Patent EP-0023399-A2 (EP)
Inventor: FREDD JOHN VICTOR
IPC: E21B47/06
Filed: 1980-07-10
Abstract: The present invention relates to a method and apparatus for testing petroleum wells. It is highly desirable when testing a well's potential to be able to allow the well to flow at normal flow rates and to be able to shut down the well and determine the pressure build-up move after a well has been producing the normal flow rates. It is known to introduce either a drill stem test system or a tubing test system after the well has been drilled, to obtain pressure-build up curves and allow the well to flow a full flow rates. In both instances packers (14) are introduced into the well on a string, testing is completed, and then the entire tool string is withdrawn from the well leaving the well dependent upon the drilling mud therein, blow-out preventers, etc., to maintain control of the well until it is completed. It is, however, desirable in conjunction with the testing procedure to provide for shutting down of the well adjacent the production formation and to use the same well control equipment for both testing and shutting down. 
<??>The present invention meets this desire by providing a well test apparatus comprising a well packer (14) having a bore extending therethrough with a sleeve-type foot valve (15) having a bore therethrough, depending from said packer (14). A tubular actuator (13) also having above extending therethrough, engages on top of the packer (14) and has an actuator member (44a) which extends through the packer (14) and, can open and close the foot valve 915). The actuator (13) also includes a pressure responsive member (44) which is exposed to pressure within and outside said actuator (13) for moving the actuator member (44a) vertically in response to a differential in pressure between the inside and outside of the valve (15), to thus open and close the foot valve (15). The well can thus be tested at full flow rates and the actuator (13) retracted from the well leaving the packer (14) and foot valve (15) sealing the well until such time as the well is to be completed and production commenced.

Abstract: Molecular coordination complexes are formed between a cellulose polymer and a non-polar solid aliphatic alcohol containing 8 to 18 carbon atoms optionally substituted with an aliphatic group containing 8 to 18 carbon atoms by solvating the polymer with a volatile polar solvent and reacting the solvated cellulose polymer directly with the aliphatic alcohol, preferably as a melt. The resulting composition may be dried. This constitutes the complex. The composition has utility as a matrix in controlled release formulations since it has a uniform porosity which may be varied.

Abstract: In protective casings for medical thermometers, consisting of plastic strips welded at their edges, there is the problem of irritation to the body of the patient in the course of use in consequence of the outwardly projecting, relatively hard weld seams. When such an inner protective casing is accommodated in an outer protective casing, the usual ointment coating on the outer surface of the inner protective casing is moreover stripped off in the course of removal, especially again at the weld edges of the inner casing. The protective device exhibits an inner protective casing with inwardly projecting weld edges (b), which is obtained by reversal of a casing which is produced in conventional manner initially with outwardly disposed weld seams. At the outer surface of the inwardly projecting weld seams grooves (d) are formed with an intensified ointment filling (e). <IMAGE>

Abstract: Herein disclosed is such a printing device to be used with a hand labeler or the like as is enabled to prevent in advance a printing medium such as labels or tags from being thinly printed so that averaged clean prints may be made at all times. The printing device includes actuating means for bringing a printing head into and out of engagement with a printing medium such as a label so that the printing medium may be imprinted. Further inclusive is a counting mechanism which is made cooperative with the actuating means for counting the number of prints. When this counting mechanism counts a predetermined number of prints, a print stopping mechanism stops the operation of the actuating means. A print returning mechanism releases the stopped condition of the actuating means so that the printable condition may be restored.

Abstract: A process for catalyzing the sulfurization of olefins and the resulting products are disclosed in which the catalyst is a tertiary phosphine such as a trihydrocarbyl phosphine or a trihydrocarbyl phosphine sulfide. The catalyst is preferably soluble in the olefin and, in the presence of elemental sulfur, the reaction mixture is heated to a temperature sufficient to sulfurize the olefin. The catalyst enables the sulfurization to proceed at lower temperatures than would be employed without catalysis. Atmospheric pressure production is possible of high sulfur-containing olefins which normally boil or reflux strongly at or below sulfurization temperatures. In addition, the product of the catalyzed reaction has certain advantages, such as improved oil solubility with no subsequent dropout.

Abstract: A flow detector, for use adjacent a steam trap to detect an unacceptable level of leakage of steam through the trap, comprises a tubular housing 10 substitutable for a standard pipe nipple. The housing comprises a boss 16 which provides a condensate collecting trap 24 in which an electrode 26 is exposed. Immediately opposite the trap 24, on the opposite side of a flow passage 28 provided by the housing 10, is a baffle in the form of a ramp 30 arranged to divert steam towards the trap 24. In normal conditions of use, the presence of condensate in the trap is signalled by an electric current passing between the electrode 26 and the housing 10. Should an excessive steam flow occur in the passage 28, steam diverted by the ramp 30 displaces the condensate from the trap 24 around the electrode 26 and stops the flow of current.A similar detector could be of use in a compressed air line.

Abstract: The invention deals with a two-feed pressure swing adsorption process for enhancing the recovery of hydrogen in a feed gas. 
     One portion comprising about 30-80% of a hydrogen-containing feed gas having a relatively high carbon dioxide content is preheated to remove a substantial portion of said carbon dioxide therefrom. The thus-preheated stream is passed to a pressure swing adsorption bed from which a purified hydrogen stream is withdrawn. Upon completion of this step, the unpretreated portion of the feed gas is passed to the feed end of the bed, with purified hydrogen continuing to be withdrawn from the bed. In cyclic pressure swing adsorption operations employing such a two-feed process, the recovery of purified hydrogen is enhanced as compared with operations in which none of the feed gas is pretreated for carbon dioxide removal or in which all of the feed gas is so treated for removal of carbon dioxide therefrom.

Abstract: In a ring network (1) messages sent from any one of a group of stations (3) to all the remainder include an acknowledgement field (ACK) holding a count preset to equal the number of expected destination stations. Each destination station that successfully receives the message acknowledges by decreasing the count by 1; acknowledgement is withheld if an error is detected in the message or the station cannot accept it. Acknowledgement is performed by a circuit (17) in a loop-through path (15) in an interface unit (4) connecting the station to the network (1). The originating station checks in a circuit (28) if the final value of the count on its return is zero. If so, the originating station is assured that each expected destination has made a positive acknowledgement of successful receipt.

Abstract: A method of nuclear magnetic resonance imaging of a body in which the spins of a chosen nucleus in a selected slice (43) of the body are rotated through an angle appreciably greater than 90° by applying, in sequence, two substantially identical r.f. pulses (B 1 (90°), B 2 (90°)) accompanied by a magnetic field having a gradient (G  1 z, G 2 z) in a direction orthogonal to the plane of the slice (43). Each r.f. pulse is at the Larmor frequency for the chosen nuclei in the slice (43), and is effective to rotate the spins by not greater than 90° and the r.f. pulses together are sufficient to rotate the spins through the angle. The gradients of the magnetic fields are in opposite directions.
