The WOS Sherman Drillable Cement Retainer is a hybrid mixed media design, isolating certain intervals of the wellbore and prevents the flow of fluids between those sections. This allows for squeeze operations to be conducted by placing cement, resign or other fluid barriers behind the casing while preventing it flowing back into the work string. Paired with the WOS Victory Series Bridge Plug below and stinger assembly above, the operator can activate the plug valve that can be opened by manipulation of the work string, sting in and out testing above and below the plug to verify seal integrity to ensure proper placement of fluids. After a desired amount of fluid is pumped through the cement retainer the operator can sting out of the plug ensuring the pressure integrity of the squeeze operation below the plug. The WOS Sherman Retainer combines years of industry expertise into a product that is reliable, efficient, and adjustable based on customer needs. All Victory Series plugs are designed in-house by WOS and wholly manufactured, thus allowing for exclusive customization for specialty operations.
