Drilling and Reservoir management

Reservoir Management Section provides support across most of the subsurface, drilling, facility engineering disciplines and makes a major contribution in terms of how we manage, field performance, production volumes, reserves recovery, and the utilisation of equipment and operational techniques that minimise environmental impact.

Kazneft Petroleum is currently drilling 4 wells per year to complete the phase IIM for a total program of 16 wells. There are nearly 388 wells of varying categories in the Karachaganak field, of which 94 are producing wells and 17 are gas injectors as of end 2014. The remaining wells either form part of an extensive network of monitoring and observations wells or are abandoned exploration or production wells.
Kazneft Petroleum currently has two drilling rigs and one work over rig (2 frac units, 2 coiled tubing units and 3 clean-up and testing units), and when needed a specialist small rig works in the field undertaking a variety of activities in support of the on-going Phase IIM development of the field. Innovations in drilling applied by Kazneft Petroleum in the Karachaganak field represent best world technologies and include the following:

• Multilateral Wells
• Flareless Well Testing & Clean Up
• Digital Oilfield
• Open Hole Packers and Variable Down Hole Chokes
• Intelligent wells’ completion
