摘要： A milling apparatus for cutting a tubular in a wellbore includes a cutting element on a tool body configured to cut the tubular in a wellbore when the cutting element is activated when the tool is moving upward inside the tubular. The cutting element cuts the tubular to form cuttings that fall into an annulus between the tubular and the wellbore. An agitator below the cutting element agitates the cuttings in the annulus to aid the cuttings to move from the annulus into the wellbore below the milling apparatus.

摘要： A work string and method of performing a downhole operation is disclosed. The work string includes a first tool having a first ball seat configured to activate when a first activation pressure is applied to a plug seated at the first ball seat, and a second tool having a second ball seat configured to activate when a second activation pressure is applied to the plug when seated at the second ball seat, wherein the first activation pressure is different than the second activation pressure. A plug is dropped through a string in a wellbore. The first activation pressure is applied when the plug is at the first tool to activate the first tool. The second activation pressure is applied when the plug is at the second tool to activate the second tool.

摘要： Cutting elements for downhole cutting tools comprise a top surface having a cutting surface portion and a cutting profile disposed across the top surface. The cutting elements comprise first and second longitudinal side surfaces and first and second lateral side surfaces, each having a respective cross-section. The cutting profile can be disposed on the cutting surface either asymmetrically or symmetrically. Asymmetrical disposition permits two cutting elements to be arranged facing each other to cover a center point of a cutting tool. The cutting edge of asymmetrical or symmetrically disposed cutting profiles can have a shape that facilitates self-sharpening during cutting.
