Evaluation Of The Formation Of Asphaltene Mud Resulting From The Action Of Oil Well Acidity Using Microwaves

Working acid is one of the traditional and conventional methods of stimulating oil and gas wells. In this process, acid is injected into the formation around the well and by dissolving the desired compounds (sediments and reservoir rock), it causes damage to the formation and increases porosity and permeability. It is in the area around the well. The inhomogeneity and interaction of the injected stimulating fluids and the reservoir fluid can lead to the creation of new structural damage caused by organic sediments, which subsequently leads to a reduction in the efficiency of the stimulating operation or its complete failure.Acidizing is one of the traditional methods of stimulating oil and gas wells. In this process, acid is injected into the formation around the well and by dissolving the relevant compounds (such as sediment and reservoir rock), it damages the formation and increases the porosity and permeability around the well. It is possible that the heterogeneity and interaction of the injected stimulation fluids and the reservoir fluid may lead to damage to the new formation caused by organic sediment, which subsequently reduces the efficiency of the stimulation operation or causes its complete failure. The contact of various acids with asphalt oil has the possibility of destabilizing asphalt particles, which will happen if conditions are created for the deposition of asphalt sludge inside the formation. The presence of microwaves will have a positive effect in reducing this asphalt sludge, which is discussed in this article.Drilling mud is used to drill oil and gas wells, but during the use of drilling mud, the connection between the formation and the well column is interrupted during drilling, in such a way that the solid particles in the drilling mud penetrate into the pores of the formation, cutting off or reducing the connection. They are looking for the column well formation. After the completion of the drilling rig and well drilling, the operation engineering department of the oil and gas production companies are responsible for the production of the drilled wells. In order to establish the connection between the formation and the well column and the oil or gas flow, the drilling mud particles must be removed from the wall. The formation was destroyed, for which the acid method is used.
