Today I had sad news. My sister’s boyfriend’s father passed away. The other news is a gas well under my surveillance has gone. The gas rate has come to zero. One of my duty as a surveillance engineer at my company is to watch over wells and try to save it from declining to zero rate or dead.
This is my first well that went die under my duty. So this well produce more than 5 MMscfd after being perforated. WIth flowline pressure around 300 psi, this well was categorized as LP well (Low Pressure). The well showed such rapid decline just like after it was perforated. Before I was on duty at 2nd Jan 2013, I haven’t noticed this well at all. Then, POP!!! in 5 days, it went 0 scfd.
I believe that this is a learning for every new surveillance engineer or any fresh graduate engineer to be more detailed and focus and remain calm anytime and anywhere. Just like Sherlock, he spends some seconds to think and remain calm. So goodbye that new perforated zone.
LP wells will decline naturally, and that’s my job to monitor it. Before it dies, we need to switch it to lower system (VLP : Very Low Pressure system) within the condition of flowline availability. And I hope the petroleum engineers (PE) in Jakarta will be fine and accept this newbie’s mistake to learn more. Eventually, the PE will make additional perforation program if any productive zones exist.
Remember always work safely guys!!! Think, STOP and report , just like 3 Safety Golden Rules of VICO Indonesia.
