Well integrity

Assuring well casing integrity and quality

The Offshore Installations and Wells (Design and Construction) Regulations (DCR) require the well operator to ensure that there is no release of fluids from the well so far as is reasonably practicable. There are also requirements of the Borehole Sites and Operations Regulations (BSOR) that are important for maintaining well integrity.

The integrity of oil and gas wells is ensured through a combination of:

Maintaining well integrity

Well design and construction operations follow a recognised industry standard and construction as detailed in UKOOG shale Gas Guidelines and Oil and Gas UK Well Life Cycle Integrity Guidelines together with API Guidance such as the API Guidance Document HF1 – 'Hydraulic Fracturing Operations – Well Construction and Integrity Guidelines'). Such processes ensure that wells have safety features incorporated into their design. Specific design and construction requirements include:
