This paper proposes β-cyclodextrin (β-CD) as a depressant for the recovery of barite from waste drilling fluid. The recovery process was investigated through inverse flotation experiments, and the mechanism was analyzed using zeta potential, contact angle analysis, and FTIR. The flotation experiments showed that under the SDS flotation …
Additives used in drilling-mud systems can influence mudcake erosional characteristics. Proper design of drilling and drill-in fluids is extremely important to control spurt and fluid invasion to minimize formation damage. A nonerodible mudcake on the borehole wall reduces drilling-fluid-induced formation damage.
the barite sold in the United States used as a weighting agent in fluids used in the drilling of oil and natural gas wells. The majority of Nevada crude barite was ground in Nevada and then sold to companies drilling in the Central and Western United States.

Drilling mud barite. The 2 most abundant solids in most drilling muds are barite (i.e., barium sulfate [BaSO 4]) and bentonite clay.Bentonite is used to increase the viscosity of the drilling mud and, in many modern WBMs, is replaced by a water-soluble organic polymer, such as carboxymethylcellulose ().Barite is used as a weighting agent …
Sponges were exposed to suspended bentonite and barite, the primary particulate compounds in drilling waste, as well as suspended natural sediment particles for a period of 33 days (on average 10 mg L −1 for 12 h day −1). The exposure period was followed by a pollution abatement period for a further 33 days.

Some of these metals are added intentionally to drilling muds as metal salts and organo-metallic compounds, if approved by local regulations. These metals are included in the added metals category. Most metals in drilling discharges are trace …
Barite (barium sulfate, BaSO4) contains 58.8 % barium and has a specific gravity of (4.2–4.5). The barite used in drilling fluid, which is normally impure, is of lower specific gravity as it contains other minerals such as quartz, chert, calcite, anhydrite, celestite, and various silicates. Also, it consists of other iron minerals, …
For a drilling fluid density of 2.0 g/cu cm(16.7 lb/gal), 33% to 35% of drilling fluid volume is barite. At this high loading level, barite has a major impact on the rest of the drilling operation. ... DeepOcean awarded a five-year contract extension in Mexico. Aug 20, 2024.

a remote sump or land treatment site. For drilling waste disposal that occurred before November 1, 2012, this guideline harmonizes ESRD requirements for drilling waste disposal areas with the 1996 Directive 50 whenever possible. For drilling waste disposal that occurred on or after November 1, 2012 this guideline harmonizes with Directive 50
High-density waste drilling fluid contains an abundance of recyclable weighting reagents, direct disposal can pollute the environment. In this paper, the primary mineral composition of a high-density waste drilling fluid from a well in the southwest oil and gas field was analyzed. This paper proposes β-cyclodextrin (β-CD) as a depressant …

A new polymer-coated barite weighting agent for oil-based drilling fluids has been developed to minimize the sag potential whilst maintaining low rheology. This new material uses ultra-fine barite particles, with 60% of the particles typically less than 2 microns. The ultra-fine barite particles are coated with a specially developed
The presence of Barite in drilling mud has created waste which needs to undergo costly crushing operations, and so it can sometimes be economically viable to recover this material from drilling waste.
