Embodiment Construction

[0024] refer to figure 2 , generally indicated by 100 is an embodiment of an oil and gas well testing system. Oil and gas well testing system 100 includes a plurality of well output conduits 102 (eg, pipes) fluidly connected to a well group of N wells 101 . Although in figure 2 4 wells are shown in , but the number N of wells in a well group may vary. Wells 101 are typically clusters of wells sharing the same hydrocarbon reservoir and / or sharing the same production facility 120 . Each well output conduit 102 is suitably connected to a single well 101 so that the fluid produced by each individual well is isolated in the corresponding conduit 102 . Each well output conduit 102 is in fluid communication with one of a plurality of valves 104 (eg, a plurality of three-way valves). For reasons explained below, each valve 104 is independently configurable between a first state in which the valve fluidly connects the corresponding well output conduit 102 to the first inlet condu...

Abstract

A net oil and gas well test system for a set of oil and gas wells includes at least two net oil and gas measurement systems and a plurality of valves that are in fluid communication with the individual wells in the set and independently configurable between a first state, in which the valve routes flow to a first net oil and gas measurement system, and a second state, in which the valve routes flow to a second net oil and gas measurement system. Each net oil and gas measurement system suitably has the capability to measure a multiphase flow including oil, gas, and water without separation. For example, each measurement system can include a multiphase Coriolis meter and a water cut meter. Each measurement system suitably includes the capability to provide dynamic uncertainty estimates related to measurement of the multiphase flow.

Description

technical field [0001] The present invention relates generally to systems and methods for measuring fluids produced from oil and gas wells, and more particularly to systems and methods that use multiphase flow meters, such as multiphase Coriolis flow meters, to Measure the flow of oil, gas and water from oil and gas wells. Some aspects of the invention relate more generally to measuring multiphase fluid flow and also have uses outside the scope of the oil and gas industry. Background technique [0002] A variety of different flow meters are used in the oil and gas industry to provide information about fluids produced from oil and gas wells. One such flow meter is a Coriolis flow meter. As known to those skilled in the art, a Coriolis flow meter includes an electronic transmitter and a vibrating flow tube through which process fluid passes. The transmitter keeps the flow tube vibrating by sending drive signals to one or more drivers and performs measurement calculations ba...
