... size and structure. The finite element method was utilized to analyze the stress and sealing condition of packer during the packer setting and perforation. Considering the fluid injection process and temperature change during acid fracturing treatment, the stress distribution of the pipeline under...

... Abstract A new approach to acidizing gas wells where an inert dry chemical hermetically was sealed inside a metal carrier and deployed downhole via slick-e-line. Once in place downhole, an exothermic chemical reaction was initiated which produces hot acid vapour. This method permits target acid...

... Abstract Acid fracturing enhances hydrocarbon production in tight carbonate reservoirs by creating fracture conductivity through non-uniform acid-rock reactions along fracture walls. Multi-stage alternating injection in acid fracturing has been demonstrated to effectively enhance non-uniform...

... Abstract Organic acids, together with other polar molecules, constitute the oil-wetting components in crude oil. A commonly adopted understanding is that the adsorption of organic acids leads to the further adsorption of organic materials on the hydrophobic tail groups of the adsorbed organic...

... with a total of 4,000 bbl of single-phase retarded inorganic acid system (SPRIAS), which enables carbonate stimulation with better worm holing performance than emulsified acid while eliminating its drawbacks, such as high CT friction pressure and potential emulsion issues. In comparison with emulsified acid...

... Abstract Carbonate reservoirs have different approaches to acid stimulation techniques. In order to achieve the most effective results, it varies by utilizing different diverters, acid systems, and pumping types. Even after improving the coiled tubing placement and numerical model predictions...

... Abstract Acid fracturing in challenging gas wells imposes multiple areas for improvement. The objective is to implement effective acid fracturing treatment with combination of CO 2 foam and the use of dissolvable plugs to maximize diversion across the net pay and to improve overall operations...

... Abstract Acid matrix stimulation in Nimr fields located in the South of the Sultanate of Oman has historically been utilized with caution for production enhancement. This is due to the prevalence of clastic rock as the main rock type coupled with the lack of precise minerology data from all...

...Diverter classification Acid placement during matrix stimulation or acid fracturing is a critical step to achieve efferent stimulation treatment. Usually the fluid is prone to flowing into the least resistance path which is the high permeable interval or fractured zones. Those parts...

... Abstract Matrix acidizing technique is used to enhance the production of hydrocarbons from a reservoir, especially in low permeable reservoirs and in the case of formation damage. In carbonate reservoirs, acid stimulation jobs are challenging due to the acid's strong reactivity...
