Abstract

Blok X dari suatu perusahaan migas telah menggunakan Electrical Submersible Pump (ESP) pada 83% sumur produksi. Dengan jumlah yang besar ini, setiap kegagalan pada ESP akan berdampak langsung pada produksi lapangan. Adapun tujuan dari penelitian ini adalah untuk melakukan analisa reliability pada Pompa, Protector, dan Motor, sebagai dasar rekomendasi penggantian komponen ESP untuk tiap-sumur ESP di blok X dengan menggunakan pendekatan Weibull dalam merepresentasikan distribusi waktu kegagalan. Weibull dipilih sebagai metode yang digunakan karena fleksibilitas penggunaannya untuk memodelkan waktu kegagalan terhadap beragam tipe system dan komponen serta cukup akurat pada sampel data yang tidak terlalu banyak. Hasil penelitian menunjukkan bahwa pompa merupakan komponen yang mengalami kegagalan paling cepat diikuti oleh motor setelahnya dan protector menjadi komponen paling akhir mengalami kegagalan. Dengan batasan nilai reliability minimum yang digunakan di lapangan, motor direkomendasikan dilakukan penggantian pada 2.396 hari, protector pada 2,542 hari dan 2.088 hari untuk pompa. Perusahaan dapat melakukan saving sebesar $372.000 dari kegagalan mendadak karena delay produksi dengan melakukan penggantiaan terencana. Berdasarkan hasil assessment proses bisnis, terdapat dua proses bisnis berkaitan dengan pemeliharaan ESP yang dapat diefisiensikan dengan penggunaan tools visualisasi dashboard yang telah disiapkan.

Block X of an oil & gas company has utilized Electrical Submersible Pump (ESP) in 83% of its production wells. Given this high quantity, field productivity will be directly impacted by any ESP malfunction. The aim of this study is to use the Weibull technique to depict the failure time distribution and perform reliability analysis on the Pump, Protector, and Motor in order to provide recommendations for ESP component replacement for each ESP well in block X. Weibull was selected as the technique of choice because to its accuracy on a small sample of data and its versatility in modeling failure times for different types of systems and components. The results show that the pump is the component that fails the fastest followed by the motor afterwards and the protector is the last component to fail. With 20% reliability as minimum reliability value in field, it is recommended to replace the motor after 2,396 days, the protector after 2,542 days, and the pump after 2,088 days. By implementing scheduled replacements, the organization may save $372.000 from unexpected failures caused by manufacturing delays. The results of the business process evaluation indicate that the use of the ready-made dashboard visualization tools can expedite two business processes associated with ESP maintenance.
