Azerbaijan, Baku, 8 April / Trend / A sidetrack will be built in an exploration well in the Inam field in the Azerbaijani section of the Caspian sea, a source near the project told Trend .
A sharp drop in steam pressure and loss of return in the annular area occurred during a sidetrack drilling in INX-2 on Inam under the 7" final casing. Attempts to restore circulation with the use of the drilling mixture of low pressure failed due to pressure occurring in an open track. As a result, BP, a project operator, decided to cement this section of the well and drill a sidetrack up to the project depth of 5,350 m.
According to experts, a drop in steam pressure in the upper layers of Fasile Svita may have indirectly resulted in the tectonic fault of the well.
The well is drilled in the contract area which covers approximately 225 sq m in some 140km south of Baku. The water depth in the contract area varies from 45 m to the north to 200 m to the south. The minimum depth of the Inam bank is four m.
The partners to the Inam project are the State Oil Company of Azerbaijan Republic (50%), BP (25%, operator), the Korean National Oil Corporation (20%) and Shell (5%).
