API RP 13C-2010 pdf free download.Recommended Practice on Drilling Fluids Processing Systems Evaluation.
1 Scope This International Standard provides a standard procedure for assessing and modifying performance of solids control equipment systems commonly used in the field in petroleum and natural gas drilling fluids processing. This procedure is not intended for the comparison of similar types of individual pieces of equipment. Clause 11 in this document replaces Clause 11 currently in the ISO 13501:2005. It specifies a different labelling requirement for shale shaker screens that will be permanently attached to the screen. It also covers the marking of shipping containers for shale shaker screens. This International Standard Annex B provides a standard procedure for quick assessment of a solids control screen sizing. The method can be used in the field or laboratory for identification of an unknown screen approximate size range. It is provided for information only and does not replace or supplement the normative testing shown in Clauses 9 through Clause 11 in this document. This procedure is not intended for the operating comparison or ranking of similar types of individual pieces of equipment. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 3310-1, Test sieves — Technical requirements and testing — Part 1: Test sieves of metal wire cloth ANSI/AWWA Standard C700, Cold-water meters — Displacement type, bronze main case API, Manual of Petroleum Measurement Standards, Chapter 5.3—Measurement of Liquid Hydrocarbon by Turbine Meters 3 Terms, definitions, symbols and abbreviated terms For the purposes of this document, the following terms and definitions apply. 3.1 Terms and definitions 3.1.6 API sand 〈physical description〉 particles in a drilling fluid that are too large to pass through a 74 μm sieve (API 200 screen) NOTE 1 Its amount is expressed as a volume fraction (percent) of drilling fluid. NOTE 2 Particle size is a descriptive term; the particles can be shale, limestone, wood, gold or any other material. 3.1.7 API screen number mesh, obsolete mesh count, obsolete number in an API system used to designate the D100 separation range of a mesh screen cloth cf. D100 separation (3.1.23) NOTE 1 The term mesh was formerly used to refer to the number of openings (and fraction thereof) per linear inch in a screen, counted in both directions from the centre of a wire. This term is being replaced by the API screen number. NOTE 2 Mesh count was formerly used to describe the fineness of a square or rectangular mesh screen cloth. For example, a mesh count such as 30 × 30 or often 30 mesh indicates a square mesh, while a designation such as 70 x 30 mesh indicates rectangular mesh. This term is being replaced by the API screen number. NOTE See 9.6 for further information. 3.1.8 backing plate support plate attached to the back of screen cloth(s) 3.1.9 baffle plate or obstruction built into a compartment to change the direction of fluid flow 3.1.10 barite baryte natural barium sulfate (BaSO 4 ) used for increasing the density of drilling fluids NOTE International Standards require a minimum specific gravity of 4,20 for barite, but do not specify that the material must be barium sulfate. Commercial ISO 13500 barite can be produced from a single ore or a blend of ores, and can be a straight-mined product or processed by flotation methods. It can contain accessory minerals other than barium sulfate (BaSO 4 ). Because of mineral impurities, commercial barite can vary in colour from off-white to grey to red or brown. Common accessory minerals are silicates such as quartz and chert, carbonate compounds such as siderite and dolomite, and metallic oxide and sulfide compounds.
