Notional Field Development Final Report - EBN

EBN Notional Field Development Plan
4 Surface & Environmental Impacts
4.1 Project Description
The Scope of Work (SOW) for the Surface and Environmental Impacts team was to prepare a notional /
feasibility level study to identify the potential environmental issues associated with the surface impacts
associated with the development of shale gas resources within the Netherlands.
4.1.1 Assumptions
Our recommendations are based upon the data reviews, modeling and designs of the Subsurface Team,
and input from EBN. Based upon information agreed to in our Peer Review meeting on September 24,
2011, the following assumptions were used as the basis of our work.
Resource play is a “dry gas.”
Low potential for the presence of hydrogen sulfide (H 2 S).
In order to maximize the potential production volumes of the play, the development will require
horizontal drilling with hydraulic fracing. Since different lateral lengths and number/stages of
fracs were modeled, it is important to clarify that our work is based upon the following
information:
Drilling depth of 3,100 meters
o Lateral lengths of 1,500 meters on a 400-meter spacing
o Designed for 22 frac stages
o Each stage will require 3,000 barrels of water
o Flowback is projected at 15 percent (%) of injected volume
o Produced water is projected at 600 barrels per day (initial volumes could be as high as
1,000 barrels per day)
• Well pad footprint is estimated at 150 meters by 100 meters.
• For each well pad, it is estimated that between one and 10 wells can be drilled to minimize the
number of well pads required.
• Within the identified “GO” sites, the intent would be to establish centralized water
impoundments with piping systems to move the water between the well pads.
• Al surface facilities must be designed in relation to potential seismic activity.
4.1.2 Unknowns
There are still many “unknowns” at this juncture of the study, which will be reduced as decisions are
made regarding:
• Location of first area to be explored
• Capital budget to be invested
• Schedule of resources allocated.
