Procedures and equipment for profiling and jointing of pipes

A method of completing a wellbore comprising:

• expanding a first tubular to a desired monobore diameter;
• forming an enlarged inner diameter at the bottom of the first tubular through expansion;
• lowering a second tubular through the first tubular;
• placing the top of the second tubular adjacent the enlarged inner diameter at the bottom of the first tubular;
• expanding the top of the second tubular into frictional contact with an interior surface of the enlarged inner diameter;
• and
• expanding the second tubular to the desired monobore diameter.

A method of forming a seal between two tubular members, the method comprising:

• providing a first tubular member having an internal surface and an external surface, the external surface describing a first diameter;
• providing at least one recess in said external surface at a seal portion of the first tubular member;
• locating a deformable sealing member in the recess such that the sealing member describes an external diameter no greater than said first diameter;
• locating the first tubular member within a second tubular member;
• and
• expanding at least the seal portion of the first tubular member such that the sealing member engages an inner surface of the second tubular member.

A seal-forming arrangement comprising:

• a first tubular member having an internal surface, and an external surface describing a first diameter, the tubular member defining at least one recess in said external surface at a deformable seal portion of the first tubular member, said seal portion having a wall thickness substantially equal to the wall thickness of the tubular member adjacent said seal portion;
• and
• a deformable sealing member in the recess, the sealing member describing an external diameter no greater than said first diameter,
• wherein expansion of at least the seal portion of the first tubular member increases the diameter of the sealing member to at least said first diameter.

A method for expanding a well bore tubular comprising:

• providing an expander having at least one radially extendable member, the radially extendable member having a first unextended position, a second fully extended position and a range of positions between the first and second positions wherein the radially extendable member moves from the first position upon application of a force to the radially extendable member;
• locating the expander proximate the well bore tubular;
• applying the force to the radially extendable member;
• engaging the radially extendable member with an inner diameter of the well bore tubular;
• and
• expanding the tubular wherein the radially extendable member is positioned within the range for at least a portion of the expansion.

A method for expanding a well bore tubular comprising:

• providing an expander having at least one radially extendable member, the radially extendable member having a first unextended position, a second fully extended position and a range of positions between the first and second positions wherein the radially extendable member moves from the first position upon application of a force to the radially extendable member and wherein at least a portion of the force remains applied during the expanding;
• locating the expander proximate the well bore tubular;
• applying the force to the radially extendable member and maintaining at least a portion of the applied force;
• engaging the radially extendable member with an inner diameter of the well bore tubular;
• and
• expanding the tubular wherein the radially extendable member is positioned within the range for at least a portion of the expansion.
