Hvis man ser lidt på de udfordringer der har været tidligere, vil man genkende billede, ud fra at det er de samme udfordringer vi har pt. : Fra August 2000.

Muradkhanli is potentially the largest onshore field in Azerbaijan, with estimated oil in place of approximately 5 billion bbl. It lies about 70 miles west of Baku near the rail oil export line to Tblisi and Sepsa, Georgia and is strategically located near the planned Baku-Ceyhan main export pipeline route.
Under terms of the PSA signed in 1998, Ramco holds a 50% interest in the field with an affiliate of Socar holding the remaining 50%. The contract area covers three proven oil accumulations: Muradkhanli, Jafarly, and Zardab, where Socar originally found some 3-5 billion bbl of oil in the field, and has produced over 22 million bbl to date, mostly from the Upper Cretaceous reservoir horizons. But production has fallen to less than 10% of the original dayrate, despite the state oil company's efforts to keep the field in operation for so long with so little resources.

Traditionally what happens is the chemical problems in the hole causes collapse.

MOC's new well (MOC-01) is only 75 meters from the previous well (Muradkhanli-208), which was drilled in 1980 and produced on DST up to 2,100 b/d, but soon became clogged due to mechanical difficulties. MOC-01 was spudded in January, drilled down to 4,567 meters, and logged, whereupon a significant oil column was identified in the fractured Middle Eocene limestones, sandstones, and volcanics, as was expected, and an unexpected additional play in the Upper Eocene fractured clastics. A number of attractive fractures were also found in the rock, but when it came to running the seven-inch line to complete the well, problems thwarted further completion. There was an attempt to complete the well through the drillpipe, but a tool was dropped and it was abandoned.
