Abstract: Systems and methods presented herein include sidewall coring tools used to return core samples of rock from a sidewall of a wellbore as part of a data collection exercise for exploration and production of hydrocarbons. In particular, the systems and methods presented herein perform sidewall coring of a subterranean formation using a combination of rotary and percussive coring. More specifically, the systems and methods presented herein rotate a coring cylinder of a sidewall coring tool back and forth less than a full rotation while pushing the coring cylinder of the sidewall coring tool against a bore wall of a wellbore, and push the coring cylinder of the sidewall coring tool into the subterranean formation to enable extraction of a core sample of the subterranean formation.

Abstract: A novel corer and grinder apparatus suitable for interplanetary travel and extraplanetary operation is disclosed. The corer grinder composes a claw element attached to a shaft coupled to a motor. A second motor compresses a spring forcing against a hammer unit that constitute the majority of the unit's mass. On release the energy stored in the compressed spring converts into momentum of the hammer unit that strikes against the claw element releasing the impact energy directly to the cutting end for cutting. The direction of the energy released is modified by an impact platform to produce a horizontal chipping action to aid cutting. The claw element further comprises a pair of semi-cylindrical claw elements that separate upon rotation of the shaft in a first direction, easing collection of core samples. The semi-cylindrical claw elements join upon rotation of the shaft in the opposite direction, thereby grasping the core sample during removal from the material being sampled.

Abstract: A filter removal apparatus for removal of microporous filter membranes from multi-well filtration plate comprises a removal device and a pusher having defined therein a plurality of vertical pushpins. The pusher has a leading pushing surface to which elongated pushpins are secured each having a flat face to deliver an even pressure onto the filter membrane. The removal device comprises a stationary base plate with end wall and side walls holding a pivotal cylindrical bar which rotates in eccentric manner along its longitudinal axis. Rotation of cylindrical bar using attached handle approximately 180 degrees around the longitudinal center-line of pivot shafts causes the cylindrical bar to rotate in an eccentric motion, thus imparting a linear force to a moving plate which forces the pusher into the filter plate and causing removal of filter membranes and their flattening onto adhesive film for retention.

Abstract: A hollow cylinder (12) surrounded within the helical coil of an extricating compression spring (10) filled at its breech and sharpened at its open front end for penetrating and capturing samples of material. The assembly itself is a projectile, or is attached to a projectile (24) which conveys it to a remote sample location and imbeds it into the sample material with inertia. The assembly is held together with keeper pins (22) inserted through common holes. The imbedded core barrel (12) with its sample chamber filled with a representative sample of material extricates itself from the host matrix by means of an extricating compression spring (10) releasing its force against the surface of the host material. Once self-extricated and distanced from the sampled material it falls to the nearest horizontal surface.

The sample tool (20) has a lower end cutting edge (40). It also has handle parts (16, 18) which are connectable to the tool body (22). The handle parts are turned to cause a rotation of the tool body (22).

Abstract: A soil sampling apparatus removably mountable upon a wheeled vehicle includes a mounting frame having elongated longitudinal members adapted to adjustably extend in the direction of the length of the vehicle, and paired parallel attachment members emergent from the longitudinal members and adapted to be secured to the vehicle.

A motor slideably positioned within the center frame holds a downwardly directed auger adapted to enter the guide tube. The motor undergoes reciprocal vertical movement within the center frame by virtue of manual downward pushing and upward lifting accomplished within an operating lever.

Abstract: A soil sampling system includes a rig for driving a drive casing, a sample barrel, and sample liners simultaneously into soil to be sampled. The rig includes mechanisms for driving the casing, barrel, and lining in three modes: hydraulic hammer, continuous pressure, and vibration. The three drive mechanisms can be operated singly or in any combination. After the casing, barrel, and liners are advanced a selected depth into the soil, the barrel and liners are removed. The drive casing remains in the soil. New sample liners are put into the sample barrel, and an inner rod is attached to the sample barrel. The sample barrel is then replaced into the drive casing, and extensions are attached to the drive casing. The drive casing, including extensions, and the sample barrels, along with sample liners and inner rod, are driven further down into the soil.
