20100051265 | Firing trigger apparatus and method for downhole tools - Methods and devices are provided for controlling detonation of explosives in a well bore for perforation or a well bore casing, which avoid or reduce unintentional or undesirable detonations while ensuring or increasing desirable detonations. An explosive trigger system or tool may comprise a central processing unit (CPU), memory, and one or more sensors disposed for measuring one or more downhole conditions. Downhole conditions may be measured with the sensor and then used to program detonation parameters (such as temperature or pressure) or preconditions (such as time or distance traveled) to the trigger system. Detonation can only occur when the programmed parameters or preconditions are satisfied. In this way, undesirable detonations are avoided by requiring certain preconditions to arming the trigger system. To further control arming and/or detonating, a line sequencer may be provided, wherein energy is propagate down along the physical deployment line as pulses or line “jerks” through mechanical manipulations of physical deployment line near surface. These pulses can form signals for downhole control of the trigger system. | 03-04-2010 |

20100051440 | Perforation gun pressure-actuated electrical switches and methods of use - Pressure-actuated electrical switches are provided that comprise a housing having a slidable piston therein. The slidable piston slides from a first position to a second position and in so doing switches an electrical path from a first electrical contact and a second electrical contact to an electrical path between the first electrical contact and a third electrical contact. Suitable applications of such switches include any application in which a pressure wave is used to actuate an electrical switch. The pressure-actuated electrical switches of the present invention are especially adapted for use in controlling successive detonations in a downhole perforation gun, as explosive gases and pressure waves are used to actuate the slidable piston so as to trigger a subsequent detonation charge. Perforation guns utilizing these pressure-actuated electrical switches and corresponding methods of use are also provided herein. | 03-04-2010 |

20120251335 | PUMP CONTROLLER WITH MULTIPHASE MEASUREMENT - Methods and apparatus for measuring phase flow rate of the components of a multiphase fluid in a conduit. A pumping system pumps out a multiphase fluid from a wellbore. At least one processor, which may also control the pump, is used to determine the total liquid flow rate over time. An optical phase fraction meter (e.g., an infrared filter photometer) is used to determine the real-time phase fraction of the components of the multiphase fluid. Algorithms are used to calculate the volumetric flow rates of the individual components of the multiphase fluid based upon the total liquid flow rate and the phase fraction. Embodiments of the present invention provide an inexpensive system capable of measuring real time water-to-oil ratios in mature fields, where the water-to-oil ratio is high and the oil per-well production is low. | 10-04-2012 |

20100294922 | Automated calibration methodology for VUV metrology system - A calibration pad having multiple calibration sites is provided. A particular calibration site may be utilized until that particular site has been determined to have become unacceptable for further use, for example from contamination, in which case the calibration processes may then move to use a different calibration site(s) on the calibration pad(s). A variety of techniques may be utilized to provide the determination that a site is no longer acceptable for use. Movement may thus occur over time from site to site for use in a calibration process. A variety of criteria may be established to determine when to move to another site. Though the designation of a site as “bad” may be based upon measured reflectance data, other criteria may also be used. For example, the number of times a site has been exposed to light may be the criteria for designating a site as bad. Alternatively the cumulative exposure of a site may be the criteria. Further, the plurality of calibration sites that are provided on the single calibration pad may be pre-evaluated so as to initially screen out unacceptable calibration sites prior to use. The techniques provided may be utilized in calibration processes which utilize a single calibration sample or processes which require a plurality of calibration samples. | 11-25-2010 |
