摘要： The present invention provides a system that monitors and controls the precipitation of asphaltenes in a formation fluid recovered from a subsurface formation or reservoir by using a sensor to make a direct real-time on-site measurement of the relative concentration asphaltenes from at least one location at a wellsite or in a pipeline. In a system including a fiber optic attenuated total reflectance probe for sensing asphaltenes and using a processor to compare sequential measurements, the system of the present invention can trigger the addition of additives in response to a change in asphaltene concentration in the formation fluid, preventing precipitation.

摘要： A system is provided that monitors at the wellsite injection of additives into formation fluids recovered through wellbores and controls the supply of such additives from remote locations. The selected additive is supplied from a source at the wellsite into the wellbore via a suitable supply line. A flow meter in the supply line measures the flow rate of the additive through the supply line and generates signals representative of the flow rate. A controller at the wellsite determines the flow rate from the flow meter signals and in response thereto controls the flow rate of the additive to the well. The wellsite controller interfaces with a suitable two-way communication link and transmits signals and data representative of the flow rate and other parameters to a second remote controller. The remote controller transmits command signals to the wellsite controller representative of any change desired for the flow rate.

摘要： Real time determination of the presence of emulsion in a formation fluid is accomplished using an optical probe, preferably an attenuated total reflectance probe. The determination can then be used to appropriately increase, decrease or leave unchanged the use of demulsification additives or other means to control emulsion formation. The method is particularly useful for free water knock-out separations, where a plurality of probes can be used to distinguish the location and/or volume of emulsion, or “rag”, layer and thereby to facilitate decantation of relatively pure oil and water fractions. It can also be effectively used in pipelines, and can optionally determine the degree of emulsification and trends toward emulsification or demulsification.

摘要： A system is provided that monitors at the wellsite injection of additives into formation fluids recovered through wellbores and controls the supply of such additives from remote locations. A pump supplies the selected additive from a source at the wellsite into the wellbore via a suitable supply line. A flow meter in the supply line measures the flow rate of the additive through the supply line and generates signals representative of the flow rate. A controller at the wellsite determines the flow rate from the flow meter signals and in response thereto controls the pump to control the flow rate of the additive to the well. The wellsite controller interfaces with a suitable two-way communication link and transmits signals and data representative of the flow rate, and other parameters to a second remote controller. The remote controller transmits command signals to the wellsite controller representative of any change desired for the flow rate. The wellsite controller is microprocessor based and may be programmed at the wellsite or by the remote controller to adjust the flow rate. The system of the present invention may be configured for multiple wells, with each well having a separate wellsite controller or a common wellsite controller.
