| 261 | WELLHEAD FLOWLINE PROTECTION SYSTEM | US15217414 | 2016-07-22 | US20180023360A1 | 2018-01-25 | Patrick S. Flanders; Abdelghani Daraiseh |
| A system and method for the application of differential pressure indicating transmitters in conjunction with pressure sensors, pressure transmitters and position switches to monitor and control the flowline protection systems at remote wellheads. The system communicates with a local control panel in proximity to the wellhead, as well as to a central control room at the processing plant supplied by the wells. The system provides a black box data recorder function that documents every system test, valve closure, and the ability of the independent protection layers to contain the wellhead topside pressure. In addition, the system provides a means to limit release of hydrocarbons via a conventional pressure relief and flare system, and documents high pressure events when pressure relief valve setpoints are reached. | ||||||

| 267 | Control line sharing between a lower and an insert safety valve | US14298094 | 2014-06-06 | US09739116B2 | 2017-08-22 | Charles T. Kirkpatrick |
| A system involving a lower tubing mounted safety valve having one or two control lines further contains a landing nipple above for a wireline insert valve. One line that serves the lower safety valve is tied to a connection on the landing nipple for the insert valve. When the lower safety valve malfunctions the landing nipple wall is penetrated to get communication to the line coming from the lower safety valve so that such line can serve as a balance line for the insert valve. The other line from the surface to the other connection on the landing nipple serves as the operating line for the insert valve. Making one line serve a dual purpose eliminates one control line from the surface. | ||||||
