20090151936 | System and Method for Monitoring Scale Removal from a Wellbore - A technique enables the cleaning of scale from a well and the monitoring of scale removal. A scale removal tool and a radiation detector are deployed simultaneously into a wellbore having scale with a radioactive signature. The scale removal tool is used to remove deposits from a well component, e.g. from the interior of a tubular member. The radiation detector enables the measuring and monitoring of scale removal. Data related to the scale removal can be output for use by an operator to help optimize scale removal and fluid flow. | 06-18-2009 |
20090288822 | MITIGATION OF ELEMENTAL SULFUR DEPOSITION DURING PRODUCTION OF HYDROCARBON GASES - Methods of producing a sour hydrocarbon gas via production tubing intersecting a reservoir, are described, one method including contacting an underground reservoir with an aqueous composition optionally comprising an additive, the reservoir comprising hydrocarbons and sulfur compounds; displacing the composition into the reservoir by forcing a fluid (which may be a non-hydrocarbon gas, or inert gas, or nitrogen, or argon, or mixture thereof), into the reservoir, or into the production tubing; and producing at least some of the hydrocarbons and sulfur compounds from the reservoir through the production tubing, the composition wetting the production tubing and preventing substantial deposition of elemental sulfur thereon. | 11-26-2009 |
20100300684 | CONTINUOUS DOWNHOLE SCALE MONITORING AND INHIBITION SYSTEM - A technique facilitates monitoring of conditions which are prone to cause scale precipitation around downhole equipment. The technique also enables a local, downhole reaction to the potential for precipitation of scale. A downhole scale monitoring and inhibition system may be provided with a measurement module and injection module. The measurement module monitors at least one downhole parameter indicative of the potential for scale formation. In response to data output from the measurement module, the injection module is operated to provide downhole, local injections of an inhibitor chemical. | 12-02-2010 |
20110277995 | APPARATUS AND METHOD FOR MONITORING CORROSION AND CRACKING OF ALLOYS DURING LIVE WELL TESTING - A tool string sub. A longitudinally extending tubular housing has an outside surface and an inside surface. A stepped circumferential portion of the inside surface of the housing bisects the interior surface of the housing. A degradation part is connected adjacent to the stepped portion of the housing and is supported by the housing and at least one moveable support part protruding inward and beyond the inner surface of the housing. The support part has a first position where the degradation part is at one stress and a second position where the degradation part is at a second stress greater than the first stress. At least one end of the tool string sub is adapted to connect with a tool string. | 11-17-2011 |
20130008649 | METHOD AND MODULE FOR DETERMINATION OF EROSION IN SYSTEMS - A method of providing information regarding erosion in an oil and/or a gas production system, which system includes at least one equipment/piping, the method including the steps of obtaining CFD results regarding hot spots in the equipment/piping from a CFD analysis of the equipment/piping for a range of pressures, flow rates and sand rates; and to, during production, obtaining data regarding erosion rates in a particular location in the system; and combining the data regarding erosion rates and CFD results to estimate and monitor sand erosion rates in the hot spots of the system. Further disclosed is a module performing the method steps as well as a computer program. | 01-10-2013 |
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 |
20160160598 | METHOD OF CLOSING A BLOWOUT PREVENTER SEAL BASED ON SEAL EROSION - A method of sealing a wellbore with a blowout preventer (BOP) is disclosed. The method involves providing the BOP with a BOP seal. The BOP has BOP parameters and a fluid flowing through the BOP has fluid parameters. The method also involves simulating erosion of a BOP seal using a BOP model based on the BOP parameters and the fluid parameters, measuring erosion of the blowout preventer seal by performing a lab test of the blowout preventer seal in a tester according to the blowout preventer model, validating the simulating by comparing the simulated erosion with the measured erosion, determining an erosion rate of the blowout preventer seal based on the validated simulating, defining closing parameters based on the determined erosion rate, and operating the blowout preventer rams according to the defined closing parameters | 06-09-2016 |
