Schlumberger is trading 4.05% up now at $57.24, with no clear company-specific catalyst identified.

  • The advance extends from the August 27 close of $55.01.
  • No August 28, 2026 company-specific announcement clearly explains the move. A Reuters report updated August 28 described Schlumberger’s Venezuela oilfield-data contract; the news originally appeared August 25 and does not explicitly link to today’s trading.
  • Major U.S. indexes are lower; monitor trading for additional disclosures before assigning a definitive cause.
