Well development surge blocks built for wells finished with K-Packer style stainless steel well completions. Each block threads directly onto a surge/sample rod through a female connection sized to match the K-Packer coupling, so you can surge the screen interval to set the gravel pack, break up drilling fines, and pull silt out of the screen slots before pumping the well clean.

Available in 2" (1-1/4" female thread connection) and 4" (2" female thread connection) sizes.
