Influence factors for production of dual-lateral well in multilayer heterogeneous reservoirs;

Well Jing 31-59 is the first bi-lateral horizontal well of China located in Jing 17 block of Shenyang oilfield.

Application of expansion positioning multilateral well technology in Chengbei oilfield, Bohai Sea;

Onshore horizontal well system consists of L-shaped horizontal wells,casing sidetrack horizontal wells,multilateral wells,multi-step horizontal wells,horizontal multilateral and interconnecting horizontal wells,etc.

The results indicate that Shengli Oilfield is able to design and accomplish horizontal multilateral wells by itself.

Recover low permeability high pour-point oil reservoir inblock Jing17 by side-tracking horizontal well and lateral well;

Xinjiang Drilling Technology Research Institute has finished the field test in DC024 lateral well which is first (TAML) four-stage difficulty well at Chepaizi well field of Kelmayi low-efficiency oilfield in December 2005.

Based on the stage completions and principles of the completion designs of lateral wells , the plastic cementing techniques in two lateral horizontal wells are introduced in detail.

Experimental study of electric analog for the percolation characteristics of multilateral wells at immediate vicinity of wellbore

The calculation model of steam distribution for thermal recovery of heavy oil reservoirs using multilateral wells
