1 OIL & GAS DEVELOPMENT AND UNITIZATION LAWS IN VARIOUS STATES MARCH 2010

2 INTRODUCTION RULE OF CAPTURE VS CORRELATIVE RIGHTS

3 RULE OF CAPTURE LANDOWNER MAY PRODUCE OIL & GAS UNDER HIS PROPERTY WITHOUT REGARD WHETHER HE DRAINS HIS NEIGHBORS PROPERTY AS WELL NO LEGAL LIABILITY UNLESS WASTE RESOURCE OR DAMAGE RESERVOIR

4 CORRELATIVE RIGHTS EACH OWNER IN A COMMON OIL AND GAS POOL IS AFFORDED AN OPPORTUNITY TO RECOVER HIS JUST & EQUITABLE SHARE OF RESERVES GOAL IS TO LIMIT UNCOMPENSATED DRAINAGE, BUT NOT AN ABSOLUTE RIGHT – MUST EXERCISE RIGHT TO DRILL TO CLAIM CORRELATIVE RIGHT

5 PETROLEUM GEOLOGY, MINERAL INTERESTS AND REGULATION

6 PETROLEUM TRAP ELEMENTS PETROLEUM SOURCE ROCK MIGRATIONAL PATHWAY POROUS FORMATION ROCK SEALING IMPERMEABLE CAPROCK OR BED

13 JURISDICTION OF CONSERVATION AGENCIES TO REGULATE OIL AND GAS DEVELOPMENT

14 COMMON OIL AND GAS REGULATORY TERMS MEANING OF POOL FOR REGULATORY PURPOSES Underground reservoir containing an interconnected common accumulation of crude oil and/or natural gas in pressure communication

15 COMMON OIL AND GAS REGULATORY TERMS CONCEPT OF A DRILLING UNIT Maximum area from which one well can efficiently and economically drain the recoverable oil and gas reserves in a given reservoir

18 EFFECT OF UNITIZATION ON MINERAL RIGHTS CREATES A LEGAL FICTION THAT OPERATIONS OR PRODUCTION ANYWHERE ON THE UNIT IS AS IF ON EACH AND EVERY LEASE IN THE UNIT NOT A CROSS ASSIGNMENT – EACH LESSEE STILL OWNS AND REMAINS RESPONSIBLE TO HIS OWN LESSOR MUST BE UNIT OPERNS OR PRODN

19 COMPARISON OF OIL AND GAS DEVELOPMENT REGULATORY STRUCTURES IN FIVE STATES

20 OKLAHOMA WELL SPACING AND POOLING LAW CREATE DRILLING & SPACING UNITS LOCATION EXCEPTIONS INCREASED DENSITY WELLS FORCED POOLINGS

21 OKLAHOMA WELL SPACING GENERAL STATEWIDE RULE

22

23 OKLAHOMA WELL SPACING DRILLING AND SPACING UNITS

24 DRILLING & SPACING UNIT GENERAL REQUIREMENTS APPROXIMATELY SQUARE OR RECTANGULAR AND USUALLY OF UNIFORM SIZE ACROSS SAME POOL COMBINATION RESERVOIRS MAY HAVE NON-UNIFORM SIZE UNITS < 40 ACRES FOR OIL WELLS < 4,000 < 80 ACRES FOR OIL WELLS BETWEEN 4,000 AND 9,990

25 OFF-CENTER S/BACREAGE SIZE or or or 320 1, OKLAHOMA OFF-CENTER SETBACK / ACREAGE SIZE RULE FOR SPACING UNITS

26

27 DRILLING & SPACING UNIT GENERAL REQUIREMENTS > 160 ACRE UNIT HOLDS LEASE ACREAGE OUTSIDE OF UNIT FOR ONLY 90 DAYS AFTER END OF TERM TOTAL UNIT ACRES LIMITED TO 640 ACRES WITH 10% TOLERANCE NO REQUIREMENT UNIT BE SHOWN UNDERLAIN ENTIRELY BY PAY FOR FULL ALLOWABLE

28 OKLAHOMA LOCATION EXCEPTION

29

30 OKLAHOMA INCREASED DENSITY WELL

31

32 OKLAHOMA FORCED POOLING IN DRILLING AND SPACING UNITS

33

34

35 OKLAHOMA FIELD-WIDE POOLING

36

37 KANSAS WELL SPACING AND FIELD-WIDE POOLING LAW General Spacing and Oil Unit Rules Well Spacing and Basic Proration Orders –UNIT ACREAGE TO BE SHOWN REASONABLY PRODUCTIVE Location Exceptions -- YES NO General Compulsory Pooling Law Field-wide Pooling - YES

38

39 KANSAS BASIC PRORATION ORDER MODEL

40 LOCATION EXCEPTIONS METHODS STANDARD ADMINISTRATIVE APPLICATION BPO SLIDING SCALE WITHOUT APPLICATION BPO STANDARD GAS WELL SETBACK -> 1250 WELL LOCATION TO W/IN 330 OF UNIT LINE DIVIDE DISTANCE FROM LINE BY 1250, THEN MULTIPLY QUOTIENT BY INITIAL RATE TO DETERMINE PENALTY ON PRODUCTION SUBJECT TO STATEWIDE OVERAGE RULE

41 LOCATION EXCEPTION METHODS

42 ALTERNATE TRACT UNITS Novel feature of large gas field BPOs in Kansas - ATUs Combine adjoining tracts from existing units to form new 640-acre ATU – either 4 X 160 acres or 2 X 320 acres One ATU well drilled as near center of ATU as practical Existing units contributing tracts share in ATU production Does not affect allocation from unit wells in existing units Effort to drill in corners and along boundary lines not drained by existing production Fairer to competing interests than standard location exceptions

43 ALTERNATE TRACT UNIT (4 X 160 ACRES)

44 ALTERNATE TRACT UNIT (2 X 320 ACRES)

45 LOUISIANA WELL SPACING AND POOLING LAW Unitization – Drilling and Production Units Field-wide (Reservoirwide) Units Unitization and Equity among Unit Interests Well Spacing Limited Location Exceptions Replacement (Substitute Unit) Wells Increased Density (Alternate Unit) Wells

46

47

48 LOUISIANA GENERAL SPACING RULE

49

50 TEXAS WELL SPACING AND POOLING LAW Well Spacing and Density (Acreage Requirement) Compulsory Pooling in Texas -- Rare Voluntary Field-wide Unitization Statute w/o Compulsory Pooling Provision by Vote or Otherwise

51 SPACING RULE (From Line- Apart) ACREAGE REQUIREMENT 150 – – – – – – – TEXAS GENERAL SETBACK / ACREAGE SIZE RULE

52 Texas Compulsory Pooling Voluntary pooling strongly favored Forced pooling only after voluntary efforts prove futile and several prerequisites met Only allowed ~100 times since 1965 Limited to < 160-acre oil units / < 640-acre gas units Voluntary unitization statute for EOR or gas recycling has no compulsory clause

53

54 COLORADO WELL SPACING & POOLING LAW Well Spacing – > 2500 deep: 600 from lease line / 1200 from well in same pool; <2500 deep: 200 from line / 300 apart Drilling Units by Order – drained by 1 well Location Exception – waiver>variance>hrg Density Drilling – no set unit size / area Forced Pooling and Field-wide Unitization

55

56 NOTICE REQUIREMENTS DIFFER FROM STATE TO STATE - TIME PERSONAL NOTICE TO INTERESTED PARTIES AND PUBLICATION NOTICE VIA NEWSPAPERS IN COUNTIES OF AGENCY AND LAND AT ISSUE MULANE STANDARD ESSENTIAL FOR CONSTITUTIONAL SUFFICIENCY AS TO OPPORTUNITY TO APPEAR & HRG

57 NOTICE REQUIREMENTS MULANE STANDARD – THAT NOTICE REASONABLE UNDER THE CIRCUMSTANCES CALCULATED TO APPRISE A PROPERTY OWNER OF HIS RIGHT TO APPEAR AND BE HEARD AS TO POTENTIAL ADVERSE LEGAL EFFECT ON HIS PROPERY RIGHTS AS A MATTER OF DUE PROCESS
