Abstract: A logging tool is disposed in a wellbore during an acidizing operation. The logging tool may be an acoustic tool, a resistivity tool, or a neutron tool. Measurements are made using the logging tool on a region of a formation penetrated by the wellbore and being subjected to the acidizing operation. A formation property is inferred at one or more depths of investigation within the region using the measurements, and acidizing operation management decisions are made based on the determined inferred property. The inferred property may also be simulated. A minimized difference between the inferred formation property and the corresponding simulated formation property is determined, and acidizing operation management decisions are made based on the determined difference. The inferred property may be acoustic velocity, conductivity peak observation time, near-to-far detector count ratio, or porosity. An acidizing operation management decision may be to maintain, increase, or decrease an acid injection rate.

Abstract: An emulsion is mixed with fibers while the emulsion is moving through a surface tubing using a venturi. The fiber/emulsion mixture is injected into a pressurized tank and the pressurized fiber/emulsion mixture is injected from the pressurized tank into a desired location in a wellbore. Pumps and pressure boosters may be used to move the fluid. Alternatively, an emulsion and a fiber suspension is provided and a first downhole tubing disposed in a wellbore conveys the emulsion downhole while a second downhole tubing disposed in the wellbore and circumferentially enclosing all or part of the first downhole tubing conveys the fiber suspension downhole. The first downhole tubing has nozzles through which the emulsion passes into the second downhole tubing and the emulsion and the fiber suspension mix. The mixture exits the second downhole tubing through ports at a desired location in the wellbore.

Abstract: A chemical stimulation system and a resistivity tool are disposed in a wellbore. Chemical stimulation operations are performed in the wellbore using the chemical stimulation system. Resistivity measurements are made with the resistivity tool before, during, and/or after the chemical stimulation operations. The resistivity measurements may be used to determine the porosity of a formation penetrated by the wellbore. A wormhole distribution and/or penetration in the formation is determined based on the resistivity measurements. Decisions regarding stimulation operations are made based on the determined wormhole distribution and/or penetration. The resistivity tool may be modular and have various arrays allowing various depths of investigation. The depths of penetration of the wormholes into the formation may be determined using the measurements from the multiple depths of investigation. The volume of the formation that is dissolved by the chemical stimulation operations may also be estimated.

Abstract: A measurement tool having one or more measurement cells disposed in a fluid flow path is provided. Measurements are made in each of the measurement cells and a fluid type is identified based on the outcome of the measurements. A numerical value is associated with each measurement cell based on the identified fluid type, and a total fractional volume of the identified fluids is determined using the associated numerical values. There may be a relatively large number of measurement cells distributed so as to substantially cover the cross-sectional area of the flow path, relatively few measurement cells distributed randomly in fixed locations in the flow path, or a single measurement cell moveably located in the flow path. The measurement cells measure a property such as resistivity, capacitance, dielectric constant, or electrical impedance. The total fractional volumes of the identified fluids may be determined using a statistic.
