Pertamina EP is an Indonesian national oil company which subsidiaries of PT Pertamina (Persero). For nearly 60 years, the Pertamina EP drilling area has been located onshore. In September 2017, Pertamina EP successfully conducted a Poleng N-2 well as the first drilling operation in an offshore area. Originally wells candidate's Poleng N-2, proposed in early 2017 with the target of drilling operations can be carried out on TW-3 in 2017. However, considering the acceleration of production, utilities offshore rig availability and cost efficiencies, accelerated drilling operations into TW-2 in 2017. it begins with the efforts to accelerate drilling AFE approval Poleng N-2 of SKK Migas on June 15, 2017. Short preparation was conducted with the support of SKK Migas and synergy of PHE WMO and PEP as a form of Pertamina Incorporated. Synergy is done in the form Farm in contract, Material Transfer Agreement and the exchange of information and expertise of each subsidiary, as well as support for QA / QC of internal WMO competent and experienced in drilling operations using Ensco Rig 67. So in the end, in the span of about three months, can be resolved about contract services and materials, including the preparation of internal HR by chance exposure PEP Drilling wells to WMO. Poleng field located in East Java province started operated by Pertamina EP in 2013. The drilling program Poleng N-2 of the Platform CW as the first drilling operation PEP from this field is expected to increase the production of limestone reservoir targets Kujung. As for the design of drilling a sidetrack well from the well parent CW-02H, at a depth of 5,000 ft MD ± which has a horizontal well trajectory is quite challenging on the route hole the size of 6-1 / 8 ″in length ± 2500 ft. The well completion technology also comes with Inflow Control Device (ICD) and Swell Packer on 4-1 / 2 ″Liner as part of the Lower Completion. In the end the Poleng N-2 well drilling operation can be completed in November 2017, with the status: Zero incident / accident, cost about 75% of the approved budget, the percentage of Non Productive Time is less than 5% and Initial production reached 783 BOPD above target of 700 BOPD so that production acceleration can be realized with a good economic level.
