摘要： A method for monitoring and optimizing stimulation operations in a reservoir. In particular, the method utilizes a downhole telemetry system, such as a network of sensors and downhole wireless communication nodes, to monitor various stimulation operations. Data signals are transmitted acoustically through the tubular. Communication nodes comprise an elongated body that supports one or more power sources (230) and an electro-acoustic transducer (242).

摘要： A use of a foulant collector in a vessel or conduit in a paraffinic froth treatment (PFT) process. The foulant comprises asphaltenes. The foulant collectors are purposed to reduce build-up in the vessel or conduit and/or to reduce downstream foulant carry-over in the process. The surface of the foulant collectors may have an average water contact angle of less than 90 degrees. Additionally, together with such foulant collectors, a fluorocarbon polymer may be used as a surface of a vessel or conduit in the PFT process, for reducing fouling.
