  • Publication number: 20180073352
    Abstract: Methods may include recording pressure and/or temperature data at two or more time points in a region adjacent an isolated zone in a wellbore created by one or more isolation devices; and determining the degree of fluid communication around the one or more isolation devices from characteristic changes in the recorded pressure and/or temperature data. Methods may also include injecting a fluid into an isolated zone in a wellbore created by one or more isolation devices; recording pressure and/or temperature data at two or more time points in a region adjacent the isolated zone; and determining the degree of fluid communication around the one or more isolation devices from characteristic changes in the recorded pressure and/or temperature data.

  • Publication number: 20170002622
    Abstract: Cement placement simulations and post-placement simulations are traditionally performed before the cementing operation takes place. Several simulation iterations may be performed, allowing engineers to develop an optimal cement treatment design. When the cementing operation takes place, engineers may follow the procedure prescribed by the simulator. After the operation is complete and the cement has set, logging operations may be performed to verify that the goals of the cementing operation have been met. Monitoring the progress of the cementing operation in real time allows a determination of whether cementing events are unfolding as predicted by the simulator. If deviations from the plan occur, some real-time adjustments may be made to improve cementing results.
