Revolutionising Cement Evaluation in Mexico's Exploration Wells: Unleashing the Power of Extreme Ultrasonic Technology

The evaluation of well cementing has historically been a point of great importance during well construction. The evaluation of cementing has evolved over the last decades into an increasingly demanding technique, driven by both stricter regulatory requirements and more complex well construction designs. Over the years, regulatory and normative requirements have evolved to ensure safety and environmental protection up to the surface. Isolation must be demonstrated after well construction, as well as at the end of the well's life before it is plugged and abandoned. Cement bond log (CBL) and variable density log (VDL) were introduced in the 1960's. These tools provide qualitative insights into the cement's bond with the formation (VDL). This is achieved through the propagation of acoustic energy, leveraging the variance in acoustic impedance between the pipe and the material behind it—whether it be solid, liquid, or gas.
