20130087328 | Downhole Species Selective Optical Fiber Sensor Systems and Methods - A disclosed downhole optical sensor system includes at least one optical sensor positioned in a borehole and coupled to an interface via a fiber optic cable. Each of the optical sensors includes a waveguide for conducting light, and a reagent region positioned between the waveguide and a fluid in the borehole to absorb a portion of the light from the waveguide, the portion being dependent upon a concentration of a chemical species in the fluid. A described method for operating a well includes deploying one or more downhole optical sensors in a fluid flow path in the well, probing the one or more downhole optical sensors from a surface interface to detect concentrations of one or more chemical species, and deriving a rate of scale buildup or corrosion based at least in part on the detected concentrations. | 04-11-2013 |
20130245947 | DOWNHOLE SYSTEMS AND METHODS FOR WATER SOURCE DETERMINATION - A disclosed system for determining sources of water in a downhole fluid includes one or more downhole sensors that measure at least one analyte concentration in the downhole fluid, and a computer having analyte concentration characteristics for water from multiple sources. The computer uses the analyte concentration characteristics and the at least one analyte concentration measurement to determine an amount of water from at least one given source. A described method for determining sources of water in a downhole fluid includes associating with each of multiple sources of water a characteristic concentration of at least one analyte, obtaining measured concentrations of the at least one analyte with one or more downhole sensors, and deriving for at least one source of water a fraction of the downhole fluid attributable to that at least one source. The deriving may also be based upon measurements from distributed pressure and/or temperature sensors. | 09-19-2013 |

20090176741 | MODULATION OF THE IMMUNE SYSTEM BY INOSITOL PHOSPHOLIPIDS - The invention relates to the field of immunology. More specifically, it relates to methods and compositions to suppress the immune system, among other by interference with antigen-presenting molecules and T-cell activation. Provided is a composition for the prevention or treatment of a condition wherein suppression of T cell activation is desirable, comprising as an active ingredient an inositol phospholipid or a pharmaceutically acceptable salt thereof. Said condition can be an auto-immune disease, allergic disorder or chronic inflammatory disease, for example asthma, diabetes Type I, rheumatoid arthritis (RA) or inflammatory bowel disease (IBD). Also provided is a food item or food supplement having immunomodulating properties, comprising an effective amount of an inositol phospholipid. | 07-09-2009 |
