfortunately, rarely are able to remove heavy-duty pollutants.

When pollutants are reached, they will lose heavily because of downtime, loss of revenues, cleanup and repair of machinery and equipment.

The whole wellbore can potentially be plugged, which leads to millions of dollars of losses.

What is Screen Bonding?

Screen bonding is a sand control screen utilising several wire mesh layers.

This combines a stronger and more specialised woven product with the filtering demands.

The following benefits are offered to a connected sand screen:

Fixed porous shape to make sand control efficient at high operating pressure

Improved service since it has low porosity and reduced pressure

A monolithic framework for accurate retention of particles and high mechanical properties.

A wide micrograde to manage a wide range of formation sand effectively.

What Factors should you Consider when Selecting Sand Control Screens?

The appropriateness and superiority of various types of sand control panels to certain wellbore applications are varied.

A balance between sand retention and impairment of production is the secret to attaining optimal performance of a sand control strategy.

You should consider the following aspects while picking a sand control screen:

  • The screen/opening size micron rating
  • Screen permissibility 
  • Distribution of particle size

How can you test the efficiency of a Sand Control Screen?

You may use sand retention tests to assess the efficiency of a sand control screen.

It’s possible to do two sand retention tests.

They comprise:

Slurry Test

The exam replicates non-conforming situations of well-being.

You are therefore suspending sand and flowing it through the screen on a slurry.

Take the particle weights created by the screen.

Also, record the pace at which the sand contacts the screen is pressurised across the screen

Sand Pack Test

This test simulates a broken borehole or a sand control complaint.

Put sand straight on the screen, then flow through the screen and sand packing with a wetting fluid.

Weigh the amount of sand that passes through the pressure drop/pressure on the display.
