Case challenge - Advanced Well Architecture

Open-hole intelligent well deployed within deep-water, pre-salt carbonate reservoir

A client offshore Brazil needed a slim-well design for an open-hole, cementless, multi-zone completion for a deep, pre-salt reservoir. Welltec’s Advanced Well Architecture (AWA) system had previously been used to enable efficient deployment of two-zone, intelligent well systems...
Case challenge - Tieback liner

Reinstating production of a shut-in well by relining and isolating corroded casing

An onshore well in Trinidad & Tobago had to be shut-in due to a corroded 6-5/8” production casing at 355 ft, and as a consequence the client had lost production ...
