摘要： A method for inhibiting the formation of clathrate hydrates in a fluid having hydrate-forming constituents involves treating the fluid with an inhibitor comprising a substantially water soluble polymer having a polymer backbone .with a pendant C.sub.1 --C.sub.3 alkyl group; the polymer having an average molecular weight between about 1,000 and about 6,000,000. Preferably, the pendant alkyl group is a methyl group. The rate of nucleation, growth, and/or agglomeration of gas hydrate crystals in a petroleum fluid stream Is reduced using the alkylated polymer backbone inhibitor, thereby inhibiting the formation of a hydrate blockage in the pipe conveying the petroleum fluid stream. Test results are disclosed which unexpectedly show that alkylating the polymer backbone with a methyl group will produce a subcooling for the alkylated polymer that is at least about 2.degree. F. (about 1.1.degree. C.) greater than its nonalkylated counterpart. The inhibitor can be used conveniently at low concentrations, for example in the range of from about 0.01% to about 5% by weight of the water present in the oil or gas stream, to effectively treat a petroleum fluid having a water phase.

摘要： A method for inhibiting the formation of clathrate hydrates in a fluid having hydrate forming constituents is disclosed. More specifically, the method can be used in treating a petroleum fluid stream such as natural gas conveyed in a pipe to inhibit the formation of a hydrate restriction in the pipe. The hydrate inhibitors used for practicing the method are substantially water soluble polymers formed from a N-substituted acrylamide having two nitrogen substituent groups, R.sub.1 and R.sub.2, where R.sub.1 is a hydrocarbon group having from one to ten carbon atoms and zero to four heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur, and combinations thereof, and R.sub.2 is a hydrogen atom or a hydrocarbon group having from one to ten carbon atoms selected from the group consisting of carbon, nitrogen, oxygen, and sulfur; alternatively, R.sub.1 and R.sub.2 may be linked to produce a cyclic ring having ten atoms comprising a combination of between three and ten carbon atoms and zero to four heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur, and combinations thereof. Some examples of such inhibitors include, but are not limited to, poly(N-ethylacrylamide), poly(N,N-diethylacrylamide), poly(N-methyl, N-acrylamide), poly(iso-propylacrylamide), poly(n-propylacrylamide), poly(N-cyclopentylacrylamide), poly(N-cyclohexylacrylamide), poly(acryloylpiperdine), poly(acryloylpiperdine), poly(acryloylmorpholine) and various N-substituted acrylamide copolymers.

摘要： A method of transporting a mixed phase fluid in a conduit. A hydrate and/or wax film is permitted to deposit on an inner wall of the conduit in a conversion zone, the conversion zone being less than a length of the conduit. A quantity of heat is applied to the conduit in the conversion zone until the hydrate and/or wax deposited on the inner wall in the conversion zone separates therefrom, thereby inhibiting the continual formation of hydrates and/or wax on the inner wall. The separated hydrates and/or wax are flowed in the mixed phase fluid.

摘要： Methods and systems are provided for producing hydrocarbons from production fluids that have water as an external phase. A method for transporting a hydrocarbon through a pipeline includes injecting water into a production stream at a production center. The production stream includes a hydrocarbon, and the water injection forms a transportation stream that includes a water external phase. The transportation stream is flowed through a transportation line to a surface facility, wherein the transportation line comprises a plurality of static mixers spaced at intervals along the transportation line.

摘要： Methods and systems are provided for inhibiting the formation and/or growth of clathrate hydrates in a mixed phase fluid at or near the walls of a tubular through use of a chemical or physical coating on the tubular wall. An exemplary embodiment provides a method for producing a flowable mixed phase fluid having the potential to create clathrate hydrates. The method includes inhibiting hydrate formation in a tubular by injecting an additive into a fluid stream in the tubular, and the additive adheres, at least in part, to the walls of the tubular and inhibits hydrate growth proximate to the wall. When sufficient additive is injected into the tubular system, the hydrate film growth on the tubular walls is inhibited, at least to some extent, and a continuous flow rate is maintained.

摘要： The present techniques are directed to a pipeline transporting a production fluid including hydrocarbon. An optical fiber is disposed along a length of the pipeline. A control system determines a predicted operating temperature based on pressure and flow rate of the production fluid in the pipeline. The control system determines a measured temperature along the pipeline using the optical fiber. The control system detects and locates a temperature anomaly by comparing the measured temperature of the pipeline to the predicted operating temperature.
