A method for retrofitting a deployable component which includes a tracer constituent within a wellbore comprises deploying the deployable component into the wellbore, and securing the deployable component at a location within the wellbore. In one example the tracer constituent is releasable from the deployable component when exposed to a trigger condition and detectable at a remote location to permit one or more parameters associated with the wellbore to be derived.

An electrical impedance tomography based flow monitoring system includes a flow accepting pipe having a cylindrical grid of m x n electrodes, wherein m is an integer greater than 3 representing a number of circumferential grid positions and n is an integer greater than 2 representing a number of axial grid positions. Each combination of adjacent circumferential grid positions and adjacent axial grid positions defines a cell having four electrodes electrically connectable in various combinations by a switch, and the switches are set to connect the electrodes into multiple axially-extending arrays. The system further comprises a controller coupled to the multiple axially-extending arrays to acquire multi-point electrical tomography measurements, wherein the controller processes the measurements to derive a monitored quantity.

Gravity surveys of subterranean formations may be based on the simultaneous measurement of gravity and its derivatives to produce a higher resolution formation map or wellbore log. For example, a method of performing a gravity survey may include positioning a matter wave interferometer relative to a subterranean formation; producing at least one cloud of atoms in the matter wave interferometer; producing a superposition of atoms in two different, spatially separated superimposed clouds from each of the at least one cloud of atoms; propagating the two different, spatially separated superimposed clouds along the matter wave interferometer as they with a gravitational field of the subterranean formation; combining the two different, spatially separated superimposed clouds with a Raman laser beam; measuring an interference produced by producing and combining the two different, spatially separated superimposed clouds; and calculating gravity for the gravitational field of the subterranean formation based on the interference.
Abstract:
Optical sensors having one or more soluble coatings thereon are used to detect the presence of a degrading fluid. In a generalized embodiment, the fiber optic sensor includes a fiber optic cable having two strain sensor positioned therein. A soluble layer is positioned over one of the strain sensor. Due to the presence of the soluble layer, the covered strain sensor optically responds differently than the other strain sensor to changes in pressure, strain and temperature. In the presence of a degrading fluid, the soluble layer degrades and ultimately dissolves, thereby changing the optical response of the previously covered strain sensor. When the soluble layer is dissolved, the strain induced by the soluble layer relaxes, thus causing a wavelength shift in the signal of the grating. By monitoring the wavelength shifts of both strain sensors, the fiber optic sensor acts as a detector for the presence of the degrading fluid.
Abstract:
An apparatus for mixing fluids within a conduit and monitoring performance of the mixing is provided. In one embodiment, the apparatus includes a conduit (12, 44) and a fluid mixer (14, 42) coupled to the conduit for mixing fluid flowing through a bore of the conduit. The apparatus also includes multiple sensors (16, 48, 50, 62, 90, 100, 112, 120, 122) for measuring a characteristic of the fluid at different locations in the bore of the conduit downstream from the fluid mixer. A controller (20, 130) of the apparatus can monitor performance of the fluid mixer in mixing the fluid flowing through the bore of the conduit based on the measured characteristic of the fluid at the different locations in the bore of the conduit downstream from the fluid mixer. Additional systems, devices, and methods are also disclosed.

An apparatus for controlling a downhole tool comprises a generator for generating electricity; a rotor connected to the generator; an electronic circuit electrically connected to the generator; a sensor for sensing movement of the rotor, the sensor being electrically connected to the electronic circuit; and a valve for wellbore fluid and for activating or deactivating a tool or function of the downhole tool, the valve being controllable by being electrically connected to the electronic circuit. The generator is configured to generate electricity to at least the electronic circuit when a flow of wellbore fluid drives the rotor. A corresponding method of controlling a downhole tool comprises configuring the electric circuit to open or close the valve depending on a variation or pattern of a flow rate, controlling the downhole tool.
Abstract:
Methods and systems are presented in this disclosure for accurate modeling of near-field formation in wellbore simulations. The approach presented herein is based on splitting a transient three-dimensional solution of finding heat and mass transfer parameters in a wellbore and a near-wellbore region into coupling modeling of a flow inside the wellbore with several transient two-dimensional solutions in the vicinity to the wellbore.
