Abstract: A monitoring tool is provided for monitoring wells for flow anomalies. The temperatures of flowing well fluid and ambient temperature are monitored and various methods applied to indicate if a well is flowing as expected, is flowing less than expected and, therefore, at risk of flow stoppage, not flowing or calculation of flow rate when the well is flowing less than expected. Approaches are described for determining trending indicators from actual flow temperatures compared to a normal flow relationship for establishing the presence of flow anomalies. Temperature sensors, onsite processors and communications upload data for display of well status flags on a mapping module enabling pro-active detection and preventative action by operators.

Abstract: Make-up speed for a tongs drive system is monitored and controlled to maintain the speed within a limited target range either throughout the make-up process or during the final portion of the make-up process, thereby improving make-up consistency and allowing for improved evaluation or torque during the make-up process. An encoder generates speed and position data during the make-up process. The speed data is compared to a target speed, which is based on rod and/or tongs characteristics. If the speed does not match the target speed or is not within a range of the target speed, a signal is transmitted to the tongs drive to adjust the speed accordingly. Furthermore, position data from the encoder, or other position sensors, provide position data for the rod during the make-up process to limit or vary the speed control parameters during different portions of the make-up process.

Abstract: Efficiency of a hydraulically driven system is evaluated by monitoring the change in ratio of output torque to input hydraulic pressure. The hydraulic pressure data is received from a hydraulic sensor. The torque data is received from a load cell receiving a force transmitted to it by a back-up wrench. Filters are applied to the data to obtain peak levels of torque and hydraulic pressure. A ratio is generated for each process associated with a rod or other elongated member based on peak torque and hydraulic pressure levels achieved during the process. The ratio is stored and compared to historical ratios to determine if the ratio has changed more than a predetermined amount over time. A similar evaluation can be achieved by comparing speed generated on the elongated member by the hydraulically driven system to the current level controlling the floss of hydraulic fluid to the hydraulically driven system.

Abstract: An apparatus, system and methodology enable non-intrusive measurement of parameters related to fluid flow in a conduit. An acoustic sensor is located along the conduit and includes a mechanical amplifier having an acoustic input coupled to the conduit and a microphone coupled to the mechanical amplifier. The microphone receives mechanically amplified acoustic energy from the conduit and establishing first signals which are processed for generating second signals which are related to fluid flow in the conduit. The second signals can include quantitative flow data and qualitative data such as change in state and alarms. The second signals can be transmitted wirelessly to a remote site for further processing. Use of low power components and power management enable long term operations on battery power.
