Description
Dissolvable Frac Plug
Features & benefits
⚫ Full 10,000psi(70Mpa) differential pressure rating between stages;
⚫ Big bore ID to facilitate immediate flowback and well clean up, full bore ID is achieved after complete dissolution;
⚫ Unique shear ring design eliminating normal steel shear screws for releasing;
⚫ Eliminate the risk and cost associated with conventional plug removal;
⚫ Simplistic three piece design and compact construction;
⚫ Integrated anti-preset feature;
⚫ Low dissolvable rubber content;
⚫ Easy to operate, can be run with wireline or tubing string;
⚫ Should drilling out is needed in special circumstance, the Afrac Big Bore Dissolvable Plug has good drillability, can be easily drilled out by milling tool.
