Pak Rovicky, Ga perlu orang drilling kalau cuma masalah Loss diikuti kick. Pak Rovicky juga kalau mau ngulik sebentar pasti akan paham.
Loss..mud di hole hilang. Tidak ada mud tidak ada Hydrostatic Pressure yang melawan Formation Pressure. Tidak ada yang melawan FP, yah kontan lah semua isi di lubang (well) keluar semua..(ini diawali dgn Gain, lalu Kick, dan ditutup oleh Blow out). Definisi kick dan istilah2 drilling yg lain itu bisa di browse di SLB.com. ( http://www.glossary.oilfield.slb.com/Display.cfm?Term=kick) "kick 1. *n.* [Drilling] ID: 1454 A flow of reservoir<http://www.glossary.oilfield.slb.com/Display.cfm?Term=reservoir>fluids into the wellbore during drilling operations. The kick is physically caused by the pressure<http://www.glossary.oilfield.slb.com/Display.cfm?Term=pressure>in the wellbore being less than that of the formation <http://www.glossary.oilfield.slb.com/Display.cfm?Term=formation>fluids, thus causing flow. This condition of lower wellbore pressure than the formation is caused in two ways. First, if the mud weight is too low, then the hydrostatic pressure exerted on the formation by the fluid column may be insufficient to hold the formation fluid<http://www.glossary.oilfield.slb.com/Display.cfm?Term=formation%20fluid>in the formation. This can happen if the mud density is suddenly lightened or is not to specification to begin with, or if a drilled formation has a higher pressure than anticipated. This type of kick might be called an underbalanced<http://www.glossary.oilfield.slb.com/Display.cfm?Term=underbalanced>kick. The second way a kick can occur is if dynamic and transient fluid pressure effects, usually due to motion of the drillstring<http://www.glossary.oilfield.slb.com/Display.cfm?Term=drillstring>or casing <http://www.glossary.oilfield.slb.com/Display.cfm?Term=casing>, effectively lower the pressure in the wellbore below that of the formation. This second kick type could be called an induced kick."
