... strength and permeability. A variety of strength measurements were used to understand the full impact on the resulting strength properties. Over 20 fracture embedment tests with proppants were conducted to determine the strengthening effects in the chalk face and assess the resulting permeability...

... Abstract A major North Sea operator was looking to improve production from low permeable reservoirs in mature assets. Under-displaced, high proppant concentration fracs must be pumped in an efficient manner to unlock the value potential. A new single-trip, multistage stage proppant fracturing...

... Abstract The channel fracturing technique achieves heterogeneous proppant placement by pumping pulses of proppant laden slurry and clean fluid in alternating sequence. Successful creation of proppant banks in the fracture provides stable channels of infinite conductivity which reduces pressure...
