Blow Out Prevention and Well Control

Blow Out Prevention and Well Control BACKGROUND Merupakan salah satu masalah lubang sumur di operasi pemboran Menyebabkan timbulnya biaya ekstra yang cukup besar Berpotensi menyebabkan hilangnya sebagian atau semua fasilitas pemboran di lapangan karena kick dan blow out yang tidak terkontrol Menunda waktu produksi sumur (POP) OBJECTIVES Mengetahui gejala kejadian kick dan blow out. Mengetahui kerugian akibat kick yang tidak terkontrol atau blow out. Mengetahui usaha pencegahan terjadinya blow out. Mengetahui cara mengidentifikasi mekanisme kick yang terjadi. Mengetahui kronologi terjadinya kick dan blow out dan cara penanggulangannya dengan Well Control. PRE-REQUISITE Operator/ Sr. Operator/ Jr. Engineer/ Non Engineer Petroleum Engineers, Reservoir Engineers, Production Engineers Well Service Engineers Everybody or professionals who wants to better understanding and broaden their knowledge from the course subject COURSE OUTLINE 1.
