Drilling

As per Azar Oil Field Master Development Plan, 18 new wells will be drilled to the depth of 4,700 meters in sarvak formation and existing well (AZ-02) will be worked-over as producer well. Above drilling scope has been awarded to three local company as EPDS contract with utilizing totally six drilling unit 2000 HP.

Azar Oil Field is one of the most complicated and challenging drilling operation in the region, necessitating most accurate engineering and operational computations. Difficulties in casing design influenced by differences in formation pressure regimes, necessity of using heavy drilling fluid (83-148 pcf) with  intermittent low and high pressure zones, heavy casing strings (almost equal to rig capacity), long open hole intervals, high H2S content and unexploded mines remaining from battle filed are the most problems in the Azar field.
