Abstract: Temperature data collected from a distributed temperature sensing system may be used to prepare a temporal thermal profile of the wellbore. The temporal thermal profile may be used to determine a generalized heat transfer coefficient (k) and/or a generalized geothermal profile (Tae). The temporal thermal profile and the generalized heat transfer coefficient (k) and/or the generalized geothermal profile (Tae) may be used to estimate thermal properties of a wellbore, such as well as fluid and flow characteristics. A heat of hydration index may also be determined based on the temporal thermal profile.

Abstract: A method for controlling, tailoring, monitoring and executing a pumping operation of a wellbore treatment into a wellbore with an advisory process accessing pumping simulation results from a pumping model group. The advisory process can determine a change in the wellbore environment by comparing periodic datasets indicative of a pumping operation to a set of operational threshold values. The advisory process can identify the change in the wellbore environment from pumping simulation results generated by a pumping model group with pumping model inputs comprising portions of the periodic datasets. The advisory process can generate a modified pumping procedure in response to the identification of the change in the wellbore environment. The pumping model group can generate and forecast a probability of the pumping operation achieving a job objective.
