Deruitn Dissolveable Face Plug
Deruitn dissolvable frac plug is an extende-range,fully dissolable frac plug that provides a dependable method for temporary zonal isolation during frac operations in both vertical and horizontal completions.The slim-ODdesign allows for the plug to be run thruugh casing restrictions such as casing patches and set in standard API casing.Deruitn eliminates milling and post-frac cleanout leaving no debris to remove from the well,especially important with a reduced ID restriction in the casing.
Description
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 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.
