16、ed in some API standards. It has been of extreme usefulness in minimizing fire hazards associated with petroleum processing. It has also been a universal sealing material, compatible with most refining fluid services. Certain serious adverse health effects are associated with asbestos, among them th

17、e serious and often fatal diseases of lung cancer, asbestosis, and mesothelioma (a cancer of the chest and abdominal linings). The degree of exposure to asbestos varies with the product and the work practices involved. Consult the most recent edition of the Occupational Safety and Health Administrat

18、ion (OSHA), U.S. Department of Labor, Occupational Safety and Health Standards for Asbestos, Tremolite, Anthophyllite, and Actinolite, 29 Code of Federal Regulations Section 1910.1001; the U.S. Environmental Protection Agency, National Emission Standard for Asbestos, 40 Code of Federal Regulations S

19、ection 61.140 through 61.156; and the U.S. Environmental Protection Agency (EPA) rule on labelling requirements and phased banning of asbestos products (Sections 763.160-170). There are currently in use and under development a number of substitute materials to replace asbestos in certain application

20、s. Manufacturers and users are encouraged to develop and use effective substitute materials that can meet the specifications, for and operating requirement of, the equipment to which they would apply.

37、1 Barite is used to increase the density of oil well drilling fluids. It is a mined product that can contain significant quantities of minerals other than barium sulfate, which is its main component. 1.2 A list of some minerals commonly associated with barite ores is given in Table 1 with the chemic

38、al formulas, mineralogical names, and the densities of the mineral grains. 1.3 The performance of barite in a drilling fluid is related in part to the percentage and type of non-barite minerals distributed in the barite ore. Some of these minerals have little or no effect on drilling fluid propertie

39、s, but others can degrade these properties and even be harmful to rig personnel. 1.4 It is the objective of this publication to provide a comprehensive, detailed description of the chemical analytical procedures for quantitatively determining the mineral and chemical constituents of barite. These pr

40、ocedures are quite elaborate and will normally be carried out in a well-equipped laboratory. 2 Normative References The following referenced documents are indispensable for the application of this document.
