Benefits of technology
This patent describes a system that allows a sensor to directly know the position of a moveable part in equipment used in hydrocarbon drilling and production. This includes a housing with a body and an inner cavity where the moveable part is located. A sensor assembly is positioned within the housing, and an indicator feature is on the moveable part. When the moveable part is in its set position, the sensor assembly will sense it and provide a signal that corresponds to its position. This signal can be used to inform the operator and provide specific notifications. The technical effect of this system is that it provides a more accurate and efficient way to know the position of a moveable part in hydrocarbon drilling and production equipment.
Problems solved by technology
These methods of position indication are limited in accuracy because the indirect position of the moveable member is estimated by measuring the movement of other components that move in conjunction with such moveable member.
As such, there are uncertainties in the true position of the moveable member.
If the connection between the moveable member and the components that move in conjunction with such moveable member are loose, worn, fail or are otherwise not easily evaluated, the position indicator may provide a false indication of the position of the moveable member.
However, this method is impractical due to visibility issues and the required sight glass thickness to provide sufficient structural integrity.

A system for directly sensing a position of a movable part of a hydrocarbon drilling and production includes a housing having a body with an inner cavity and a body wall with a wall thickness defined between an inner surface of the inner cavity and an outer surface of the body. The inner cavity has a fluid flow path for hydrocarbon development fluids. A moveable member is located within the inner cavity. A sensor assembly is located within one of the body wall and the moveable member, the sensor assembly being positioned within a port. An indicator feature is on the other of the body wall and the moveable member, the indicator feature sensable by the sensor assembly when the moveable member is in a set position.
Description
BACKGROUND[0001]1. Field of Disclosure[0002]The present disclosure relates in general to equipment used in hydrocarbon drilling and production operation, and more particularly to sensing the location of components used in such equipment.[0003]2. Description of Related Art[0004]In hydrocarbon drilling and production operations, it can often be desirable to determine a location of moveable members within a piece of equipment. As an example, hydraulic and pneumatic actuated valves used in hydrocarbon drilling and production equipment typically consist of a top shaft or limit switch mounted on the actuator for position indication of the valve member, such as a gate. In other examples, the position of a manual valve with a rotatable shaft can be estimated based on the number of turns made by a hand wheel, or using a thread indicator that moves in conjunction with the valve stem. In yet other examples, a length of tubular member extending from a well can be used to estimate how far into a...
