Charles W Brown and Patty N Brown LLC v. Newfield Exploration Mid-Continent Inc, 5:19-cv-00600

Plaintiffs Charles W. Brown and Patty N. Brown, LLC own mineral interests in Section 19, Stephens County, Oklahoma, leased to Heritage Resources – NonOp, LLC; lease entitles Plaintiffs to a 1/4 royalty of gross proceeds free of costs except taxes.
Defendant Newfield operated multiple horizontal wells in Section 19; initially paid no royalties, then paid after identifying Plaintiffs as 1/8 instead of 1/4; Plaintiffs allege Defendant failed to include PRSA interest for late payments (PRSA-related matters later resolved between parties).
Plaintiffs filed suit (removed to federal court) asserting breach of contract, negligence, unjust enrichment, PRSA violations, and underpayment based on improper cost deductions; Defendant moved to dismiss several claims.
Plaintiffs do not allege Newfield signed the Lease Agreements or that there was a written assignment; Plaintiffs contend Newfield, as operator of record, assumed the lease obligations.
Plaintiffs’ pleadings lacked factual detail identifying (a) any assignment or assumption of the lease to Newfield and (b) which costs were allegedly wrongfully deducted from royalties.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Plaintiffs stated a breach-of-contract claim against Newfield, a non-signatory	Newfield was operator of record and thereby agreed to or assumed obligations under Plaintiffs' lease with Heritage	No contract exists between Plaintiffs and Newfield; Plaintiffs failed to identify an assignment or written basis making Newfield party to the lease	Claim dismissed without prejudice for failure to plausibly allege a contractual relationship or assignment
Whether Plaintiffs plausibly alleged underpayment of royalties based on improper cost deductions	Royalty should be 1/4 of gross production free of cost deductions; Newfield deducted unspecified costs	Pleading merely alleges „costs" were deducted without identifying which costs or facts; claim sounds in contract, which Plaintiffs have not alleged with Newfield	Claim dismissed without prejudice as conclusory and insufficient under Twombly/Iqbal; and contract-based claim fails given absence of contractual relationship
Whether Plaintiffs may amend the complaint	Plaintiffs request leave to amend if dismissal granted	Defendant opposed or relied on local rules for amendment procedure	Request denied without prejudice for noncompliance with Local Civil Rule 15.1; court permitted a compliant motion to amend by March 31, 2021, to be evaluated for futility and prior failures
