摘要:
A method of preventing or treating lost circulation during the drilling of a well comprises the addition, at concentration ranging between about 0.5 and 6 pounds per barrel, of water-dispersible fibers having a length between about 10 and 25 mm, for instance glass or polymer fibers, to a pumped aqueous base-fluid including solid particles having an equivalent diameter of less than 300 μm The base-fluid with the solid particles can be the drilling fluid or a small-volume pill specially pumped for curing lost circulation.
摘要:
In subsea drilling operations, workover control systems may include deployment of an umbilical from a deepwater drilling vessel. Such an umbilical provides support functions for deepwater drilling operations. In the practice of the invention, a new method, system and apparatus may be employed to deploy the umbilical independently of the drilling riser, which provides commercial and operational advantages. That is, the umbilical may be deployed at a different time than the riser is deployed, and also without intimate close connection from the umbilical to the riser.
