Abstract

See full text

The invention provides a method of manufacturing a solid phase barite containing material for use in a wellbore. The method includes the steps of providing the barite containing material having relatively small particles with a particle size distribution of at least 50 vol % particles having a diameter in the range of 1 μm to 10 μm and at least 90 vol % particles having a diameter in the range of 4 μm to 20 μm; and contacting the barite containing material with a liquid in order to form relatively large particles having a particle size distribution with at least 90 vol % of the particles having a diameter of at least 30 μm. There is also described a method of treating a wellbore with a fluid including the barite containing material.
