Explanatory Note: This Amendment No. 4 amends and supplements the Statement on Schedule 13D (the “Initial Statement”) filed by the reporting persons named in Item 2 thereof (the “Reporting Persons”) on March 1, 2013, as amended on May 22, 2013, as amended on October 17, 2013 and further amended on May 16, 2104, relating to the shares of common stock, par value $0.001 (the “Common Shares”), of Emerald Oil, Inc., a Montana corporation (the “Issuer”).

Capitalized terms used in this Amendment and not otherwise defined shall have the same meanings ascribed to them in the Initial Statement.

Item 1. Security and Issuer.

Item 1 of the Initial Statement is hereby amended and replaced with the following:

The principal executive offices of the Issuer are located at 1600 Broadway, Suite 1040, Denver, CO 80202. The total number of Common Shares reported as beneficially owned in this Schedule 13D is 21,921,309 which constitutes approximately 32.91% of the total number of Common Shares outstanding on a pro forma basis. The beneficial ownership reported in this Schedule 13D reflects that at February 11, 2015 there would have been 66,619,355 Common Shares outstanding after giving pro forma effect to the issuance to the Reporting Persons of Common Shares as described herein. The Reporting Persons beneficially own 21,921,309 Common Shares and 5,114,633 Common Shares, which are issuable upon exercise of warrants (the “Warrants”) that the Reporting Persons acquired on February 11, 2013.

Each Warrant is coupled, and traded as a unit, with a number of Series B Shares (as defined below) equal to the number of Common Shares purchasable upon exercise of the Warrant. The Warrants and the Series B Shares (as such term is defined below) may not be transferred separately. If and when the Warrant is exercised, the holder of the Warrant will be required to deliver to the Issuer, as part of the payment of the exercise price, a number of Series B Shares equal to the number of shares of Common Shares purchased upon such exercise. The holders of Series B Shares will be entitled to vote in the election of directors and on all other matters submitted to a vote of the holders of Common Shares, with the holders of Series B Shares and the holders of Common Shares voting together as a single class. Each share of Series B Shares will have one vote.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Initial Statement is hereby amended and replaced with the following:

(1)-(2)	(i)	WD Investor I is deemed to have beneficial ownership of 21,188,814 Common Shares and currently has beneficial ownership of one Warrant entitling WD Investor I to purchase up to 4,943,729 Common Shares, which in the aggregate (and after the Warrants have been exercised) equals a beneficial ownership of 26,132,543 Common Shares (approximately 31.08%).
	(ii)	WD Investor II is deemed to have beneficial ownership of 732,495 Common Shares and currently has beneficial ownership of one Warrant entitling WD Investor II to purchase up to 170,904 Common Shares, which in the aggregate (and after the Warrants have been exercised) equals a beneficial ownership of 903,399 Common Shares (approximately 1.07%).
	(iii)	White Deer Energy L.P., a Cayman Islands exempted limited partnership (“White Deer”), does not directly own any Common Shares. By virtue of being a member of WD Investor I, White Deer may be deemed to possess voting and dispositive power with respect to 25,293,237.65 Common Shares (after the Warrants held by WD Investor I, which White Deer has a beneficial ownership in, have been exercised) (approximately 30.08%).
	(iv)	White Deer TE L.P., a Cayman Islands exempted limited partnership (“White Deer TE” and, collectively with White Deer and WD Investor II, the “White Deer Funds”) does not directly own any Common Shares. By virtue of being a member of WD Investor I, White Deer TE may be deemed to possess voting and dispositive power with respect to 839,305.35 Common Shares (after the Warrants held by WD Investor I, which White Deer TE has a beneficial ownership in, have been exercised) (approximately 1.00%).

(Page 8 of 11 Pages)

	(v)	Edelman & Guill Energy L.P., a Cayman Islands exempted limited partnership (“GP LP”) does not directly own any Common Shares. By virtue of being the general partner of the White Deer Funds, GP LP may be deemed to possess sole voting and dispositive power with respect to the aggregate 27,035,942 Common Shares (after the Warrants, which GP LP has a beneficial ownership in, have been exercised) (approximately 32.16%).
	(vi)	Edelman & Guill Energy Ltd., a Cayman Islands corporation (“GP Ltd.”) does not directly own any Shares. By virtue of being the general partner of the GP LP, GP Ltd. may be deemed to possess shared voting and dispositive power with respect to the aggregate 27,035,942 Common (after the Warrants, which GP Ltd. has a beneficial ownership in, have been exercised) (approximately 32.16%).
(a)	Other than as described in Item 3, none.
(b)	None.
(c)	Not applicable.
