Retaining Fluid Or Taking Separate Fluid Sample Patents (Class 175/59)
  • Patent number: 10480316
    Abstract: The present disclosure relates to methods and apparatus for determining a viscosity-pressure profile of downhole fluid by measuring the viscosity at several different pressures during a sampling operation. According to certain embodiments, the viscosity may be measured at different times during a sampling operation and used to generate the viscosity-pressure profile. For example, the viscosity may be measured at the beginning of pumping, during filling of a sample chamber, during a pressure-build up period, and while retracting the probe. The measured viscosities may then be employed to determine a profile that represents the change in viscosity that occurs with pressure.

    Abstract: The present invention relates to an oil-pressure type fixed piston sampler for sampling a soil sample for site investigation. The oil-pressure type fixed piston sampler comprises a sampling unit (12) and an oil-pressure controller (14). Here, when the sampling unit (12) inserted into a drilled hole and a movable piston (80) moves downward, a sampling tube (1) moves downward to take a sample. The oil-pressure controller (14) connected with the sampling unit (12) controls oil pressure to cause the movable piston (80) to shift vertically. The sampling unit (12) comprises an upper head (20), a lower head (40), a piston housing (70), a rod block (100), a movable rod (90), a fixed piston (110), a fixed rod (92) and a separation rod (94). Since the sampling tube (1) takes a sample by a piston indentation method, high-quality, undisturbed samples can be obtained.

The fluid pressure in the coiled tubing string is then increased, which pressurizes the fluid sample in the chamber (92). Thereafter, the coiled tubing and the fluid sampler (50) are retrieved to the surface with the pressurized fluid sample remaining above its saturation pressure during collection and retrieval to the surface.

  • Patent number: 7934569
    Abstract: A method of stabilizing a core sample is described, and an agent for use in the stabilising method. The method involves injecting a foam around a core sample in a cylindrical liner. The foam comprises mixture of a first pressurized polymerisable-based fluid and a second pressurized fluid, which are simultaneously injected as a foam into an annulus between the core sample and liner. The foam preserves the sample and cushions it for transportation. The foam can include a dye or colorant to distinguish the foam from other materials in the core sample.

  • Patent number: 7878244
    Abstract: Apparatus and methods to perform focused sampling of reservoir fluid are described. An example method couples a sampling probe to a subterranean formation and, while the sampling probe is coupled to the subterranean formation, varies a pumping ratio of at least two displacement units to reduce a contamination level of a formation flu id extracted via the sampling probe from the subterranean formation.

  • Patent number: 7874356
    Abstract: A technique involves collecting formation fluids through a single packer having a plurality of sample collectors disposed along an expandable packer element. An anti-expansion device also is deployed along the expandable packer element to limit expansion in localized regions. Limiting the expansion can provide additional space or an increased production surface that facilitates collection of samples.

  • Patent number: 7841406
    Abstract: A fluid sampling system retrieves a formation fluid sample from a formation surrounding a wellbore extending along a wellbore axis, wherein the formation has a virgin fluid and a contaminated fluid therein. The system includes a sample inlet, a first guard inlet positioned adjacent to the sample inlet and spaced from the sample inlet in a first direction along the wellbore axis, and a second guard inlet positioned adjacent to the sample inlet and spaced from the sample inlet in a second, opposite direction along the wellbore axis. At least one cleanup flowline is fluidly connected to the first and second guard inlets for passing contaminated fluid, and an evaluation flowline is fluidly connected to the sample inlet for collecting virgin fluid.

  • Patent number: 7762328
    Abstract: A sampling tool for retrieving one or more samples from a wellbore drilled in a subterranean formation includes a coring device retrieving a core from a wellbore wall, wellbore isolation devices that isolate an annular region proximate to the coring device; and a flow device that flows fluid out of the isolated region. During operation, the sampling tool is positioned adjacent a formation of interest. The isolation device is activated to isolate an annular region proximate to the sampling tool. Decentralizing arms can be used to position the coring device next to the wellbore wall. Thereafter, the flow device flows fluid out of the isolated annular region. When the isolated region includes mostly formation fluid, the coring device is activated to retrieve a core from a wall of the wellbore in the isolated annular region and store it in formation fluid.
