A real-time virtual monitoring system of the skin factor for matrix acidizing treatments

It is known that oil well productivity can be correlated with the quantification of the damage to the formation (skin factor) and that oil well stimulation through acidizing treatment may be used to improve the permeability of the well pore and restore oil productivity. Current monitoring systems of the skin factor have focused on acid treatments with a single-phase, in which the determination of skin factor is carried out via simplified models in a closed-form, avoiding the need for a real-time platform. However, the combination of several injected fluids is a common procedure in matrix acidizing treatments, giving rise to the formation of foams and two-phase flow. In this case, the real-time estimation of the skin factor requires robust models whose numerical solution should be synchronized with the dynamics of the matrix acidizing treatment in a real-time platform.This paper presents a real-time virtual monitoring system in the wellbore of an oil field to monitor the evolving skin factor during gelling foam acidizing treatments, in which the estimation of the skin factor is conditioned by real-time constraints. The system performance is evaluated using field data available from the stimulation treatments in oil wells located in southeast Mexico. The output results indicate that the real-time virtual monitoring system can successfully predict the evolution of the skin factor. This information is useful for the control and optimization of matrix acidizing treatment.

Active control of hydraulic oil contamination to extend the service life of aviation hydraulic system

The hydraulic system is the control center of aircraft, the performance of which is critically dependent on the purity of the oil that flows through it. Contamination of hydraulic system oil has been known to be the primary cause of catastrophic failure and accidents. A review of literature in the area of hydraulic oil contamination reveals three facts: (i) there is a dearth of effective methods to prevent intrusion of external contaminants into the hydraulic oil, (ii) there are no effective purification methods for liquid and gaseous contaminants of oil, and (iii) there is an absence of real-time monitoring for major contaminants. This work systematically reviews the hazards, sources, and removal methods of major contaminants, especially of gaseous contaminants. An active method to control oil contamination is proposed instead of the existing passive maintenance techniques that are ridden with problems. In a case study of aviation hydraulic system, our active control system comprises (i) a closed hydraulic circuit and a closed oil tank to prevent the intrusion of external contaminants, (ii) a vacuum centrifuge to efficiently remove contaminants without creating consumption costs, and (iii) monitoring devices installed to actively monitor the contaminant content in oil during operation. The results from the purification experiments and three-dimensional modeling indicate that the active control of hydraulic oil contamination can effectively remove 98.4% solid contaminants and reduce the water content below 50 ppm, and in particular reduce the gas content below 2%. It is obvious that this method can improve the continuous operation capability of aviation hydraulic systems and extend the intermaintenance period of aircrafts by reducing the contaminant content in oil.
