... Abstract One of the main challenges of gas production well is scale built up which leads to flow restriction around perforated holes in front of the sand face. The scale formation usually starts at the tubing wall but with time accumulation, scale build up finally develops into full bore...

.... Regarding one thermogenic platform, a comprehensive review of potential leak paths on drilling history, seismic data, and casing pressure information indicated a shallow sand break due to inner-and-outer casing communication. Despite no gas accumulation in the riserless section, the well was abandoned...

... of particulate fluids depends on multiple factors including the magnitude of the injectivity contrast present in the reservoir, how much flow resistance may be achieved by accumulating particulate filter cakes in perforations and how quickly the accumulation can start. The onset of diversion requires perforation...

... in deposition of 10 g of salt which is a quite fast deposition rate if we consider 5000 BWPD flowing through a pipeline, due to such high rate of accumulation the pressure trends tend to sharply increase instead of gradual which limits the time for any preventive maintenance for wells or pipelines. Although...

... the top of Paleozoic sequence contain comparatively smaller quantities of hydrocarbons. Hydrocarbon accumulations in the DDb are primarily structural traps, however faults and stratigraphic pinchouts usually control outlines of individual pools. Majority of the hydrocarbon fields in Upper Carboniferous...

... for operation of the pipelines should be based on flow stability and water wetting the wall, and on acceptable pressure drop, but not by liquid or water holdup/accumulation. Dynamic flow behavior analysis in this paper shows flow stability corresponds to the gas flow rates for different pipeline sizes...

... from lower formation based on logging data. The paper put forward the theoretical calculation formula for liquid effusion of horizontal well bore and the prediction formula of liquid discharge time. By discharging the accumulated liquid from the well trajectory at the high permeability zone...

... hydrocarbon charge and trap formation, role of the faults in hydrocarbon migration and accumulation, uncertainties related to input parameters, and last but not least to support the risk matrix concept to increase the confidence in assigned risk values.

... Abstract Effective cuttings removal in deviated and horizontal wells is essential for improving drilling efficiency and preventing non-productive time (NPT) caused by hole-cleaning issues. While various numerical models have been developed to simulate cuttings accumulation in wellbores, only...

... on developing the fields. This paper is part of the basin scale study to address the distribution of CO 2 and its risk assessment. Modelling of the petroleum system including CO 2 contaminant was adopted to validate the fluid accumulations in the basin with observed results from fields. An Earth Model...

... shallow reservoirs 400 - 1000 m depth then it was injected to main zone reservoirs where the main accumulation of oil situated. This low salinity water reacted positively with the rock properties and in-situ fluids which was described as wettability alteration in the reservoir. It is related to initial...

... Abstract Many fields in South East Asia are suffering from sand production problems due to sensitive sandstone formation. Sand production increases with time and increasing water production. The production of sand induces loss of production, due to sand accumulation in the wellbore, and heavy...

... pipes required a conservative approach to hydraulics. Sensitivity analyses were performed on critical parameters. The pipeline network design was refined through a cycle of site visits to obtain pipeline corridors and GCPs land use permits. Diameters were optimized to lower liquid accumulation...
