Performance By The Numbers

ESS® Expandable Sand Screen

Provides One-Trip Installation, Zero Sand-Control Failures in 54 Wells

Objectives

  • Complete a shallow oil well that has sand-control issues and short pay zones.
  • Install a sand-screen system. Previous core-sample testing revealed that the field contained sand formations with high uniformity coefficients and fines percentages. These conditions made standalone screens unsuitable.

Our Approach

  • Weatherford recommended using the ESS expandable sand-screen system, which expands compliantly against the open hole. The system helps to prevent annular fines dispersal and migration and costs less per foot (meter) than conventional gravel-pack systems.
  • In a single trip, the Weatherford team deployed the ESS system to setting depth, set an EXR hanger, and expanded the screen.

Value to Customer

  • The ESS system was deployed, set, and expanded in approximately 10 hours, which is significantly less than the average installation time for a conventional gravel pack. By reducing operational time, the ESS system lowered personnel and rental-equipment costs.
  • The sand screen in the ESS system expanded compliantly to the wellbore without the need for pressure pumping services, which reduced exposure to health, safety, and environmental (HSE) risks.
  • From the end of 2002 through early 2016, Weatherford installed ESS systems in 54 of the client’s shallow-water oil wells. Since those wells came online, none have had recordable sand-control failures.
