Invert emulsion drilling fluids that have extended emulsion stability and reduced sag potential are described herein. The drilling fluids comprise an invert emulsion, a weighting agent, and a plurality of colloidal particles. The invert emulsion comprises an oleaginous fluid continuous phase, an aqueous fluid internal phase, and a surfactant.

Barite is barium sulfate (BaSO4), the most common mineral of the barium element. Barite is the heaviest of non-metallic minerals. The high density of barite (4.45 gr / cm3), being less abrasive (Moh 3-3,5), it has been designed to maintain its chemical stability under high temperature and pressure, its low cost in water and acids, the reason for its special use of magnetic and its …

Drilling high-pressure high-temperature (HPHT) wells requires a special fluid formulation that is capable of controlling the high pressure and is stable under the high downhole temperature. Barite-weighted fluids are common for such purpose because of the good properties of barite, its low cost, and its availability. However, solids settlement is a major problem …

A Barite plug is basically a slurry of barite that is pumped down the drill pipe and placed at the bottom of the wellbore. A successful Barite plug should accomplish two things: Initially, the weight of the barite slurry should kill the well. After a period of time, the settled barite plug should mechanically block any flow up the wellbore.

The barite sag tendency was also evaluated using the viscometer sag-shoe test (VSST) method (Figure 2) described in the literature.5 The test results were compared against a 4.2-SG barite 18-lb/gal benchmark fluid. The replacement method followed a similar procedure except instead of creating a blend of new weighting material,

The Viscometer Sag Shoe Test (VSST) is a well site and laboratory test that measures the weight material sag tendency of field and lab-prepared drilling fluids under dynamic conditions. The VSST provides an intrinsic fluid property without regard to the conditions under which the fluid has been or will be used.

Barite sag is one of the challenges faced when drilling ERD wells. It can lead to many problems such as: mud weight fluctuations, downhole losses, well control situations and stuck pipe. Barite sag can be accelerated when the mud is static or at low shear rates for example when slow circulation, running casing or even wireline logging.
