Work under a cross-functional subsurface team, and with other department (drilling, surface engineering) by collaborating on Ijen exploration and development campaign (30 - 110 MW) :- Numerical simulation (natural state, history matching, production forecast) for the development phase, based on exploration phase result (conceptual model, well testing, geochemistry). - Wellbore simulation analysis based on the production forecast model, used for assessing the steam-field and power-plant design. - Well targeting assessment to secure enough steam supply and to assess future development phase together with geoscientist. - Well testing planning & design, analysis & report, and supervision on-site together with production engineer.

• Working onshore on measurement/logging-while-drilling data acquisition for directional wells (J-shape, S-shape) including horizontal wells. • Experienced in overbalanced & underbalanced drilling, hole problems situation (total loss circulation, stuck pipe, high/low pressure, high temperature), anti-collision issue, and sidetrack well.• Successfully drilled 50+ oil & gas wells & 10+ geothermal wells for several companies across Indonesia, most often as the Lead Engineer.Responsibility:• Manage inventory on-site & organize material and equipment’s movement.• Prepare unit and build measurement (Mud Pulse or Electromagnetic system) and logging tools (PWD, DGR, EWR, ADR, ALD & CTN) as per hole section & drilling parameter.• Deliver good quality data of inclination & azimuth, pressure, temperature, vibration, and data log (gamma-resistivity, azimuthal/imaging resistivity, neutron density & porosity) in realtime and recorded mode to the client.• Promote drilling optimization & hole problem precaution from realtime bottom hole vibration, ECD, and temperature measurements.• Cooperate with directional driller & geosteering to maximise hydrocarbon production.Projects: - Chevron Pacific Indonesia (Minas, Duri, Balam, Bangko, Petapahan, Kotabatak, Ubi, Jorang)- Medco Energy (Kaji)- Supreme Energy (Rantau Dedap)- Pertamina Geothermal Energy (Tompaso, Lahendong)- VICO Indonesia (Nilam)- Sarulla Operation Limited (Namora-I-Langit, Silangkitang)
