A separator for separating constituents of well fluid produced by a well is provided. The separator includes a vessel for receiving well fluid such that a first fluid constituent overlies a second fluid constituent within the vessel, a collection pipe having an opening for collecting a first fluid constituent from the vessel, and a positioner connected to the collection pipe for rotating the collection pipe about an axis to adjust a height of the opening within well fluid in the vessel. A method and system are also provided.

A system for processing oil and gas at an offshore facility includes a single stage separation module. A gas stream from the single stage separation module is pressurized in a primary compressor, and then is used to heat the incoming oil and gas upstream of the single stage separation module. Flash gas from treatment of an oil stream from the single stage separation module is pressurized in a flash gas compressor and then is used to heat glycol utilized in a gas dehydration unit. The pressurized flash gas is then commingled with the gas stream from the single stage separation module upstream of the primary compressor.

A sand separating apparatus for use with a production tubing string includes (i) a housing assembly forming an outer tubular and (ii) an inner tubular within the housing assembly to define an annular passage between the inner tubular and the housing assembly. A helical member occupies part of the annular passage below production openings in the housing assembly whereby a flow of production fluids entering from the wellbore is directed downwardly along a helical path within the annular passage as dictated by the helical member and subsequently upwardly through the inner tubular. The helical member extends radially outwardly from the inner tubular beyond a boundary surface at an outer perimeter of the annular passage to prevent formation of a gap at the tip of the helical member as it wears. A fluid passage in alignment with the helical member extends radially from inside the inner tubular to the annular passage.

Techniques for monitoring a well clean-up process are disclosed. In one embodiment, a method includes routing a multiphase fluid having oil and water to a separator of a well testing apparatus, separating the multiphase fluid into separate fluids via the separator, and routing the separated fluids away from the separator. The method also includes measuring flow rates of oil and water leaving the separator and determining individual flow rates of oil and water entering the separator as part of the multiphase fluid based on the measured flow rates of oil and water leaving the separator. Additional systems, methods, and devices are also disclosed.

A computer-implemented method for providing a performance parameter value indicative of a production performance of a first floating hydrocarbon production plant. The first plant includes hydrocarbon processing equipment and a sensor for measuring a value of a process parameter of the hydrocarbon processing equipment. The method includes obtaining first plant data from the first plant, the data including data generated by the sensor, obtaining a trained predictive model for predicting or classifying the performance parameter value, and providing, based on the trained predictive model and the first plant data, the performance parameter value for the first plant. Obtaining the trained predictive model includes obtaining plant training data from a second floating hydrocarbon production plant, the data including data generated by a sensor for measuring a process parameter value of hydrocarbon processing equipment of the second plant, providing a predictive model, and training the predictive model using the plant training data.
