20100089142 | PROCESS UTILIZING NATURAL CARBON-13 ISOTOPE FOR IDENTIFICATION OF EARLY BREAKTHROUGH OF INJECTION WATER IN OIL WELLS - This invention relates to a process utilizing natural carbon-13 isotope for identification of early breakthrough of injection water in oil wells. All natural water sources are labeled by unique ratios of carbon isotopes ( | 04-15-2010 |
20100107753 | METHOD OF DETECTING A LATERAL BOUNDARY OF A RESERVOIR - A method of detecting a lateral boundary of a compacting or expanding region in a subsurface formation, which method comprises determining non-vertical deformation of the earth' s surface above the subsurface formation over a period of time; identifying at least on contraction area and at least one adjacent dilatation area of the earth' s surface from the non-vertical deformation over the period of time; and using the contraction area and the adjacent dilatation area as an indication of a lateral boundary of the compacting or expanding region; and a method for producing hydrocarbons. | 05-06-2010 |
20100242586 | IN-SITU FLUID COMPATIBILITY TESTING USING A WIRELINE FORMATION TESTER - A method for performing fluid influx tests in a wellbore ( | 09-30-2010 |
20140165715 | Methods and Apparatus for Determining Downhole Parameters - Example methods and apparatus for determining downhole parameters are disclosed herein. An example method includes pumping a fluid in a first direction to substantially fill a first area of a fluid flow passageway with the fluid and determining a fluid parameter via a sensor disposed in a second area adjacent the first area. The sensor includes a heater and a temperature sensor. The example method also includes determining if the first fluid has flowed in a second direction into the second area based on the fluid parameter. | 06-19-2014 |
20150007649 | METHOD FOR TESTING THE TIGHTNESS OF CAVITIES AND DEVICE FOR DECREASING CONVECTION AND DIFFUSION FLOW - The present invention relates to a method for testing the tightness of cavities, which are already filled with a stored gas, by charging the with a test gas. At least the following steps are provided: overlayering the stored gas situated in the cavity with a test gas of a predefined amount, in such a manner that a barrier layer forms between the stored gas and the test gas, wherein the test gas has a lower density than the stored gas, releasing the test gas after a predetermined time, and balancing the amount of the test gas. A further aspect is providing a device for decreasing the convection and diffusion flow between a stored gas situated in a cavity and a test gas. | 01-08-2015 |
20150013447 | METHOD AND APPARATUS FOR IN-SITU FLUID INJECTOR UNIT - Disclosed is a method of testing liquids at a test pressure. A first fluid is placed in a first chamber of a test system. The first fluid is brought to the test pressure. A volume is calculated of a second fluid to inject into the first chamber from a second chamber of the test system via a first portion connecting the first chamber and the second chamber. The first portion includes a fluid interface between the first fluid and the second fluid located in the first portion. The volume of the second fluid is injected into the first chamber, displacing an equivalent volume of fluid into a third chamber of the test system via a second portion connecting the first chamber and the third chamber in fluid communication with each other. The volume of the second fluid in the first chamber is mixed with a remaining volume of the first fluid in the first chamber to create a combination fluid. The combination fluid is tested. | 01-15-2015 |
20150143887 | FLUID LOSS CONTROL MATERIAL TESTER - A method for testing a loss control material, the method including filling a testing environment in a testing system with a first fluid, injecting a loss control material in a second fluid into the testing environment from a first end of the testing system, thereby displacing the first fluid across the testing environment to a second end of the testing system, and monitoring a formation of a barrier created by the loss control material. | 05-28-2015 |
