Construction and Testing (group effort)
Additional application include:
Perforating
Drilling
Cutting tubulars
Blowout assisted because can cut off wellheads
In mining drills holes so that dynamite may be used
Firefighting uses so that water is more coherent when spraying fires provides safer working distance as well as drilling through a building to get straight to a fire
For each statement explain the statement and what it means.
1) We are using a method proven to cut with comparatively low pressures usually 10,000 psi is used
2) Our method only water goes thru the pumps
3) We use tungsten carbide nozzles that have a high resistance to abrasive wear
4) Manish’s new method fixes the above problem.
Research thus far, performed by Manish Kumar, has been accomplished in less than ideal wellbore conditions.
We will be drilling through cores under water and vertically, better simulating actual wellbore conditions.
