词条 | Invisible Lost Time |
释义 |
}} Invisible Lost Time (ILT) related to routine rig drilling operations is the difference between actual operational duration and a best practice target. It is invisible because it does not appear on any conventional morning reports. The measurement of Invisible Lost Time starts by analyzing each individual key performance indicator (KPI) that can be produced by a particular crew (drilling crew, casing crew, etc.), by a machine-automated operation, or a combination of both. The measurement of Invisible Lost Time was first developed and used by Statoil and TDE.[1]
