709.     Requirements relating to wells.

The well-operator1 must ensure that a well2 is so designed, modified, commissioned, constructed, equipped, operated, maintained, suspended and abandoned that so far as is reasonably practicable3 there can be no unplanned escape of fluids from the well and that risks to the health and safety of persons from it or anything in it, or in strata to which it is connected, are as low as is reasonably practicable4.

Before the design of a well is commenced the well-operator must cause the geological strata and formations, and fluids within them, through which it may pass, and any hazards which such strata and formations may contain, to be assessed5.
