Abstract: A system for monitoring a position of a pipe joint as the pipe joint moves through a production system along a longitudinal axis of a wellbore of the production system includes an ultrasonic sensor configured to detect the pipe joint. The system also includes a controller configured to receive a signal from the ultrasonic sensor. The controller includes a processor configured to determine a first position of the pipe joint along the longitudinal axis at a first time based on the signal. The processor is further configured to determine a displacement from the first position of the pipe joint, and to determine a second position of the pipe joint along the longitudinal axis at a second time based on the displacement. The controller also includes a memory configured to store the first position and the second position.

Abstract: An early kick detection system including a kick detection computing device coupled to at least one sensor associated with a drilling system of a well. The kick detection computing device is configured to receive measurement data from the at least one sensor. The measurement data includes one or more kick indicators used to identify a well kick. The kick detection computing device generate an estimated value for each of the one or more kick indicators during simulated normal drilling conditions and simulated kick conditions. The kick detection computing device determines a deviation value and generates a signal based on the deviation value. The signal activates a green status, an amber warning, or a red alarm to indicate a kick detection status of the drilling system.

Abstract: A process for preparing a bimodal emulsion of viscous hydrocarbon in water includes providing a stream of water at ambient temperature; providing a liquid additive that tends to gel when mixed with water at temperatures less than a gelling temperature TG; heating the stream to provide a heated stream at a temperature TC which is greater than ambient temperature and less than the gelling temperature TG; feeding the heated stream to a mixer having a mixer inlet so as to impart energy to the heated stream; adding the liquid additive to the heated stream downstream of the mixer inlet, whereby the liquid additive mixes with the stream and the energy inhibits gelling of the liquid additive to provide a substantially homogeneous solution of additive in water. The solution is then divided and used to make two different droplet sized emulsions which are mixed to form the bimodal emulsion.
