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.
