This paper discusses problems associated with waterbased drilling fluids used for drilling formations with abnormally high pressure. The available solutions are suitable for a narrow range of applications, especially when weighted muds should be used. This paper reviews the experience of searching and developing a new type of drilling mud based on saturated brines. With the referenced papers ...

Abstract. The quality of mineral additives used in a drilling field (mud) can dramatically affect the fluid's properties and the overall cost of drilling an oil or gas well. The principally used minerals are bentonite, barite, barite/hematite blends, and hematite alone. The high specific gravity minerals, barite and hematite, are used to ...

Barite Mill. Bentonite is a montmorillonitebased clay mineral, which can be divided into sodiumbased bentonite and calciumbased bentonite. It can be used as binder, suspending agent, filler, catalyst, etc. It is widely used in petroleum extraction, directional crossing, steel casting, metallurgical pellets, chemical coatings field.

Weighting agents such as barite, micromax, ilmenite, and hematite are commonly added to drilling fluids to produce highdensity 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. In this study, the variation in the drilling fluid's rheological and filtration properties ...

For most of the typical accessories of bentonites reliable densities are known. However, for some minerals—as zeolites, illitemuscovite, chlorites—only density ranges were found which results from (1) different hydration states (in the case of zeolites) and (2) isomorphic substitution (mainly Fecontent).
