摘要： Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.

摘要： A natural gas hydrate inhibitor having a structure of formula (1) or formula (2). The inhibitor of the present invention is synthesized on the basis of N-vinylpyrrolidone by introducing a new structural group to achieve terminal modification of the polymer chain, which thereby improves the inhibitory effect. wherein R is a C1-8 hydrocarbon group.

摘要： A method of starting up flow of viscous oil in a pipeline, wherein the pipeline has an inlet and an outlet and wherein the viscous oil is initially stationary within the pipeline, includes supplying water to a first section of the pipeline through an inflow control device; initiating a flow of viscous oil within the first section towards the outlet by pressurising the water; supplying water to a second section of the pipeline through a further inflow wherein the first section is closer to the outlet of the pipeline than the second section; and initiating a flow of viscous oil within the second section towards the outlet by pressurising the water.

摘要： A production method can include flowing a heterogeneous fluid mixture into contact with a homogenizing cutting tool, measuring a fluid mixture temperature so as to obtain a measured fluid mixture temperature, and determining a target fluid mixture temperature. The fluid mixture can be frictionally heated so as to obtain a heated and homogenized fluid mixture by driving the cutting tool at a rate based on (i) the target fluid mixture temperature and (ii) the measured fluid mixture temperature. The heated and homogenized fluid mixture can be flowed away from the cutting tool.

摘要： Nanoparticles may be used in the formulation of long chain poly-alpha-olefins, commercially known as Drag Reducer Additives (“DRA”). These nanoparticles may be embedded in the original DRA formulation and/or added at some point in the pipeline application so they can then be used to destroy the DRA polymer by cleaving, interrupting or restructuring the DRA or otherwise breaking its bonds or to agglomerate or coagulate the polymer so it can be removed mechanically or chemically.

摘要： The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.
