Abstract
An embodiment of a tool for clearing a deposit within a fluid flowline, including a body having a central axis, a first end, a second end opposite the first end, and a radially outer surface extending axially from the first end of the second end. In addition, the tool includes a first energy element coupled to the first end, and an electrode extending radially from the radially outer surface of the body. The first energy element and the electrodes are each configured to emit energy to dissipate the deposit in the fluid flowline.
Claims36
A tool for clearing a deposit within a fluid flowline, the tool comprising:
- a body having a central axis, a first end, a second end opposite the first end, and a radially outer surface extending axially from the first end to the second end;
- a first energy element coupled to the first end;
- and
- an electrode extending radially from the radially outer surface of the body;
- wherein the first energy element and the electrode are each configured to emit energy to dissipate the deposit in the fluid flowline.
A tool for clearing a deposit from a fluid flowline, the tool comprising:
- a body having a central axis, a first end, a second end opposite the first end, a radially outer surface extending axially from the first end to the second end, and a first throughbore extending axially from the first end to the second end;
- a first energy element coupled to the first end of the body, wherein the first energy element is configured to emit energy to dissipate the deposit in the flowline;
- and
- a first pumping assembly disposed in the first throughbore and configured to pump fluid through the first throughbore.
A method for clearing a deposit from a flowline, the method comprising:
- (a) moving a flowline clearance tool through the flowline toward the deposit, wherein the tool comprising:
- a body having a central axis, a first end, a second end opposite the first end, a radially outer surface extending axially from the first end to the second end, and a first throughbore extending axially from the first end to the second end;
- and
- a first energy element coupled to the first end of the body;
- (b) positioning the first energy element proximal the deposit;
- (c) directing energy emitted from the first energy element at the deposit;
- (d) jetting the deposit with fluid pumped through the throughbore of the body during (c);
- and
- (e) dissipating the deposit during (c) and (d).
