Grade of samples with specific gravity of 2.4gr / cm3 Barium sulfate powder produced by Petro Kavir Mahan, based on the results of the presented analyzes, reaches more than 60% of barium oxide (equivalent to 93% of barium sulfate or barite mineral), which of course this grade Flexible according to orders. The table below shows the results of the analyzes. In addition to the presented results, the ability to provide higher density drilling barite powder is also provided in the complex. So that the densities of powder produced by Petrokvir Mahan in recent years show an average of 4.24 gr / cm3. It should be noted that domestic companies purchasing barite powder as well as reputable laboratories have the highest quality of barite powder produced by Petrocoyer Mahan in terms of physical properties such as density, viscosity, sizing and also in terms of chemical properties such as dissolution of alkaline earth metals. A range of standards have been introduced in the form of API for the production of drilling mud for oil wells, which can be easily achieved by analyzing the samples of Petro Kavir Mahan that are ready to be sent.
