Abstract: The present invention relates in general to a system to protect and monitor production and non-production oil and gas wells. The present invention provides an oil or gas well and field integrity system for a well which passes through at least one subterranean formation containing pressurized formation fluids. The system comprising at least one oil or gas well located within a designated oil or gas field; and at least one bund wall formed within a target zone of the at least one subterranean formation, each bund extending along at least a portion of a perimeter surrounding the oil or gas field or along at least a portion of a section surrounding one or more oil or gas wells within the oil or gas field to assist in maintaining hydrostatic pressure on at least one side of the bund wall within the target zone thereby reducing the possibility of subsidence within the oil or gas field.

Abstract: This invention relates in general to the detection and containment of leaking gas and fluids from around wellheads of a well site. The system comprising: at least one perforated or slotted pipe adapted to be placed adjacent a wellhead and having holes sized to allow the transmission of liquid and gas into the pipe, wherein the liquid or gas are leaking from and around the wellhead conductive pipe and the wellhead; a flexible cover, covering at least the adjacent areas around the wellhead and the at least one perforated or slotted pipe; and a fluid detector in fluid communication with the at least one perforated or slotted pipe.

The present invention provides an oil or gas well and field integrity system for a well which passes through at least one subterranean formation containing pressurised formation fluids. The system comprising at least one oil or gas well located within a designated oil or gas field; and at least one bund wall formed within a target zone of the at least one subterranean formation, each bund extending along at least a portion of a perimeter surrounding the oil or gas field or along at least a portion of a section surrounding one or more oil or gas wells within the oil or gas field to assist in maintaining hydrostatic pressure on at least one side of the bund wall within the target zone thereby reducing the possibility of subsidence within the oil or gas field.
