Halliburton has introduced IntelliTTCE, a through-tubing cement evaluation service aimed at offshore plug and abandonment (P&A) work, Drilling Contractor reports. The launch is framed around early P&A planning: the company says the service is designed to help operators verify zonal isolation before abandonment operations begin. Its central feature is the ability to evaluate cement condition while the tubing remains in the well, rather than after it has been pulled.
In conventional workflows, according to the company, insight into cement condition often arrives late — after tubing has been removed and a rig has been mobilized to the well. Halliburton frames IntelliTTCE as a way to move that assessment earlier in the process, presenting the delayed timing as the limitation the service is meant to address. By evaluating the cement through the tubing, the service is intended to give operators information about zonal isolation before those steps are taken.
On the technical side, the company describes IntelliTTCE as combining two independent deterministic evaluation methods within its through-tubing assessment. Because the measurements are made through the tubing, the cement can be characterized with the string still in the well. The company positions the service as a pre-abandonment check rather than a step performed during the P&A operation itself.
For operators, the significance lies in timing. Cement information that in a conventional sequence waits for tubing removal and rig mobilization would, under the company's description, be available during early P&A planning instead. That would let zonal isolation be verified while abandonment plans are still being shaped, before the tubing comes out and a rig is mobilized.
