Freehold, They are using a packers plus system. The completion string consists of 8 sliding sleeves and 16 (minimum) packers. Each packer will be approximately 70m apart and a sliding sleeve between them. The packers are on the outside of the casing and isolate each frac zone. 8 balls slightly increasing in size are used to open the sleeves. Basically, the smallest ball goes in and is pumped to a cup (forgotten technical term) aligning with the bottom sliding sleeve. They pressure up and pop the sleeves open. They then go in with tubing conveyed pipe and pump lead fluid, followed by main including propant (certain sized sand grains all of the same size, this keeps the frac open). Then they pump down the next ball and the same done again. After it is all completed they will go down and drill out all of the balls and flow back. Sorry if you already knew this.

Halliburton doesn't own the technology. A separate company owns the completion equipment. Halliburton, own the pumping units.

Sorry about the long post.its a little more in depth than this but the general gist.

Should each stage go well and all fracs are completed without sanding out, I personally think we could see some good results. This is all IMO, always dyor.
