Abstract: Methods and apparatus for diverting fluids either into or from a well are described. Some embodiments include a diverter conduit that is located in a bore of a tree. The invention relates especially but not exclusively to a diverter assembly connected to a wing branch of a tree. Some embodiments allow diversion of fluids out of a tree to a subsea processing apparatus followed by the return of at least some of these fluids to the tree for recovery. Alternative embodiments provide only one flowpath and do not include the return of any fluids to the tree. Some embodiments can be retro-fitted to existing trees, which can allow the performance of a new function without having to replacing the tree. Multiple diverter assembly embodiments are also described.

Abstract: A process for disrupting filter cake in an underground formation, which process comprises: (i) incorporating into a treatment fluid a solid polymer capable of being converted by hydrolysis into one or more organic acids; (ii) introducing the treatment fluid into the underground formation; and (iii) allowing the solid polymer to hydrolyse in the presence of water to produce organic acid such that acid soluble material within the filter cake or adjacent formation is dissolved.

Abstract: The invention relates to an apparatus and method to obtain a bitumen or heavy oil sample from an oil reservoir sample, such as a core sample, to enable measurement of physical properties such as viscosity, API gravity, or chemical properties such as sulphur content of the obtained bitumen or heavy oil sample. The analyses performed on the samples obtained in accordance with the invention are effective in assisting oil field operators in making timely drilling and production decisions at the oil reservoir or for routine laboratory extraction of oils and bitumens. The invention also permits the collection of samples from simulated thermal recovery operations and also allows the collection of bitumens and oils for online analysis of live oil physical properties.

Abstract: Techniques for determining viscosity of oil in a sample include extracting the oil from the sample using a volatile polar first solvent; using a portion of the extracted oil to determine a concentration factor of oil in the sample; determining a dry weight of the extracted oil using the concentration factor; adding a second solvent to a remaining portion of the extract, where the second solvent is less volatile than the first solvent; removing the first solvent from the remaining portion of the extract; taking a series of sub-samples from the remaining portion of the extract and sequentially removing different amounts of the second solvent from each sub-sample; measuring solvent concentrations and viscosity values of the solvent-oil mixtures of each sub-sample; and based on the measured solvent concentrations and viscosity values of each sub-sample, determining the second-solvent-free viscosity of the oil in the sample.
