  • Publication number: 20200069651
    Abstract: The present invention is directed to compositions and methods for treating ocular conditions, including presbyopia, mild hyperopia, irregular astigmatism, hyperopic accommodative esotropia, and glaucoma. The compositions can also be used to potentiate or enhance interventions that retard, reverse, or modify the aging process of the crystalline lens and its surrounding tissues. The compositions include a cholinergic agent, such as a muscarinic acetylcholine receptor M3 agonist, and an alpha agonist having an imidazoline group or a non-steroidal anti-inflammatory agent (NSAID) having COX-2 selectivity. It has been found that an alpha agonist having an imidazoline group or non-steroidal anti-inflammatory agent (NSAID) having COX-2 selectivity in combination with a cholinergic agent, such as pilocarpine, act synergistically to improve the accommodative and focusing ability of the eye while minimizing the side effects from each compound.

  • Patent number: 9085975
    Abstract: A method of treating a subterranean formation penetrated by a wellbore is carried out by preparing a treatment fluid at a surface location based upon an initial model of fluid properties for the treatment fluid. The treatment fluid is formed from a first fluid stream and at least one additive fluid stream that are combined to form a treatment fluid stream that is introduced into the wellbore in a substantially continuous process. A fluid property of at least one of the streams is monitored while forming the treatment fluid to provide at least one monitored fluid property of the at least one of the streams. The model is updated based upon the at least one monitored fluid property during the substantially continuous process. Optionally, at least one of the first fluid stream and the at least one additive stream is adjusted as necessary based upon the updated model.

  • Patent number: 9023280
    Abstract: A system and method for determining the asphaltene content of a downhole oil sample are provided. In one example, the method includes obtaining a hydrocarbon sample from a hydrocarbon formation of a reservoir at a given depth using a downhole tool. A liquid phase of the hydrocarbon sample is isolated within the downhole tool and the liquid phase is subjected to downhole analysis within the downhole tool to create a chromatography sample. The downhole analysis is based at least partially on size exclusion chromatography. A first property of the chromatography sample is measured to obtain a measured value, and a second property of the chromatography sample is estimated based on the measured value and known calibration curves.
