DETAILED DESCRIPTION OF THE EMBODIMENTS
Before explaining the present system in detail, it is to be understood that the system is not limited to the particular embodiments and that it can be practiced or carried out in various ways.
The embodiments relate to a continuous microwave particulate treatment system for treating drilling waste from a wellbore using a materials handling controller.
The continuous microwave particulate treatment system for treating drill cuttings continuously operates a means for separating particulate from drilling fluid to separate a slurry from drilling fluid from a wellbore.
The system can include a cuttings discharge collection device for continuously moving the slurry to a cuttings processing station from the means for separating particulate from drilling fluid.
A treatment system controller can control the cuttings processing station that uses a microwave generator for creating microwaves that heat the slurry and heat a plurality of non-deforming microwave heatable polishing and grinding media in a vibrating trough.
The two controllers and the apparatus are used to continuously create (i) a water vapor with oil droplets and (ii) cleaned cuttings from the slurry.
In embodiments, the system can include a connected vapor recovery system for removing the oil droplets from the water vapor.
The vapor recovery system can have a vapor recovery system controller in communication with the material handling controller and treatment system controller to manage transport, preventing overflow, and ensuring continuous discharge of particulate.
The following definitions are used herein.
The term “buffer tank” can refer to a metal or other vessel which can hold slurries, such as 50 to 250 barrels of slurry.
The term “cuttings discharge collection device” can be a screw conveyor or an auger for continuously moving cuttings discharge from the means for separating particulate from drilling fluids on the drilling rig away from the means for separating particulate from drilling fluids.
The term “fluid” as used herein can include drill cuttings in particulate form, in a slurry or in a mud, and can include other particulates, such as barite, bentonite and other particulates.
The term “G force” refers to gravity force on the particulates in the vibrating trough.
The term “non-deforming microwave heatable polishing and grinding media” refers to a variety of microwave absorbing materials, such as ceramic balls with diameters from 1 inch to 6 inches. In embodiments, the non-deforming microwave heatable polishing and grinding media are selected for the rate of absorbing and rate of emitting the microwave energy as heat. In embodiments the non-deforming microwave heatable polishing and grinding media can have different shapes. In embodiments, the non-deforming microwave heatable polishing and grinding media can have different diameters, lengths and widths.
The term “particulate” as used herein can refer to waste, including drilling cuttings from drilling fluid or fluid produced from working over a wellbore.
The term “pneumatic conveyor” refers to a controllable pressurized vessel that is pressurized from a compressed air supply. In embodiments, the pneumatic conveyor can accept pressurized air in a low pressure range from 20 psi to 200 psi.
The term “power supply” can refer to a rig power supply, a utility supplied power connection, or freestanding generators connected to a fuel supply.
The term “screw conveyor” refers to a variety of rotating Archimedes screws or screw pumps for transporting material including slurries. In an embodiment, a screw conveyor can be an auger. The screw conveyors can vary in length and speed of rotation.
The term “means for separating particulate from drilling fluid” refers to vibrating sieve devices such as shakers or other filtering devices to remove a user defined size of solids from slurry, such as devices that use screens classified by the American Petroleum Institute (API) RP13C. An exemplary means for separating particulate from drilling fluid can remove particles with diameters from 0.1 inch and 0.3 inches.
A feature of the invention is that no additional liquid other than water needs be mixed with the drill cuttings or fluid from the work over. More specifically, no ionic liquids need be mixed with or otherwise placed in contact with particulate matter prior to removing at least one hydrocarbon from the particulate using this system. The current system is much more environmentally friendly than currently available systems. The current process minimizes the need for additional toxic material while separating the oil from the particulate.
The invention is usable for treating drilling fluid containing drill cuttings, crude oil containing sand, beach sand contaminated with oil, oil sludge, any hydrocarbon containing sand, soil, rock, silt, clay or other solid particulate or any hydrocarbon contained within sand, soil, rock, silt, clay or other solid particulate, such as Barite.
The system can involve simultaneously heating water from the drilling fluid or workover fluid, which does not contain added ionic liquids, to separate oil and water from particulate matter at relatively low temperatures as low as 100 degrees Celsius, while simultaneously vibrating the particulate to ensure thorough cleaning, that is, thorough removal of the oil from the particulate.
Optionally, the separation temperature can be raised to lower the viscosity of the hydrocarbon being separated and aid in separation of hydrocarbon from particulate material and create a vapor with oil particles suspended in the vapor.
In the invention, the separation temperature can be raised by microwave heating of the particulate and non-deforming microwave heatable polishing and grinding media surrounding the particulate, while simultaneously vibrating the particles, all done offshore, without the need to transport the drill cuttings to another location.
While using little energy, the invention produces cleaned material.
The invention creates a small carbon footprint enabling the device to be desirable on rigs needing compliance with Environmental Protection Agency requirements.
The invention uniquely requires no additional solvent such as toluene to be added or mixed to the drilling cuttings or drilling mud in order to clean the particulate. Only the water in the drilling fluid is targeted by the microwave generators for preferential heating of the water while also heating the isotropic radiator in the trough.
The invention has the simultaneous feature of heating while vibrating, capturing the oil in the vapor and then have a vapor recovery system which can all be handled directly on a rig.
There is no need to use any organic solvent to dissolve non-polar hydrocarbons such as bitumen, oil or drilling fluid. There is no need to add any type of organic solvent can include toluene, naphtha, hexane, kerosene, paraffinic solvents or any other non-polar hydrocarbon solvent that dissolves the hydrocarbon. There is simply no need to dissolve the hydrocarbon in another substance other than water creating an improved separation process.
The invention is a continuous microwave particulate treatment system for fluid from a wellbore.
The invention can use three different controllers simultaneously to control and operate the equipment recover oil from fluids from a wellbore, and produce cleaned particulate.
In embodiments, a single master controller can operate the entire system.
One controller can be a treatment systems controller to continuously operate a means for separating particulate from drilling fluid for separating slurry from the fluid as well as operate a cuttings discharge collection device for continuously moving the slurry to a cuttings processing station.
The treatment systems controller can also operate the cuttings processing station that simultaneously vibrates and heats particulate from the fluid from the wellbore.
The second controller can be a material handling controller that communicates to a cuttings discharge collection device, a surge storage, a first pneumatic conveyor and a screw conveyor all simultaneously for transporting the treated material to discharge.
The cuttings processing station can have a vibrating trough, a plurality of non-deforming microwave heatable polishing and grinding media disposed in the vibrating trough, at least one microwave generator for creating microwaves that heat the slurry and the non-deforming microwave heatable polishing and grinding media in the vibrating trough, and a microwave waveguide for each microwave generator targeting microwaves into the vibrating trough to continuously create (i) a water vapor with oil droplets and (ii) cleaned cuttings.
The invention can include a vapor recovery system which can have a vapor recovery system controller.
The three controllers can communicate with each other allowing for continuous drilling fluid or work over fluid treatment, continuous vapor treatment and continuous disposition of the cleaned particulate.
Turning now to the Figures, FIG. 1 depicts a diagram of a portion of the particulate treatment system and materials handling equipment to separate oil from particulate such as drill cuttings from drilling fluid, or oil from work over fluid.
The depicted portion of the particulate treatment system can continuously treat the drill cuttings and fluid containing particulate as the drilling fluid comes from the well.
The particulate treatment system can treat particulate from 2 microns to 1000 microns in diameter.
The particulate treatment system can include a plurality of means for separating particulate from drilling fluid 10a, 10b, and 10c, which can be shakers, as shown in this embodiment.
Each means for separating particulate from drilling fluid can continuously receive fluid from a wellbore and continuously separate slurry 16a-16c from the fluid 25 from the wellbore.
In embodiments, the slurry can be made up of cuttings discharge and an oil and water emulsion.
A usable means for separating particulate from drilling fluid can be a SCOMI PRIMA GTM 3 panel, 4 panel or 5 panel configuration shaker. Typically, a 6 G force to 9 G force shaker can be usable herein.
The means for separating particulate from drilling fluid 10a can produce slurry 16a, the means for separating particulate from drilling fluid 10b can produce slurry 16b, and the means for separating particulate from drilling fluid 10c can produce slurry 16c. 
Each means for separating particulate from drilling fluid can be connected to a power supply 11a, which can be an on rig diesel generator or a ship's electrical system.
Additional treatment equipment described herein can be powered by a second power supply 11b. 
In embodiments, additional solids control equipment can be used after the means for separating particulate from drilling fluid.
The additional solids control equipment installed after the means for separating particulate from drilling fluid can be desilters, desanders, mud cleaners, decanting centrifuges, cuttings driers, and combinations thereof. Typical cuttings driers can be perforated bowl centrifuges.
Slurries 16a, 16b, and 16c can flow into a cuttings discharge collection device 50.
In embodiments, the cuttings discharge collection device 50 can be a screw conveyor for continuously flowing the slurry away from the means for separating particulate from drilling fluid.
The cuttings discharge collection device 50 can be connected to the first power supply 11a if the cuttings discharge device is a moving device.
In embodiments, the cuttings discharge collection device 50 can be an auger which rotates.
In other embodiments, the cuttings discharge collection device can be a non-moving device that uses gravity to flow slurry from the means for separating particulate from drilling fluid.
Using a gravity device as the cuttings discharge collection device can require a configuration wherein the means for separating particulate from drilling fluid is at an elevation greater than the cuttings discharge collection device, allowing gravity to move the slurry away from the means for separating particulate from drilling fluid, as the slurry enters the gravity device, which can be a gravity ditch in embodiments.
In embodiments, the lack of moving parts is a feature of this invention. It improves the overall safety of the system.
A cuttings discharge collection device without moving parts also has no need for energy, reducing the carbon footprint of the overall invention.
The cuttings discharge collection device 50 can transfer the slurry 16d to surge storage 52. The surge storage can be a tank.
The rate at which slurry 16d enters the surge storage 52 can be controlled by a materials handling controller 45 in electronic communication with valves on the surge storage.
The surge storage, in embodiments, can have a 2 ton to 30 ton capacity. The surge storage can have any size that can fit in the space available on the offshore rig, such as on the rig deck. The surge storage can be vented in embodiments.
The materials handling controller 45 can communicate bidirectionally with the cuttings discharge collection device 50 and with the surge storage to monitor and control continuous movement of the slurry and continuous treatment of the slurry by the means for separating particulate from drilling fluid without creating overflows of material into the sea or spilling in another manner.
The material handling controller 45 can communicate simultaneously with a cuttings discharge collection device 50, a surge storage 52, a first pneumatic conveyor 56 and a first screw conveyor 58 in embodiments.
The material handling controller 45 can be powered by the power supply 11a. 
The material handling controller 45 can also communicate with two buffer tanks 20a and 20b. Each buffer tank can have an inlet valve 21a and 21b, which can communicate electronically with the material handling controller 45, and an outlet valve 23a and 23b, which can communicate electronically with the treatment system controller 44.
The first screw conveyor 58 can be connected to the surge storage 52 for moving the slurry from the surge storage to a first pneumatic conveyor 56 according to preset volume limits for the surge storage stored in the material handling controller 45.
The material handling controller 45 can use computer instructions to activate the pneumatic conveyor 56 when the preset volume limits are approached as detected by a sensor 204 in the surge storage that communicates directly with the material handling controller.
The material handling controller can use computer instructions to activate the first screw conveyor 58 to additionally move slurry when the drilling rig is producing drilling cuttings and drill fluid at a rate higher than the pneumatic conveyor can operate.
The first screw conveyor 58, in embodiments, can be an Archimedes screw auger. In other embodiments, the screw conveyor can be a device that does not require a screw, such as a gravity fed conveying device, such as a gravity chute.
The first pneumatic conveyor 56 can be fluidly connected to the first screw conveyor for moving slurry from the surge storage at variable rates, such as from 1 ton an hour to 60 tons an hour, for example. The first pneumatic conveyor 56 can also be connected to the power supply 11a. 
The material handling controller 45 can use computer instructions to change the rates of movement of the slurry from the surge storage using the first pneumatic conveyor for continuous fluid flow, without overflowing or allowing back up.
A usable pneumatic conveyor is the SCOMI CBPTM 800 pneumatic conveyor having no more than 120 psi, and which can be as low as 40 psi, for safe, low pressure operation on a drilling rig.
The treatment system controller 44 can be connected to the power supply 11b. 
In addition to communicating with the material handling controller 45, the treatment system controller 44 can communicate bidirectionally with the buffer tanks 20a and 20b; a second screw conveyor 60; the continuous cuttings processing station 30; a second pneumatic conveyor 62 for conveying discharge to a transport vessel 64, such as a workboat; and a filling station 61.
Multiple screw conveyors can be used in the system sequentially or in parallel to increase capacity for treating the continuously flowing drilling fluid.
The buffer tanks 20a and 20b can be in fluid communication with the first pneumatic conveyor 56 for receiving slurry and providing buffer storage for the continuous drilling fluid treatment.
In embodiments, each buffer tank can hold from 20 tons to 30 tons.
In an embodiment, one buffer tank can have a volume of less than 20 tons by connecting to the first tank in series to prevent overflow of the material handling system of the invention.
The buffer tanks are shown connected in parallel, but other embodiments can have the buffer tanks connected in series. The buffer tanks can be steel tanks.
In embodiments, the buffer tanks can be sufficiently rigid, such that the entire buffer tank can be lifted by a crane without deforming while empty of slurry.
In embodiments, the valves and on each tank can be in communication with the treatment system controller 44 to regulate the continuous treatment of the fluid from the wellbore without overfilling the buffer tank or overfilling the second screw conveyor 60.
The valves can be an actuatable knife gate valves, butterfly valves or ball valves.
In an embodiment, the valves of the buffer tanks can be operated by the both the treatment system controller 44 and the material handling controller 45 using computer instructions in both controllers that compare the flow rates from the tanks to the flow rates of other equipment controlled by the respective controller, and then open or close valves to increase or decrease flow rates based on preset limits.
The second screw conveyor 60 can be electronically connected to the treatment system controller 44.
In embodiments, the second screw conveyor can be a 16 inch diameter auger that can rotate at a variable speed and is capable of moving slurry at rates from 1 ton an hour to 60 tons an hour.
The second screw conveyor 60 can be connected to the power supply 11b. 
The second screw conveyor 60 can move fluid from the buffer tanks to a continuous cuttings processing station 30.
The continuous cuttings processing station 30 can be electronically connected to the treatment system controller 44 and can be in fluid communication with the second screw conveyor 60.
After treatment by the continuous cuttings processing station 30, the slurry can be processed into two different flows, a flow of water vapor with oil droplets and cleaned cuttings 38a and 38b. 
The cleaned cuttings can be moved in two different directions as shown.
Cleaned cuttings 38a can be transferred to a second pneumatic conveyor 62 which can be controlled by the treatment system controller 44 for conveying the cleaned cuttings to a transport vessel 64, such as a truck, barge or rail car.
For example, a 1 ton to 30 ton an hour pneumatic discharge conveyor 62 can be used in the system.
In embodiments, the cleaned cuttings 38b can be transferred to a filling station 61.
The filling station 61 can be used for filling skips, such as 8 ton skips, with the cleaned cuttings in this continuous treatment process. The filling station can be located on the drilling rig.
In embodiments, the filling station 61 can be an auger with multiple discharge points for filling skips. The filling station can be an auger capable of moving cleaned cuttings at rates from 1 ton to 60 tons an hour.

FIG. 2 depicts an embodiment of the continuous cuttings processing station.
The continuous cuttings processing station 30 can have a vibrating trough 70 that can vibrate at from 2 G forces to 6 G forces. The G force can be created, in embodiments, by an eccentrically weighted shaft of the vibrating trough that is operated by a motor.
The vibrating trough 70 can be connected electronically to the treatment system controller and electrically to the power supply.
In embodiments, the vibrating trough 70 can have a shape that is elliptical, oval or linear, such as straight.
In the vibrating trough 70, a plurality of non-deforming microwave heatable polishing and grinding media 71a-71c can be disposed.
In embodiments, the non-deforming microwave heatable polishing and grinding media can have a shape that is circular, triangular, rectangular, oval, or another angular shape.
In embodiments, the vibrating trough can be filed with a quantity of non-deforming microwave heatable polishing and grinding media that fill from 10 percent to 50 percent by volume of the vibrating trough. In different embodiments, up to 20,000 non-deforming microwave heatable polishing and grinding media can be used in a 6 to 20 foot long vibrating trough depending on the diameter of the non-deforming microwave heatable polishing and grinding media.
In embodiments, it is important that the non-deforming microwave heatable polishing and grinding media are not large, having diameters from 0.25 inches to 0.5 inches each.
The continuous cuttings processing station 30 can have at least one microwave generator for heating the vibrating particulate in the vibrating trough. Two microwave generators 33a and 33b are shown. Each microwave generator can be electrically connected to the power supply and electronically connected to the treatment system controller.
The microwave generators 33a and 33b can produce microwaves 72a and 72b respectively. The microwaves can heat the oil and water emulsion in the slurry and the non-deforming microwave heatable polishing and grinding media simultaneously.
In embodiments, the microwave generators can generate from 75 kilowatts to 150 kilowatts of microwave energy.
A special feature of this invention relates to the use of the microwave generators.
In this invention, the microwave generators are used to preferentially heat water first, rather than heat the entire slurry. By preferentially heating the water first the microwaves create a steam that strips the oil from the cuttings and carries off the oil for recovery with the water vapor.
A major advantage of this invention is that the microwave generators use less energy for cleaning cuttings than any known device, by at least 15 percent.
In embodiments, the invention is anticipated to clean cuttings using 30 percent less energy, and upwards of 50 percent less energy than commercial devices that heat all of the slurry rather than preferentially heat the water in the slurry first along with heating the non-deforming microwave heatable polishing and grinding media.
In embodiments, each microwave generator can use a microwave waveguide 73a and 73b. 
Each microwave waveguide can direct microwaves produced from each microwave generator to the vibrating trough for preferentially heating the water in the slurry and for heating the non-deforming microwave heatable polishing and grinding media in the vibrating trough.
The flow of slurry, which can include drill cuttings, can flow into the continuous cuttings processing station 30 from the second screw conveyor 60.

The vapor recovery system 500 can have a fin fan heat exchanger 508 for cooling the heated vapor stream 506 to a lower temperature forming a heated vapor and cooled liquid stream 531.
The heated vapor and cooled liquid stream 531 can be transferred from the fin fan heat exchanger 508 to a separation tank 533.
The separation tank 533 can allow first cooled liquid stream 537 to drop out for removal to an oil and water separator 514. The separation tank 533 can also create a stream of remaining heated vapor 535 which can then be transferred to a cooling unit 520.
The cooling unit 520 can receive the remaining heated vapor 535 from the separation tank 533 and form a condensed vapor 521.
A condensation tank 522 can receive the condensed vapor 521 and form a second cooled liquid stream 523. The second cooled liquid stream 523 can be mixed with the first cooled liquid stream 537 and then transferred to the oil and water separator 514.
The oil and water separator 514 can receive the oil stream 504 from the scrubber 502 and the cooled liquid stream from the separation tank and the condensation tank.
The oil and water separator 514 can produce recovered oil 512 from these inflows and transfer the recovered oil 512 to a tank.
Water formed in the vapor recovery process can be further treated and then returned to the sea, transferred back into the drilling fluid, or removed from the drilling rig.
The condensation tank 522 can be used for separating residual vapor 524 from condensed vapor 521 forming a second cooled liquid stream 523. Also, the condensation tank can be in communication with the vapor recovery system controller 501.
