Title: Identifying hydrocarbon yielding regions in a laminated sand/shale formation from horizontal and vertical resistivity measurements
Inventor: MINH CHANH CAO
IPC: G01V3/18
Filed: 2009-05-12
Abstract: A method for analyzing a formation includes plotting resistivity data points on a resistivity graph, presenting a cross plot of vertical and horizontal resistivity of the formation to a user. The user selects a first shale point on the resistivity graph based on the plotted resistivity data points. The first shale point represents a resistivity anisotropy of shale in the formation. The method further includes generating, for each of a plurality of shale fraction values, a first shale fraction curve on the resistivity graph based on the shale fraction value and the first shale point, and generating, for each of a plurality of sand resistivity values, a first sand resistivity curve on the resistivity graph based on the sand resistivity value and the first shale point. The curves are displayed to the user who identifies a hydrocarbon yielding region, or pay region, in the formation based on the first sand resistivity curves and the first shale fraction curves. The graph may also include a gamma ray axis and selection of the first shale point is also based on a gamma ray value. The depth of the pay region may be identified by viewing a depth log display.

IPC: C10G7/00
Filed: 1918-06-22
Abstract: 117,615. Barbet et fils et Cie, E. July 3, 1917, [Convention date]. Addition to 9088/14. Hydrocarbons, distilling.-In the continuous fractional distillation of petroleum, benzol, &c., the hydrocarbon is first dehydrated in an apparatus A, is then treated at atmospheric pressure in a plate column B for the separation of various grades of petrol, and is finally separated into white spirits, lighting petroleums, and a vaselinous residue by passage through apparatus D, E, F in succession. The apparatus D, E, F are under vacuum; the element E is heated by vapours generated in the element F, and the distillation in the element D is effected by the subjection of the hot liquid from the element B to the vacuum. The crude petroleum enters the dehydrating- column A by a pipe A' and the water with some of the petrol is evaporated by steam coils a<2>. The vapours are led to a condenser A<2>, and the petrol and water are separated in a testing-device a, the petrol being led to the boiler B' of the petrol-distilling column B. The dehydrated tar flows through a pipe b to the column B. Gasoline is obtained in a condenser B<2> receiving vapour from the column B and is led away by a pipe 1<1>. Petrol of various grades is collected from appropriate plates of the column B by means of pipes 2, 3, 4, 5. The hot petrol-free oil flows through a pipe b<2> to the column D and evaporates under the reduced pressure. Three grades of distillate are collected by pipes 6<5>, 7, 8. The residue flows by pipes d. c, e<2> to the elements E, F in succession. The elements E, F consist of boilers fitted with a froth-preventer and provided with heaters E<1>, F<1>. The heater F<1> is heated by steam, and the heater E' by vapours led from the element F by a pipe f. The fraction condensing in the heater E<1> is led away by a p pe 9<4>, and the uncondensed vapours are led by a pipe 9<5> to a cooler M. The vapours generated in the element E are led by, a pipe K to the column D to mix with those generated from the petroleum entering by the pipe d. The testing-devices of the apparatus D, E, F communicate with a vessel X which is evacuated by a pump Y which compresses the vapours inio a coil in a cooler L. Another coil in the coo'er L receives the vaselinous residue coming from the element F by a pipe f<1>.

Title: A new pentacyclic ketone and process for making it
IPC: C07D459/00
Filed: 1956-04-04
Abstract: The invention comprises 3-isoreserpone, quaternary compounds and acid salts thereof, particularly quaternary compounds with reactive alkanol esters, e.g. alkyl iodides, and salts with nitric, sulphuric, hydrohalic, alkane sulphonic, alkyl sulphuric, oxalic, tartaric and citric acids.  Isoreserpone is prepared by acid hydrolysis of an ester (particularly an alkyl ester containing from one to five carbon atoms in the alkyl group) of anhydroreserpic acid followed by decarboxylation of the resulting b -keto-acid.  The decarboxylation may occur spontaneously if the hydrolysis is effected with a strong inorganic acid.  In an example, methyl anhydroreserpate is refluxed in ethanol and 12 per cent hydrochloric acid, the mixture basified with sodium hydroxide and extracted with chloroform; the solvent is evaporated and the residue purified by chromatography on alumina, when elution with benzene and increasing proportions of acetone yields firstly reserpone and then 3-isoreserpone.  Other alkyl anhydroreserpates may be used.  The alkyl anhydroreserpates are in turn prepared by refluxing the corresponding O-p-toluene sulphonyl reserpate (obtained from the alkyl reserpate and p-toluene sulphonyl chloride) with collidine. Specification 744,290 is referred to.ALSO:Sun screen compositions comprise isoreserpone or its acid salts or quaternary derivatives incorporated into a hydrophilic ointment, which may contain glycols such as propylene glycol, higher aliphatic alcohols such as stearyl alcohol, white petrolatum or distilled water.  The creams preferably contain from 3 to 5 per cent of the active compounds.  Isoreserpone, when quaternized by reaction with esters of higher alcohols, e.g. dodecyl alcohol, also yields valuable disinfectants, particularly active against Staphylococcus aureus.

Title: Improvements in or relating to the welding of seams in metallic tubing
IPC: B23K13/02
Filed: 1948-04-15
Abstract: 643,816. Electric welding. GENERAL ELECTRIC CO., Ltd., BAKER, W. F., and SPENCER, J. R. April 15, 1948, No. 10517. [Class 83 (iv)] In welding a seam in tubing &c. a line contact or line contacts in series is or are formed between the opposing faces of the seam within the thickness of the parts, either by shaping one or both faces of the seam or by placing a conducting wire between the faces, and inducing in the parts a high-frequency welding current which flows across the seam through the line contact or contacts. The welding current is induced by passing the tubing through a high-frequency induction heating coil 2 and pressure rolls 5 may be used to force the faces of the seam together, or the differential expansion due to the concentration of the heating from the induced current on the outer skin of the tubing may be relied on for this purpose. The line contact between the seams may be produced by having a tapered projection 6 on one or both faces or by placing a wire 3 between the two faces, which may then be slightly concave in order to grip the wire. The wire may be heated to near its melting point, as it is fed between the faces, by current supplied through a guide roll 4 and the rolls 5. The projections 6 are so placed radially that, after welding, no ridge is left on the inside of the seam and, if there is a projection on each face, they may abut or may overlap slightly so that a mechanical pressure, acting in a radial direction, is caused between the faces, the tubing being slightly unsymmetrical until after it is welded.
