This document is specifically for wells drilled and completed onshore, although many of the provisions are applicable to wells in coastal waters.ġ.3 This document does not attempt to address the full well life cycle of well operations although a brief paragraph on fracture stimulation for re-entries is included in 5.10. controllable- fracture design and execution parameters.ġ.2 The guidance from this document covers recommendations for pressure containment barrier design and well construction practices for onshore wells that will undergo hydraulic fracture stimulation. established- well barriers and integrity as created during well construction
existing- formation parameters with associated range of uncertainties Fracture containment combines those parameters that are existing, those that can be established at installation, and those that can be controlled during execution: contains and isolates the produced fluids.ī) Fracture containment: the design and execution of hydraulic fracturing treatments to contain the resulting fracture within a prescribed geologic interval. delivers and executes a hydraulic fracture treatment, and protects and isolates useable quality groundwater, The provisions in this document relate to the following two areas.Ī) Well integrity: the design and installation of well equipment to a standard that Hydraulic Fracturing-Well Integrity and Fracture Containment First Editionġ.1 This document contains recommended practices for onshore well construction and fracture stimulation design and execution as it relates to well integrity and fracture containment.
The operator is responsible for determining compliance with applicable legal and regulatory requirements. This document does not constitute legal advice regarding compliance with legal or contractual requirements or risk mitigation. This document provides non-technical guidance only, and practices included herein cannot be applicable in all regions and/or circumstances. These guidelines are intended primarily to support onshore oil and gas projects in the United States for shale developments however, they can be adapted to any oil and gas projects in the United States. Operators can have different approaches to addressing the concerns and issues. Working together with stakeholders to seek mutually agreeable solutions is an important aspect of community engagement. Some of these interests can be in direct conflict with one another. Operators recognize that stakeholders within the community can have different interests, issues and levels of concern. The use of these guidelines is at each individual operator’s discretion. These suggested guidelines are typical and reasonable and generally apply under normal operating circumstances. Many operators already apply similar guidelines or processes within their operations. It provides flexible and adaptable strategies, recognizing that application will vary from operator to operator and community to community. It is designed to acknowledge challenges and impacts that occur during the industry’s presence in a given region. Conscientious operators are committed to helping communities achieve positive and long-lasting benefits.īoth local stakeholders and operators can use this guidance. Principles of integrity, transparency and consideration for community concerns underpin responsible operations. Oil and gas operators acknowledge the challenges associated with industry activities, which can include challenges important to a community. These guidelines outline what local communities and other key stakeholders can expect from operators. This standard is not applicable to onsite repair at the equipment installation site.Ĭommunity Engagement Guidelines First Edition, July 2014 Equipment identified as manufactured in conformance with API 6A prior to April 1986 (API 6A, 15th Edition) is outside the scope of this document. This standard applies to equipment manufactured to editions of API 6A in which a product specification level (PSL) identifies the quality, material, and testing requirements for a specific product. This standard identifies the requirements for repair and remanufacture of wellhead and tree equipment manufactured in conformance with API Specification 6A for continued service when specified by the user/ purchaser of the equipment.
