| A novel method for disposing of drill cuttings and more particularly to the process for source identification of such cuttings and the identification of value added processes for commercializing the cuttings in an economical manner. The method of recycling of oil and gas well drill cuttings as disclosed herein begins by identifying drill cuttings by location, type of earth formation and earth strata level from whence extracted, drying, coding and containerizing said cuttings by said grade, mineral type, extraction location, and geological age. Uses for the recycled and graded drill cuttings include graded virgin aggregate for road construction including asphaltic cement, recyclable stone retaining walls and lawn ornaments or other applications useful in landscaping or water drainage control by mixing the dried and refined cuttings with recycled polymer. | ||||||
| 163 | Methods and apparatus for disposing of deleterious materials from a well | US10196914 | 2002-07-17 | US20040011562A1 | 2004-01-22 | Barry Simpson; Fabio Manotas; Tim Barr |
| An improved method and apparatus for processing deleterious material on a floating vessel during transportation from a well to a disposal site. The vessel contains equipment for the slurrification and agitation of the deleterious material. Such equipment includes storage tanks, slurrification units, and agitation units, as well as transfer equipment such as flow lines and vacuum or pump means. The deleterious material is transferred from the drill site to the storage tanks on the vessel. The vessel then transports the material to a disposal site, such as an injection well. During transportation, the deleterious material is processed. Such processing can include slurrification and/or agitation of the deleterious material to maintain the slurry, adding fluid if necessary. Once at the disposal site, the deleterious material slurry is then transferred from the vessel to the disposal site. | ||||||
| 164 | Method for disposal of liquid from gas wells | US10303965 | 2002-11-26 | US20030106694A1 | 2003-06-12 | Thomas R. Wiseman |
| Liquids recovered from a gas well processed in a ground flare for avoiding the expense of offsite disposal. Well gases are burned in first burners to form a primary combustion zone. Liquids for disposal are introduced and atomized through second burners or nozzles into the primary combustion zone. Preferably, a wellhead separator further separates liquids from gas recovered from the well. Liquids are stored in a tank and delivered to the second burners as the heat capacity in the flare permits. Supplementary commercial pilot gas can provide sufficient heat capacity if the well gas is temporarily insufficient. The liquid is incinerated and its combustion or vaporized products are discharged with the burned gas. | ||||||

| 169 | Method of cleaning boats that have been contaminated with oil and gas well drilling fluids and hazardous waste | US842244 | 1997-04-23 | US5908040A | 1999-06-01 | Arthur A. Defraites, Jr. |
| A system for cleaning vessels that have been contaminated with oil field drilling and production waste materials such as oil well drilling fluid or hazardous waste using recycled wash water. As dirty wash water accumulates in a vessel during cleaning, it is transferred to a settlement section of the waste receiving barge. A cationic polymer is injected into the suction side of a waste water pump during transfer of dirty fluid from the vessel to the receiving barge. The polymers react with fluids to begin an initial settling process within the waste receiving barge. Decant water is subjected to secondary settlement and secondary chemical treatment after it leaves the primary settling section of the waste receiving barge. The laundered water is returned to the wash water storage facility for reusing and cleaning the same vessel or additional vessels. In this fashion, waste is continuously concentrated in the receiving vessel for ultimate disposal at a remote site and wash water is recycled for reuse. | ||||||
| 170 | Precast prerotation basin system | US846125 | 1997-04-25 | US5871304A | 1999-02-16 | Joel Quinn; Eric Maass; David P. Borrowman |
| A precast prerotation basin system for use in a wet well for removing water or fluid therefrom is disclosed which comprises a prefabricated, three-dimensional body having a prerotation basin and fluid entrance channel.

| 177 | Method and apparatus for disposing of water at gas wells | US923699 | 1992-07-31 | US5335728A | 1994-08-09 | Ronald L. Strahan |
| A method and apparatus for disposing of water at gas wells. Water from the water holding tank is collected periodically in a heating vessel. Hot fluid from an auxiliary engine system, such as the oil pump or the water pump for the compressor engine, is pumped through a heat conductive coil around the heating vessel to heat the well water in the heating vessel. The heated well water then is injected into the hot exhaust line from the compressor either between the compressor and the muffler or alternatively is injected directly into the muffler. The heating vessel is pressurized with gas from the well to assist in the evacuation of the heated water from the heating vessel and the injection of the well water into the hot exhaust. A system of valves controls the delivery of water to the heating vessel, ensures that the heating vessel will not be over pressurized and deactivates the apparatus when the gas compressor is not running. | ||||||
| 178 | Process for recovery and treatment of a diverse waste stream | US618994 | 1990-11-28 | US5292429A | 1994-03-08 | Thomas F. DesOrmeaux |
| A process for removing and recovering specific constituents from a waste stream at higher temperatures than the boiling point of the specific waste within a compound of chemicals and inert materials forming ninety-five (95%) percent of the waste stream in the United States. In the process, the waste is moved at a specified retention time, through a heat zone, thus increasing the temperature of the waste stream. There is further provided a means to separate certain components in that waste stream, whereby the components are vaporized and are released in a gaseous state, either from a liquid or a solid within the waste stream. The gaseous components are then transferred in the gaseous state through a flow of an inert medium, such as nitrogen gas, to inhibit combustion of the components, or to prevent the combination of oxidation, or oxygen being used as a catalyst to form even more hazardous compounds. The gaseous components then are released in a distilled state, which would otherwise be mixed with the waste, or an emulsion with the waste stream, containing a heavy metal such as cadmium, arsenic, lead, or some other type of heavy metal which may be a threat to the environment. | ||||||
| 179 | Well drilling cuttings disposal | US964983 | 1992-10-22 | US5277519A | 1994-01-11 | James J. W. Nahm |
| Drilled cuttings are disposed of by solidification by drilling with a drilling fluid containing blast furnace slag, thereby producing drilled cuttings and other solid wastes, concentrating the wastes and then solidifying the concentrated wastes. Drilling wastes solidified by blast furnace slag are hard and unleachable and the blast furnace slag is compatible with both oil and water based drilling muds and drilled cuttings. Drilling fluids therefore do not have to be removed from the drilled cuttings prior to solidification in a mud pit. | ||||||
| 180 | Process and apparatus for recovering reuseable water form waste drilling fluid | US317156 | 1989-02-28 | US5093008A | 1992-03-03 | James Clifford, III. |
| A dewatering porocess and apparatus for recovering water from waste drilling fluid for concurrent reutilization in an active drilling operation includes a storage area, an intermixer for introducing treatment chemicals into the waste drilling fluid and a centrifuge. Flocculation is chemically induced in the waste drilling fluid as it passes through the intermixing means for introducing treatment chemicals into the waste drilling fluid. The waste drilling fluid is then transferred to the centrifuge wherein it is separated into solid waste and clear reuseable water. The water is returned to the storagge area and may be chemically adjusted prior to being returned to the drilling rig. | ||||||
