... inhibitors are also characterized to determine their functional groups in aqueous state. The tendency of scale inhibitors to impede silicate polymerization process is also determined through the remaining concentration of monomeric silica in water after 72 hours. FTIR revealed that all scale inhibitors...

...) and desorption of absorbed hydrocarbon from rock surface. As surfactant has a foam tendency, it becomes an operation challenge to maintain the quality of crude and produced water in the production stream. This paper aimed to describe the operation troubleshooting experience involved in lab analysis and field...

... bridging package based on the pore size distribution was also introduced, using calcium carbonate and resilient graphite particles. The combination of effective bridging and sealing polymer helped in sustaining high overbalance to avoid differential sticking tendency, designed in laboratory conditions...

... such as Dichloromethane (DCM). The colloidal instability index (CII) is a screening criterion, suggested by Yen et al (2001) to identify the precipitation tendency of asphaltene in crude. The colloidal instability index considers that asphaltene exists as a colloidal substance which is dispersed among the crude oil...

... result in emulsion formation and/or solids deposition hence the corrosion inhibitor must meet the key properties such as high performance, high temperature stability, low emulsion and foaming tendency. Performance: The selected corrosion inhibitors must have very high corrosion protection under...

..., the tendency is to consider churn flow as a flow pattern itself rather than an entrance effect related to slug flo w 11 , 12 , 15 . Even though, it is still difficult to consider it as a unanimous opinion. In annuli, small-scale experiments confirmed the occurrence of the same flow configurations...

... for these fracture treatments are presented where they differ from conventional fracturing. High permeability formations often have a tendency to produce sand. The effect of fracturing on the sanding tendency and the potential of using fractures as a sand control method are discussed. wellbore hydraulic...
