ADL Completions

Development of Russian Multilateral Completion Technologies

Run in Hole

Multilateral well

The solutions offered by ADL Completions will allow producing from all side tracks of a multilateral well and enable precise re-entry into the main and sidetracks during production. We offer solutions suitable for new wells and existing multilateral wells with casing strings of any size.

Advantages:

Larger reservoir exposure delivered by drilling additional sidetracks.

Less rig time for replicated solutions.

Added production from thin layers.

Less capital expenditures for upper completion.

Construction of TAML 1 wells in challenging geological and downhole environments.
Case study:
1. Problems encountered while drilling the main bore resulted in a sub-horizontal wellbore trajectory (93° at the whipstock landing depth), making it more difficult to install the ADL Completions LLC equipment;
2. The main wellbore liner was run in one trip on an anchor packer to 3,800 m depth where the azimuthal location of the orienting sub was taken;
3. The hollow whipstock was run and stabbed onto the anchor packer with a mill assembly, then oriented in the specified azimuthal direction during one trip;
4. A 2.5-m casing window was cut and a 4-m rathole was drilled. Total milling time is 8.5 hours.

Construction of TAML 1 well in a thin reservoir.
Case study:
1. A 520-m long main bore liner was run during one trip on the anchor packer, then azimuthal location of the orienting sub was taken using a standalone orienting device;
2. The hollow whipstock was run and stabbed onto the anchor packer with a mill assembly, then oriented in the specified azimuthal direction during one trip;
4. A 2.5-m casing window was cut and a 5-m rathole was drilled. Total milling time is 7.5 hours.
4. Flow rate at well start-up was higher than in the offset wells completed on the same field by competing contractors.

Construction of TAML2 well completed by a third-party contractor. The job was complicated by having no depth reference, well azimuth and exact window cutting data.
Case study:
1. The whipstock assembly was promptly supplemented by a casing window locator;
2. The casing window was located and the assembly was activated during one trip;
3. The window was milled providing access to the side track;
4. Hydrochloric acid treatment was successfully completed in the side track;
5. Under customer instruction, the whipstock was retrieved to surface together with the anchor.
