  • Successfully led and completed key projects, including the development of a comprehensive database for stuck pipe incidents and the creation of an Excel-based template for documenting post-incident investigation results.
  • Led the engineering team in revising drilling procedures for a complex gas field, which resulted in: A reduction in Days Per Well (DPW) from 60 to 28 days, (cementin completion)
    Achieved through a redesign of the well architecture to a slim-hole configuration and a transition from Water-Based Mud (WBM) to Synthetic-Based Mud (SBM),
    These optimizations reduced well costs from €10 million to €4.5 million per well. (Bustuchin wells)
  • Contributed to the feasibility assessment and implementation of casing drilling technology, including casing and bit selection, as well as performance analysis. (Tintea)
  • Operated on rigs with hook loads ranging from 75 to 350 tons.

Well Design Responsibilities:

  • Planning of well trajectories,
  • Casing and drill string design,
  • Hydraulic optimization,
  • Time and mud performance analysis,
  • Involvement in Blowout Preventer (BOP) selection and sizing.

Additional Responsibilities:

  • Accountable for drilling projects and the integration of new technologies. (USR)
