Sand production and blockage are common during the drilling and production of horizontal oil and gas wells as a result of formation breakdown. The use of high-pressure rotating jets and annular helical flow is an effective way to enhance horizontal wellbore cleanout. In this paper, we propose the idea of using supercritical CO2 (SC-CO2) as washing fluid in water-sensitive formation. SC-CO2 is m...

[1] Sea surface brightness anomalies caused by a municipal wastewater discharge are detected from space in areas much larger than their submerged turbulence source. The mechanism involves a complex interaction between currents, topography, tides, vertical and horizontal mixing, internal waves and stratified turbulence. Citation: Keeler, R. N., V. G.

The technology of submerged carbon powder injection with CO2 and O2 mixed gas (SCPI-COMG) is a new type technology. It can increase the molten bath content improve steel quality by injecting directly into gas. To optimize process parameters this novel technology, mechanism effect SCPI-COMG on EAF steelmaking were investigated in study. Based an induction furnace experiment, effects carburizatio...

grade control structures are hydraulic structures used to stabilize a river bed. scour downstream of this structure is the main cause of its failure. studies have developed numerous empirical relations for scour depth prediction that designers must choose between to decide the most effective equation for a specific application. this study tested the condition of submerged jets over beds of sedi...
