摘要： A hydraulic accumulator system is provided to remove the motors or engines from the red zone while maintaining sufficient capacity within the red zone to quickly close the designated blowout preventer or other gate valves. Additionally, a single point is provided outside of the red zone to charge the local storage units or to open or close the designated blowout preventer or other gate valves when time is not a critical consideration.

摘要： A sensor system to prevent the unintended severing or damage to a cable or other object within the throughbore of a standpipe or wellhead that may include a blowout preventer and gate valves. Generally, a sensor which may include both an emitter and receiver, is affixed externally to the standpipe, wellhead, blowout preventer, or gate valves. None of the emitter or receiver penetrates the pressure vessel formed by the standpipe, wellhead, blowout preventer, or gate valves. The sensor system may detect disturbances in a pre-existing field such as a geomagnetic sensor detecting the earth's magnetic field, the sensor may create a field and then detect disturbances within that created field such as a magnetic sensor, or the sensor may send a pulse of energy towards the area to be sensed and then read the reflected energy. Generally, the sensor system includes a logic controller, a memory, a sensor or sensors that may or may not include emitters and receivers, and a display. I

摘要： A sensor system to indicate whether or not the gate valve is open, closed, or at some position between. In certain instances, two sensors may be used to indicate the position of an attachment to the gate within the gate valve thereby indicating whether or not the gate within the gate valve is fully opened or fully closed. In other instances, a single sensor may be utilized to indicate the position of an attachment to the gate within the gate valve such position being between and including fully opened and fully closed. Generally, a sensor which may include both an emitter and receiver, is affixed externally of the pressurized portion of the gate valve or other type of valves. The sensor system may detect disturbances in a pre-existing field such as a geomagnetic sensor detecting the earth's magnetic field, the sensor may create a field and then detect disturbances within that created field such as a magnetic sensor, or the sensor may send a pulse of energy towards the area to be sensed and then read the reflected energy. Generally, the sensor system includes a logic controller, a memory, a sensor or sensors that may or may not include emitters and receivers, and a display.

摘要： A greasing system may be placed partially within the red zone and partially outside of the red zone. Grease and pneumatic power is supplied from outside of the red zone to a pod, inside of the red zone, having local storage, high-pressure pumping capacity, and a distribution mechanism. The grease is supplied from outside of the red zone to the pod at low-pressure through a hose having at least a 1 inch inside diameter and is usually at least 100 feet long. The pod pressurizes the grease to a high-pressure and distributes the grease via a distribution mechanism to a relatively short hose, generally less than 8 feet between the distribution mechanism and the greasing point on the wellhead, in order to minimize pressure losses.

摘要： A check valve bleed assembly eliminates the requirement for a person to enter the red zone when bleeding the grease out of a gate or other valve. A gas or other fluid is provided to the check valve bleed assembly. The gas or other fluid acts upon the surface driving a pin into the associated check valve with sufficient force to overcome the resistance of the object sitting on a seat and moves the object off of the seat. The force is maintained as long as is necessary. Usually, the check valve is held open until the gate transitions into the gate's associated gate recess thereby displacing the grease within the gate recess through the check valve, into the check valve bleed assembly, and finally to a waste collection tube. In some embodiments a gate valve greasing access port is included in the check valve bleed assembly such that grease may be injected into the check valve bleed assembly.

摘要： A wellhead is provided having a port or ports about the external periphery of the wellhead. The center bore of each port is generally directed at a point within the wellhead having a location where a portion of a tool or an object is expected. Each port does not provide fluid access from the exterior to the interior of the wellhead and preferably has a flat bottom. Each port is fitted with a sensor and preferably the sensor contacts the bottom of the port. And ultrasonic a sensor emits an ultrasonic waveform which proceeds through the bottom of the port and a portion of the ultrasonic waveform is reflected back to the ultrasonic receiver. A comparison is then performed to compare the predicted value versus the received value to determine whether or not the expected tool or object is in place or partially in place within the wellhead.
