This part of ISO 6142 specifies a gravimetric method for the preparation of calibration gas mixtures in cylinders with traceable values for the amount-of-substance fraction (amount fraction) of one or more components. This part of ISO 6142 describes a method for calculating the uncertainty associated with the amount fraction of each component. This uncertainty calculation requires the evaluation of the contributions to the uncertainty due to factors including the weighing process, the purity of the components, the stability of the mixture, and the verification of the final mixture.This part of ISO 6142 is only applicable to mixtures of gaseous or totally vaporized components, which may be introduced into the cylinder in the gaseous or liquid state. Both binary and multi-component gas mixtures (including natural-gas type mixtures) are covered by this part of ISO 6142. Methods for the batch production of more than one mixture in a single process are not included in this part of ISO 6142.This part of ISO 6142 requires estimation of the stability of the mixture for its intended life time (maximum storage life), but it is not for use with components that react with each other unintentionally. This part of ISO 6142 also requires the impurities in each parent gas or liquid used in the preparation of the mixture to be assessed and quantified.

This document provides content and requirements for the design of multi-component thermal fluid huff and puff workflow during heavy oil fields development.

This document is applicable to the full cycle of heavy oil reservoir development with various reservoir characteristics including thin layers, thick layers, edge and bottom water, and medium and deep depth.

This document specifies the functional requirements and principles for design, operation and requalification of pipelines in the petroleum and natural gas industries using reliability-based limit state methods as permitted by ISO 13623. Reliability-based limit state methods provide a systematic way to predict pipeline safety in design and operation. This document supplements ISO 13623 and can be used in cases where ISO 13623 does not provide specific guidance and where limit states methods can be applied, such as, but not limited to, — qualification of new concepts, e.g. when new technology is applied or for design scenarios where industry experience is limited, — re-qualification of the pipeline due to a changed design basis, such as service-life extension or change of the transported fluid, which can include reduced or increased uncertainties due to improved integrity monitoring and operational experience or limited information on pipeline properties relevant to the new service — collapse under external pressure in deep water, — extreme loads, such as seismic loads (e.g. at a fault crossing), ice loads (e.g. by impact from ice keels), — situations where strain-based criteria can be appropriate. This document applies to rigid metallic pipelines on-land and offshore used in oil and gas industries including lower carbon energy.

This document provides requirements for side-pocket mandrels used in the petroleum and natural gas industry. This document includes specifying, selecting, designing, manufacturing, quality control, testing, and preparation for shipping of side-pocket mandrels. This document addresses standard side-pocket mandrel designs as well as high pressure and/or high temperature (HPHT) equipment rated greater than 103,43 MPa (15,000 psi) and/or greater than 177 °C (350 °F) wellbore conditions as proffered by API 1PER15K-1. This document does not address nor include requirements for end connections between the side-pocket mandrels and the well conduit. The installation and retrieval of side-pocket mandrels is outside the scope of this specification. Additionally, this document does not include specifications for center-set mandrels, mandrels that employ or support tubing-retrievable flow control devices or side-pocket mandrels that incorporate non-metallic materials for pressure containment. This document does not include gas-lift or any other flow-control valves or devices, latches, and/or associated wire line equipment that can or cannot be covered in other API specifications. The side-pocket mandrels to which this document refers are independent devices that can accept installation of flow control or other devices down-hole. This document is a supplement to API Spec 19G1, 2nd edition (2019), the requirements of which are applicable with the exceptions specified in this document.
