Sustainable Oil and Gas Operations
Through Innovation & Technology

We apply various innovations and technology applications to find new oil and gas sources and maximize production from mature fields to support the achievement of national oil and gas production targets.

We continue to invest in finding new oil and gas reserves and maximize production from onshore and offshore oil and gas fields in the Kalimantan region. We keep developing new ideas based on research, joint learning with experts at Pertamina, and long experience in the oil and gas industry to create various technological innovations.

We implement various methods and innovations to accelerate drilling operations while significantly reducing costs. One of them is the Hydraulic Workover Unit (HWU), the first technology in the Pertamina Group and Indonesia to reduce drilling rigs. The HWU has been used to drill more than five delta wells in WK Mahakam operated by PT Pertamina Hulu Mahakam (PHM) and has proven to save up to an average of 37% of drilling costs using conventional rigs.

We have successfully implemented several innovations to maximize reserves and production increase through systematic, effective, and efficient seismic interpretation activities, management of low-pressure wells, and reactivation and optimization of abandoned wells. We used the SISCA (Hybrid Seismic and Multi Cone Analysis) method to map and quantify the volumetric gas reservoir in the shallow zone throughout the Sisi Nubi field, successfully increased new reserves by 159 Bcf. We also implemented the Permanent Coil Tubing Gas Lift (PCTGL) to produce gas in old wells with low pressure and optimize surface facilities. The Low-Low Pressure (LLP) method is also proven to reduce gas pressure already in the low-pressure phase, extending the gas production life to be longer than expected. Another supporting method is the RESA method (Effective Recompletion of Abandoned Wells), which is carried out by reentering abandoned CBM (Coal Bed Methane) wells and installing tubing cemented all the way to the surface. The exploitation of abandoned CBM wells can save around tens of billions of rupiah in costs and has a shorter operational time of about 12 days than other methods. Production continues despite earlier prediction that the wells would be non-productive.

We also continue to innovate to maintain reservoir pressure conditions, control sand, water, and scale. The Sand Consolidation method in WK Mahakam is done by injecting chemical compounds into reservoirs in shallow zones with sand problems. This innovation saved up to millions of dollars per well in costs when compared to conventional methods. We also apply Scale/Sediment Removal technology to overcome scale/sediment clogging the flow of hydrocarbons so that oil and gas reserves in the well can continue to be produced. This technology can save up to billions of rupiah per well compared to conventional methods. We also use the Robot (Robust Outflow) method to increase production capacity by utilizing available equipment to minimize modification costs and avoid production loss. This innovation increased the revenue of sandy well’s production by trillions of rupiah.

We keep innovating to support safe, effective, efficient, and faster oil and gas operations. We developed the Casing While Drilling method, which is a method that combines drilling and casing installation simultaneously. This method was carried out in the Bekapai field, dubbed as the first done by an oil and gas company in Southeast Asia, in an 805-meter-deep well for a shallow gas reservoir. There is also the SPIRALTUBE method to overcome the absence of gas leak detection devices at the Tunu well. This innovation increased gas production to 435 MMscf, or equivalent to tens of billions of rupiah. The OPTIDRILL innovation is also a method that shortens the drilling time of re-entry wells by eliminating invisible lost time in several drilling stages, thus increased cost efficiency. OPTIDRILL reduced well-drilling costs by around 40% of the total cost, equivalent to hundreds of billions of rupiah. An offshore well in WK Mahakam implemented the OPTIDRIL method, and the completion time was reduced by 56% (from 30 days to 15 days) after more than 50 years of operation.

We also improve the oil and gas operations’ efficiency, effectiveness, and safety through the Cement packer (Ceker) innovation, an isolation method by injecting cement into the annulus between the tubing and casing to access productive zones above the production packer. Ceker is an alternative/substitute for conventional production packers. This innovation shows a satisfactory level of success, and all is done without using a rig (rigless). The CEKER method has contributed 0.3 BCF and 269 MBO (1.8 BCFe). There is also FANA (Frame Anti Lama), an innovation to replace scaffolding that utilizes a more rigid, simple, and flexible (adjustable) frame structure to support the work of raising and lowering the BOP (Blowout Preventer), riser, and RJU (Rotor Jack). FANA also serves as a safer work area for personnel when removing and reinstalling rods and PCPs. This innovation accelerated construction and dismantling time to around 3.91 days per well, saved tens of billions of rupiah, and increased oil production.
