Apparatus and methods for performing optical analyses in a harsh environment are disclosed. Some of the systems and methods of the present disclosure include fluorescence, absorption, and reflectance detection using a drum spectrometer. Other systems and methods of the present disclosure include a measurement channel and a parallel reference channel concurrently filtering optical signals.

Optical fluid analyzer

Methods and systems for measuring neutron sigma of downhole reservoir as a function of time for a predetermined testing volume are disclosed. The methods and systems of the present invention analyze the testing volume while maintaining the formation in the testing volume in an unchanged and undamaged state and while dynamically flowing fluids in and out of the testing volume. The systems and methods of the present invention are especially important in determining petrophysical information about the reservoir as well as the in-situ effect of substances on enhanced oil recovery.

Systems and methods for monitoring changes in a formation while dynamically flowing fluids

Methods and systems for collecting high quality reservoir samples and determining producibility of those samples are disclosed that provide for a non-stop and no shock sampling process. The systems and methods of the present disclosure are especially important collecting samples of reservoir samples in a manner that most closely resembles production fluids and maintains the reservoir at or near the draw down pressure during the pumping and sampling processes.

Apparatus and methods for tools for collecting high quality reservoir samples

Methods and systems for delivering EOR substances and determining their efficiency in real time, or near real time, are disclosed. The systems and methods of the present disclosure are especially important in determining petrophysical information about the reservoir as well as the in-situ effect of substances on enhanced oil recovery.

Apparatus and methods for evaluating formations

A method of analyzing crude oil that may include the step of contacting the crude oil with an ionic liquid to form a treated sample. The method may further include determining presence of NAD in the treated sample.

Methods and apparatus for extraction of NAD and proteins from crude oil and gas, drill cuttings, cores and other hydrocarbons and organics for unique spectral identification

Methods, apparatus and products for separating oil and mud filtrate down hole and production of each to the surface via separate tubing, that includes custom engineered drill pipe for which two types of openings called ports have been cut or drilled: production ports and isolation ports. The production port produces formation fluid (normally hydrocarbons) from a perforation. In one non-limiting embodiment, a tube is welded to the inside of the casing at each production port to transmit the formation fluid to the top of the drill pipe section where it is attached to a custom engineered casing collar (described below) designed to allow flow to the next drill pipe section of the device. The isolation port produces mud filtrate from the adjacent borehole wall exterior to the casing, and these isolation ports are arranged in a pattern around each production port to keep mud filtrate in the invaded zone from reaching the production port. The number and placement of the production ports as well as the number, placement and shape of the isolation ports are determined using the information regarding the perforating design and other information such as the filtrate type and estimates of invasion depth as determined by well logs. Packers are set above and below the apparatus to provide an 'isolation' chamber to contain the produced filtrate. Tubing through the upper packer will produce the filtrate to the surface via differential pressure or pumping. After the casing has been cemented, the perforating guns in the production ports are fired to begin production of formation fluid.

Methods, apparatus and products for production of fluids from subterranean formations

This invention relates to a measurement tool and method of use, and in particular to a measurement tool for use in determining a parameter of a stationary or moving fluid. The measurement tool has been designed primarily for use in borehole formation testing. The measurement tool can measure the dielectric constant of a fluid within a pipe or surrounding the tool. The pipe or wall between the tool and the fluid is electrically insulating. The tool has pair of capacitor plates mounted adjacent to the pipe or wall, a signal generator which can deliver an alternating electrical signal to at least one of the capacitor plates, and a detector for measuring a signal dependent upon the electrical capacitance between the capacitor plates. The measurement tool can additionally measure the electrical resistivity of the fluid.

Measurement tool and method of use

A multi-channel detector assembly for downhole spectroscopy has a reference detector unit optically coupled to a reference channel of a source and has a measurement detector unit optically coupled to a measurement channel of the source. The reference and measurement detectors detect spectral signals across a spectral range of wavelengths from the reference and measurement channels. Conversion circuitry converts the detected spectral signals into reference signals and measurement signals, and control circuitry processes the reference and measurements signals based on a form of encoding used by the source. Then, the control circuitry can control the output of spectral signals from the source based on the processed signals or scale the measurement signal to correct for source fluctuations or changes in environmental conditions.

Multi-channel detector assembly for downhole spectroscopy

A refractive index sensor having one or more sources, an adaptive optical element or scanner, imaging optics, a sensing optic, and one or more detectors. The scanner impinges a signal from the source into the sensing optic and onto a sensor-sample interface at sequential angles of incidence. The detector response increases dramatically to signals reflected from the interface at corresponding sequential angles of reflection equal to or greater than a critical angle. The refractive index sensor also uses an input lens between the scanner and the sensing optic and uses an output lens between the sensing optic and the detector. A processor controls the sensor and can determine index of refraction of the fluid sample based on the detector response and scan rate. The sensor can be used in several operational environments from a laboratory to a downhole tool, such as a formation tester to determine properties in a borehole environment.

Refractive index sensor for fluid analysis

A multi-channel source assembly for downhole spectroscopy has individual sources that generate optical signals across a spectral range of wavelengths. A combining assembly optically combines the generated signals into a combined signal and a routing assembly that splits the combined signal into a reference channel and a measurement channel. Control circuitry electrically coupled to the sources modulates each of the sources at unique or independent frequencies during operation.

Multi-channel source assembly for downhole spectroscopy

A downhole fluid analysis tool has a tool housing and a fluid analysis device. The tool housing is deployable downhole and has at least one flow passage for a fluid sample. The fluid analysis device is disposed in the tool housing relative to the flow passage. Inside the device, one or more sources generate a combined input electromagnetic signal across a spectrum of wavelengths, and a routing assembly routes generated signals into the reference and measurement signals. At least one wheel having a plurality of filters is rotated to selectively interpose one or more of the filters in the paths of the reference and measurement signals.

Filter wheel assembly for downhole spectroscopy

A downhole fluid analysis tool has a housing and a flow passage for downhole fluid. A device disposed in the tool housing relative to the flow passage has a one or more sources, one or more sensing optics, one or more detectors, and control circuitry. The source generates an input signal. The sensing optic has a refractive index (RI) higher than crude oil and other expected constituents. A sensing surface of the optic optically coupled to the source interfaces with a downhole fluid. When the variable RI of the downhole fluid reaches a defined relationship to the optic's RI, the input signal interacting with the sensing surface experiences total internal reflection, and the reflected signal from the sensing surface remains in the sensing optic and reflects to a detector. The control circuitry monitors the detector's response and indicates gas break out if the response is above a threshold.

Downhole gas breakout sensor

This invention relates to a measurement tool, and in particular to a measurement tool for use in determining the density and/or viscosity of a stationary or moving fluid. The measurement tool has been designed for use in borehole applications during the location and exploitation of oil and gas reserves. The measurement tool has a resilient pipe with a substantially uniform cross-section along its length, and the fluid is located within the pipe. The pipe carries an exciter which is connected to a signal generator, the exciter and signal generator being adapted to impart transverse and/or rotational oscillations to the pipe. Measuring the frequency of the oscillations can be used to determine the density and/or the viscosity of the fluid within the pipe.
