Upgrading of hydraulic fracturing of shale dry pressing treatment should not be underestimated

Although  Fracturing proppant  of shale in the next few years may be improved or changed, however, there is not going to change the same, that is, the process of hydraulic fracturing. Shale is composed of tiny particles or clay and other chemicals to produce in the long years of high-strength reduction. This pressure makes the shale formation of layered structure, while the shale internal chemical substance decomposes it produces natural gas. With sandstone and limestone Unlike other shale tiny pores inside and not China Unicom, during which Darcy flow permeability of less than 0.01. Low permeability also requires that we must carry on shale  fracturing  .

Hydraulic fracturing is the only alternative to completely change or the improvement or the fracturing fluid. Reduce the chemical content of fracturing or water usage. A two birds with one stone initiatives is the use of liquefied petroleum gas. This product is a product of natural gas, although it is the main component of the fluid gelling propane.

Using liquefied petroleum gas  fracturing  process does not require water, but also better control of reflux.

Another option is the "dry-pressed." Dry pressure has been applied to the actual process of fracturing. Use dry sand-carrying fluid pressure when the liquid carbon dioxide will be used, and will be mixed into the  Proppant  fracturing fluid. This fracturing most commendable is that it will increase the efficiency of oil and gas production to more than five times the conventional hydraulic fracturing. However, this approach has two drawbacks fracturing. One is used in fracturing liquid carbon dioxide transport difficult, because there is no underground pipeline network, it must be by truck. The second is in the fracturing process will inevitably lead to underground ice. However, the trade-offs, the future prospects for use of this fracturing still optimistic.
