The present invention is directed to a system and method for measuring water content or water cut in fluids and in a petroleum/gas-water mixture. Specifically, the invention relates to a system and method to be used in oil production facilities where fluids extracted from the subsurface exhibit characteristics of hydrocarbon-water mixtures with variable salinity levels.
The present invention relates to a system for monitoring producing and/or injecting wells in enhanced oil recovery processes, wherein the system enables continuous monitoring of downhole pressure and temperature, with the information being transmitted in real-time via telemetry and/or stored in memory for long-term logging.
The present invention is related to a mechanism to improve the operation of the valves regulating the flow of injection water, located at the bottom of the water injection wells; which are affected in their operation by high injection pressures and are damaged by the permanent and continuous closing and opening action. Since the principle of its operation is based on the movement of a stem, whose base sits against a seat or chair, which blocks the flow of water, by closing and opening continuously through the action of a spring.
This invention is related to the technology for measuring water quality through multiple parameters that are required to identify that aqueous solutions from hydrocarbon discharges, treatment plants and wastewater, among others, meet the requirements required for prevent contamination and maintain strict control in other processes where these water sources are used. For this purpose, not only are the parameters measured on site through sensors specially manufactured and conditioned for these environments, but the information is processed and transmitted in real time for local and remote storage and management through the Internet, allowing the control of these online processes. Likewise, the sensors and the respective electronics are installed in an encapsulation made of special very low friction material type R2C(OR’)2 that prevents the adhesion of hydrocarbons and other substances that can affect the reading and allows the sensors and electronics to be submerged. up to at least 10 meters deep ensuring adequate measurement of water quality in multiple conditions.
This invention describes a sensor for the measurement of suspended solids in water, based on transmittance and back-dispersion techniques, designed for the measurement of suspended solids in waters with the presence of hydrocarbons and mixtures of water and other fluids. The sensor comprises sources and receivers of electromagnetic radiation, a mechanical system or polymer encapsulation with a low coefficient of friction, an electronic processing and control system that delivers a voltage output proportional to the concentration of solids suspended in water and a system of electrical power of the system based on rechargeable batteries and energy sources such as solar panels, wind generators or industrial electrical networks.

Integration of hardware
and software to optimize
the real time monitoring
for digital oil fields.
Transducers/process automation, real time acquisition and remote monitoring have been in
the oil industry for many years, at least from late 1980 decade (I worked with data transmission
via telephone line modem in 1989 in Venezuela and full remote logging/data transmission via
satellite in 1996 in Egypt).
Design and Implementation of a High Sensitivity Differential Pressure Sensor for Petrophysical Applications.
A capacitive differential pressure sensor has been developed with a resolution range of 0.1 PSI. The main field of application is hot hydrodynamic flow measurements in oil production and exploration wells. In these environments with complex operating conditions, the sensor must operate continuously and without failures at pressures of up to 18,000 PSI and temperatures of up to 180°C.
Design and Implementation of Inline and Fullbore Flow Measurement System Applied in Oil Production and Exploration.
The measurement of flow in oil production and exploration is a fundamental factor for evaluating production parameters and well characteristics. In Colombia, flow rate measurement is still not fully regulated, and measurement errors of around 20% are estimated.
Oil In Water Quality Monitoring In Real Time: Applications For Produced Water: Disposal And Re-injection Case Studies
The present paper introduces an integrated equipment system developed and patented jointly with Ecopetrol to monitor in real time water quality parameters for produced water from mature fields. This paper includes equipment details starting from electronics to the description of a special package developed to detect suspended oil in water. The field implementation meant a new and more cost-effective manner to not only monitor water quality but also to improve operation sequences in treatment plants. Monitoring process is necessary to control the quality from production and processing water plants consideringthe importance of keeping all the parameters within the limits established by regulations or recommendations,including the volume of suspended oil in water.
