WLP - Welltec® Light Packer

For Well Construction

Introduction

The WLP (Welltec® Light Packer) is our tiered offering to the zonal isolation and well construction & integrity markets, developed specifically for less hazardous environments & lower tertiary markets, that have historically incorporated legacy swellable technology as a means for isolation.

The WLP provides a number of the benefits of our flagship WAB® (Welltec® Annular Barrier), but incorporates design & construction efficiencies that facilitates a CAPEX effective technology for marginal applications.

Overview

The Welltec Light Packer is a surface controlled, metal hydraulic expandable packer. It is mounted onto full bore liner/tubing/casing sealing off the annulus within a cased hole as well as open hole environment and forms part of the Flex-Well lower completion solution.
The WLP range offers a tiered version of the WAB (Welltec Annular Barrier) for the less demanding environments, delivering cost-effective performance across a range of operating conditions.
The WLP is more compact in sleeve length, therefore reducing overall sealing length and utilizes an optimized standard sleeve material, whilst providing consistency in open hole / cased hole seal design from the flagship WAB.
The WLP is a high grade, robust alternative to swellable technology for zonal isolation & cement assurance.
