Drain Hole Stimulation System thu dao
The new Drain Hole System has the potential to 1) eliminate re-fracing, 2) stimulate 100% of the fracs in shale wells, 3) reduce re-fracing costs by 50 to 70 percent, 4) increase flow rates 50% more than refracs, and 5) release Operators from being held hostage by major oilfield service companies.
NEAR-WELLBORE DAMAGE ZONE: The major problem with fracing is that 10 foot diameter constriction zones form near the Hwell during the fracing process and continue to plug as shale wells are produced resulting in the rapid decline of the wells.
The goal of this JIP is to have 6 to 8 operators each test the new drain hole stimulation system in one of its depleted shale wells. Participants will share all data from their test wells with the other JIP Participants including drilling, completion and production data and all problems associated with the test wells including and actions taken to overcome those problems…
A four year study of fracing technical papers showed that: 1. Re-fracing is expensive, troublesome and not very effective, 2. The rapid decline is due to frac plugging near the wellbore, 3. The solution is to eliminate the near wellbore problem by drilling small drainholes …
