ESET® - AN ENHANCED SET® SYSTEM

Increasing the operating envelope of Solid Expandable Tubulars

Ledging, highly deviated, long-reach, and equally challenging well geometries can stop conventional expandable liner runs short of the target setting depth.

Enventure, a leader in expandable technologies, developed the ESET™ system, the industry's only solid expandable liner that can be rotated and reciprocated to help operators meet their objectives, reduce non-productive time (NPT) and elevate the value of high-cost assets.

The high-torque ESET rotational liner allows you to break friction to reduce NPT and efficiently work to the targeted setting depth in highly deviated and tortuous well paths. The ESET can also be rotated once at the setting depth to improve cementation of the expandable liner ensuring the best possible cement job and effective isolation of the openhole section.

Typically, the ESET system is tripped in the hole conventionally and only begins circulation and rotation to confront ledges, dips and other wellbore tortuosity issues. Unlike a standard non-rotational SET® solid expandable liner where the progress can be halted when encountering a ledge or increased friction in tortuous extended wellbores, the ESET simply rotates across the ledge or out of the well cavity and continues toward targeted depth. Wellbore clean-up will be improved with the ability to rotate to help deliver a clean wellbore for expansion. Once at bottom rotation will help promoting a turbulent cement flow to help enhance the integrity of the cementing job and the shoe test.
