The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13503-3 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 3, Drilling and completion fluids, and well cements. ISO 13503 consists of the following parts, under the general title Petroleum and natural gas industries Completion fluids and materials: Part 1: Measurement of viscous properties of completion fluids Part 3: Testing of heavy brines The following parts are under preparation: Part 2: Measurement of properties of proppants used in hydraulic fracturing and gravel packing operations Part 4: Procedure for measuring stimulation and gravel-pack fluid leakoff under static conditions Part 5: Procedure for measuring the long-term conductivity of proppants EN ISO 13503-3:2005 Licensed Copy: London South Bank University, London South Bank University, Wed Oct 17 01:20:50 GMT+00:00 2007, Uncontrolled Copy, (c) BSI vi Introduction This part of ISO 13503 covers heavy brines commonly used in petroleum and natural gas completion, workover and drill-in fluids. These brines can be purchased or rented from multiple sources, and are available worldwide. No single source or limited source of supply is included, either by inference or reference. Annexes A to F are given for information. EN ISO 13503-3:2005 Licensed Copy: London South Bank University, London South Bank University, Wed Oct 17 01:20:50 GMT+00:00 2007, Uncontrolled Copy, (c) BSI 1 Petroleum and natural gas industries Completion fluids and materials Part 3: Testing of heavy brines 1 Scope This part of ISO 13503 covers the physical properties, potential contaminants and test procedures for heavy brine fluids manufactured for use in oil and gas well drilling, completion and workover fluids. This part of ISO 13503 provides methods for assessing the performance and physical characteristics of heavy brines for use in field operations. It includes procedures for evaluating the density or specific gravity, the clarity or amount of particulate matter carried in the brine, the crystallization point or the temperature (both ambient and under pressure) at which the brines make the transition between liquid and solid, the pH, and iron contamination. It also contains a discussion of gas hydrate formation and mitigation, brine viscosity, corrosion testing, buffering capacity and a standardised reporting form. This part of ISO 13503 is intended for the use of manufacturers, service companies and end-users of heavy brines. 2 Normative references The following referenced documents are indispensable for the application of this document.
