EVALUATION OF THE REALIZATION OF DEVELOPMENT WELLS IN 2021 AND 2022 AS AN EFFORT TO ACHIEVE THE VISION OF OIL AND GAS PRODUCTION OF 1 MILLION BOPD AND 12,000 MMSCFD

Abstract

The year of 2021 and 2022 are quite interesting years for the national oil and gas industry, where the number of development drills being drilled is quite massive and aggressive compared to the drilling for the last 7 years and it is the basis for the number of drillings for the coming years. In 2021, 480 wells have been drilled and 444 onstream wells. Meanwhile in 2022, it has been approved 790 development wells and the potential for an additional 100 wells. This paper discusses the realization of the production achievement from development well, viewed from the perspective of achieving the initial flow rate (Qoi and Qgi). It is hoped that from the perspective, it can represent the evaluation of the effectiveness of the development well as well as the possibility of improvements in the future.

Nationally, in 2021 the total Qoi realization was 90,180 BOPD of the 70,977 BOPD target meanwhile the total Qgi was 991 MMSCFD of the 957 MMSCFD target. If it is seen from the average Qoi achievement of 248 BOPD from the target of 204 BOPD per well, the average Qgi is 7 MMSCFD from the target of 6 MMSCFD / well. Sumatra and Natuna Islands are the areas with the highest number of drillings in 2021. The number of onstream wells are 276 wells with a total Qoi realization of 61,104 BOPD from the target of 39,889 BOPD, a total Qgi of 12 MMSCFD of the target 28 MMSCFD. For 2022, as of July 2022, 419 wells have been drilled and 329 onstream wells have been drilled. Realization of total Qoi of 50.621 BOPD from the target of 56,279 BOPD, total Qgi of 358 MMSCFD from the target of 352 MMSCFD. The future target is that by 2022, 890 wells can be drilled with a target number of onstream wells in 2022 is about 819 wells.

In general, the higher realized wells are due to the discovery of additional upside potential layers, better hydrocarbon saturation than the prognosis, also contribution from new field development projects with very good results. Meanwhile, wells with lower realizations were caused by the realization of a more downdip structural layer, the character of the lens and changes in facies, the realization of lower hydrocarbon saturation and pressure, also operational constraints on drilling and well completion. Referring to the drilling success in 2021 and 2022, improving optimism as the efforts to increase national oil and gas production and to achieve the national oil and gas production target of 1 million BOPD and 12,000 MMSCFD in 2030. Another important effort to achieve this is the discovery from exploration drilling and implementation of the EOR program in potential fields. Certainly, commitment and good cooperation from all parties are needed to achieve the mission of the national oil and gas industry.
