US 9,562,427 net oil and gas well test system by Henry, M, Casimiro, R

“…A net oil and gas well test system for a set of oil and gas wells includes at least two net oil and gas measurement systems and a plurality of valves that are in fluid communication with the individual wells in the set and independently configurable between a first state, in which the valve routes flow to a first net oil and gas measurement system, and a second state, in which the valve routes flow to a second net oil and gas measurement system. …”

Mathematical modelling of transient flow and heat transfer in a producing gas well by Mbaya, Jibrin Helma

“…This thesis focuses on the mathematical modeling of transient flow in a producing gas well. A producing gas well is a well that has enough pressure to push the gas from the reservoir to the wellhead. …”

Experiment and Application of Wax Deposition in Dabei Deep Condensate Gas Wells with High Pressure by Lihu Cao, Jinsheng Sun, Jianyi Liu, Jiquan Liu

“…Since the initial development, the wax deposition and plugging in the wellbore and gathering pipeline have been the most bothering issues, resulting in the reduction or even shutdown of condensate gas well production. Therefore, the wax appearance temperature of Dabei condensate oil was studied using the capillary viscometer, differential scanning calorimetry (DSC), and polarizing microscope observation. …”
