Abstract: A wearable training apparatus has a vision-control assembly and a head-mounting assembly coupled to the vision-control assembly. The vision-control assembly has a see-through area corresponding to a central portion of the human field of vision (FOV), and a vision-blocking area for blocking the human peripheral FOV except the central portion thereof. The wearable training apparatus may be in the form of a pair of eyeglasses with lenses provided with reduced FOV or alternatively, may be in the form of a goggle with reduced FOV. A training system may comprise one or more wearable training apparatus, one or more imaging devices for recording images and/or video streams of the performance of users wearing the training apparatuses, and one or more computing devices for playing back and analyzing the recorded images and/or video streams.

Abstract: A method to pre-treat an inlet natural gas stream at gas pressure reduction stations to produce LNG removes water and carbon dioxide from a natural gas stream. The energy required for the process is provided by recovering pressure energy in the inlet gas stream. The process eliminates the conventional gas pre-heating process at pressure reductions stations employing gas combustion heaters. The process provides a method to produce LNG at natural gas pressure reduction that meets product specifications.

Abstract: A method and system for servicing a well. Servicing a well often includes running a service string into a production string, which may include a rod string. A service portion is provided in the production string during completion. The service portion is located at or uphole of a large rod string feature. The service portion has a greater inside diameter than production tubing and other standard production string components. The service portion provides sufficient clearance for the service string alongside the large feature. The large feature may be, for example, a PCP stator, a centralizer, or a rod collar. The large feature may be pulled uphole into the service portion prior to running in the service string, allowing servicing downhole of the large feature without pulling the entire rod string. The service portion may also mitigate rod wear in deviated or other portions of the well.

Abstract: A method of producing temperature and pressure conditioned fluids using a fuel cell. The fuel cell generates an anode exhaust stream of water vapour and carbon dioxide. The water in the exhaust stream is condensed and separated to produce a stream of water and a stream of carbon dioxide. A first portion of the stream of water is heated to produce a stream of steam, which is combined with the fuel to form the anode input stream. A stream of condensed carbon dioxide is obtained by condensing at least a portion of the carbon dioxide in the stream of carbon dioxide. At least one fluid is heated and compressed to a target temperature and pressure for each fluid, the at least one fluid comprising a second portion of the stream of water or at least a portion of the condensed carbon dioxide.
