Intelligent well technology is increasinly being applied to enable the reservoir to be managed effectively and the recovery factor to be maximised. Achieving excellent zonal isolation behind casing is critical when planning to produce from multiple zones, or deploy intelligent well hardware.
Achieving effective cement placement and bonding between the formation and casing can be challenging, especially in deepwater and with carbonate formations, where channelling and lost circulation are common problems.
Expro CaTS wireless communications technology transmits data and control commands using electromagnetic (EM) communications. The EM signal uses the steel construction of the well, namely casing, liner or tubing, as a signal conduit and data can be transmitted both radially and axially through pipe. Deployment options include through-tubing, externally mounted on tubing, casing or liner, or via a completion conveyed mandrel.
