The TAML 4 multilateral completion system is a sophisticated solution for both new and sidetracking wells. The technology entails casing and cementing the junction.
The developed system maintains production from the mainbore and ensures the mechanical integrity and isolation of the window interval from the transit layers.
TAML 4 works in the numerous casing sizes from 5-3/4” up to 9-5/8” without affecting the functionality of the well. All required SIT have been done. The technology is ready for trial job.
Unstable formations
Heterogeneous rocks with transit layers (water, gas) in the kick-off area
6 trips to install the Level 4 – basic scenario
The orientation of downhole equipment is available with different orientation systems
Retrievable casing exit system is applied (similar to TAML 2)
The junction design provides full-bore ID to the mainbore and allows to RIH any type of equipment
(for example, ESP) to the planned depth, in particular, below the window interval
Deployment of diverters (permanent / retrievable) ensures selective access to the laterals;
Technology is compatible with multistage fracturing systems and sand control equipment
TAML 4 multilateral completion system has significant potential for application on old wells
casing sizes from 5-3/4” to 9-5/8”
