... of LWP with density equal to density of silica sand, but with higher crush resistance, provides improved proppant transport inside the fracture without loss of conductivity. Hence, this type of proppant is the optimum propping agent corresponding to both - conditions of reservoir and fracturing goals...

... a conductive channel from the formation back to the well bore. Here in Appalachia, sand is the propping agent of choice used in most all fracs. Those fracs where sand is not used would be in deeper wells requiring a proppant with higher crush resistance than that of sand or those fracs where no propping agent...

... in-situ permeability should be reproduced as far as possible. A previous work6 demonstrated that, at least for sand, the most important parameters for the fracture conductivity can be classified as follows: Stresses applied on the propping agent and fracture width, temperature, pore fluid. The stress...

Abstract Production increases resulting from fracture treatments should be based on the conductivity and location of the propping agent - not on the area created by the frac fluid. Model studies show that in conventional fracture treatments propping agents...

..., one may conclude that it is always better to use finer sand to increase the propped area of the fracture. This is not always true. Coarser sands are more conductive and can transmit more fluid to the wellbore. Because the propping agent creates a conductive fracture, proppant selection should be based...

... of propped fractures is a goal for production enhancement. The conductivity of a propped fracture is significantly influenced by in-situ stresses. Under high closure stresses ~4,000 psi or more!, sand is significantly crushed and loses conductivity. A new surface-modification agent ~SMA! allows proppant...

With high initial drawdown pressure, the proppant pack of small mesh sand with insufficient conductivity becomes a choke on the overall...
