Abstract

Dalam upaya untuk mempertahankan produksinya di lapangan X, PT. XYZ melakukan pekerjaan Well Intervention terhadap sumur-sumur yang ada. Rencana kerja Well Intervention dibuat setiap tahunnya oleh fungsi Exploitation berupa usulan & proposal pekerjaan Well Intervention, yang kemudian dilakukan prioritasi dan penjadwalan pengerjaan rencana kerja Well Intervention tersebut. Kondisi saat ini, PT. XYZ belum mempunyai pedoman resmi untuk menentukan prioritas rencana kerja Well Intervention, akibatnya penentuan prioritas menjadi subyektif, kurang terukur dan tidak konsisten. Melalui penelitian ini diharapkan penentuan prioritas rencana kerja dapat dilakukan secara obyektif dan terukur. Metode pengambilan keputusan untuk menentukan bobot kriteria-subkriteria yang penting menggunakan metode AHP, sedangkan untuk prioritasi alternatif menggunakan Metode TOPSIS. Kombinasi AHP-TOPSIS dipilih untuk meminimalkan kelemahan Metode AHP pada penggunaan alternatif yang banyak, yang akan memperumit proses perbandingan berpasangan, maka dari itu dipilih kombinasi dengan metode TOPSIS yang mempunyai bentuk yang lebih sederhana dalam penentuan prioritas alternatifnya. Hasil penelitian yang diperoleh adalah kriteria Gain Produksi memiliki bobot tertinggi (0,362), kemudian diikuti biaya (0,234), Tingkat Kesulitan (0,172), Durasi Pekerjaan (0,080), Kebutuhan Rig (0,078) dan Akses Jalan& Lokasi (0,073). Kemudian diperoleh hasil prioritas rencana kerja well intervention yang dibagi menjadi beberapa tingkatan prioritas sebagai berikut: 1. Sangat Prioritas: Sumur-08, Sumur-14, Sumur-11, Sumur-13, Sumur-02, Sumur-03, 2. Lebih prioritas: Sumur-01, Sumur-07, Sumur-05, Sumur-15, Sumur-09, Sumur-19, 3. Prioritas: Sumur-04, Sumur-12, Sumur-17, Sumur-23, Sumur-20, Sumur-06, 4. Kurang Prioritas: Sumur-22, Sumur-21, Sumur-18, Sumur-16, Sumur-26, Sumur-27, Sumur-10, Sumur-24, dan Sumur-25.
===============================================================================================================================
In an effort to maintain production in field X, PT. XYZ performs Well Intervention work on existing wells. The Well Intervention work plan is prepared annually by the Exploitation function in the form of suggestions & proposals for Well Intervention work, which are then prioritized and scheduled for the work on the Well Intervention work plan. Current conditions, PT. XYZ does not yet have official guidelines for determining priorities for good Intervention work plans, resulting in priorities being subjective, less measurable and inconsistent. Through this research, it is expected that priority work plans can be carried out in an objective and measurable manner. The decision-making method for determining the weight of important sub-criteria uses the AHP method, while for prioritizing alternatives using the TOPSIS method. The AHP-TOPSIS combination was chosen to minimize the weaknesses of the AHP method in using many alternatives, which would complicate the pair comparison process, therefore the combination with the TOPSIS method was chosen which has a simpler form in compiling alternative priorities. The research results obtained were that the Production Gain criteria had the highest weight (0.362), followed by cost (0.234), Difficulty Level (0.172), Work Duration (0.080), Rig Needs (0.078) and Road Access & Location (0.073). Then the results of the priority well intervention work plan with are divided into several priority levels as follows: 1. Very Priority: Well-08, Well-14, Well-11, Well-13, Well-02, Well-03, 2. More priority : Well-01, Well-07, Well-05, Well-15, Well-09, Well-19, 3. Priority: Well-04, Well-12, Well-17, Well-23, Well-20, Well -06, 4. Less Priority: Well-22, Well-21, Well-18, Well-16, Well-26, Well-27, Well-10, Well-24, and Well-25.
