Exhibit 10.6

                           Purchase and Sale Agreement
                   (Enerhance- Superior Medicine Hat Property)

This  agreement  (the  "Agreement")  is  entered  into on April 24,  2006 by and
between Enerhance Energy,  Inc. of Calgary,  Alberta,  Canada  ("Enerhance") and
Superior Oil and Gas Co. of Yukon, Oklahoma ("Superior").

In  consideration  of the  representations  and promises  set forth  below,  the
parties agree as follows:

1.  Representations by Enerhance.  Enerhance has an agreement with EOG Resources
Canada that provides Enerhance the ability to acquire a 100% working interest in
natural  gas  leases  covering  seven  sections  of land  (4,480  acres)  in the
producing Medicine Hat Sands in the Many Islands/Walsh  Area, Township 13, Range
2, W4M, Alberta,  Canada.  Enerhance believes it has the ability to earn, from a
third company,  Direct  Energy,  the rights to the shallower Milk River Sands in
the same seven  sections  by drilling  five wells on the leased  lands by August
2006.

2.  Representations  by  Superior.  Superior  desires to obtain the Medicine Hat
Sands rights of Enerhance set forth in its agreement  with EOG Resources  Canada
("the Enerhance-EOG Contract Rights"). Superior is also interested in acquiring,
by farm-in,  the rights to the Milk River Sands if the farm-in  agreement can be
negotiated  for Superior by Enerhance  on  favorable  terms ("the Direct  Energy
Farm-In").

3. Sale and Purchase of Enerhance-EOG Contract Rights.  Enerhance agrees to sell
to Superior,  for $350,000,  the  Enerhance-EOG  Contract  Rights,  and Superior
agrees to purchase  from  Enerhance  on or before May 2, 2006 the  Enerhance-EOG
Contract Rights for $350,000, subject to the following provisions:

     3.1 Enerhance will receive an overriding royalty of 15%, provided, however,
     that the Enerhance  overriding  royalty plus all other royalties  burdening
     the  Medicine  Hat Sands shall not exceed 20%,  which may require  that the
     Enerhance  royalty be reduced  to an amount  less than 15% ("the  Enerhance
     Overriding Royalty").

     3.2 All  royalties  burdening  the  properties  must  pay  their  share  of
     "Operating  Costs" but pay no part of the wells' "Capital Costs." Royalties
     are  calculated  on Operating  Revenue,  not Gross  Revenue.  Capital Costs
     include costs such as drilling and completions,  pipelining, and subsequent
     work-over  costs.  Operating  Costs  include  monthly  clean  out  costs to
     maintain production, field and in-house chargeable costs, processing costs,
     compression  costs , surface  lease  charges,  and normal well  repairs not
     requiring a service rig.

4. Milk River Sands  Farm-In.  Superior  encourages  Enerhance to negotiate  for
Superior  a  farm-in  agreement  with  Direct  Energy on the Milk  River  Sands.
Provided the farm-in is on terms  agreeable to Superior,  Enerhance will receive
an overriding  royalty burdening the Milk River Sands identical to the Enerhance
Overriding Royalty.
