- Abstract
Petroleum coke is a by-product from the coking process of high molecular weight hydrocarbons, its accumulation in Venezuela has been due to the increasing exploitation of heavy and extra-heavy crudes from the Orinoco Oil Belt, which is why it is urgent to propose other uses for it. The purpose of this research was to demonstrate the influence of petroleum coke on the rheological and mechanical properties (compressive strength and density) of cement slurries for oil wells; For this, the laboratory tests established in American Petroleum Institute (API) standards 10 A and 10 B were implemented: rheology, thickening time, free fluid, filtering and resistance to compression required to determine the effect of different concentrations of the material on the properties of the grouts. Similarly, three (3) low-density systems were formulated to investigate whether coke works efficiently as an extender additive since it has a specific gravity lower than that of cement. Through the statistical analysis of the results obtained, it was determined that coke works as an agent capable of producing exponential increases in rheological properties and resistance to compression. Also, it was verified that the solid allows reducing the density of the systems having as an advantage that it improves the compressive stress. The incorporation of the material for the aforementioned purposes in the cementing of wells would mean a solution to the growing accumulations of it and would contribute to the economy of these operations as well as representing an innovation in research.
