Abstract: Aqueous liquid which has been in contact with a subterranean geological formation, especially a hydrocarbon reservoir, is examined in order to detect or measure viscosifying polymer therein, by flowing a sample of the liquid through a constriction thereby causing extensional flow and alignment of any polymer molecules with the flow, and examining the solution for birefringence of aligned polymer molecules. The amount of birefringence is determined from intensity of light which has passed through the solution relative to intensity of the light source.

Abstract: The system for measuring multi-phase fluid flow characteristics is an on-site system for measuring and calculating fluid density of a multi-phase fluid, such as a mixture of oil and water, as well as a water cut thereof. The system for measuring multi-phase fluid flow characteristics includes a conduit having a lower inlet and an upper outlet. The lower inlet is adapted for direct connection to an oil pipeline, an oil well, or the like for receiving the multi-phase fluid flowing therethrough. The conduit defines a pressure monitoring portion having opposing ends. First and second impulse lines connect first and second gauge pressure transmitters and a differential pressure transmitter to the opposing ends to measure total pressure drop and frictional pressure differential to an external controller, which calculates the fluid density and the water cut therefrom The system may also include temperature and volumetric flow rate sensors.

Abstract: A system for automated collection of cutting samples produced during the drilling of a well includes an automated valve system for periodically collecting samples including fluid and cuttings from a flow line from a drilling rig and a packaging system for packaging each sample collected from the flow line. The packaging system deposits each sample received from the valve system at a corresponding point along a moving elongated strip of base material, covers the elongated strip of base material and samples deposited on the base material with a strip of cover material, and advances the covered elongated strip of base material and covered samples onto a reel.

Abstract: An oil well production analyzing system receives production fluid samples from the oil well according to an automated sampling schedule. The fluid samples are taken from a pipeline through a sampling apparatus to obtain a representative sample. The representative sample flows into a circulation loop having a circulating pump, a water cut analyzer, and a cylindrical vessel, with interconnecting piping and actuated valves there between, with the actuated valves and the circulating pump controlled by a digital processor. Once a determination of the percentage of water and oil in the sample has been determined, the processor stops the circulating pump and activates a piston in the cylindrical vessel which sweeps the cylindrical vessel of any fluid contained in the vessel in preparation of receiving a subsequent fluid sample from the oil well.
