A Houston-based oilfield services firm has unveiled a new shale technology which enhances hydraulic fracturing, reduces overall pumping time and increases contact with the reservoir.

Baker Hughes on Thursday announced a new FracPoint MP sleeve. Combined with DirectConnect, ports and building on the FracPoint completion technique, the technology provides increased contact with the reservoir, offering more controlled hydraulic fracture initiation points and improving connectivity to the pay zone, the oilfield services provider said in a press release.

The new shale equipment allows operators to fracture through five sleeves per stage with as many as 17 stages per well, Baker Hughes claims, in addition to connecting with the reservoir through as many as 85 sleeves and 680 ports.

The system uses openhole packers to isolate multiple stages and ball-activated sleeves to divert the fracturing treatment into the formation. With the new FracPoint MP sleeve, a single ball is used to open five sleeves per stage. Each sleeve includes eight DirectConnect ports placed 45 degrees apart over the extension of the sleeve, Baker Hughes added.

“At each stage, a ball is dropped, the sleeves are opened and hydraulic pressure pushes the telescoping DirectConnect ports into the formation at high velocity. The ports act like chisels to initiate fractures at controlled points along the wellbore. This results in accurate placement of the fracture treatment and better connectivity to the reservoir,” the oilfield service firm said.
