“…Filter cake is intentionally formed to prevent the reservoir formation and minimize the damage. − On the other hand, the filter cake must be efficiently cleaned after the drilling operation to enhance the productivity of the open-hole section and ensure good cementing quality for the cased sections. − In general, the filter cake layer is classified according to the source of the solids that form the layer. It is mainly either the drilling fluid solid additives (e.g., weighting material of the drilling fluid, such as barite, calcite, ilmenite, manganese tetroxide, and others) or the formation solids (cuttings) that accumulate during the drilling operations, if not removed. − From the removal perspectives, the filter cake is also be classified on the basis of the base of the drilling fluid. Chelating agent solutions, such as DTPA, EDTA, GLDA, and HEDTA, were very active in dissolving metal-containing materials that form the filter cake layer.…”

Chelating agents show very effective performance in different applications in the upstream oil and gas industry. This study presents a critical review of the application of chelating agents in acidizing, scale removal, filter cake removal, wettability alteration, enhanced oil recovery (EOR), and hydraulic fracturing treatments. The advantages and disadvantages of using several types of chelating agents for improving the well/reservoir productivity and enhancing the oil recovery from sandstone and carbonate reservoirs are discussed. Also, detailed comparisons between different chelating agents and their applications in many oil and gas areas are presented. Moreover, the combination of chelating agents with different chemicals to achieve better performance is addressed. Hydroxy amino carboxylic acids [such as ethylenediaminetetraacetic acid (EDTA) and glutamic acid diacetic acid (GLDA)] have replaced conventional acids, such as hydrochloric acid (HCl), hydrofluoric acid (HF), and organic acids, at high temperature and salinity conditions to stimulate carbonate and sandstone reservoirs without any side effects on the formation integrity. Furthermore, diethylenetriaminepentaacetic acid (DTPA) and GLDA are effective in removing different types of scales, such as carbonate, sulfate, and sulfides, without releasing hydrogen sulfide (H 2 S) and using corrosion inhibitors. Also, DTPA, EDTA, and GLDA are very active in dissolving filter cake layers formed by different drilling fluids. Aminopolycarboxylic groups can be injected into sandstone and carbonate reservoirs to adjust the wettability conditions and enhance oil recovery. Chelating agents, such as GLDA, EDTA, and DTPA, optimize the fracture conductivity and, meanwhile, minimize the number of additives in hydraulic fracturing, which significantly cut the cost of the operation. Overall, chelating agents are economically attractive chemicals for various upstream operations since produced, and seawater can be used without further treatment.

“…The reaction of selected organic acids and chelating agents with Mn 3 O 4 particles as a function of time and temperature was studied [35]. Mn 3 O 4 is a strong oxidizing agent and can be used as a catalyst because of its active phase, a nonstoichiometric Mn 3 O 4 composed of an octahedral Mn 2 O 3 phase and a tetrahedral MnO phase, which will result in complex interactions with most cleaning fluids.…”

“…In addition, the weighing material account for almost 70–90% of the filter cake mineralogy 19 . Furthermore, the weighting material might damage the formation during the formation and removal process of the filter cake 36 , 37 , hence it is critical to add filtration agents to minimize the filtration to the formation. Many filtering agents have been developed and employed in the oil and gas sector throughout the years and despite the success stories for them.…”

A required feature of any drilling formulation is to mitigate the formation damage by having an excellent filtration and filter cake properties. The key factor for preventing and limiting formation damage is to improve the sealing qualities of the planned drilling fluid. In this study, a new novel filtration agent called “perlite” was introduced for improving the manganese tetroxide mud cake ability for better sealing features. The perlite particles were loaded to formulation containing the manganese tetroxide as weighting agent. The water-based drilling mud was designed at high densities (14.25 and 17.2 ppg). Perlite was added in varied concentrations to reach the optimum performance. The filtration test conducted at reservoir temperature of 250 °F and a differential pressure of 300 psi to form the filter cake. The tests were performed using sandstone cores with two different permeability categories (low and high permeabilities) as the filtration media. This gave the full picture of perlite performance as implemented for different formation properties and considering the drilling fluid properties. The formed filter cake structure and chemical composition was evaluated using scanning electron energy-dispersive X-ray (SEM–EDS). The presented results illustrated how the perlite was compatible to be added to the manganese tetroxide weighting agents in the same formulation. In addition, it has the capacity to improve the filter cake's sealing qualities, lowering the filtration volume by 41% and the filter cake internal and external layers permeability by 58% and 25%, respectively. Moreover, the EDS analysis showed that the perlite particles are concentrated generally in the internal layer of the filter cake.
