Abstract: Comparative image analysis is utilized to determine the flow rate of fluids, such as, for example, drilling fluid, completion fluid or hydrocarbons. As fluid flows through a conduit or open trough, a flow rate measurement device illuminates the surface of the fluid. Images of common surface features are then acquired at some time interval. Thereafter, the displacement of the common surface features in the images is analyzed to determine the flow rate of the fluid. Thus, non-contact flow rate measurements of opaque and non-opaque fluids are obtained.

Abstract: Systems and methods for simulating fluid properties in a production system include receiving data from a sensor. The data represents a first property of a fluid that is measured by the sensor. A second property of the fluid is estimated based at least in part on the measured first property. A third property of the fluid is calculated using the estimated second property. Calculating the third property includes running a first simulation on a first simulator and running a second simulation on a second simulator. The first and second simulations at least partially overlap in the time domain. It is then determined whether results of the first and second simulations converge to a common value.

Abstract: A well test system for testing fluids produced from one or more petroleum wells has a separator and a plurality of multiphase flow metering systems, each of which has the capability, over at least a portion of its operating envelope, of separately measuring flow rates of oil, water, and gas. The well test system has a fluidic system, including gas leg conduits coupling the separator to the multiphase flow metering systems, liquid leg conduits coupling separator to the multiphase flow metering systems, and bypass conduits for directing multiphase fluid to the multiphase flow metering systems while bypassing the separator. Valves are configured to selectively route fluid flow though the fluidic system to selectively bypass the separator when the multiphase flow metering systems can be used to provide separate flow rates of oil, water, and gas in the unseparated multiphase fluids from the well.

Abstract: A surface steerable system coupled to a drilling rig receives BHA information from a bottom hole assembly (BHA) located in a borehole. The BHA information corresponds to a first location of the BHA with respect to a target drilling path and geological formation drift information. The surface steerable system calculates a toolface vector to create a convergence path from the first location of the BHA to the target drilling path that accounts for geological formation drift defined by the geological formation drift information such that the BHA will converge with the target drilling path by drilling in accordance with the toolface vector. The surface steerable system causes at least one control parameter to be modified in order to alter a drilling direction of the BHA based on the calculated toolface vector and transmits the at least one control parameter to the drilling rig to target the BHA in accordance with the calculated toolface vector.

Abstract: An electro-acoustic system for downhole telemetry is provided herein. The system employs a series of communications nodes spaced along a string of production tubing within a wellbore. The nodes allow for wireless communication between transceivers residing within the communications nodes and a receiver at the surface. More specifically, the transceivers provide for node-to-node communication up a wellbore at high data transmission rates for data indicative of fluid flow within the production tubing adjacent gas lift valves. A method of monitoring the flow of fluid gas lift valves is also provided herein. The method uses a plurality of data transmission nodes situated along the production tubing which send signals to a receiver at the surface. The signals are then analyzed to determine gas lift valve operation and fluid flow data.

Abstract: A method for evaluating inflow or outflow in a subterranean wellbore includes acquiring first and second axially spaced pressure measurements in the wellbore. The pressure measurements may then be processed to obtain an interval density of drilling fluid between the measurement locations. A tool string including a large number of axially spaced pressure sensors (e.g., four or more or even six or more) electronically coupled with a surface processor via wired drill pipe may be used to obtain a plurality of interval densities corresponding to various wellbore intervals. The interval density may be measured during static conditions or while drilling and may be further processed to compute a density of an inflow constituent in the annulus. Changes in the computed interval density with time may be used as an indicator of either an inflow event or an outflow event.

Abstract: Methods and apparatus for measuring individual phase fractions and phase flow rates in a multiphase flow based on velocity of the flow, speed of sound through the fluid mixture, and the density of the fluid mixture. Techniques presented herein are based on measuring frictional pressure drop across a flowmeter conduit, determining a surface roughness term for the conduit during initial flow tests or through other mechanical means, implementing a correction method to balance the momentum equation, and calculating the fluid mixture density using the measured pressure drop. The techniques may be applicable to measuring flow parameters in horizontally oriented conduits and, more generally, conduits of any orientation.
