101 Apparatus and methods for sponge coring US10649494 2003-08-27 US20040084216A1 2004-05-06 Luc Van Puymbroeck; Bob T. Wilson; Holger Stibbe; Hallvard S. Hatloy
A sponge core barrel for use in performing sponge coring and methods of assembling the sponge core barrel, as well as methods of performing sponge coring. The sponge core barrel includes an outer barrel assembly, a core bit secured to a lower end thereof, and an inner barrel assembly disposed therein. The inner barrel assembly may comprise multiple, sponge-lined inner tube sections and may also include a near-bit swivel assembly. The sponge core barrel may include a piston assembly configured to be released by contact with a core sample without imparting high compressive forces to the core. The sponge core barrel may also include a pressure compensation mechanism and, optionally, a thermal compensation mechanism cooperatively configured to maintain the pressure of pre-saturation fluid. The sponge core barrel may also include a valve assembly enabling the make-up and pre-saturation of multiple, sections of inner tube to form a single, continuous chamber.

The soil sampler includes a sampling tube having a receiving space for receiving a soil sample, the receiving space being limited in a radial direction by a wall, being open in a distal direction for permitting soil to enter and in a proximal direction being limited by a transverse wall, the transverse wall having ducts for supplying and discharge fluid to the receiving space and a plug for closing the ducts, a free plug or piston being placed in the receiving space closely fitting in there and movable between the transverse wall and the distal area of the sampling tube and the transverse wall and the free plug or piston defining a sealed chamber for fluid when the free plug or piston is situated at a distance from the transverse wall.
103 Apparatus for handling geological samples US09596401 2000-06-16 US06425447B1 2002-07-30 Pascal Bartette; Philippe Louis Cravatte
A method and apparatus for handling a geological sample, such as a core from a formation. The formation may be a formation of an oil and/or gas well. The apparatus includes a container for receiving the sample and is characterized in that the container comprises at least one wall with a surface which can change its configuration in response to pressure changes. The method of handling a geological sample obtained 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.

110 Core retainer for sidewall core tools US655844 1984-09-27 US4667753A 1987-05-26 Alfred H. Jageler
A hollow truncated cone made from material with elastic properties which expands around a core being cut from the sidewall of a borehole drilled in the earth with a core cutting means rigidly connected to a core barrel. The hollow truncated core is held in position inside the core barrel such that it does not rotate with the core cutting means during the cutting of a core.
111 Method for determining the placement of perforations in a well casing US616410 1984-06-01 US4631677A 1986-12-23 Arthur Park; Bob T. Wilson
A method for determining the productivity of a well site includes extracting a core with sponge coring techniques and measuring the parameters of the core. The parameters measured are porosity, permeability and percent mobile oil. A core factor is calculated which is the square root of the product of permeability and porosity and indicates the space available in the core for oil production. The core factor is multiplied by the percent mobile oil to provide a Production Index. The Production Index indicates the capacity of a given oil well to produce oil. With the Production Index data, perforations are selectively placed in various areas along the longitudinal axis of a well casing (38) to selectively allow communication between the interior of the well casing and a formation of interest. In this manner, only areas having high oil mobility are communicated within a given region of the formation of interest.
112 Coring device with an improved core sleeve and anti-gripping collar with a collective core catcher US537115 1983-09-29 US4566545A 1986-01-28 Arthur L. Story; Michael Filshtinsky
An improved coring device that incorporates a nonrotatable inner barrel disposed within the outer driving structure of the drill string which is coupled to the coring bit. A woven metal mesh sleeve is circumferentially mounted outside the inner barrel and tucked around its lower end. The lower end of the mesh sleeve in the inner barrel is in turn connected to a stripper tube which is pulled upwardly during the coring operation. As the core is cut by the coring bit and enters the inner barrel, the woven metal mesh sleeve is disposed about the core and constricts about the core when pulled upwardly by the stripper tube. The opposing end of the woven metal mesh sleeve is under a weight which serves to compress the metal sleeve when outside the inner barrel, thereby increasing its diameter. The plurality of wedge-shaped segments located on the top of the sleeve are collectively brought together to form a core catcher when that end of the woven metal mesh sleeve to which the segments are connected is drawn around and into the lower end of the inner barrel.

115 Apparatus for providing a packaged core US566866 1975-04-10 US3986555A 1976-10-19 William Robertson
A packaged core is obtained using a conventional core barrel system. A lining is provided in the core sample container of the core barrel. The core barrel is connected to a drill string extending into a borehole. As the drill string is rotated, the core sample moves into the sample container and inside of the lining. When the core barrel arrives at the surface, the sample core may be removed from the core barrel packaged in the lining. The core may be examined on site or the ends of the lining closed and the core completely packaged for shipment to the laboratory.

120 Sediment sample retriever US3707196D 1971-07-13 US3707196A 1972-12-26 VERVILLE WILLIAM P
A subaqueous sediment sample retriever head is affixed to the lower end of a continuous casing, which is positioned about a drill rod string and lowered onto a sampler tube, contiguous with the drill rod string. The retriever head houses in oppositely disposed cavities to a central bore, a pair of spools which store and actuate a flexible sealing slide respectively, and two pairs of spring actuated locking lugs which actuate simultaneously with the slide when the retriever head reaches the sampler tube bottom. A sleeve like follower device guides the retriever head onto the sampler tube and retains the sealing mechanism in an open position during mounting. The retriever head is advanced over the sampler by its own weight in conjunction with hydraulic jetting action.
