Mill out testing during the qualification phase is key to the plug performance in real bottomhole conditions. Multiple plugs are used in a single well that ideally will be milled out sequentially. Thus performing a mill test with only one plug may result in an optimistic view of plug milling.

Barytes bearing veins are found mostly in the area geologically referred to as Middle Benue Trough. Nigeria has an estimated reserve of over two million {2,000,000} metric tons of barite ore scattered in different parts of the country to include Benue, Nassarrawa, Plateau and Cross River states.

Nigeria's Minister of Mines and Steel Development, Mr Olamilekan Adegbite, announced that Nigeria will ban the importation of barite to help the country save foreign exchange for other purposes. This comes as the Central Bank recently banned the importation of maize for the same reason as Nigeria aims to save foreign exchange in an era of falling oil …

BARTEX, manufactured at the US plant, is produced from high grade barites (barium sulfate) utilizing a milling process. The plant dedicates one of eight milling lines to the production of BARTEX, which accounted for approximately 10% of our 2004 and 2003 net sales. Barium Sulfate's high density is one of the primary reasons it is used in coatings.

Barite (barytes) is naturally-occurring barium sulphate (BaSO 4) and is the predominant barium mineral used for industrial purposes.
