Ladies and Gentlemen:
Pursuant to your
request, DeGolyer and
MacNaughton has performed a
process review of
the processes and
controls used within
ConocoPhillips in preparing
its internal estimates
of proved
reserves, as of
December 31, 2019.
This process review,
which is contemplated by Item
1202 (a)(8) of Regulation
S–K of the United States
Securities and
Exchange Commission
(SEC), has been
performed specifically
to address the
adequacy and
effectiveness of
ConocoPhillips’ internal processes
and controls relative to
its estimation
of proved reserves in compliance with
Rules 4–10(a) (1)–(32) of Regulation S–X of the SEC.
DeGolyer and
MacNaughton has
participated as
an independent
member of
the internal
ConocoPhillips
Reserves Compliance Assessment Team
in reviews and
discussions with each
of the relevant
ConocoPhillips business
units relative
to SEC
proved reserves
estimation. DeGolyer
and MacNaughton
has participated
in the
review of
all
major fields
in all
countries in
which ConocoPhillips
has proved
reserves worldwide,
which ConocoPhillips
has
indicated represents over 90 percent of its estimated total proved reserves as of December 31, 2019.
The reviews with ConocoPhillips’ technical
staff involved presentations and
discussions of a) basic reservoir
data, including seismic
data, well-log data,
pressure and production
tests, core analysis,
pressure-volume-temperature
data, and production history, b) technical methods employed
in SEC proved reserves estimation, including performance
analysis, geology,
mapping, and volumetric
estimates, c) economic analysis,
and d) commercial assessment,
including
the legal
basis for
the interest
in the
reserves, primarily
related to
lease agreements
and other
petroleum license
agreements, such as concession and production sharing agreements.
A field examination of the properties was not considered necessary for the purposes of this review of
ConocoPhillips’ processes and controls.
