REPORT AND RECOMMENDATION Before the undersigned Magistrate Judge, on reference from the District Court, is a Rule 12(b)(6) motion to dismiss for failure to state a claim upon which relief can be granted or, in the alternative, motion for more definite statement [doc. # 39] filed by Defendant, NGS Sub Corp. (“NGS”). The motion is opposed. For reasons explained below, IT IS RECOMMENDED that the motion to dismiss be GRANTED IN PART and DENIED IN PART. IT IS FURTHER ORDERED that the motion for more definite statement is DENIED. Background On October 2, 2025, Plaintiff Myrt Hales (“Hales”)1 filed the instant oilfield

1 Hales appears herein and seeks recovery in one or more of the following capacities: (1) Lessor, assignee, or third-party beneficiary of certain mineral and/or surface leases between Plaintiff and Defendants; (2) successor in interest to certain mineral and/or surface leases between Plaintiff and Defendants; (3) owner of property contaminated by the oil and gas activities conducted or controlled by one or more of the Defendants; (4) successor in interest to, or the assignee of, the owners of Property contaminated by the oil and gas activities conducted or controlled by one or more of the Defendants; (5) servitude owner who has the right to sue for remediation damages under the Mineral Code; and (6) parties who possess the right of action to file this lawsuit under Louisiana law. (Petition, ¶ 3). contamination a/k/a “legacy” lawsuit2 in the Fifth Judicial District Court for the Parish of Richland, State of Louisiana, against ten Defendants,3 arising out of decades-long oil and gas exploration and production activities conducted on Hales’ property by the Defendants and/or their predecessors. (Petition).4 Specifically, Hales alleged that he owns and/or uses certain property in Richland Parish that Defendants or their predecessors-in-interest contaminated or otherwise damaged via their oil and gas exploration and production activities, which included the construction, and subsequent abandonment of wells, sumps, flowlines, pipelines, tank batteries, wellheads, unlined earthen pits, measuring facilities, barges, production platforms, separators, and injection facilities. (Petition, ¶¶ 5-6). Hales asserted a comprehensive array of theories of

recovery against Defendants and seeks to recover compensatory, punitive, and/or exemplary damages associated with restoring the lands to their original, unpolluted state, the diminution of property value, and resulting stigma. (Petition, Prayer). He also requested injunctive and equitable relief, plus an award of attorney’s fees. Id. On November 14, 2025, Defendants, Anadarko US Offshore, LLC (“Anadarko”) and

2 “These types of actions are known as ‘legacy litigation’ because they often arise from operations conducted many decades ago, leaving an unwanted ‘legacy’ in the form of actual or alleged contamination.” Marin v. Exxon Mobil Corp., 48 So.3d 234, 239 n.1 (La. 2010) (citation omitted).

3 They include: Kerr-McGee Oil & Gas Onshore LP; Anadarko US Offshore, L.L.C.; Occidental Petroleum Corporation; Hess Corporation; Williams Well Service, Inc.; NGS; Ashley Investment Company; Murphy Oil Corporation; Murphy Exploration & Production Company; and Murphy Exploration & Production Company – USA. (Petition, ¶ 4).

4 Several documents are attached to the Petition, including an aerial photo map of the property showing well locations; an “Operator History” that lists the operators of the wells at issue and dates of operations; photographs of certain wells and equipment on the Property; a “Lease Abstract” that lists known mineral leases and other agreements that affect the property; and a letter sent to the Commissioner of Conservation. See Petition, ¶ 7 (explaining and incorporating the attached Exhibits A-E). 2 Kerr-McGee Oil & Gas Onshore LP (“KMOGO”), removed the suit to federal court on the sole basis of diversity jurisdiction, 28 U.S.C. § 1332. (Joint Notice of Removal [doc. # 1]). Anadarko and KMOGO established that Hales’ citizenship is completely diverse from all properly joined Defendants5 and that the amount in controversy exceeded $75,000 at the time of removal. See Notice of Removal. On January 15, 2026, Defendant, Hess Corporation, filed a Rule 12(b)(6) motion, which it combined with a Rule 12(e) motion for more definite statement. [doc. # 33]. On that same day, Defendants, Anadarko and KMOGO, also filed a Rule 12(b)(6) motion. [doc. # 36]. On January 15, 2026, Defendant, NGS, also filed the instant Rule 12(b)(6) motion

together with an alternative Rule 12(e) motion for more definite statement. [doc. # 39]. NGS asserted that Hales’ Petition failed to include any factual allegations against it, and, therefore, NGS should be dismissed from the case entirely. Alternatively, NGS argued that nine specific claims or theories of recovery should be dismissed: 1) liability under Louisiana Civil Code article 2688; (2) punitive and/or exemplary damages under former Civil Code article 2315.3; (3) strict liability under pre- and post-1996 versions of Civil Code article 667; (4) liability under pre- and post-1996 versions of Civil Code articles 2317 and 2322; (5) breach of contract; (6) civil fruits; (7) loss of enjoyment and use of property, land loss and subsidence; (8) unjust enrichment; and (9) fraud.

(M/Dismiss, Memo., pg. 7).

On February 9, 2026, the Court signed a Stipulation and Consent Judgment that resolved

5 By all accounts, Defendant, Williams Well Service, Inc. (“WWS”), shared common citizenship with Hales. (Notice of Removal). However, Anadarko and KMOGO submitted evidence to show that Hales had no reasonable possibility of recovery against WWS, and, thus, its citizenship should be disregarded for the purpose of diversity jurisdiction. Id., Exh. 4. Hales effectively conceded as much because, on December 23, 2025, the Court granted his motion to voluntarily dismiss WWS from the suit. [doc. #s 28 & 30].

3 the motions to dismiss and/or for more definite statement [doc. #s 33 & 36] filed by Defendants, Hess Corporation, Andarko, and KMOGO. [doc. # 47]. On February 13, 2026, Hales filed his opposition to NGS’s combined Rule 12(b)(6) and Rule 12(e) motion. (Pl. Opp. [doc. # 51]). On February 20, 2026, NGS filed its reply brief. (NGS Reply [doc. # 54]). On March 10, 2026, the Court entered a Consent Judgment between Hales and NGS that resolved many of the issues raised by NGS’s pending motion(s). (Joint M/Entry of Consent Judgment [doc. # 60] and Consent Judgment [doc. # 62]. The matter is ripe.

Analysis6 In their joint motion for entry of consent motion, the parties agreed that, upon entry of the Consent Judgment, only three issues would remain for the Court to decide: • Liability under Louisiana Civil Code article 2688; • Liability under pre-and post-1996 versions of Civil Code articles 2317 & 2322;
