Abstract
A work platform (10) for use in well operations, the work platform (10) being configured for positioning above a well pipe (15), the work platform (10) having a support frame (12), a support tool (13) arranged on the support frame (12), the support tool (13) operable to engage a lubricator (14) and vertically and horizontally support the lubricator (14), wherein the support frame (12) is movable between an advanced position and a retracted position. There is also provided an assembly for carrying out well operations comprising a wireline mast (11), and methods of inserting and retrieving a tool string into or from a well pipe (15).
Claims22
A work platform for use with a wireline mast in well operations, the wireline mast comprising one or more hoisting wires for hoisting and suspending a lubricator, the work platform configured for positioning above a well pipe, the work platform comprising:
- a support frame;
- and
- a support tool arranged on the support frame, wherein:
- the support tool is operable to engage the lubricator;
- the support tool is operable to support and fix the lubricator vertically and horizontally independently of the wireline mast and hoisting wires;
- and
- the support frame is movable between an advanced position and a retracted position relative to the well pipe and wireline mast.
A method of inserting a tool string into a well pipe, comprising:
- providing a work platform comprising:
- a support frame movable between an advanced position and a retracted position;
- and
- a support tool arranged on the support frame;
- hanging off a lower part of the tool string in the well pipe;
- operating, by means of the work platform, the support tool to engage a lubricator, wherein:
- the support tool supports and fixes the lubricator vertically and horizontally;
- and
- the lubricator comprises an upper part of the tool string in a position above the well pipe;
- connecting, while supporting and fixing the lubricator in the position above the well pipe with the support tool, the upper part of the tool string and the lower part of the tool string;
- and
- connecting the lubricator to the well pipe.
A method for retrieving a tool string from a well pipe, comprising;
- providing a work platform comprising
- a support frame movable between an advanced position and a retracted position;
- and
- a support tool arranged on the support frame;
- operating, by means of the work platform, the support tool to engage a lubricator,
- wherein:
- the support tool supports and fixes the lubricator vertically and horizontally;
- and
- the lubricator comprises an upper part of the tool string in a position above the well pipe:
- disconnecting the lubricator from the well pipe;
- and
- disconnecting, while supporting and fixing the lubricator in the position above the well pipe with the support tool, the upper part of the tool string from a lower part of the tool string.
