BLOWOUT PREVENTION AND WELL CONTROL

Training Syllabus:
BLOWOUT PREVENTION AND WELL CONTROL

INTRODUCTION :
• 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)

TRAINING BENEFIT :
• 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.
