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:

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:
