Question

Q3 . How shale gas can be withdrawn from the deep reservoirs ?​

Answer 1

Answer:

Hydraulic fracturing – commonly known as fracking – is the process used to extract shale gas. Deep holes are drilled down into the shale rock, followed by horizontal drilling to access more of the gas reserves, as shale reserves are typically distributed horizontally rather than vertically.

Answer 2

Answer:

Required Answer:-

• We use vertical and horizontal wells for shale gas drilling or Tertiary sections.
• The well or wells which are used are planned based on sweet spot identification.
• Shale gas is usually withdrawn from the depth below that 400m .
• Because gas may not be present at such shallow depth.
