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.

A method for calculating the orientation of a geologic feature with respect to the axis of a wellbore drilled through earth formations. The method uses finely detailed measurements of a selected property of the earth formations made along the wall of the wellbore. The method includes the steps of segregating the finely detailed measurements by an angle subtended with respect to an arbitrary reference on the circumference of the wellbore. The measurements are further segregated into a selected axial interval along the wellbore. For each segment, for each subtended angle, the segregated measurements are spectrally analyzed with respect to spatial frequency. Coefficients of a best fit curve are determined for the phase components of the spectrally analyzed measurements with respect to the subtended angle. The orientation of the geologic feature is calculated from the best fit curve. In the preferred embodiment a noise floor is calculated in each segment by stacking the amplitude components at each spatial frequency in each interval. For each spatial frequency, the stacked amplitude is compared to the noise floor. Only spatial frequencies having amplitudes above the noise floor are used to generate the best fit curve from their respective phase components.
