such Forms or Schedules with the Securities and Exchange Commission and any
stock exchange, self-regulatory association or any other authority; and

(3)	take any other actions of any type whatsoever in connection with the
foregoing that, in the opinion of each such attorney-in-fact, may be of benefit
to, in the best interest of, or legally required of the undersigned, it being

The undersigned hereby grants to each attorney-in-fact  full power and authority
to do and perform all and every act and thing whatsoever requisite, necessary or
proper to be done in the exercise of any of the rights and powers herein
granted, as fully to all intents and purposes as the undersigned might or could
do if personally present, with full power of substitution or revocation, hereby
ratifying and confirming all that the attorney-in-fact, or the
attorney-in-fact's substitutes or substitute, shall lawfully do or cause to be
done by virtue of this Power of Attorney and the rights and powers herein
granted. The undersigned acknowledges that the foregoing attorneys-in-fact, and
their substitutes, in serving in such capacity at the request of the
undersigned, are not assuming (nor is Oasis Petroleum Inc. assuming) any of the
undersigned's responsibilities to comply with Section 16 of the Securities
Exchange Act of 1934.

The undersigned agrees that each such attorney-in-fact may rely entirely on
information furnished orally or in writing by the undersigned to the

Oasis Petroleum Inc. and each such attorney-in-fact against any losses, claims,
damages or liabilities (or actions  in these respects) that arise out of or are
based upon any untrue statements or omissions of necessary facts in the
information provided by the undersigned to such attorney-in-fact for purposes of
executing, acknowledging,  delivering or filing Form 3, 4 or 5, Form 144 or
Schedule 13D or 13G (including amendments thereto) and agrees to reimburse Oasis
Petroleum Inc. and the attorney-in-fact on demand for any legal or other
expenses reasonably incurred in connection  with investigating or defending
against any such loss, claim, damage, liability or action.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5, Form 144 and
Schedules 13D and 13G (including amendments thereto) with respect to the
undersigned's holdings of and transactions in securities issued by Oasis
Petroleum Inc., unless earlier revoked by the undersigned in a signed writing
delivered to the foregoing attorneys-in-fact.  This Power of Attorney revokes
all other powers of attorney that the undersigned has previously granted
concerning the matters described herein.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of the date written below.
