Sampling Of Earth Formations Patents (Class 175/58)
  • Patent number: 9518463
    Abstract: Methods and systems for enhanced capture and recovery of core samples from unconsolidated or friable formations are provided using drilling fluids that permit increased overpressures to preserve the ability to cut core samples and to strengthen the core samples obtained. Drilling fluids used during capture and recovery of core samples may comprise a solid particulate loss prevention material having a size range from about 150 microns to about 1,000 microns. The solid particulate loss prevention material prevents fracture initiation and propagation in the subterranean formation to allow the use of higher overpressures than would otherwise be possible. Thus, by circulating drilling fluid in the borehole while drilling a core sample, higher overpressures may be achieved, which have been found to be beneficial during core capture and recovery by maintaining core integrity and avoiding core loss. In this way, core sample integrity is improved, yielding more accurate representations of the subsurface.

  • Patent number: 8538697
    Abstract: Core samples may be easily, quickly, and safely split using a fluid cutter, such as a water jet. Cutting may take place upon exit of the sample from the drill tube, or core samples may be placed in core carriers for cutting. Core samples may also be stored and transported in the core carriers. Assessment of core samples is facilitated by scanning the core samples, with the results stored to produce a virtual core sample. Virtual core samples may be displayed on a computing device, including a core sample display device which simulates the appearance of a section of an actual core.

  • Patent number: 8499856
    Abstract: The present disclosure is related to an apparatus for taking a sample in a wellbore during drilling operations. The apparatus may include a drill bit configured to form a core and at least one retractable cutter internal to the drill bit for taking the sample from the core. The apparatus may also include equipment for analyzing the sample, extracting fluid from the sample, testing fluid from the sample, encapsulating the sample, and/or tagging the sample. The present disclosure is also related to a method for taking a core sample without interrupting drilling operations. The method includes taking a core sample using a drill bit configured to take a core sample using internal cutters. The method may also include analyzing the sample, extracting fluid from the sample, analyzing fluid from the sample, encapsulating the sample, and/or tagging the sample.

  • Patent number: 8485280
    Abstract: Implementations of the present invention include a core barrel assembly having a driven latch mechanism. The driven latch mechanism can lock the core barrel assembly axially and rotationally relative to a drill string. The driven latch mechanism can include a plurality of wedge members positioned on a plurality of driving surfaces. Rotation of the drill string can cause the plurality of wedge members to wedge between an inner diameter of the drill string and the plurality of driving surfaces, thereby rotationally locking the core barrel assembly relative to the drill string. The driven latch mechanism can further include a refracted groove adapted to lock the plurality of wedge members radially within the core barrel assembly, thereby allowing for faster travel within the drill string. Implementations of the present invention also include drilling systems including such driven latch mechanisms, and methods of retrieving a core sample using such drilling systems.
