Frac Plug with Sealing Element Compression Mechanism

A frac plug comprising:

• a plug body, comprising:
• a first sub having a taper extending along a portion of an outer surface, and
• a second sub threadably engaged with the first sub;
• a slip circumferentially disposed about the plug body between the first sub and the second sub, the slip configured to expand and couple the frac plug to a tubular section;
• a sealing element circumferentially disposed about the first sub, the sealing element configured to create a seal between the plug body and an inner surface of the tubular section;
• and
• a compression ring having a tapered inner surface, the compression ring circumferentially disposed about the first sub and abutting the sealing element, and configured to expand when shifted along the taper of the first sub to compress the sealing element and retain the sealing element in a compressed position.

A method for setting a frac plug within a tubular section disposed in a wellbore, the method comprising:

• disposing the frac plug on a running tool;
• positioning the frac plug within the tubular section using the running tool;
• compressing the frac plug with the running tool;
• shifting a compression ring of the frac plug along an outer surface of the frac plug to expand the compression ring and compress a sealing element of the frac plug to create a seal between the frac plug and an inner surface of the tubular section, wherein friction between the compression ring and a plug body of the frac plug prevents movement of the compression ring away from the sealing element;
• and
• engaging a left-hand thread pattern defined in an outer surface of a slip of the frac plug with the inner surface of the tubular section to retain the frac plug within the tubular section.
