hydraulic fracturing - instead of ceramic proppant fracturing sand

hydraulic fracturing - instead of ceramic proppant  Frac sand
     With oil and gas prices rise, the  region usher in a qualitative leap --- instead of using  Ceramic proppant   frac sand  for  Hydraulic fracturing   Some of the large oil and gas service companies have entered the Mexican market for oil and gas drilling in Mexico opened a new chapter.
    Oil and gas are usually stored in thousands of feet above the ground at the gap sedimentary reservoirs, in order to use them in the oil and gas reservoirs, wells should hit the stratum. Moreover, usually by hydraulic fracturing method the oil (gas) wells and reservoirs are connected together. hydraulic fracturing  process includes sufficient in oil and gas reservoirs in the manufacture of crack with the pressure of the liquid is injected into the well. Called proppant particulate material is fed into the cracks with liquid inside, so they can be in high-pressure injection is stopped, so that it is supporting the cracks open state.
       Proppant  filled in the cracks in the reservoir created a permeable channels, oil and gas can be more freely flow along this path. In this way, both to increase the recovery of oil and gas also increases the actual harvest oil and gas production from the well. In the modern era, due to increased demand for oil and gas production and mining technology, constantly updated, hydraulic fracturing in oil and gas drilling in general popularity. And in the past because of relatively shallow wells (below 1500), the use of  frac sand  is both convenient and cost-effective, but also can play the effect. However, contrary to the concept but with modern drilling.  Proppant  fracturing is a high strength, high conductivity, high temperature and a series of advantages, not only played a convenient drilling, but also increase the role of oil and gas production.
