SAND for ABANDonment
U.S Patent # 6,715,543
U.S. Patent # 7,258,174
Sandaband is a unique non-consolidating, non-segregating, non-shrinking and non-fracturing well plugging material. The combination of individual high-strength quartz particles with bingham-plastic properties makes Sandaband an ideal well barrier, suitable for any downhole conditions, including HPHT, CO2 and H2S.
Creating a permanent robust barrier against over-pressurised formations has always been a challenge in the petroleum industry. Temperature fluctuations, chemical degradation, subsidence, compaction, faults or minor quakes can easily stress a brittle sealing material beyond its strength, eventually permitting gas or fluid flow to adjacent zones or to the surface.
Our company, Sandaband Well Plugging AS, is the exclusive provider of the material globally, and delivers a complete solution including all necessary equipment and personnel for planning, logistics and execution of Sandaband well plugging services.
