W. T. Bell International, Inc., is an explosives specialty group that utilizes its energetic designs and hydrostatic function test capabilities to supply field-proven jet cutters and severing tools for applications ranging from low-pressure gas to 30,000-psi HPHT operations. Expansion Charges, the latest custom product development in collaboration with Royal Dutch Shell, efficiently remediate leakages through microannuli or small channels in the cement by means of plastically deforming the pipe and densifying the cement, thereby sealing off leak paths. Royal Dutch Shell reports a 95% success rate over 19 fields tests. Regional regulatory agencies in Canada, the U.S. and Europe have approved the use of Expansion Charges for plug and abandonment and other well intervention operations. The company was founded In 2002 by William T. Bell and James (Jim) Rairigh, who have a combined 100+ years of experience in oilfield explosives applications and pipe recovery. Jim Rairigh continues to operate the company since Mr. Bell’s passing in 2017.
