Abstract: Methods, apparatus and systems for in-situ heating fluids with electromagnetic radiation are provided. An example tool includes a housing operable to receive a fluid flowed through a flow line and a heater positioned within the housing. The heater includes a number of tubular members configured to receive portions of the fluid and an electromagnetic heating assembly positioned around the tubular members and configured to generate electromagnetic radiation transmitted to heat the tubular members. The heated tubular members can heat the portions of the fluid to break emulsion in the fluid. Upstream the heater, the tool can include a homogenizer operable to mix the fluid to obtain a homogenous fluid and a stabilizer operable to stabilize the fluid to obtain a linear flow. Downstream the heater, the tool can include a separator operable to separate lighter components from heavier components in the fluid after the emulsion breakage.

Abstract: Current supplied to electrical submersible pumps in wells is monitored, and signal processing based on wavelet analysis and phase diagram analysis is performed on the data obtained from monitoring. An incipient malfunction of the electrical submersible pump, such as one due to scale build-up in and around the pump, can be detected at an early stage.

Abstract: An automated method and system for identifying one or more chemical tracers present in a sample drawn downstream from the well head from a produced hydrocarbon oil/water stream in a pipeline from a downhole well completion, the one or more chemical tracers having originally been applied to the outer surface of one or more lengths of tubing placed at known locations in the assembly of the downhole well completion, the chemical identification of each of the tracers and the location of each of the tracers having been retrievably recorded for the well completion in the form of a relational database, by in situ testing of a portion of the aqueous layer of the sample following settling by means of an electrophoresis analysis system that includes a micro-fluidic chip and an electronic data information collection unit and signal communication means for transmitting conditioned data from the electronic data information collection unit to the central control station for comparison with, and identification of data assoc

Abstract: Tools, processes, and systems for in-situ fluid characterization based on a thermal response of a fluid are provided. The thermal response of a downhole fluid may be measured using a downhole thermal response tool and compared with thermal responses associated with known fluids. The properties of the downhole fluid, such as heat capacity, diffusivity, and thermal conductivity, may be determined by matching the thermal response of the downhole fluid with a thermal response of a known fluid and using the properties associated with the known fluid. The composition of the downhole fluid may be determined by matching the viscosity of the downhole fluid to the viscosity of known fluid. A downhole thermal response tool for cased wellbores or wellbore sections and a downhole thermal response tool for openhole wellbores or wellbore sections are provided.

Abstract: Systems and methods of generating power in a wellbore extending through a subterranean formation are described. A swirling flow of pressurized fluid is passed through a vortex tube to generate a temperature differential between first and second outlets of the vortex tube. The temperature differential is applied to a thermoelectric generator configured to convert the temperature differential into a voltage. The thermoelectric generator produces electrical power that is transmittable to down-hole tools within the wellbore such as an inflow control valve.

Abstract: An electrical submersible pump assembly for use in a well, including a well having a high gas-to-liquid ratio has a motor, a hollow, tubular drive shaft which drives the pump, and a liquid-gas separator assembly upstream of the pump intake. The liquid-gas separator has a hollow tubular portion, which communicates with the open, lower end of the drive shaft, openings through its sidewall, and a closed lower end. The sidewall also includes at least one outwardly extending projection shaped for urging liquid contained in a liquid/gas mixture flowing towards the pump outwardly, away from the sidewall openings. Preferably, the outwardly extending projection comprises a helical blade which, using either the well casing or a separate sheath, defines a helical channel through which the oil-gas mixture flows prior to reaching the pump intake.
