Barite usually serves as a weighting agent in drilling muds for HDD and drilling fluids in oil and gas exploration. Product density avoids high-pressure blowouts (non-magnetic). Product with a specific gravity of 4.10+ is milled to 200 mesh particle size. Currently, we are delivering products in the Midland / Odessa and Pecos, Texas area.

Ilmenite (FeTiO3), with a mean particle size of 30 - 45 µm, was first introduced into the oil industry as weighting material in 1976. However, its use was limited mainly ... API standard barite is, by far, the most commonly used weighting agent in drilling fluids. However, it is not …

This study applied three kinds of ultra-fine powder (particle size≤4μm), which are new weighting materials, to replace the common API barite (particle size10~70μm). The different kinds of high-density oil-based drilling fluids, which weighted with micronized barite, micronized ilmenite, manganese tetraoxide and API barite, were prepared and ...

The size of the particles is called the grain size,and also could be referred to as the particle size. The particle size represents is that the particle diameter. ... API 13A barite powder for ...

In order to evaluate the effect of the barite particle size on carbothermic process, coarse-sized (−140, +230 mesh) middle-sized (−230, +400 mesh) and fine-sized (−400 mesh) were used in stoichiometric mixes of barite and coke (i.e., BaSO 4 + 4C). Also, 5% sodium carbonate and ferric nitrate were doped on coke as catalyst, based on dry weight of coke.

The API has designated size ranges for particulate material in drilling muds. Sand is defined as particles larger than 74 microns (200 mesh). Particles in the 2 to 74 micron range are called silt. API barite and API hematite have size specifications set by API Spec. 13A (see Table 4). Table 4 Familiar Size Comparisons. Particles. Microns

- has important properties:Toxicity, density, particle size and shape, hardness and density, corrosivity and abrasion with higher densities, increases the weight volume requirements in the mud - Galena is the heaviest but is toxic - Barite is harder than Hematite - Ilmenite is harder than Barite - API barite has a size range of 2-100 microns

The chart plots particle diameter in microns vs. volume % of both the 4.1 and 4.2 SG barite. It is readily apparent that both materials are of near-equal particle size distribution. The net effect on the volume requirement of 4.1 SG barite when raising fluid density of a 1200 kg/m 3 …

API Barite is a high purity barite (Barium Sulphate) in powder form. It is an inert material and fully conforms to either API standard 13A i.e., specific gravity of 4.10 minimum, 3% residue on a 200- mesh screen maximum, 5% residue on a 325-mesh screen minimum etc.

The American Petroleum Institute outlines several test procedures that help assure the quality of this important ingredient. Among these is the wet screen procedure for particle size analysis. The OFITE Particle Size Kit contains all of the equipment necessary to perform particle size analysis as specified in API Specification 13A.

with conventional API grade barite, the particle size is very close to that of the drilled solids which invariably become incorporated into the drilling-fluid system. In these instances, reducing the screen size to 250-mesh or finer removes barite as well as unwanted low-gravity drilled solids, resulting in …

Particle-size distributions are used to evaluate bridging materials for drill-in and completion fluids. Barite and hematite samples are examined to ensure performance without excessive wear on equipment and as an API/ISO quality specification. See: abrasion test, bridging material, ...

barite is expected to have a specific gravity of at least 4.20 g/cm3 to meet API specifications. Contaminants in barite, such as cement, siderite, pyrrhotite, gypsum and anhydrite, can cause problems in certain mud systems and should be evaluated in any quality assurance program for …

diameter. Presently, it is not possible to separate desirable barite particles from undesirable drilled-solid particles that settle at the same rate. The recognized rule of thumb is: A barite particle (SG 4.25) will settle at the same rate as a drilled-solids particle (SG 2.65) having 1½ times the barite particle's diameter.

drilling-grade barite were already in place both for density (>4.25 g/cm3) and particle size, which stipulated that 98.75% should pass through a 300-mesh (45-micron equivalent) shaker screen. Since then, several refinements to the specification have been made through the American Petroleum Institute (API) to the point that today, >4.20 g/cm3 has

The cost of barite has increased over since 2009, while availability of API-grade 4.2-SG barite has dwindled in the past several years due to supply, transportation, political, or other issues. As a result, the industry has shifted to 4.1 specific gravity (SG) barite to extend the barite reserves. A recent study

As highlighted in Figures 1 and 2, barite has a particle size distribution that ranges from 1 micron to 100 microns (predominantly ultra-fine and fine solids). API specifies that barite should achieve a size distribution where the percentage of material >75μm is minimized, while ensuring that the percentage of

Average particle density should not be confused with bulk density (as often given in the Material Safety Data Sheet), which is a measure of the density of the packaged material. The LeChatelier flask method is the standard for determination of the average particle density of barite and hematite [API 13A]. In this method, one measures the ...

Current American Petroleum Institute (API) specifications (API 13A, 1996) permit as much as 30% of barite to be finer than 6µ in size, and much of this 30% can be assumed to be colloidal when purchased. Pure barium sulfate is a very soft mineral, but the hardness of commercial barite depends on the impurities associated with it.

The typical particle size of barite is similar to Class G oil-well cement. The barite used as a weighting material for cement must have a specific gravity of about 4.2 g/cm 3 to meet the API specifications.

The influence of particle size distribution of barite on reduction process has been investigated. At first, an industrial barite ore was selected and the complete chemical and mineralogical analyses were identified by X-ray method. As shown in Table 1, the main mineral was barite and small quantities of quartz were found.
