Applied onshore New Brunswick, a frac fluid based on liquid petroleum gas resulted in longer fracture half-lengths and higher production rates compared with water-based fluid.
In a Barnett shale application, the completion method provided substantial savings by eliminating the need for a coiled tubing unit and associated equipment.
A critical, though not very glamorous, segment of the deepwater oil and gas sector is riser technology. Risers provide a vital conduit for the circulation of drilling fluids and protect the drillstring in offshore drilling operations.
Generally preferred to orifice valves in offshore applications, venturi valves may not be appropriate in some cases, such as where large adjustments in gas flowrate are needed within a limited injection pressure range.
From their beginnings as a last-resort solution for operators who would otherwise have to abandon a well, expandables are gradually gaining acceptance as a planned alternative to conventional tubing—more expensive, to be sure, but sometimes a better choice.
To facilitate infill drilling at Forties field, 3D seismic data was needed to image any shallow gas accumulations, but towed streamers couldn’t acquire data beneath or near existing platforms. A nodal acquisition technology using ROV-deployed sensors filled in the blanks.
