26 USC 45I - Credit for producing oil and gas from marginal wells

(a) General rule 
For purposes of section 38, the marginal well production credit for any taxable year is an amount equal to the product of
(1) the credit amount, and
(2) the qualified crude oil production and the qualified natural gas production which is attributable to the taxpayer.
(b) Credit amount 
For purposes of this section

view counter
(1) In general 
The credit amount is
(A) $3 per barrel of qualified crude oil production, and
(B) 50 cents per 1,000 cubic feet of qualified natural gas production.
(2) Reduction as oil and gas prices increase 

(A) In general 
The $3 and 50 cents amounts under paragraph (1) shall each be reduced (but not below zero) by an amount which bears the same ratio to such amount (determined without regard to this paragraph) as
(i) the excess (if any) of the applicable reference price over $15 ($1.67 for qualified natural gas production), bears to
(ii) $3 ($0.33 for qualified natural gas production).

The applicable reference price for a taxable year is the reference price of the calendar year preceding the calendar year in which the taxable year begins.

(B) Inflation adjustment 
In the case of any taxable year beginning in a calendar year after 2005, each of the dollar amounts contained in subparagraph (A) shall be increased to an amount equal to such dollar amount multiplied by the inflation adjustment factor for such calendar year (determined under section 43 (b)(3)(B) by substituting 2004 for 1990).
(C) Reference price 
For purposes of this paragraph, the term reference price means, with respect to any calendar year
(i) in the case of qualified crude oil production, the reference price determined under section 45K (d)(2)(C), and

(ii) in the case of qualified natural gas production, the Secretarys estimate of the annual average wellhead price per 1,000 cubic feet for all domestic natural gas.
(c) Qualified crude oil and natural gas production 
For purposes of this section
(1) In general 
The terms qualified crude oil production and qualified natural gas production mean domestic crude oil or natural gas which is produced from a qualified marginal well.
(2) Limitation on amount of production which may qualify 

(A) In general 
Crude oil or natural gas produced during any taxable year from any well shall not be treated as qualified crude oil production or qualified natural gas production to the extent production from the well during the taxable year exceeds 1,095 barrels or barrel-of-oil equivalents (as defined in section 45K (d)(5)).
(B) Proportionate reductions 

(i) Short taxable years In the case of a short taxable year, the limitations under this paragraph shall be proportionately reduced to reflect the ratio which the number of days in such taxable year bears to 365.
(ii) Wells not in production entire year In the case of a well which is not capable of production during each day of a taxable year, the limitations under this paragraph applicable to the well shall be proportionately reduced to reflect the ratio which the number of days of production bears to the total number of days in the taxable year.
(3) Definitions 

(A) Qualified marginal well 
The term qualified marginal well means a domestic well
(i) the production from which during the taxable year is treated as marginal production under section 613A (c)(6), or
(ii) which, during the taxable year
(I) has average daily production of not more than 25 barrel-of-oil equivalents (as so defined), and
(II) produces water at a rate not less than 95 percent of total well effluent.
(B) Crude oil, etc. 
The terms crude oil, natural gas, domestic, and barrel have the meanings given such terms by section 613A (e).
(d) Other rules 

(1) Production attributable to the taxpayer 
In the case of a qualified marginal well in which there is more than one owner of operating interests in the well and the crude oil or natural gas production exceeds the limitation under subsection (c)(2), qualifying crude oil production or qualifying natural gas production attributable to the taxpayer shall be determined on the basis of the ratio which taxpayers revenue interest in the production bears to the aggregate of the revenue interests of all operating interest owners in the production.
(2) Operating interest required 
Any credit under this section may be claimed only on production which is attributable to the holder of an operating interest.
(3) Production from nonconventional sources excluded 
In the case of production from a qualified marginal well which is eligible for the credit allowed under section 45K for the taxable year, no credit shall be allowable under this section unless the taxpayer elects not to claim the credit under section 45K with respect to the well.
