The well integrity standard should provide guidance to the oil and gas industry on how to effectively manage well integrity during the well operational condition. The "Well Operational Condition" is defined as, the well life cycle from the handover of the construction phase to the abandonment phase, assuring compliance with the defined safe operating envelope. The standard shall address the process of managing well integrity, by identified well types based on exposure of risk to people, environment, assets and reputation that is supported by associated maintenance / monitoring plans, technical reviews and management of change as detailed in following steps:
1 A pro-active well / field review monitoring process for wells' safe operating envelope to include changes in flow parameters, gas or effluent composition, annuli pressure communication, corrosion or wear, that re-assures the wells operate safely within their boundaries. Changes to the operating envelopes shall be recorded and the associated assurance task for maintenance and monitoring of well conditions shall be updated.
2 Well types defined based on environment (onshore, offshore, subsea) and functionality (injector, producer, artificial lift, gas, oil, water) with their operating envelopes or barrier elements specified. The requirements for barrier elements shall be based on well outflow potential risk and severity of impact to the environment. The well type defines the inspection and maintenance frequency of the barriers defined to minimise the risk to environment, people, assets and reputation.
3 Risk based monitoring and maintenance plans based on well type and risk exposure that assure wells are maintained within their safe operating envelopes. To minimize the risk of uncontrolled release of hydrocarbons, or associated products from the production or injection activities to the environment (atmosphere / sea / swamp / land or aquifers), throughout the life cycle of each well.
