Each type of device is associated with operational limits. Thus, a water-cut probe can measure the volumetric percentage of water in a combined oil and water flow stream. Water cut monitoring devices including microwave devices are capable of detecting water in amount up to about one hundred percent of the flow mixture, but in environments including three phase flow are subject to interpreting gas content as oil.
This interpretation occurs because microwave detection devices operate on the principle that water in the spectrum of interest absorbs sixty times more microwave energy than does crude oil. The absorption calculations assume is that no natural gas is present, but natural gas absorbs twice as much microwave radiation than does crude oil.
It follows that a microwave water cut detection system could correct the water cut reading by compensating for the fact that gas in the mixture has affected the measurement. Electrical line [] operably connects water cut monitor with controller Controller uses an electrically actuated two way valve to control pressure in liquid measurement line in a manner that assures proper operation of vortex separator in cooperation with valve , i.
Electrical line operably connects valve with controller A check valve in liquid measurement flow line assures positive flow in the direction of arrow , thus preventing intrusion of gas portion into the liquid measurement flow line The gas measurement flow line meets in a T with liquid measurement flow line to form a common discharge flow line leading to production separator Controller [] is an automation system that is used to govern the operation of system On a basic level, controller includes a computer that is programmed with data acquisition and programming software together with driver circuitry and interfaces for operation of remote devices.
The production manifold [] contains a plurality of electronically operable three way valves, e. The valves are preferably configured to each receive production fluids from a corresponding individual well, but may also receive production from a group of wells. Controller selectively configures these valves by transmitting signals on electrical line The valves are selectively configured to flow multiphase fluids from a well or combinations of wells e.
Production separator [] is connected to pressure transmitter and an electrical line for transmission of signals to controller Separator is operably connected with a gas sales line, an oil sales line, and a salt water discharge line not depicted in FIG. Operation of System [] These instructions typically reside in an electronic memory or an electronic storage device for access and use by controller Instructions that embody the process P can be stored on any machine readable medium for retrieval, interpretation and execution by controller or similar devices that are connected to system in any operable manner.
Process P [] begins with step P in which controller determines that it is proper to enter a production test mode. With regard to FIG. This determination is usually performed on the basis of a time delay, e. The test mode may also be performed on a continuous basis with the respective valves of production manifold always being selectively configured to flow into system while other valves are configured to bypass system through bypass line These types of well test measurements are conventionally used in allocating, on a deliverability basis, the percentages of the total flow stream that pass through production separator to specific production sources, e.
Manually actuated valves [] and can be opened and closed for selective isolation of system , i. An electrically actuated valve is normally closed. A second or redundant bypass line interior to valves and permits flow to bypass system when valve is open and valves and are closed. Testing begins in step P [] with controller constricting or opening valves and to reduce or increase the total flow rate through vortex separator for the purpose of separating gas from liquid phases in the multiphase fluid.
The total flow rate through system need not be reduced because controller can open valve to permit flow through interior bypass The exact flow rate depends upon the physical volume of the vortex separator and liquid measurement flow line , as well as the amount of fluid that sources and are capable of delivering to system The object of reducing the flow rate through system [] is to eliminate entrained bubbles from liquid measurement flow line through the use of vortex separator with assistance by gravity segregation while the flow rate is still high enough to prevent substantial gravity segregation of oil from water in the remaining liquid phase.
It is also possible to accomplish substantially complete separation of the gas phase from the liquid phase by increasing the flow rate with separation being accomplished by centrifugal forces through vortex separator Controller monitors the drive gain or pickoff voltage from Coriolis flowmeter for this purpose, as explained with reference to FIGS.
The log of transmissivity is plotted as a function of the frequency of alternating voltage applied to the drive coil of Coriolis flowmeter , e. The transmissivity ratio T r equals the output of meter pickoff coils divided by the drive input, i. A first curve [] corresponds to the undamped system of Equation 1 , i. A second curve corresponds to a damped system where gas is present.
The bubble enters at time and exits at time Drive gain is expressed as a percentage in FIG. Controller see also FIG. Where the drive gain or transmissivity of curve exceeds threshold , controller recognizes that density measurements are affected by the presence of transient bubbles.
Thus, Coriolis flowmeter uses only density values obtained when drive gain is less than threshold for purposes of step P The exact level of threshold depends upon the specific meter design together with the intended environment of use, and is intended to permit less than one to two percent gas by volume in the multiphase fluid. In operating Coriolis meters, it is often the case that the pickoff voltage drops in inverse proportion to the event [] of the curve shown in FIG.
The meters are sometimes programmed to sense this drop in amplitude, and they respond by vibrating an oscillation coil to an amplitude of maximum design specification until the gas damping effect is reversed. This density measurement is intended to represent density of the liquid phase having no gas voids. As an alternative to performing direct measurements on the multiphase fluid in liquid measurement line , it is also possible to obtain samples of the multiphase fluid for laboratory analysis or to approximate density measurements by the use of empirically derived fluid correlations to obtain less preferred approximations of PL.
In step P [] , controller selectively adjusts valves and in a manner that optimizes separation results in vortex separator according to manufacturer's specifications based upon the gross rates of flow through Coriolis flowmeters and together with pressure signals received from pressure transmitter and differential pressure gauge In this step, production manifold is configured to flow for active producing well test measurements. Vortex separator functions differently in this step, as compared to step P , because controller does not adjust valves and in a manner that reduces drive gain below the threshold shown in FIG.
In this circumstance, the majority liquid phase flowing through liquid measurement line may include entrained gas bubbles. Step P [] includes the use of Coriolis flowmeter to measure the total mass flow rate Q TL of the majority liquid phase including entrained gas within liquid measurement line , as well as the density of the majority liquid phase.
Gas density may be calculated from pressure and temperature information using well known correlations developed by the American Gas Association based upon gas gravity, or laboratory analysis may provide other empirical correlations for gas density determined from actual measurements of produced gas from the multiphase flow stream. Another alternative technique for the determination of gas density is to obtain an actual density measurement from Coriolis flowmeter simultaneously with step P or in a separate step P where controller selectively adjusts valves and to minimize the drive gain intensity shown in FIG.
In some situations, it is also possible to assume that the gas density remains constant because the density of gas is relatively low in comparison to the liquid density, and the assumption of a constant gas density may result in an acceptable level of error.
Equation 2 will be used in an iterative convergence algorithm. Thus, it is acceptable to begin calculations with a first guess, e. For example, a water density value may be obtained from a hydrometer connected to water trap These values may also be approximated to acceptable levels of accuracy by well known empirical correlations that are published by the American Petroleum Institute.
Step P [] is a test for convergence wherein convergence exists if the expression:. Thus, water cut meter is somewhat redundant if there is no gas phase in the multiphase flow, and may then be optionally eliminated because it is not a required value for this iterative convergence technique.
In step P [] A, a more rigorous or noniterative solution is available, provided that the measured water cut value supplied by water cut meter is within a range where the meter functions with acceptable accuracy and precision. The meter reading is a function of the fluid content, and this permits the simultaneous solution of a system of three equations to provide answers for three variables where the equations are:.
