What is a dual lateral well?
A multilateral well is a well with two or more laterals (horizontal, vertical, or deviated) drilled from a main mother well. This allows one well to produce from several reservoirs. Multilateral wells are suitable for complex geology where drilling more new wells to penetrate to those reservoirs is not economical.
What is complex path drilling?
Complex Path Drilling creates well paths with have multiple twists and turns to try to hit multiple accumulations from a single well location. Using this technology can be more cost effective and produce less waste and surface impacts than drilling multiple wells.
How far can horizontal drilling reach?
These technologies are capable of reaching 10,000–15,000 ft (3000–4500 m) and may reach 25,000 ft (7500 m) when used under favorable conditions.
How deep is directional boring?
Who invented horizontal drilling?
As a utility installer in Los Angeles in the early 1960s, Cherrington came up with the concept of horizontal directional drilling. While on the job, he saw another business installing a gas line nearby using a hand-held air drill. When Cherrington learned about guided drilling, he was inspired to research the subject.
What is a multilateral completion system?
Multilateral completion systems allow the drilling and completion of multiple lateral boreholes within a single mainbore. This allows for alternative well-construction strategies for vertical, inclined, horizontal, and extended-reach wells. Multilaterals can be constructed in both new and existing oil and gas wells.
What are the benefits of multilateral technology?
Benefits of multilateral technology can be enormous. Field development plans define well counts required to drain the reservoir―often with significant technical constraints and uncertainty. Multilateral well completions maximize reservoir contact per well, reducing the number of wells required.
What is the difference between the Florite and isorite multilateral completion systems?
The FloRite multilateral completion system provides TAML Level 5 junction pressure integrity and re-entry capability without pulling the upper completion. The IsoRite multilateral completion system provides through-tubing re-entry capability in TAML Level 2 and 4 wells.
What are multilateral drilling systems?
Multilateral systems combine the advantages of horizontal-drilling techniques with the ability to achieve multiple target zones. The advantages of horizontal drilling include: Better sweep efficiencies.
