On July 16th Drilling Innovation in cooperation with the Krasnoyarsk branch of Siberian Service Company CC set a whipstock in open hole (well no. 604, Dulisma oil and gas condensate field, East Siberia). The Customer is Dulisma Oil Co.

After drilling a pilot hole and confirming the availability of useful hydrocarbons the Customer decided to install the whipstock above the reservoir, with a view to drill a horizontal section of the well.

The drilling team under management of Mr. Savin V.N. began cementing the well spacing, which revealed the producing formation.On received cement plug at 9074 ft. depth was installed and cemented the whipstock.

Our company has conducted whipstock orientation with the compact telemetry system GNOM-1. Whipstock was oriented in the 11L sighting angle. Accuracy of orientation was confirmed by data received from the downhole telemetry system while drilling the second bore hole.
