20080240930 | Method and System for Optimizing Downhole Fluid Production - A method and system for pumping unit with an elastic rod system is applied to maximize fluid production. The maximum stroke of the pump and the shortest cycle time are calculated based on all static and dynamic properties of downhole and surface components without a limitation to angular speed of the prime mover. Limitations of structural and fatigue strength are incorporated into the optimization calculation to ensure safe operation while maximizing pumped volume and minimizing energy consumption. Calculated optimal prime mover speed is applied to the sucker rod pump by means of beam pumping, long stroke or hydraulic pumping unit by controlling velocity, acceleration and torque of the electric prime mover or by controlling pressure and flow rate in hydraulically actuated sucker rod pumping system. | 10-02-2008 |
20130030721 | SYSTEM AND METHOD FOR DETERMINATION OF POLISHED ROD POSITION FOR RECIPROCATING ROD PUMPS - A system and method for measurement of a polished rod movement in a reciprocating rod pumping system comprising reciprocal motive elements is provided. A proximity sensor target is mounted on the polished rod while a corresponding sensor element, is mounted in fixed relation to the pumping system, for example in fixed relation to the wellhead or ground. The sensor detects passage of the proximity sensor target, and thus the polished rod, as it moves in opposite directions during a single stroke cycle. The time of passage and the speed of the polished rod, as determined from its kinematic relationship with other pumping system components, is used to determine the position of the polished rod at any point during the cycle. The proximity sensor target may be mounted on a walking beam or other reciprocally moving element, with the sensor positioned in a corresponding fixed location. | 01-31-2013 |

20130277063 | SYSTEM AND METHOD OF IMPROVED FLUID PRODUCTION FROM GASEOUS WELLS - A system and method are provided for improving hydrocarbon production from gaseous wells, and in particular improving hydrocarbon production using pumping systems employing artificial lifts. The pumping system of the well is controlled so as to cyclically decrease and increase gas pressure in the casing annulus, thus cyclically decreasing PBHP in response to the decrease in the casing annulus pressure and permitting the PBHP to increase in response to the increase in casing annulus pressure. Production of fluid from the reservoir is therefore increased during the cyclical decrease in casing annulus pressure, and production of fluid from the downhole pump is increased during the cyclical increase in casing annulus pressure. In addition, gas interference due to production of foam in the casing surrounding a downhole pump can be mitigated by forcing liquid from the foam during the period of increased casing annulus pressure. | 10-24-2013 |

20120124671 | SYSTEMS AND METHODS FOR IDENTIFYING AND MITIGATING INFORMATION SECURITY RISKS - Methods and systems for Sustained Testing and Awareness Refresh against Phishing threats (STAR*Phishâ„¢) are disclosed. In an embodiment, a method assigns schemes and unique identifiers to target e-mail addresses associated with a user accounts. The method delivers e-mail messages to the targeted e-mail addresses, the e-mail messages comprising an HTTP request and a unique identifier associated with each of the user accounts. The method then receives, at a Phishing Metric Tool (PMT), a response including the unique identifier. The PMT logs training requirements for the user accounts, tracks response metrics for the training requirements, and redirects the respective HTTP requests to a phishing training tool (PTT). The PTT sends a notification of the user account identities and the unique identifiers to the PMT and returns a status for the training requirements for the user accounts. Upon completion of the training, the PMT sends completion notifications for the user accounts. | 05-17-2012 |
