... Abstract During oil production, when crude oil flows into a wellbore, pressure and temperature are reduced. The micelle structure of the crude oil is destabilized, allowing paraffin (wax) and/or asphaltene molecules to precipitate into the oil, increasing oil viscosity and allowing deposition...

... Abstract Organic precipitation during the production of hydrocarbons has proven to be a production assurance problem experienced in the majority of oil and gas fields throughout the world. Paraffin and asphaltene deposition occurs in several areas of the production system including...

... Abstract Maturation of hydrocarbon reserves often occurs conjointly with an increase in flow assurance challenges. Deposition of paraffin and/or asphaltene is at the forefront of these challenges. Well maturity, declining reservoir pressure, coupled with hydrocarbon deposition, negatively...

... and comprises three main sands, informally termed UP5a-c, deposited in a close-to base of slope, deep sea environmental setting. The post well subsurface evaluation in support of a pre-development project initially focused on the sedimentological analysis of the slabbed core. Quantitative data extracted from...

... to mitigate the production decline of the TSP (Teak, Samaan & Poui) asset located off the south-east coast of Trinidad. TSP is a mature oil field which has been producing for almost 40 years. The main constraints for flow assurance are sand production, scale and paraffin deposition, high IGLR, skin damage...

... Abstract The precipitation and deposition of paraffin wax during production, transportation and storage of crude oil are common problems encountered by the majority of oil producers around the world. During the last decade, the Barrackpore oilfield in Trinidad has reported wax deposition...

... Abstract Formation damage due to asphaltene deposition in oil reservoir is an issue for many countries that can have strong effect on oil production during heavy oil recovery, miscible flooding, and even primary recovery. Many tests were performed by researchers to determine the amount...

.... Cold finger experiments yielded excellent inhibition and confirmed the poor performance of the incumbent product. Field application yielded impressive results with a clear step change in performance. Field measurements showed that deposition was unlikely to be occurring in the flow line. Pour point...

... Abstract The Precipitation and deposition of crude oil polar fractions such as asphaltenes in petroleum reservoirs reduces considerably the rock permeability and the oil recovery. Therefore, it is of great importance to determine "how" and "how much" the asphaltenes precipitate as a function...
