Experimental investigation of flame propagation mitigation using woven wire and perforated metal meshes in circular pipe

Explosions due to gas leaks from accidents and human errors are major concerns faced in natural gas and related industries. Understanding its formation and dissociation mechanisms at field conditions is keys to its successful prevention and management. In the present study, two different meshes with different sized flow channels were proposed to prevent and control methane combustion in a circular gas pipeline. The...

Experimental investigation of impact of low salinity surfactant flooding for enhance oil recovery: Niger Delta field application

Oil reserves in the Niger Delta have been gradually decreasing due to the increased production. New large field discoveries are scarce, thus there is need to improve on the production from existing reserves. Low salinity surfactant flooding (LSSF) is a potential enhanced oil recovery process to increase oil production in the Niger Delta oil fields. In this study, sodium dodecyl sulphate and ethanol were used as...

Pipe irregularities mapping using tomographic instrumentation system

Formation of irregularities on the inner surface of pipes is a common phenomenon that leads to corrosion and affects the functionality in the processing industries. Ultrasonic is known as one of the non-destructive means to address the formation of irregularities inside pipes. In this study, an ultrasonic measurement system is developed to detect the presence of internal irregularities in a pipe. An ultrasonic sensor...

Water invasion evaluation of Kela 2 Gas Field

Kela 2 Gas Field is a large blocked structural reservoir with bottom water in Kuqa Depression, Tarim Basin. Reservoir is mainly deposited as delta front underwater distributary channel in Bashijiqiuke Formation during Early Cretaceous. Reservoir thickness is over 460 m and average net-to-gross ratio is 78%. There developed faults in the reservoir which has strong anisotropy, porosity of the reservoir is 10 to 18% while...
