Abstract: Method and apparatus for mitigating slug formation in a multiphase fluid stream flowing through a conduit. The method includes (a) determining the pressure in the conduit upstream of a slugging zone, (b) determining the pressure in the conduit downstream of the slugging zone, (c) determining the actual pressure difference across the slugging zone by subtracting the downstream pressure from step (b) from the upstream pressure from step (a), (d) determining the error between a target pressure difference and the actual pressure difference, (e) producing a signal having a first component which is proportional to the error and a second component which is proportional to the rate of change of the error over time, and (f) using the signal produced in step (e) to control the position of an adjustable choke valve located downstream of the slugging zone so as to stabilize variations arising in the actual pressure difference over time.

Abstract: A method of determining rate and phase of fluid produced from or injected into a hydrocarbon well includes obtaining first temperature and pressure measurements from sensors at the well. The first temperature and pressure measurements are applied to a plurality of predictive well models to calculate an estimated value of fluid rate and phase composition from each of the predictive well models responsive to the temperature and pressure measurements. A first fluid rate and phase composition result is derived from the estimate value of fluid rate and phase composition from each of the predictive well models.

Abstract: An oil field production chemical, especially a scale inhibitor, is in the form of particles thereof carrying a coating e.g. of a dispersing agent. The coating may be polymeric such as an oligomeric polyacid polyester, a polymeric alkoxylated alcohol or a fatty acid polyamine condensate or it may also be a surfactant and may be used in the form of a suspension in an inert oil, such as diesel oil or kerosene which may be injected into a subterranean formation to inhibit the formation of deposits, e.g. scale in oil wells over a longer period than compounds free of the coating.

Abstract: In some examples, the disclosure provides a method for determining a drift in clock data that is provided by a clock of a seismic sensor. The sensor is exposed to an ambient temperature that varies over time. The method includes obtaining temperature data associated with the ambient temperature as a function of time. The method also includes obtaining the clock data. The method also includes obtaining timestamp data provided by a global navigation satellite system. The method also includes determining drift data which minimizes a difference of a temporal drift in the clock data, based on the timestamp data and the temperature data. The method also includes outputting corrective data based on the determined drift data.

Abstract: A process for use in managing a hydrocarbon production system includes: selecting, from among a plurality of changes proposed to operating parameters of the hydrocarbon production system, the proposed change with the greatest estimated positive change in production; assessing whether the selected change violates an operating constraint; based on said assessment, producing a valid change based on at least the selected change or identifying the selected change as an unusable change, iterating the above steps, the iteration excluding the valid change from the plurality of proposed changes; and implementing at least one valid change, the number of implemented valid changes being less than the number of proposed changes.
