Gravel packing is a sand control method used to prevent production of formation sand. In gravel pack operations, a stainless steel wire wrap screen is placed in the wellbore and the surrounding annulus packed with prepared gravel of a specific size designed to prevent the passage of formation sand. The primary objective is to stabilize the formation while causing minimal impairment to well productivity.

The gravel pack screen is packed off in an open hole section with no casing or liner to support the producing formation. The open hole interval is often prepared by underreaming a section of reservoir below the last casing shoe. When the treatment is to be applied on an existing well, a section of casing may be milled out.

It is widely accepted that a properly designed and installed, graded gravel pack will enhance a well’s efficiency and will control the migration of fine formation sand into the well. These and other value-added aspects of a gravel pack are collectively the reasons that the majority of municipal, oil and gas, industrial, and agricultural water wells are completed with gravel envelopes.

Ultimately, the gravel pack should enhance the efficiency of the well and control the migration of sand from the formation to meet the performance requirements of the project.

We are able to identify whether your well requires gravel pack services, depending on:

  1. The geographical formation of your operation
  2. If the formation sand contains large and damaging particles that could compromise the integrity of your well screen
  3. The type of gravel packing required for ultimate permeability

Whatever the application, Variperm senior engineers and field workers are continually on hand to provide technical and custom solutions needed to keep production on track
