Partial Replacement of Saudi Class G cement with Red Mud for 15.8 ppg Cement Slurries

This study focuses on investigating the potential integration of red mud, a by-product from aluminum production, as a component in the oil well cementing process, with the aim to contribute to the oil and gas industry's sustainability efforts.A variety of experimental approaches were undertaken to develop cement slurries by blending Saudi Class G cement with red mud in a ratio of 90/10.The purpose of this specific blend was to determine the feasibility of using red mud as a sustainable, quality-maintaining alternative in cement formulations.The study included a detailed analysis, adjusting the content of viscosifying agents and fluid loss prevention additives to refine the properties of the slurry, seeking ideal cement properties.The objective was to engineer a cement slurry with a density of 15.8 ppg.Rigorous assessments scrutinized the slurry's rheological properties and the duration required to reach the thickening time.Preliminary results revealed that blends of only Class G cement with red mud fell short of meeting the industry benchmarks.Conversely, when retarders and viscosifiers were precisely incorporated into the mixture, enhanced performance of the slurry was achieved that complied with the exacting oil well cementing standards.These advancements are noteworthy as they indicate red mud's capacity to support environmentally sustainable cementing methods without compromising the essential attributes of performance.Consequently, the study advocates for red mood as a viable and responsible choice for inclusion within the repertoire of materials used by the oil and gas industry.
