| 81 | A coring device with an improved core sleeve and anti-gripping collar | EP84110592.7 | 1984-09-06 | EP0134581A1 | 1985-03-20 | Rowley, David S.; Aumann, James T. |
An improved coring device tnat incorporates a nonrotatable inner barrel (50) disposed within the outer driving structure (12) of the drill string which is coupled to a coring bit (30). A woven metal mesh sleeve (105) ist circumferentially mounted outside the inner barrel (50) an tucked around its lower end (112). The lower end (110) of the mesh sleeve (105) in the inner barrel (50) is in turn connected to a stripper tube (40) which is pulled upwardly during the coring operation. As the core is cut by the coring bit (30) and enters the inner barrel (50), the woven metal mesh sleeve (105) is disposed about the core and constricts about the core when pulled upwardly by the stripper tube (40). The opposing end of the woven metal mesh sleeve (105) is connected to a weight (125) which serves to compress the metal sleeve (105) when outside the inner barrel (50), thereby increasing its diameter to prevent binding or jamming. |

An apparatus for handling a geological sample, such as a core from a formation is described. The formation may be a formation of an oil and/or gas well. The apparatus includes a container for receiving the sample and is characterised in that the container comprises at least one wall with a surface which can change its configuration in response to pressure changes. A method of handling a geological sample obtained from a formation is also described and includes providing a container for receiving the sample. The container has a surface which is capable of changing its configuration in response to pressure changes. The sample is introduced into the container, and the configuration of the surface is changed to contact the sample. The container is then withdrawn from the formation. |

| Values for porosity and permeability of core samples in a borehole are estimated by generating radial waves with an acoustic source in fluid around the core sample, and measuring pressure in the fluid. Moreover, the acoustic source operates at frequency close to a resonant frequency of the core sample. After the acoustic source no longer operates at the resonant frequency, pressure in the fluid attenuates over time. The pressure attenuation is recorded by the pressure measurements, along with the pressure in the fluid at the first harmonic (spectral component). The pressure attenuation and spectral component each are dependent on porosity and permeability of the core sample. Thus values for the porosity and permeability are determined based on the arithmetic relationships between pressure attenuation and the spectral component and porosity and permeability. | ||||||
