Oil & Gas Flashcards
(53 cards)
Hydrocarbons are found deposited in two types of sub-surface reservoirs of sedimentary rock. Describe each type.
Describe the two ways these reservoirs are drilled.
How is porosity and permeability involved. Define.
Gas Driven reservoir: gas on top and oil underneath; as you drill oil the gas heats up, expanding to push oil up.
Water Driven Expansion reservoir: oil on top and water below; water will push oil up.
Conventional: hydrocarbons trapped within this type generally have good porosity and permeability.
Non-Conventional (shale): here, the strata layer will have porosity, but use of hydraulic fracturing (water/sand) is implemented to allow hydrocarbons to flow out of strata; fracturing improves permeability by blasting away the muck.
Porosity: ratio of air voids within a given sample strata material; ability of a rock to hold the hydrocarbon molecules; think sponge (absorbs)
Permeability: ability of either the fluid or gas to flow through the rock
Why is it important sub-surface formation to be both porous and permeable.
How does down hole pressure effect these two parameters.
Allows hydrocarbon molecules to flow to a point of low pressure. Always, these fluids and gas are under high pressure and by nature fugacious, thus once the cap is tapped they move up the drill pipe to the surface.
When the drilling pipe enters it provides a great escape for the gas or fluid cap in the sub-surface. The higher this pressure the more gas or fluid that is captured. However, if you tap the cap too much then this pressure can be lost.
Private Real Property Ownership - Ad Colemn theory
states you have right to the land from the depths to the skies
Rule of Capture.
Why do we use this.
Who does it reward.
Downside.
Modified
may draw without liability from a common pool of gas or fluid so long as you do so on your land; may also artificial enhance production.
Use: may be lack of technology;
Rewards those with diligence, spending $, & taking the risk;
Downside is excess drilling, physical waste, & economic waste; expenses are passed onto consumer
modified by prorationing and well spacing
TX & OK: Ownership of O/G
TX: Caporal possessory interest with exception where it could be lost under rule of capture; ownership in place; right to partition; right to ejectment; can adversely possess a severed mineral interest; can’t be abandoned
OK: Incorporeal interest; exclusive right to take; no right to partition or ejectment; get easement by prescription; can be abandoned
Correlative Rights Doctrine
Elliff v Texon set forth:
Fair Share Principle
protects owners from negligent or wasteful operations that injure or destroy the common source of supply; wells on different tracts of land have communication; same bottom hole pressure then communication
ownership in place, qualified by rule of capture but subject to correlative rights doctrine
entitled to fair opportunity to produce your fair share of reservoir; fair share is proportion of O/G under your tract
-can’t produce more than the well will allow
Conservative Acts towards production
created administrative agencies;
now must have permit to drill a well;
well spacing for one well to economically and efficiently drain its area; divides into units;
prorationing by regulating the rate of production;
file well logs with agency;
Trespass
Conversion
O&G: Real v. Personal Property
force or pressure or entry on someone else’s real property; measured in diminution in FMV
person exercises dominion and control over another person personal property to the point they should have to buy it
Real: when in place within the subsurface
Personal: severed at the well head
Non-Participating Royalty Interest (NPRI)
right to royalty created by grant or reservation in deed and is separation of the royalty interest from the mineral estate
- has no executive right
- there’s no easement to explore for or produce
- share of production after extraction
- cost free of production
Generally: you may have an 1/4 royalty interest but have a 1/16 lease royalty interest because the oil co. only gives you 1/4 lease royalty interest, thus 1/4*1/4=1/16.
Mineral Estate
conveys the minerals in place; core is the development right accompanied by executive right entitles a person to a right of bonus, delay rental payments, and royalty; reads: “IN AND UNDER”
Development Right: allows for holder to explore for and produce the oil and gas, includes an implied easement of (reasonable) surface usage (to explore for and produce minerals)
Executive Right: to execute the O/G lease bonus: cash paid up front for execution of lease
delay rental payments: development delayed then right to receive payments
royalty: cost free share of production
Ways to sever Mineral Estate from Surface Estate
Sever by deed: mineral deed
Sever by Reservation: grantor conveys away the surface while reserving the mineral estate
In deed, reservation, or severance can be by strata (depth) or substance (oil, gas, coal)
Describe Royalty
Types.
mineral owner’s right to factional share of production (1/8)
Landowner R: share of production paid to owner of mineral estate as compensation for O&G lease
NPRI: right created by grant or reservation in deed and separation of royalty interest from mineral estate; no executive right, no easement to explore for or produce, share of production after extraction, cost free of production
Working Interest: lessee’s operating agreement; right to use surface, incur costs, retain profits
Overriding Roy. Int.: cost free interest that burdens working interest
Net Profits Interest: when well gets a net profit then person is entitled to percentage
Two classifications of Royalty.
Describe.
Straight Fractional Share: share of gross production; Lease: 1/8R then you have 1/8R
Fractional Share of: mineral estate, cost bearing production or cost free production; Lease: 1/8R but FS of 1/8R then 1/64
Mineral Ownership or Royalty Ownership?
Within the wording of a grant or reservation, distinguish between “in and under” and “saved and produced.”
in and under: indicative of a mineral estate because referencing the minerals in place
saved and produced: indicative of NPRI because denotes share of production after extraction
Distinguish between Mineral Estate & NPRI.
Mineral Estate
• cost bearing
• development right
o includes the executive and implied surface easement
o mineral owner shares in proportionate share of bonus and delay rentals
• minerals in situ; in place in the subsurface
• language descriptive of it; indicia of intent: “in and under”
NPRI
• cost-free
• cannot explore for or produce
• may have implied easement to ensure produce is accounting properly for royalty
• doesn’t share in bonus or delay rental payments
• share after extraction
• language is “produced and saved”
Plain Meaning/Ambiguous:
Consider the surrounding circumstances with their use; mineral
words with well understood meanings within in the industry: Minerals, Royalty, Bonus, Rentals, Executory Interest
OK mineral: when you have an oil and gas lease in existence and the granting clause is as to a fraction of royalty; oil and gas lease in existence, it’s probably a royalty interest; no lease in existence, it’s probably a mineral estate
TX mineral: look at the intention of the granting clause and language: grants royalty but strips of bonus, rentals, or executive interest then TX says its a mineral estate which severed the above mentioned, thus a royalty interest to a mineral estate.
Concurrent Ownership.
How does it apply with respect to rights of co-tenants relating to development and production.
Developing Co-t accounting duties
Accounting: per well or per tract of land
must share % of proceeds & rents; negligently producing (waste) is a reason for another co-tenant to intervene and collect damages.
Development: allows any co-t, regardless of their interest, to explore for and produce minerals w/o permission of the other co-t
non-consenting co-tenant is not entitled to damages for waste, but the developing co-tenant must account to non-consenting co-tenant if the well is productive
Co-t accounting duties: you receive rents or profits from third parties; you have to account to your co-tenants for their proportionate share.
Net-profits accounting: means co-tenant doesn’t have to account until there’s a profit
Developing co-t is cost bearing at to the non. consenting co-t share; carried interest: bears the risk/cost of non. consent co-t; thus marginal well then non. consenting co-t does not have to pay
Accounting: per well of barrels produced or mcf
How to prevent carried interest.
prevent by negotiating a lease with a (proportional reduction clause)
use of AR receivership statute; take to ct. and have O/G submit bids and court will give everyone their proportionate share (ct. like an implied agency)
forced integration: compulsory pooling
ratification: non. consent co-t can ratify then get cost free royalty rather than net profits
Tenancy in Common
Joint Tenancy
Tenancy by the Entirety
Partition; Equitable defenses.
TIC: passive co-t gets proportionate share after costs recovered; entitled to royalty share; may perform a Joint Operating Agreement: K with 3p as to who operate the well and proportionate shares of cost & revenue
JT: contains right of survivorship; non-testamentary; 4 essential unities: Possession Intent Time Title; severance destroys unity and thus becomes TIC
Tenancy By Entirety: PITT contains right of suiviorship; non-testamentary; 5 essential unities: PITT plus marriage; severance destroys unity and thus becomes TIC ;
Partition by kind: equal division
Partition by sale: judicial sale
Def.: fraud, unable to buy at sale, or no disagreement with development
What cost can a developing co-t deduct from non-cons. co-t?
Called “Setoff cost.” Must be reasonable costs and had to confer a benefit
i.e. drilling of a dry hole led to drilling of another producing well then % non-cons. interest may be deducted
Present and Future interest: Successive Ownership: Life Estate and the Remainder.
Lease & Production.
Division of benefits:
Possession, bonus, delay rentals, royalty
Problems with LT receiving royalties.
How a present division of Royalty effects the LT and R.
Life estate has present interest & upon LE death will vest to remaindermen who take possession which the property must be in a substantially identical state as was at inception of LE; exclusive right to possession; entitled to incomes.
Remaindermen: corpus; upfront payment for minerals
L&P: need consent of both parties; contract must have substantially identical terms; to act without consent of future interest would be waste and dissipation of corpus, thus a damage.
Division:
LE: entitled to exclusive possession and income from any payments that represent the corpus; only entitled to income from payments from the corpus
Bonus is income in OK and corpus TX.
Delay Rentals are income from corpus
Royalty are corpus, thus goes to some fund with a trustee
Problems are LT receives royalty payments and then has an obligation to invest wisely. The solution is to setup a trust that can draw interest.
Effect: this allows everyone to get paid now! Take into account LT age, health, etc. and set up a scale of % royalty; value the LE and R interest and divide the proceeds accordingly.
Solution: do not set a LE and R in mineral interest; simply, setup a trust.
Open Mines Doctrine
OMD: if a mine is open when the life estate is created, the life tenant gets all royalty
Applies if testator leased the minerals to someone before the life estate was executed
Does not apply if testator’s lease expires w/o drilling and the LE tries to execute a new lease
Uniform Principal and Income Act (UPIA)
sets out a definitive percentage of what is income and what is corpus, and life of the life tenant is not a factor, which will become the default if a division or split is not specified
a) used when you don’t specify the division btw the life tenant and remainder, as for the bonus, delay rental payments, and royalty; 1997 amended act; 90% corpus, 10% income
How does a contingent remainder change how the Oil Co. gets a lease from LT & Rc.
LL/T
Easements
Mortgages
Can go out and merge the K’s between the two, but must utilize the contingent remaindemen statute
LL/T: T no executive right to explore for or produce minerals because waste; holder of estate has exclusive right to possession; O/G lessee can drill if K before T lease; in estate for years there is an implied easement for minerals (*)
Easements: lessee can’t engage in surface activities tha tun duly interfere with or burden the easement
Mortgages: mortgagee has right to possession prior to default; cannot commit waste so long as Me does not reduce property value; Mo usually gets revenue from production
