  • Compaction tolerant basepipe for hydrocarbon production
    Patent number: 8479811
    Abstract: The invention relates to base pipe with slots cut into the peripheral wall to form compaction absorber segments that are arranged to permit the base pipe to be compacted in length without buckling or transferring excessive compressive forces to other pipe sections when a poorly consolidated formation shrinks due to production from the formation. Over time, the slots close as the base pipe shrinks in length and production continues through conventional holes in the base pipe.
    Type: Grant
    Filed: March 30, 2010
    Date of Patent: July 9, 2013

  • Method for inhibiting the initiation and propagation of formation fractures while drilling and casing a well
    Patent number: 5207282
    Abstract: Fracture initiation and propagation during drilling or running casing in a well are prevented or inhibited by including an effective amount of a specially sized solid particulate loss prevention material in the well fluid prior to encountering formation breakdown in a susceptible zone.
