  • Patent number: 10656041
    Abstract: A distributed temperature sensing (DTS) system is operated to detect fluid leaks from a pipeline. The DTS system obtains temperature profiles from a sensing element that is deployed along the pipeline, where the profiles are temperature measurements as a function of distance. The temperature profiles are examined to identify the presence of a characteristic temperature signature expected to occur in the presence of a leak. A leak condition signal for a particular distance point is generated based on a determination that the energy of the temperature signal exceeds a threshold energy for that point.

  • Patent number: 10655442
    Abstract: Methods of performing a stimulation operation at a wellsite are disclosed. The wellsite is positioned about a subterranean formation having a wellbore therethrough and zones thereabout. The method involves establishing at least one objective for stimulating production of reservoir fluid from the subterranean formation and into the wellbore. The stimulating involves placing a stimulating fluid along the zones of the wellbore. The objective is based on wellsite data. The method also involves identifying at least one constraint for the stimulating, determining target distributions of the stimulation fluid based on the objective(s) and the constraint(s), and selecting operational parameters for the stimulating based on the constraint(s) and the target distributions. The method may also involve stimulating the subterranean formation using the target distributions and the operational parameters, monitoring the wellsite during the stimulating, and adjusting the stimulating based on the monitoring.
