Because it is a continuous monitoring process with strict quality control from the raw materials, this process allows the selection of the desired particle size for the requested product. The alkalization of the raw materials for modification ensures a solubility greater than 97% and results in a high-quality product mix in acidic solutions. It provides a wide range of particles for the prevention and control of lost circulation, reinforces the mud through bridging, generating low permeability, and is compatible with water-based and oil-based drilling systems. This provides optimal conditions in drilling operations to reduce or eliminate partial and / or total circulation losses.It has a range of products with granulometries: fine, medium, coarse and extra coarse for the production zone of the oil industry, these presentations comply with the parameters required by PEMEX, "single operational guide to determine the technical specifications of ultra-low invasion plugs for well interventions, First Version, July 2021."

Embodiments relate to acquiring well, reservoir and production data, synthesizing training and test data, and then constructing, training, and utilizing machine-learning models to: (i) predict whether or not gas lift should be applied to facilitate the production of subsurface fluids from an oil well, (ii) predict an optimal range of gas lift values to be used in the production of fluids from the oil well, and (iii) predict an optimal liquid production rate for the oil well when the gas lift value is within the predicted optimal range. Unlike traditional approaches, the disclosed embodiments do not require the use of well interventions, which eliminates production losses, delays, and costs. The disclosed embodiments also avoid the delays, biases, and non-optimized values associated with existing trial-and-error-based approaches to gas lift injection optimization. Disclosed embodiments enable the efficient and reliable determination of the optimal range of gas lift values and the optimal liquid production rate.
