IN RE EOG RESOURCES, INC. RELATOR

ORIGINAL PROCEEDING

MEMORANDUM OPINION1

----------

Relator EOG Resources, Inc. filed this petition for writ of mandamus 

seeking to vacate the trial court’s order requiring it to produce privileged trade 

secret information during pretrial discovery.

David and Shelly Richey sued EOG alleging that after they had entered 

into an oil and gas lease with EOG, it improperly failed to include their land in a 

pooled unit with similarly-located leases and that EOG improperly drained oil and 

gas from underneath their property. In discovery, the Richeys sought EOG’s

geologic and seismic data for their property and any property located within one 

mile of their property. EOG objected to the Richeys’ request for production 

claiming, among other things, that the information sought is “confidential, 

business, and/or proprietary information.” The Richeys moved to compel 

production of the information, and the trial court held an evidentiary hearing.

At the hearing, the parties stipulated that the information sought is 

privileged trade secret information. Following the hearing, the trial court signed 

an order compelling production of the information to the Richeys. In its order, the 

trial court found that the Richeys had met their burden to show that the trade 

secret information sought in their request for production is necessary for a fair 

adjudication of their claims. EOG then filed a petition for writ of mandamus in 

this court challenging the trial court’s order.

Texas Rule of Evidence 507 provides,

A person has a privilege, which may be claimed by the person 

or the person’s agent or employee, to refuse to disclose and to 

prevent other persons from disclosing a trade secret owned by the 

person, if the allowance of the privilege will not tend to conceal fraud 

or otherwise work injustice. When disclosure is directed, the judge 

shall take such protective measure as the interests of the holder of 

the privilege and of the parties and the furtherance of justice may 

require.

Tex. R. Evid. 507. After a party resisting discovery establishes that the 

information is a trade secret, the burden shifts to the requesting party to establish 

that the information is necessary for a fair adjudication of its claims. E.g., In re 

Cont’l Gen. Tire, Inc., 979 S.W.2d 609, 613 (Tex. 1998) (orig. proceeding). “[A]

party seeking such information cannot merely assert unfairness but must 

demonstrate with specificity exactly how the lack of the information will impair the 

presentation of the case on the merits to the point that an unjust result is a real, 

rather than a merely possible, threat.” In re Bridgestone/Firestone, Inc., 106 

S.W.3d 730, 733 (Tex. 2003) (orig. proceeding).

The Richeys’ expert testified generally that the trade secret information 

sought was “pertinent,” “helpful,” and “essential” to the Richeys’ claims and that 

the request was “reasonable” and “necessary.” But he never articulated any 

reason why discovery of the information was necessary other than that the only 

evidence the Richeys had to support their claims is the proximity of the wellbores 

on neighboring properties to their property. The Richeys’ expert admitted that 

the Richeys could have obtained the information on their own but for “cost and 

[lack of] expertise,” but he also testified that it “probably” would not do them any 

good to spend their own money on obtaining such information.

We conclude and hold that the Richeys did not meet their burden to show 

with specificity how their failure to obtain the trade secret information sought 

would so impair the presentation of the case that the result would be unjust; thus, 

the trial court abused its discretion by ordering production of the trade secrets. 

See, e.g., id.; see also HECI Exploration Co. v. Neel, 982 S.W.2d 881, 886 (Tex. 

1998) (noting that royalty owners should determine whether a common reservoir 

underlies their leases because of the potential for drainage by surrounding wells

and also noting that records about operations in a common reservoir are 
4

generally available from the former Railroad Commission). There is no adequate 

remedy by appeal when a trial court orders a party to produce privileged trade 

secrets absent a showing of necessity. See, e.g., In re Union Pac. R.R., 294 

S.W.3d 589, 593 (Tex. 2009) (orig. proceeding); In re Bass, 113 S.W.3d 735, 745 

(Tex. 2003) (orig. proceeding).

Accordingly, we conditionally grant mandamus relief. We order the trial 

court to withdraw its order compelling EOG to respond to the Richeys’ request for 

production number 10 seeking geologic and seismic data for the property and 

surrounding areas. We are confident that the trial court will promptly comply, and 

a writ will issue only if it does not.
