Abstract
A downhole fill-up tool for use in oilfield operations, comprising a housing with a shear closing feature. The tool includes a pressure-actuated piston that triggers the shearing action, ensuring proper sealing and containment of wellbore fluids. The design of the tool allows for safe and efficient fill-up operations in challenging downhole wellbore environments.
Claims12
A fluid fill-up tool, for use downhole within a wellbore comprising:
- a) a housing having a central through bore and at least one communication port extending from an external surface of said housing to said central through bore;
- b) a sliding sleeve movably disposed within said central through bore of said housing, wherein said sliding sleeve is configured to shift between a first open position wherein said at least communication port is open and a second closed position wherein said at least one communication port is blocked by said sliding sleeve;
- c) at least one shearable member configured to secure said sliding sleeve against movement in said central through bore of said housing;
- d) a fluid piston operationally attached to said sliding sleeve, wherein said housing and said fluid piston define a chamber configured to contain compressible gas on a first side of said fluid piston, and a second communication port extends from an external surface of said housing to said central through bore on a second side of said fluid piston;
- wherein said at least one shearable member is configured to shear, and said sliding sleeve is configured to shift from said first open position to said second closed position, when a pressure differential across said fluid piston reaches a preset value.

A method for filling a downhole tool comprising:
- a) providing a fluid fill-up tool comprising:
- i) a housing having a central through bore and at least one communication port extending from an external surface of said housing to said central through bore;
- ii) a sliding sleeve movably disposed within said central through bore of said housing, wherein said sliding sleeve is configured to shift between a first open position wherein said at least communication port is open and a second closed position wherein said at least one communication port is blocked by said sliding sleeve;
- iii) at least one shearable member configured to secure said sliding sleeve against movement in said central through bore of said housing;
- iv) a fluid piston operationally attached to said sliding sleeve, wherein said housing and said fluid piston define a chamber configured to contain air at atmospheric pressure on a first side of said fluid piston, and a second communication port extends from an external surface of said housing to said central through bore on a second side of said fluid piston, and wherein said at least one shearable member is configured to shear, and said sliding sleeve is configured to shift from said first open position to said second closed position, when a pressure differential across said fluid piston reaches a preset value;
- b) conveying said fluid fill-up tool in a wellbore;
- c) shearing said at least one shearable element in response to force acting on said fluid piston;
- and
- d) shifting said sliding sleeve from said first open position wherein said at least communication port is open to said second closed position wherein said at least one communication port is blocked by said sliding sleeve.
