Project Name: well TK908DH, in Tahe Oilfield of SINOPEC

Operation Time: March, 2004

Operation Site: Tahe Oilfield

Project Background

The deepest Multi-lateral Well in china onshore.

Solution

· First branch hole TD 5,234m with horizontal displacement of 754m; 

· Second branch hole TD 5,239m with horizontal displacement of 700m; 

· Both two branch holes were run with casing, slotted screen and ECP packer, and selectively cemented; 

· Window-diverter was used to provide connectivity of two wellbores and selection of multi-lateral entry.

Achievement

· Petro-king provided services in all operations from completion design, tools selection to installation and construction. By its precise well arrangement and strict construction, eventually completed the well safely and efficiently, daily producing oil 160 m3/D.

· Development and promotion of multi-lateral well technology in deep oil and gas reservoirs, facilitated cost saving, environmental protection and significant efficiency.
