In relation to a well (other than a well sunk for the purpose of the abstraction of water)—
(a) a blow-out (which includes any uncontrolled flow of well-fluids from a well);
(b) the coming into operation of a blow-out prevention or diversion system to control flow of well-fluids where normal control procedures fail;
(c) the detection of hydrogen sulphide at a well or in samples of well-fluids where the responsible person did not anticipate its presence in the reservoir drawn on by the well;
(d) the taking of precautionary measures additional to any contained in the original drilling programme where a planned minimum separation distance between adjacent wells was not maintained; or
(e) the mechanical failure of any part of a well whose purpose is to prevent or limit the effect of the unintentional release of fluids from a well or a reservoir being drawn on by a well, or whose failure would cause or contribute to such a release.
