Theory versus Practice
• In Theory:
An ideal solution to an important problem.
![Page 3: “Oil Field Unitization in Theory and Practice“Oil Field Unitization in Theoryand Practice” by Dr. James L. Smith Cary M. Maguire Chair in Oil & Gas Management Department of Finance](https://reader035.vdocument.in/reader035/viewer/2022062508/5ffb3a12aa89eb16606ec0ff/html5/thumbnails/3.jpg)
Theory versus Practice
• In Theory:
An ideal solution to an important problem.
• In Practice:
Imperfect adaptations are unavoidable, but
may jeopardize success.

The “Rule of Capture”…
… as explained by:
![Page 11: “Oil Field Unitization in Theory and Practice“Oil Field Unitization in Theoryand Practice” by Dr. James L. Smith Cary M. Maguire Chair in Oil & Gas Management Department of Finance](https://reader035.vdocument.in/reader035/viewer/2022062508/5ffb3a12aa89eb16606ec0ff/html5/thumbnails/11.jpg)
Excerpt from “Who Shot Mr. Burns? (Part One), aired May 21, 1995.
![Page 12: “Oil Field Unitization in Theory and Practice“Oil Field Unitization in Theoryand Practice” by Dr. James L. Smith Cary M. Maguire Chair in Oil & Gas Management Department of Finance](https://reader035.vdocument.in/reader035/viewer/2022062508/5ffb3a12aa89eb16606ec0ff/html5/thumbnails/12.jpg)
The “Rule of Capture,” as Explained by Law
• The well bore may not cross property lines.
– Mr. Burns is breaking the law.
![Page 13: “Oil Field Unitization in Theory and Practice“Oil Field Unitization in Theoryand Practice” by Dr. James L. Smith Cary M. Maguire Chair in Oil & Gas Management Department of Finance](https://reader035.vdocument.in/reader035/viewer/2022062508/5ffb3a12aa89eb16606ec0ff/html5/thumbnails/13.jpg)
The “Rule of Capture,” as Explained by Law
• The well bore may not cross property lines.
– Mr. Burns is breaking the law.
• But hydrocarbons may (and will) cross
property lines.
– Your neighbor’s vertical well is not breaking the
law.
– Without unitization, your neighbor will drill many
wells that exploit your property.

How Unitization “Solves” the Problem
• Each producer owns a share of the common
pie.
![Page 22: “Oil Field Unitization in Theory and Practice“Oil Field Unitization in Theoryand Practice” by Dr. James L. Smith Cary M. Maguire Chair in Oil & Gas Management Department of Finance](https://reader035.vdocument.in/reader035/viewer/2022062508/5ffb3a12aa89eb16606ec0ff/html5/thumbnails/22.jpg)
How Unitization “Solves” the Problem
• Each producer owns a share of the common
pie.
• Incentives are aligned; each producer want
to maximize the value of the pie, which in
turn maximizes the value of his share.
![Page 23: “Oil Field Unitization in Theory and Practice“Oil Field Unitization in Theoryand Practice” by Dr. James L. Smith Cary M.

How Unitization “Solves” the Problem
• Each producer owns a share of the common
pie.
• Incentives are aligned; each producer want
to maximize the value of the pie, which in
turn maximizes the value of his share.
• Waste that hurts any one producer, hurts all.

• Unit governance is simple: wise decisions

Problems That Remain to be Solved
• Difficulties in forming the unit…
– Bargaining and the inherent bargaining power of
small interest holders.

Problems That Remain to be Solved
• Difficulties in forming the unit…
– Bargaining and the inherent bargaining power of
small interest holders.
– Price and technological uncertainties, as they
affect the “terms of trade.”

Problems That Remain to be Solved
• Difficulties in forming the unit…
– Bargaining and the inherent bargaining power of
small interest holders.
– Price and technological uncertainties, as they

Economic Analysis of Bargaining Power
• Simplified model of two owners producing
from one field.
• Voluntary unitization is possible, but only if
the owners reach mutual agreement on:
– equity shares
– operational plan (well locations, etc.)

Government Intervention
• Well spacing and permitting regulations
replace anarchy (in the event of
disagreement) with order. This limits the
bargaining power of smaller interests.

Uncertainty Compounds the Problem
• Uncertainty and disagreement may exist
regarding the relative value of reservoir
fluids.

Uncertainty Compounds the Problem
• Uncertainty and disagreement may exist
regarding the relative value of reservoir
fluids.
– gas vs. oil

Uncertainty Compounds the Problem
• Uncertainty and disagreement may exist
regarding the relative value of reservoir
fluids.
– gas vs. oil
– primary recovery vs. secondary recovery
– royalty leases vs. production sharing contracts??

Uncertainty Compounds the Problem
• Uncertainty and disagreement may exist
regarding the relative value of reservoir
fluids.
– gas vs. oil
– primary recovery vs. secondary recovery
– royalty leases vs. production sharing contracts??
• These may prevent agreement on “terms of
trade” by which individual holdings are
exchanged for shares of the unitized field.

How Many “Participating Areas” in the Unit?
• Dual “Participating Areas” are created to help
owners reach agreement on equity shares.

How Many “Participating Areas” in the Unit?
• Dual “Participating Areas” are created to help
owners reach agreement on equity shares.
• Common Examples
– “Oil Rim vs. “Gas Cap” participating areas
– “Primary” vs. “Secondary” participating areas

• Dual “Participating Areas” are created to help

• Common Examples
– “Oil Rim vs. “Gas Cap” participating areas

• Intended benefit: to circumvent conflict over the

Negative Impact of Dual Participating Areas
• Creates competition among owners.
• Imposes conflicting perspectives on a shared

Negative Impact of Dual Participating Areas
• Creates competition among owners.
• Imposes conflicting perspectives on a shared
investment problem.
• Exposes owners to the “hold up” problem: pressure
to alter agreements after costs have been sunk and
bargaining leverage lost.

• Creates competition among owners.
• Imposes conflicting perspectives on a shared

• Only postpones hard decisions, and may increase
the cost of reaching ultimate agreement.

two regimes. (probably not)

– There is uncertainty re: the fiscal burden that each regime
will impose on affected production streams. (maybe, if

Ex. 3: Divergent Fiscal Regimes ??
• Question: Can royalty and production-sharing leases be
combined (voluntarily) into one unit?
• Answer: It depends; problems arise only if:
– There is uncertainty re: specific terms or application of the
two regimes. (probably not)
– There is uncertainty re: the fiscal burden that each regime
will impose on affected production streams. (maybe, if
variations in future oil prices influence the R-factor)
– That uncertainty fosters disagreement among owners re:
future fiscal burdens under the two regimes. (don’t know,
but this is conceivable)

• In confronting this question, Brazil is on a new frontier in the
development and adaptation of unitization schemes to an
imperfect world.
