Downhole measures cut sand production from Turkmen offshore wells

Offshore staff

ASHGABAT, TurkmenistanDragon Oil has completed drilling and initial testing of the Dzheitune (Lam) 28/169 development well in the Cheleken Contract Area (CCA) of the Caspian Sea.

The well was completed as a single producer to a depth of 2,010 m (6,600 ft), and tested at 1,775 b/d of oil. The drilling rig has skidded to the platform’s next slot to spud the Dzheitune (Lam) 28/172 well.

Early last month, the company choked down various older wells to minimize sand ingress that was impacting oil flow. Gradually these wells are being restored to normal flow levels through installation of sand screens, as well as desanders on certain platforms in areas prone to sand production.  

Over the last two years, Dragon has installed sand screens on newer wells to control sand production and to ensure effective oil flow from well completions. The company will continue this action in 2012. Last year, the company also installed a desander on the Dzheitune (Lam) 63 platform.

Dragon is forecasting average first-half production from its CCA facilities to be 10-15% more than the 58,000 b/d achieved during 1H 2011. It expects to exceed 70,000 b/d in July. More wells could be drilled in addition to those all ready planned.
