Класс МПК F25J 1/02 № заявки PCT/FR2002/002242 Заявитель TECHNIP FRANCE Изобретатель PARADOWSKI, Henri

A method for the liquifaction and denitrogenation of natural gas, a system for carrying out said method, and gases obtained by said separation. The invention relates to a method for the liquefaction and denitrogenation of natural gas (1) containing nitrogen, wherein said natural gas (1) is cooled, liquefied and separated into a first head fraction (9), which is relatively more volatile and enriched with nitrogen, and a first foot fraction (15). The method is characterized in that the first head fraction (9) is cooled and liquefied, separated into a second head fraction (11) which is relatively more volatile and which provides gaseous nitrogen (29), and a second foot fraction (12) which is re-treated, also characterized in that the first foot fraction (15) is cooled in order to provide liquefied natural gas which is essentially devoid of nitrogen (24). Other embodiments are also disclosed.

Класс МПК E21B 43/24 № заявки PCT/IB1998/000469 Заявитель TEXACO DEVELOPMENT CORPORATION Изобретатель HUANG, Wann-Sheng

Techniques are disclosed for the safe production of shallow heavy oil sands which substantially reduce the probability of surface steam breakthrough. A pattern of injection wells and producing wells is drilled through the overburden into a relatively shallow heavy oil producing zone. Firstly the injection wells and the producing wells are cold produced for a combination of heavy oil and sand by use of a progressive cavity pump or the like. The steam push-pull is used on both the injectors and producers until heavy oil production becomes uneconomical. Finally, low pressure steam is continuously injected into the injection well and heavy oil continuously produced from the producing wells.

WO - 22.11.2001

Класс МПК A01G 15/00 № заявки PCT/RU2000/000187 Заявитель PELEVIN, Vadim Nikolaevich Изобретатель PELEVIN, Vadim Nikolaevich

The invention can be used for protecting human life from dangerous and especially dangerous phenomena (hurricanes, typhoons) provoked by cyclones and also for regulating the volume of simultaneous precipitation events, being important for the agricultural sector (controlling tropical cyclones). The weakening of cyclones (hurricanes, typhoons) by preventing the destructive effect thereof is carried out by creating an atmospheric motion wherein certain areas thereof are influenced upon. In order to identify the troposphere impact areas, a value of available potential energy in the troposphere is calculated and the results are compared with a rating value of the available potential energy which produces a breakdown wind velocity dangerous for the environment. If a measured value of the available potential energy reaches the rating value of the available potential energy, one or several impact areas are selected for transformation of the available potential energy into kinetic energy, thereby forming a cyclone having a power which dos not exceed a destructive level.

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.

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.

6.WO/1998/046699METHOD FOR PRODUCING HEAVY CRUDE OIL VIA A WELLBORE FROM A SUBTERRANEAN FORMATION AND CONVERTING THE HEAVY CRUDE OIL INTO A DISTILLATE PRODUCT STREAM

WO - 22.10.1998

Класс МПК C10G 7/00 № заявки PCT/GB1998/001035 Заявитель ATLANTIC RICHFIELD COMPANY Изобретатель CRANE, Steven, D.

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 converting the residual portion of the heavy crude oil in a fluidized bed to at least one of heat, steam, electricity or synthesis gas. The method also produces diluent hydrocarbons useful in the production and transportation of the heavy crude oil. In one embodiment the heavy crude oil is mixed with a diluent to form a mixture which is then transported to a selected location for conversion of the heavy crude oil. The diluent is typically a hydrocarbonaceous distillate material which may be recovered as a separate product as part of the conversion step.
