| 224 | Boring apparatus | US10450066 | 2004-03-15 | US20040144566A1 | 2004-07-29 | Hugh Edward Fisher |
| An apparatus (10) for use in boring is described, the apparatus including a rotatable drive shaft (12), a cam member (20) and followers (16) for converting rotational motion into reciprocal motion, and a shroud (24) having a cutting edge (26) driven by the cam member and followers. The shroud may be selectively engageable with the cam member and followers, allowing the drive shaft to be removed through the shroud. A fluid circulation arrangement (31), (13) allows air to be injected into loose drilling substrate, so assisting removal of drill cuttings from the boring apparatus. Also described is a drill string incorporating a similar arrangement, allowing the drill string to be reciprocated within a bore. The drill string may further include casing sections, which may have intumescent coatings to allow the sections to be fixed in a wellbore. | ||||||
| 225 | Air delivery system for a direct push drilling swivel | US10235556 | 2002-09-06 | US06763901B1 | 2004-07-20 | Lorraine M. LaFreniere; David H. Surgnier |
| A power swivel provides the rotational force to drill consolidated subsurface strata while an unrestricted airflow through the swivel and down a drill string remove cuttings from the borehole. The power swivel is configured to mount on direct push equipment, such as a cone penetrometer, to eliminate the need for a conventional drilling rig when a consolidated layer is encountered during direct push operations. A drilling nipple and pack-off are provided near the surface to maintain the air flow during drilling and to direct the cuttings to a desired location. Also, a dual-valved air delivery system provides safe, remote-controlled air flow to the swivel. | ||||||

| 227 | Roof bit body and insert assembly | US09888770 | 2001-06-25 | US06684968B2 | 2004-02-03 | Douglas E. Bise; Phillip W. Haga; Ted R. Massa |
| A center vacuum rotary drill bit including a rotary drill bit body and an insert. The bottom surface of the slot has a projecting key that cooperates with a depression keyway of the insert. Generally vertical sidewall surfaces of a depression keyway and vertical surfaces of a projection key provide mechanical resistance against lateral movement of the cutting insert. This mechanical resistance reduces displacement of the insert with respect to the bit body during brazing and thus a high quality, accurately aligned drill bit assembly is provided by applicants' invention. The depression keyway is designed so as to minimize the effect of the axial load on the insert by avoiding sharp corners which tend to amplify nominal stress and provides an insert of a proper carbide density after pressing. Integral bit body protuberances adequately separate the insert within the slot and permit braze flow between the insert and slot. The protuberances enhance braze flow when braze is fed between the insert body and bit body. | ||||||

| A system for unloading fluids from a generally upright tubular member of a wellbore wherein a combustible fuel cell can be placed in the tubular member below the fluid and ignited to generate gasses. The gasses generated by the burning of the fuel cell can be used to force at least a portion of the fluid upward out of the tubular member. | ||||||
| 229 | Portable seismic shothole drilling system | US09561768 | 2000-04-29 | US06540034B1 | 2003-04-01 | Noel Evan Browne; Gerard Thomas Pittard |
| A portable apparatus for creating holes in rock. A rock drill connected to a compressed air supply is engaged with a connector attached between the rock drill and a rock bit. The connector has a substantially tubular shaft for transporting compressed air from the air supply to the rock bit. The tubular shaft uniquely maximizes the air available for removing rock cuttings and minimizes the possibility of rock bit sticking in the rock hole. The invention is particularly suited to seismic shothole drilling requiring portable equipment operable by a single person. | ||||||

| A method of removing formation damage through the controlled injection of fluids into the formation, followed by a controlled sudden release of pressure in the formation, an under-balanced surge, which causes fluid and damaging materials to flow back into the well bore. This method is most effective when repeated more than once. | ||||||

| A drill bit assembly includes a driver adapted for attachment to a down hole pneumatic hammer. A pilot bit is coupled to the driver in a manner permitting rotational and axial movement between driver and pilot bit. A series of underreamer arms are disposed intermediate the driver and the pilot bit and engage a centrally disposed cam block on the pilot bit. Pivot pins of the underreamer arms are journaled in and move with the driver during partial rotation of the driver during arm deployment and retraction. Passageways in the driver and pilot bit direct compressed air to the working surface of the bit for discharging particles upwardly through channels in the bit and driver. Inclined surfaces on the underreaming arms cooperate with the lower end of a casing to contribute to are retraction prior to removal of the assembly through the casing. | ||||||

| 237 | Casingless down-hole for sealing an ablation volume and obtaining a sample for analysis | US283079 | 1994-07-29 | US5561516A | 1996-10-01 | Donald T. Noble; Steven D. Braymen; Marvin S. Anderson |
| A casing-less down hole sampling system for acquiring a subsurface sample for analysis using an inductively coupled plasma system is disclosed. The system includes a probe which is pushed into the formation to be analyzed using a hydraulic ram system. The probe includes a detachable tip member which has a soil point mad a barb, with the soil point aiding the penetration of the earth, and the barb causing the tip member to disengage from the probe and remain in the formation when the probe is pulled up. The probe is forced into the formation to be tested, and then pulled up slightly, to disengage the tip member and expose a column of the subsurface formation to be tested. An instrumentation tube mounted in the probe is then extended outward from the probe to longitudinally extend into the exposed column. A balloon seal mounted on the end of the instrumentation tube allows the bottom of the column to be sealed. A source of laser radiation is emitted from the instrumentation tube to ablate a sample from the exposed column. The instrumentation tube can be rotated in the probe to sweep the laser source across the surface of the exposed column. An aerosol transport system carries the ablated sample from the probe to the surface for testing in an inductively coupled plasma system. By testing at various levels in the down-hole as the probe is extracted from the soil, a profile of the subsurface formation may be obtained. | ||||||
