Abstract
Device, system, and method to adhesively bond a sleeve to a mandrel are disclosed. The sleeve and the mandrel may be used as part of frac plug or a bridge plug in oil and gas applications. The bonded adhesive connection with grooves is strengthened to reliably achieve higher levels of lap shear strengths than attainable by conventional means.
