Abstract: A method can include receiving real time data where the real time data include at least pressure sensor data from multiple pressure sensors of a hydrocarbon fluid production network for multiple locations in the hydrocarbon fluid production network; generating an expected operational region in a multidimensional domain using at least a portion of the real time data; operating a leak detection system using the expected operational region; tracking at least a portion of the real time data in the multidimensional domain; and issuing a leak detection signal responsive to the tracking indicating an excursion from the expected operational region, where the leak detection signal indicates the presence of a leak in the hydrocarbon fluid production network.

Abstract: A method can include detecting instability of multiphase fluid flow in a multiphase fluid production system using sensor measurements from the multiphase fluid production system; and, responsive to the detection of instability, increasing gas injection into the multiphase fluid production system until a variation metric of the sensor measurements decreases to a level indicative of stable multiphase fluid flow in the multiphase fluid production system.

Abstract: Method for controlling bottomhole pressure in a borehole during managed pressure drilling. In the drilling procedure fluid is circulated down a drillstring and to surface through an annulus between the drillstring and an inner-wall of the borehole. A compressor/pump is used to inject gas into the returning drilling fluid at a gas injection point. The method comprises receiving a target bottomhole pressure; determining actual bottomhole pressure during the procedure; and adjusting a variable as directed by a feedback controller, which operates to reduce the difference between the target pressure and the measured pressure. The manipulated variable may be one or any combination of: (1) pressure of drilling fluid at the entry of the fluid into the drillstring, (2) the flow rate of drilling fluid out of the drillstring into the annulus, (3) pressure of the gas exiting from the compressor, and (4) the injection rate of the gas.

Abstract: The disclosed technology is directed to methods and systems for detecting scale within a well production structure. The methods include generating a model for the well production structure. The method also includes executing a first test using the model to generate first scale data and executing a second test based on concurrently adjusting one or more of a plurality of model parameters using updated versions of synthetic or non-synthetic data to generate a plurality of second scale data. The method also includes executing a merging operation between scale data realizations comprised in the plurality of the second scale data to generate scaling signature data. The method further includes initiating generation of one or more of: a scale data visualization, or an intervention report, or an intervention signal for a control operation that mitigates against detected scale.
