BLOWOUT PREVENTION AND WELL CONTROL

BLOWOUT 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 blowout yang tidak terkontrol
  • Menunda waktu produksi sumur (POP)

OBJECTIVES

  • Mengetahui gejala kejadian kick dan blowout.
  • Mengetahui kerugian akibat kick yang tidak terkontrol atau blowout.
  • Mengetahui usaha pencegahan terjadinya blowout.
  • Mengetahui cara mengidentifikasi mekanisme kick yang terjadi.
  • Mengetahui kronologi terjadinya kick dan blowout dan cara penanggulangannya dengan Well Control.
