In high-density well fields, sidetracking from the low side of a horizontal well offers a safer and more efficient path to untapped reservoir zones. This blog explores the engineering challenge of whipstock sag in horizontal wells and introduces a field-validated anchoring solution that actively tilts the whipstock to eliminate obstruction—enabling clean casing exits without complex steering systems.
Milling operations in P&A can lead to stuck section mills, posing serious retrieval challenges. This blog explores the engineering of a high-strength Emergency Disconnect tool that withstands torsional and tensile milling loads yet breaks reliably on command. Through optimized geometry and controlled metallurgy, the tool balances strength with precision, ensuring safe recovery when disconnection is the only option.
