    Hydraulic Fracturing (Fracturing Fluids and Proppants) - RILS

    This is a virtual course under Remote Instructor Led Series (RILS), delivered in two half-days in daily 4-hour sessions. The course describes fundamentals of Fracturing Fluids (Rheology, Types of Fluids and Leak-off) and Proppants used in Hydraulic Fractuirng.

    Being a practical application of these fundamentals, the course starts describing the different types of gels used in Hydraulic Fracturing, explaining basic concepts of Rheology that apply to Fracturing Fluids and the role of leak-off control; the application of different types of Propants is also discussed as well as the impact in pos-fracturing production. Numerous exercises, pedagogically selected, are executed and can be used in the future as guidelines to solve real challenges.

    Softcopies of the slides will be sent to the Attendants. The Attendants will have to print hardcopies to be used during the lecture; formulas and exercises will be provided electronically in the form of a toolbox - a Practical Companion to Hydraulic Fracturing (Fracturing Fluids and Proppants).

    A pre-course quiz will be electronically sent to the Attendants to enable the Instructor to adjust the lecture to optimum effciency, and a last-day quiz will measure improvement.

    At the end of the course, Attendants will become conversant in the applications of Hydraulic Fracturing (Fracturing Fluids and Proppants).
