One of the major challenges in determining actual annular pressure losses is that the non-Newtonian fluid flow in annular conduit is much more complex than pipe flow. Many investigators proposed different equivalent diameter concepts to link annular flow to well defined...

For these experiments a special stain steel holder was designed allowing an open space around a core of 30 cm long and 5 cm in diameter, simulating a matrix with surrounding fractures. Carbon dioxide and normal decane were used as solvent and oil, respectively. While all experiments were...

... to recover and improve oil production in related mature reservoirs. A new technique called small-diameter separate-layer hydraulic fracturing is investigated for those damaged wells whose diameter is above 105 mm. Fracturing string and its matching tools are specially designed and tested, including packer...
