To drill a gas well in Pennsylvania the operator needs…

  • a drilling permit
  • an E & S plan

Permits, Etc.

slide-13
SLIDE 13

Additional permits and/or approvals may be needed

  • PennDOT highway occupancy

permit

  • SRBC or DRBC Permit
  • Chapter 105 encroachment permit
  • Stormwater Management permit

for projects affecting more than 5 acres

slide-14
SLIDE 14

Drilling Permit Applications include

  • Application Fee
  • Bond
  • Any waiver or variance requests
  • PNDI check
  • Well plat
  • Political subdivision and county
  • Location of the well
  • Name of the surface owner and lessor
  • Name of all surface owners or water purveyors

whose water supplies are within 1000 ft.

  • Name of owner or operator of all underlying

workable coal seams

  • Record of Notification
  • Marcellus Addendum
slide-15
SLIDE 15

The operator shall forward by certified mail a copy of the plat to:

  • the surface owner
  • all surface owners with water supplies

and water purveyors within 1000 ft

  • all coal owners and lessee of any underlying

workable coal seams

  • all coal operators identified on the well plat.
  • Gas Storage operators within 2000 ft.
  • proof of the notification shall be sent to the Department

The operator must give 24 hr notice of the date the drilling

  • the department
  • the landowner
  • political subdivision

Locating A Well Site

  • Geology – drill where the gas is

Distance Restrictions:

  • 100 ft. - stream, spring or body of water

identified on the most current 7 ½ minute USGS topographic map.

  • 100 ft. must be maintained to any wetland

greater than one acre in size.

  • 200 ft from an existing building or water

well without written consent of the owner.

  • The department may grant a waiver to the

distance restriction.

History

Sept 29, 1972 – 25 PA Code Chapter 102 adopted. Oil & Gas Operators were required to prepare Erosion and Sediment Control plans. 1981 – Department’s First Erosion and Sediment Control Manual for oil & gas well operations (Now incorporated in the Oil and Gas Operators Manual.)

Let’s Make a Plan, Stan.

Fracing the Well

slide-36
SLIDE 36

What is Fracing? Hydraulic fracturing is the process in which fluid is pumped down a well and into a formation under pressure high enough to cause the formation to crack,

  • r fracture, forming passages through

which gas can flow into the well bore. Upon completion of the frac this fluid is pumped from the formation into a lined sump and trucked to a permitted treatment facility.

Common Questions

slide-45
SLIDE 45

Protection of Water Supplies

slide-46
SLIDE 46

“presumption of responsibility” An operator is responsible for any degradation of a water supply within 1000 ft

  • f the gas well that occurs within six months
  • f the completion of drilling, unless the
  • perator can prove otherwise.

Whenever a gas/oil well related water loss or degradation occurs it should be reported to the Bureau of Oil & Gas Mgmt. regional

  • ffice for further investigation.
slide-47
SLIDE 47

What happens to the fluids used during drilling and production?

All fluids encountered during the drilling and fracing of a gas well are collected in lined sumps.
