  • Patent number: 7093662
    Abstract: A system for controlling drilling mud density at a location either at the seabed (or just above the seabed) or alternatively below the seabed of wells in offshore and land-based drilling applications is disclosed. The present invention combines a base fluid of lesser/greater density than the drilling fluid required at the drill bit to drill the well to produce a combination return mud in the riser. By combining the appropriate quantities of drilling mud with a light fluid, a riser mud density at or near the density of seawater may be achieved to facilitate transporting the return mud to the surface. Alternatively, by injecting the appropriate quantities of heavy fluid into a light return mud, the column of return mud may be sufficiently weighted to protect the wellhead. At the surface, the combination return mud is passed through a treatment system to cleanse the mud of drill cuttings and to separate the drilling fluid from the base fluid.

  • Patent number: 7059426
    Abstract: An underground drilling method and apparatus generates intense pressure pulses at a location at the surface. The pressure pulses propagate down through a drill string to a drill bit. The pulses may be generated by creating water hammer in flowing drilling mud. Intensity of the acoustic pulses is increased in the bit nozzles. Vigorous pulsing of the fluid exiting the bit nozzles results in better cleaning of the hole bottom and faster drilling. The pulses may be used to drive the operation of various down hole tools. One type of tool has multiple pistons arranged in series. High pressure pulses move the pistons to generate strong mechanical vibration in the drill string. Vibration of the drill string may also reduce the friction between the drill string and the hole, resulting in lower torque requirements.

  • Patent number: 6347675
    Abstract: A method for increasing the efficiency of drilling operations by using a drilling fluid material that exists as supercritical fluid or a dense gas at temperature and pressure conditions existing at a drill site. The material can be used to reduce mechanical drilling forces, to remove cuttings, or to jet erode a substrate. In one embodiment, carbon dioxide (CO2) is used as the material for drilling within wells in the earth, where the normal temperature and pressure conditions cause CO2 to exist as a supercritical fluid. Supercritical carbon dioxide (SC—CO2) is preferably used with coiled tube (CT) drilling equipment. The very low viscosity SC—CO2 provides efficient cooling of the drill head, and efficient cuttings removal. Further, the diffusivity of SC—CO2 within the pores of petroleum formations is significantly higher than that of water, making jet erosion using SC—CO2 much more effective than water jet erosion.

Air is also injected into the bottom of the drilling mud and other waste fluids which are placed into the discard pit to evaporate the water and thereby accelerate consolidation or ultimate drying of the drilling mud for final disposal. This can be done as required during the drilling operation so that the consolidated or dried drilling mud can then be more easily and economically handled for transport to a hazardous waste disposal site, or can be more easily covered with earth while remaining in the discard pit.

  • Patent number: 3958650
    Abstract: A drill system for drilling very large holes in the earth, of diameters up to from 10 to 20 feet, by means of a rotary bit carrying a plurality of cutters, wherein the bit assembly is pressed against the bottom of the hole, so that the unit pressure against each of the cutters will be adequate for their optimum performance. The force holding the bit in contact with the bottom of the hole is created by the weight of the drilling liquid on top of the bit. A fluid seal is maintained between the outer edge of the bit and the wall of the bore hole. Liquid flows down the annulus around the drill pipe and through a plurality of orifices in the bit, terminating at the bit cutters. Rock cuttings are washed radially inwardly to a central drill pipe, which supports the bit, and through which torque is applied to the bit. The pressure drop in the orifices serves to create a differential pressure above and below the bit. The differential pressure times the exposed surface area of the bit provides the hold down force.
