MOC president, says that Socar was not able to exploit Muradkhanli's Middle Eocene reservoir because of completion problems—it is a reservoir prone to produce solids and is an high pressure play. Traditionally what happens is the chemical problems in the hole causes collapse.
"Our mandate is to drill the well quickly and complete it in such a way to prevent or inhibit the solids production and to sustain the production volume as well. Our strategy is to drill the well where previous Socar wells showed high productivity on test but difficulties in producing the well. So it's a risk project, but not in the sense that the oil or source rock or the trap needs to be proven. The risk here is the difficulty in completing the well to sustain the production—an engineering risk."

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. (See "Ramco Sets Casing on First Azeri Onshore Well".)
MOC then decided to sidetrack this well, which commenced in mid-June, with drilling through mid-July. Considerable flow is anticipated on tests, but sustained commercial levels of production have to be verified. Seismic is scheduled for the field, then a few appraisal wells so that, by the end of 2001, there should be a clear picture of the extent of recoverable reserves. Known already, however, is that it will require considerable fracturing throughout the field, and extensive horizontal drilling. By 2002, if appraisals are successful, a comprehensive field development program will be put in place covering both the Rehabilitation Area and the new Exploration Area, with potential oil production in excess of 100,000 b/d of oil.
