Abstract
A method includes attaching a fiber optic cable to a cementing tool configured to attach to a cementing plug displace cement in a hydrocarbon well. The method can also include deploying the cementing tool in the hydrocarbon well to cause the cementing plug to begin releasing cement to form to displace cement to form a cement sheath in the hydrocarbon well. Additionally, the method can also include receiving, by a sensor receiver at a wellhead of the hydrocarbon well, a signal with cementing data as the cement sheath cures. Furthermore, the method can also include determining whether the cement sheath is curing properly. A system and a non-transitory computer readable medium are also provided.
