Класс МПК F04B 17/04 № заявки PCT/US2001/009006 Заявитель BAKER HUGHES INCORPORATED Изобретатель KOHL, Kristopher, T.

A chemical injection pump for injecting chemicals into subsea system at depths up to 10,000 feet is described which uses a minimum of moving parts by employing an actuator, for instance a solenoid, to power a double acting actuator rod and plungers thereon. The pump would generate low pressures and low fluid volumes, but be more durable and reliable than conventional rotating pumps operating under subsea conditions.

6.WO/1995/026454CURVED DRILLING APPARATUS

WO - 05.10.1995

Класс МПК E21B 7/04 № заявки PCT/US1995/002946 Заявитель AMOCO CORPORATION Изобретатель WARREN, Tommy, M.

A rotary drill bit (22) for drilling a curved subterranean borehole (26). In one embodiment, the drill bit comprises a side portion (40), a plurality of cutting elements (44) that produce a lateral force on the drill bit (22) in response to the rotation of the drill bit in the borehole, and bearing means (48). The bearing means is located on the side portion (40) of the drill bit (22) and contacts the borehole wall (28) during drilling to receive a reactive force that is from the borehole, that is in response to the lateral force and that is directed to a location adjacent to the uphole end of the side portion of the drill bit (22). The reactive force and the lateral force form a downhole-moment that is about the drill bit and that is opposed by an uphole-moment having a force component that is directed at the flexible joint (186). The uphole end of the bearing means (48) is located relatively close to the cutting elements (44) such that the magnitude of the downhole-moment and the magnitude of the uphole-moment are minimized.

7.WO/1996/028381PROCESS FOR PRODUCING IRON CARBIDE AND EQUIPMENT THEREFOR

WO - 19.09.1996

Класс МПК C01B 31/30 № заявки PCT/JP1996/000608 Заявитель KAWASAKI JUKOGYO KABUSHIKI KAISHA Изобретатель INOUE, Eiji

A powdery ore is preheated with hot air in a preheating furnace (2) and sent into a fluidized-bed reaction furnace (1). Iron oxide particles contained in the gas discharged from the furnace (2) are recovered in a dust collector (3) and are reduced in a reduction furnace (4). The reduced iron particles are fed into the passage leading to the reaction furnace (1), where they act as a catalyst for accelerating iron carbide formation.

8.WO/2000/029507EXTRACTION OF BITUMEN FROM BITUMEN FROTH AND BIOTREATMENT OF BITUMEN FROTH TAILINGS GENERATED FROM TAR SANDS

WO - 25.05.2000

Класс МПК C10G 1/04 № заявки PCT/US1999/019816 Заявитель BHP MINERALS INTERNATIONAL INC. Изобретатель DUYVESTEYN, Willem, P.C.

A process for the extraction of bitumen from bitumen froth generated from tar sands is disclosed. In this process, bitumen froth (9) is extracted from tar sands using a water process without requiring the use of caustic soda. The froth is treated in a counter-current decantation circuit with a paraffinic solvent to remove precipitated asphaltenes, water, and solids from the bitumen froth. A dilute bitumen product is produced having a final water and solids contents of about 0.01 to about 1 % by weight (32). This renders the dilute bitumen product amenable to direct hydrocracking. The process advantageously avoids the production of tailings sludges caused by clay dispersions. The present invention also includes a novel process for the biotreatment of bitumen froth tailings (47-52) resulting in a reduced amount of waste products and byproducts.

A method for producing a heavy crude oil from a subterranean formation through a wellbore and converting the heavy crude oil into a product distillate hydrocarbon stream and at least one of heat, steam, electricity and synthesis gas by separating distillable components of the heavy crude oil by distillation and solvent deasphalting and converting the asphaltic residual portion of the heavy crude oil in a fluidized bed to at least one of heat, steam, electricity or synthesis gas. In one embodiment, the heavy crude is diluted and the crude oil/diluent mixture is transported to a market location where the crude oil is subsequently converted. The method also produces diluent hydrocarbons useful as a separate product, a distillable hydrocarbon stream or in the production and transportation of the heavy crude oil.

10.WO/1999/033936EXTRACTION OF BITUMEN FROM BITUMEN FROTH GENERATED FROM TAR SANDS

A process for the extraction of bitumen from bitumen froth generated from tar sands is presented. The deaerated bitumen froth (12) produced by deaerator (11) is fed to primary mixer (13) where it is mixed with secondary settler overflow produced from the secondary settler (22), containing a large proportion of diluted bitumen and solvent, fed through suitable conduit (15). During mixing in primary mixer (13), the secondary settler overflow (15), containing diluted bitumen and solvent, solvates a portion of the bitumen contained in the bitumen froth and precipitates a portion of the contained asphaltenes.
