This document specifies the principles, instruments, materials and experimental conditions for testing Young’s modulus and Poisson’s ratio using triaxial testing method. It also specifies the sampling and mechanical testing procedures, as well as the method and precision requirements for calculating shale mechanical brittleness index based on Young’s modulus and Poisson’s ratio. This document is applicable to reservoir quality evaluation and sweet spot identification in shale gas production.

This document specifies the requirements, sampling, testing, inspection and accompanying documents of slick water. This document is applicable to fracturing fluid systems used in hydraulic fracturing operations in shale gas.

This document specifies how to design and operate allocation systems for gas production facilities. It describes the most common types, principles and methods used for the allocation of gas and associated liquids. The objective is to provide an approach to current best practice in the oil and gas industry. It applies to gas and liquid allocations to be performed in production, processing, transportation, storage and terminal installations dealing with natural gas and associated liquids as well as end products like sales gas, liquefied petroleum gas (LPG), liquefied natural gas (LNG), condensate and to some extend non-hydrocarbon gases like CO2, H2. This document provides the minimum information needed to develop and implement allocation procedures and systems both for internal purposes (well allocation) and fiscal or commercial applications with different owners and stakeholders. This document can be used to develop gas and liquid processing and transportation agreements and regulatory documents as well as to conduct audit of measurement and allocation systems. It also introduces the areas of competence needed and the terminology used in the industry.

This document specifies a method for the determination of drag reduction of slick water, which is mainly used to evaluate the drag reduction performance of slick water. This document uses the pipeline method to evaluate the drag reduction, which is currently recognized as the best method to evaluate the drag reduction performance. This document describes the device, experimental conditions and operating steps in detail. The drag reduction value obtained by evaluation according to this document can effectively represent the on-site drag reduction performance.

This document describes a laser Raman spectroscopy method for the quantitative determination of chemical composition of natural gas in upstream area.

This document specifies a method for the determination of hydrogen sulfide content in working field natural gas of upstream area by laser absorption spectroscopy. The analytical range expressed as mole fraction is 10 × 10−6 to 20 %. The analytical range can be expanded to higher content with specific instrument requirements.

ISO/TS 14749:2016 concerns the determination of hydrocarbon components up to C7+ in natural gas in upstream petroleum industry, which describes the principle of operation of GC and provides guidelines for selection, evaluation, and factors impacting upon its performance such as sample probe, sample conditioning, installation, operation and troubleshooting.

ISO/TR 12748:2015 describes production flow measurement of wet natural gas streams with WGFMs in surface and subsea facilities. Wet natural gas streams are gas-dominated flows with liquids like water and/or hydrocarbon liquids. ISO/TR 12748:2015 defines terms/symbols, explains the various concepts, and describes best practices of wet gas flow meter design and operation. It addresses metering techniques, testing, installation, commissioning, and operation practices such as maintenance, calibration, and verification. It also provides a theoretical background of this comprehensive, challenging and still evolving measurement technology.

ISO/TR 26762:2008 describes the production measurements, in terms of both hardware and procedures, that can be used to allocate the gas and condensate back to the individual concessions, reservoirs and wells in a fair and equitable way. The objective is to give an approach that is recognized to be current best practice and that has a wide support in the oil and gas industry.

This document specifies the principles, instruments, materials, experimental conditions and the sampling and composition analysis steps required for testing mineral composition using the X-ray diffraction method, as well as the method and precision requirements for calculating shale brittleness index based on mineral composition. This document is applicable to reservoir quality evaluation and sweet spot identification in shale gas production.

This document specifies the method and quality requirements for the determination of elemental sulfur solubility in natural gas, and is applicable to the determination of elemental sulfur solubility in sulfur-containing natural gas.
