Technical Paper: Alternative Drilling Fluid Weighting

Another effect that has not been addressed sufficiently is the magnetic characteristic of these iron oxidecontaining minerals which has the potential to affect the operation of direction drilling and some other downhole tools. There have been many studies on the use of ilmenite and hematite as weight agents for drilling

Comparative Analysis of Barite and Hematite Used in Water

Mud additives contribute to the specific functions and properties to the drilling fluid, especially in case of rheological properties, which in turn attains multiple roles in the wellbore. The project work emphasizes only on three of the many available fluid additives – bentonite, barite and hematite whose

Hematite API Grade Manufacturers and Suppliers Hematite

Hematite API Grade. Description Weighting material is ground Hematite and meets API Specifiion 13A Section 8 for drilling fluid Hematite. It is used to increase the density of drilling fluids to control formation pressures.


The Hematite ore used as a weighting agent in drilling fluids has a micalike crystal structure ground to a particle size suitable for use in drilling fluids. Hematite is used to obtain mud weights in excess of 20.0 ppg in water based drilling fluids, 19.0 ppg in oil based drilling fluids, or any time that exceptional control is

Oil Muds And Its Troubleshooting CONTROL DRILLING SOLIDS

Nov 15, 2018 · An oil base fluid can be defined as a drilling fluid which has oil as its continuous or external phase and the water, if present, is the dispersed or internal phase. The solids in an oil base fluid are oil wet, all additives are oil dispersible and the filtrate of the mud is oil. The Continue reading "Oil Muds And Its Troubleshooting"

MySpread Forum Hematite in mud

Hematite is a good weighting agent when heavy muds are required. There is a limit to the weight that can be obtained with barite, and using barite to the 'max' leaves you with a very viscous mud system. Disadvantage of hematite is its hardness, so you will encounter higher wear on DP and casing, coupled with higher torque.

Hematite (Federal) Weight Density

Hematite is applicable in all types of drilling fluids, including freshwater, seawater and oilbase muds. It can be used to increase the density of all drilling and completion fluids to 25 lb/gal (3.0 SG). Hematite is most frequently used in highdensity, oilbase muds.

US594419 Method for separation of solids from drilling

A method is disclosed for treating drilling mud discharged from a well wherein the mud contains drill cuttings and paramagnetic materials such as hematite. The drilling mud is first passed through a highgradient magnetic separator to separate the paramagnetic materials from the drilling mud. The drilling mud is then passed through a centrifuge separator to remove the drill cuttings from the

Drilling fluid AAPG Wiki

The large number of functions performed by the drilling fluid require that some minimum properties of the fluids be maintained. The measurement of these properties gives the mud engineer a "status report" of the fluid and how it is reacting with the formation and the subsurface environment.
