Most drilled oil and gas wells in Ghana employ the use of class G cement in its cementing operations. This class G cement is imported, scarcely available and relatively more expensive compared to other forms of …
— Barite colloid was prepared by simply mixing H 2 SO 4 solution and BaCl 2 solution and then nanosized particles (20 to 30 nm) formed (Fig. 1 a and Fig. S1 e). Afterwards, different Barite coatings were fabricated through dipping a series of Barite suspensions onto the substrates respectively to obtain various coatings (Fig. 1 a).CLSM …
— A major issue with the use of the weighting agents is that they settle out of the mud, causing density fluctuations that ultimately result in pipe sticking, lost circulation, and even well abandonment (Amani, 2018; Amighi and Moghadam, 2011; Paslay et al., 2007).This phenomenon is called barite sagging (Fig. 1), due to the predominant use of …

We explore to joint venture multi national companies to represent them in Malaysia, Indonesia and Thailand. To help develop business ventures
— In general, barite is used for raising the density of water-based mud and oil-based drilling fluids up to 22 ppg (2.64 sg). Barite is also used for weighting up kill fluids, and in the Barite lock plug formulation.
— Successful drilling operations are dependent on the properties of the drilling fluid used to drill wells. Barite is used as a weighting agent during the preparation of drilling fluid. Over the years, …
— Barite (barium sulfate, BaSO4) is vital to the oil and gas industry because it is a key constituent of the mud used to drill oil and gas wells. Elemental barium is an additive in optical glass, ceramic glazes, and other products. Within the United States, barite is produced mainly from mines in Nevada. Imports in 2011 (the latest year for which …
— Chelating agents with amino polycarboxylic acid structures can form easily soluble chelates with barium ions, thereby removing potential damage to oil and gas …
— In the oil and gas industry, cement segregation is a significant concern that can have disastrous consequences, such as the failure of cement. The change of hardened cement's properties is observed, resulting in a decrease in its strength and an increase in its permeability. Therefore, providing some solutions to prevent this is crucial. The objective …
— In this paper, we present the results of barite sag measurements before and after hot-rolled oil-based drilling fluids (OBDFs) using different approaches for characterization.
— Abstract. Barite is one of the most common weighting materials used in drilling fluid for deep oil and gas wells. Consequently, the main source of solids building the filter cake is the weighting material used in drilling fluids 'Barite particles'. Barite is insoluble in water and acids such as HCl, formic, citric, and acetic acids, as well as the barite has …
