  • Logging plug with high integrity internal seal
    Patent number: 7819184
    Abstract: A logging plug is disclosed having an internal sealing mechanism therein which provides a high degree of sealing integrity between the bore of the plug and a coiled tubing or other means of suspending wellbore equipment running therethrough. The sealing mechanism utilizes a combination of low friction, elastomerically-energized cap seals and ring seals to ensure that the sealing surfaces adapt continuously to the changing profile of the coiled tubing to provide a true dynamic seal around the coiled tubing.
    Type: Grant
    Filed: June 21, 2005
    Date of Patent: October 26, 2010
    Assignee: Schlumberger Technology Corporation
    Inventors: Sandeep Sachdeva, Marc McCorry, Andrew S. Ferguson
  • Process for preparation of ring-substituted 8-aminoquinoline analogs as antimalarial agents
    Patent number: 6979740
    Abstract: The present invention is concerned with the development of novel 8-aminoquinoline analogs in the treatment and prevention of malaria and the said compound has broad spectrum of activity against the blood as well as tissue stages of the human malaria parasites makes these compounds very attractive in the cure and prevention of malaria caused by drug-sensitive and multidrug resistant strains and also it is expected that development of these compounds as ideal antimalarial agents may lead to suppression as well as radical cure of the malaria infection with single drug therapy.
