The third generation of Deruitn was designed based on the field proven technology and experience from the traditional Frac Plug. With lots of field application, there are two main problems found. One is that part of the plug is not completely dissolved, and milling is still needed in the later stage, or the dissolution is too fast. The other is the high cost. Deruitn ' third-generation Thankful Dissolvable Bridge Plug has been tested with various materials on the basis of summing up the results of the previous two generations of bridge plug in the field and finalized.
