Abstract
A plug for use in wellbore operations includes a plug body extending from a top end to a bottom end; a sealing member as part of the plug body and positioned at the bottom end; and a non-rotating profile positioned at the bottom end of the plug body; the sealing member protrudes past the non-rotating profile such that the sealing member comes into contact with a surface when the plug is dropped into a well before the non-rotating profile.
Claims17
A plug for use in wellbore operations, the plug comprising:
- a plug body extending from a top end to a bottom end;
- a sealing member positioned at the bottom end of the plug body, the sealing member being composed of an elastomeric material;
- and
- a non-rotating profile positioned at the bottom end of the plug body;
- wherein the sealing member protrudes past the non-rotating profile such that the sealing member comes into contact with a surface before the non-rotating profile;
- wherein the sealing member is configured to depress against the surface until the sealing member no longer protrudes past the non-rotating profile;
- and
- wherein depression of the sealing member until the sealing member no longer protrudes past the non-rotating profile is required for the non-rotating profile to be engageable with a downhole apparatus.

A wellbore assembly, comprising:
- an apparatus run into and secured within a well, the apparatus having a landing surface;
- a plug configured to run into the well above the apparatus, the plug having:
- a plug body extending from a top end to a bottom end;
- a sealing member positioned at the bottom end of the plug body, the sealing member composed of an elastomeric material;
- and
- a first non-rotating profile positioned at the bottom end of the plug body;
- wherein the sealing member protrudes past the first non-rotating profile;
- wherein the sealing member comes into contact with the landing surface and is configured to depress against the landing surface;
- wherein depression of the sealing member until the sealing member no longer protrudes past the first non-rotating profile is required for the non-rotating profile to be engageable with the apparatus;
- and
- wherein an application of pressure or weight to the plug is required in order for the sealing member to depress against the landing surface.
