Abstract

Certain aspects of the present disclosure provide for wireless sensor packages to monitor various oilfield equipment health status, such as bearing wear and detect out-of-balance condition on reciprocating rod lifts (RRLs). Equipment health data can be collected, analyzed and stored by an IoT gateway, which is a small form-factor, ruggedized, low-power Intel processor computer running a novel message-oriented middleware software stack that leverages the MQTT protocol. Data may subsequently be transmitted to a cloud service via the internet via to a datacenter through SCADA, for analysis and action.
