  • Patent number: 9766365
    Abstract: A method for making downhole electromagnetic logging while drilling measurements includes rotating an electromagnetic logging while drilling tool in a subterranean wellbore. The logging tool includes first and second transmitters, each of which includes a tilted antenna, and a receiver axially spaced apart from one another. Electromagnetic voltage measurements are made at the receiver while the tilted transmitting antenna in the first transmitter fires during tool rotation. The electromagnetic voltage measurements are mathematically rotated through at least the arbitrary angle to obtain rotated measurements, selected ratios of which are processing to compute gain compensated measurement quantities.

  • Patent number: 9726013
    Abstract: A no purge sampler for collecting fluid samples includes a flexible tube having a sealed first end and a second end, the tube defining an interior cavity, a check valve disposed at the second end of the tube, and at least one aperture above the check valve. To collect fluid samples, the no purge sampler is lowered into the fluid to be sampled. The at least one aperture streamlines the tube as it is lowered into the fluid reducing drag-down and mixing. Once the sampler reaches the desired depth, the sampler is pulled upwards allowing fluid to enter the interior cavity. The sampler is then pulled out of the fluid without losing any of the fluid in the interior cavity of the tube or contaminating the sample with any extraneous fluid.

    Abstract: A downhole tool is conveyed within a borehole extending into a subterranean formation. A void is created in a sidewall of the borehole by extending a rotating member from the downhole tool into the sidewall. A portion of the sidewall surrounding the void is mechanically compressed, and the viscosity of hydrocarbons in the subterranean formation proximate the void is reduced by injecting a fluid from the downhole tool into the formation via the void. Fluid comprising the reduced viscosity hydrocarbons and the injected fluid may then be drawn from the subterranean formation into the downhole tool.

  • Patent number: 9488030
    Abstract: A pressure compensation system for enclosed spaces at a subterranean location changes volume with thermally induced solubility changes of a salt in water. The salt is held in an enclosure that is either rigid, or impervious and flexible or porous and flexible. As well conditions change and temperature increases, some of the salt goes into solution with a resulting decrease in volume that compensates for thermally induced volume increase due to temperature increase in the borehole. Conversely, a decrease in borehole temperature brings some of the salt out of solution for a volume increase to offset the volume decrease of the adjacent fluid to keep the pressure stabilized in the enclosed volume. In the porous enclosure embodiment the openings are sufficiently small to retain the salt even in solution. However, minimal net flows are anticipated for pressure compensation due to changing thermal effects.

  • Publication number: 20140157883
    Abstract: Flowline pressure equalizer systems, methods and/or apparatuses for use on a downhole tool are provided. A pressure equalizer may be provided in communication with two flowlines. The pressure equalizer may use equalizing chambers and equalizing pistons to regulate pressure in one or both flowlines. Further, one or more flow routing modules may be interchangeable to further alter the flow scheme between the flowlines. Different plugs may house various flow routing configurations such that the plugs may be installed and/or removed in the tool string automatically or by a user.

  • Publication number: 20140144625
    Abstract: A technique involves collecting formation fluids through a single packer. The single packer comprises an outer bladder with drains positioned in the outer bladder to obtain formation fluid samples. Features also may be incorporated into the single packer to limit sealing in the circumferential spaces between the drains and to provide a larger sampling surface than provided simply via the drain surface area.

  • Patent number: 8708049
    Abstract: Methods and devices for mixing a first fluid with a second fluid downhole include a chamber having a first end, a second end and an opening for fluid to flow there through. A top surface of a perforated piston is capable of contacting the second end and a top surface of a piston is capable of contacting a bottom surface of the perforated piston. The perforated piston is located at a first position within the chamber based upon characteristics of a first fluid. A first fluid delivery system supplies the first fluid and a second fluid delivery system supplies a second fluid to the chamber, wherein the second fluid is at a pressure that moves the piston approximate to the first end. An actuating device applies a force against the bottom surface of the piston to inject the fluids through channels of the perforated piston to produce spray droplets.

  • Patent number: 8646523
    Abstract: Porous objects, such as porous balls, may be employed within telescoping devices to control proppant flowback through a completed well during production. The telescoping devices may connect a reservoir face to a production liner without perforating. Acid-soluble plugs initially disposed within the telescoping devices may provide enough resistance to enable the telescoping devices to extend out from the production liner under hydraulic pressure. The plugs may then be dissolved in an acidic solution, which may also be used as the hydraulic extension fluid. After the plugs are substantially removed from the telescoping devices, the reservoir may be hydraulically fractured using standard fracturing processes. The porous balls may then be inserted into the telescoping devices to block proppant used in the fracturing process from flowing out of the reservoir with the production fluids.

  • Publication number: 20140027112
    Abstract: A method of measuring parameters of a formation along multiple axes is disclosed. A formation tester tool is introduced into a wellbore. The formation tester tool includes a first probe oriented at an angle from a second probe about an axis of the formation tester tool. The first and second probes are positioned against a surface of the wellbore. Fluid is injected via at least one of the first and second probes. Pressure parameters corresponding to the fluid injected into the formation are monitored. Formation stresses about the formation fractures along multiple axes are determined based, at least in part, on the pressure parameters.
