GraviGuard

Their primary objective is to control formation pressure by creating enough hydrostatic pressure in the hole that ensures borehole stability. Also, they reduce the amount of fluid loss in the formation by making a mud cake on the borehole walls. Drilling fluids evolved from a simple mixture of water and clay to complex formulations containing organic, inorganic, and polymeric compounds to meet operational demands and challenges. Commonly used weighting materials are calcium carbonate, barium sulfate or barite, hematite, manganese tetroxide, and ilmenite. The hydrostatic pressure exerted during the drilling operation is controlled by adding a weighting agent to the drilling fluids. Various weighting materials such as barite, calcium carbonate, hematite, and ilmenite are used to increase the density of drilling fluids. Some weighting additives can cause serious drilling problems, including particle settling, formation damage, erosion, and insoluble filters. Barite is a mainly used weighting agent in drilling fluids because of its high specific gravity and inertness toward many chemical additives mixed in drilling fluids.

However, barite applications have some limitations, such as dissolution in the sodium and potassium formate-based drilling fluids, high PV, low acid solubility, and significant sagging. Other additives, such as ilmenite and hematite, are also used as weighing materials in drilling fluids. Several benefits are associated with both materials, such as the minimum impact on rheology, improvement in the rate of penetration, less dilution, and better solid tolerance. However, the potential issues with them are the abrasiveness and magnetic characteristics of iron oxide. Weighting agents such as barite, ilmenite, and hematite are added to drilling fluids to produce high-density fluids that could be used to drill deep oil and gas wells. Increasing the drilling fluid density leads to highly conspicuous fluctuation in the drilling fluid characteristics. At Centum, scientists and chemists are non-stop evaluating, testing, and analyzing various commercially available weighting additives and their performance. Our chemists and scientists custom engineer weighting additives to meet a specific drilling project.

GraviGuard

GraviGuard is the result of Centum’s never-ending innovation. Centum scientists have formulated and engineered GraviGuard seeing the market need for an ultra-performing weighting additive. After years of rigorous testing and analysis, we have designed to address the needs of drilling operators and engineers. It is a sustainable, readily, and ultimately biodegradable additive blend that offers maximum weighting performance during onshore and offshore drilling operations. Centum’s GraviGuard is equally suitable for oil, synthetic, and water-based drilling fluids. Our weighting additive blend is designed to address ESG, and sustainability regulations governments implement worldwide. It does not contaminate seawater, land, and reservoirs and is non-toxic to fish, animals, and other living species. At Centum, we custom formulate weighting additives to meet specific drilling operation needs.
