Abstract: Systems, apparatus, and methods for controlling a well blowout comprising: a flow control device such as a blowout preventer on a wellbore, the primary throughbore of the flow control device comprising internal dimensional irregularities creating a non-uniform flow path in the primary throughbore which as sufficient fluid rate may enhance pressure fluid pressure drop therein; a control fluid aperture fluidly connected with the wellbore for introducing a control fluid through a control fluid aperture and into the primary throughbore while wellbore fluid flows through the wellbore; a weighted fluid aperture positioned in the wellbore conduit below the control fluid aperture for introducing a weighted fluid into the wellbore while control fluid is also being introduced into the wellbore through the control fluid aperture.

Abstract: The present techniques are directed to a system and method for generating power and recovering methane from methane hydrates. The system includes a low emissions power plant configured to generate power, wherein an exhaust gas from the low emissions power plant provides a gas mixture including nitrogen and carbon dioxide. The system also includes a methane recovery system configured to recover methane from methane hydrates by injecting the nitrogen and the carbon dioxide from the gas mixture into the methane hydrates.

Abstract: Systems, apparatus, and methods for controlling a well blowout comprising: a flow control device such as a blowout preventer on a wellbore, the primary throughbore of the flow control device for introducing control fluid into the primary throughbore portion of the wellbore throughbore to create a pressure drop within the primary throughbore sufficient to overcome the flowing blowout fluid pressure within the primary throughbore and optionally introducing control fluid into the primary throughbore using a conduit inserted directly into the wellbore throughbore to further enhance introduction of control fluid into the wellbore throughbore; and optionally a weighted fluid aperture may be positioned in the wellbore conduit, preferably below the control fluid aperture for introducing a weighted fluid into the wellbore throughbore while control fluid is also being concurrently introduced into the wellbore through the control fluid aperture.

Abstract: A method for entraining hydrate particles in a gas stream, including separating a raw gas stream into a bulk water stream and a partially dehydrated gas stream, chilling the partially dehydrated gas stream to form a chilled gas stream, combining the bulk water stream with the chilled gas stream to form a transport stream including the entrained hydrate particles, and flowing the transport stream to a facility.

Abstract: Compounds of formula (1) ##STR1## are described wherein Y represents a halogen atom or a group --OR.sup.1, where R.sup.1 is an optionally substituted alkyl group; R.sup.2 represents an optionally substituted cycloalkyl or cycloalkenyl group; R.sup.3 is a monocyclic or bicyclic aryl group optionally containing one or more heteroatoms selected from oxygen or sulphur atoms or a group --N(R.sup.4)-- where R.sup.4 is a hydrogen atom or an alkyl group; X is --O--, --S--, or --N(R.sup.5)--, where R.sup.5 is a hydrogen or an alkyl group; with the proviso that when X is --O-- then R.sup.3 is not a 3-cyanamino-6-pyridazinyl or a 3-chloro-6-pyridazinyl group; and the salts, solvates, hydrates and N-oxides thereof.The compounds are selective and potent inhibitors of phosphodiesterase IV and are useful for the prophylaxis and treatment of inflammatory diseases and the alleviation of conditions associated with central nervous malfunction.

Abstract: Cross-linking reagents which are highly specific for sulphydryl groups and react with thiols at an excellent rate. The essential feature of the reagents is at least one vinyl group conjugated with an armoatic nitrogen heterocycle. Particular examples include vinyl pyridines, vinyl pyrimidines and vinyl triazines.

Abstract: A synthetic gene characterised in that it codes for the expression of urogastrone or a sub-unit thereof is disclosed.The production thereof by the assembly and ligation of a number of nucleotide blocks is also disclosed, as are corresponding plasmid recombinants, transformed cells and the production thereof.The expression of urogastrone is further disclosed.Urogastrone is a polypeptide hormore (protein) which may be isolated in small amounts from human urine. It has an application in the treatment of ulcers and in the promotion of wound healing. The present invention provides a more viable commercial production.
