OPINION
This аppeal stems from the sale of a mineral interest in 1998. Strapped for cash, Appellant Bland Holland sold his interest for $9,027.27. Subsequent field development netted the purchasers revenues of hundreds of thousands of dollars. Simply stated, we must decide who knew what when. The trial court entered summary judgment in favor of the purchasers— James Cleo Thompson, Jr., individually and as executor of the estate of J. Cleo Thompson; J. Cleo Thompson and James Cleo Thompson Jr., a partnership; and J. Cleo Thompson and James Cleo Thompson, Jr., L.P., collectively Thompson. 1 For the reasons that follow, we affirm on limitations grounds.
FACTUAL BACKGROUND
Holland Inherits the Mineral Interest
Holland’s family owned mineral interests in the Bailey Estate Trust for decades. When his mother passed away in 1996, Holland inherited a l/48th beneficial interest in minerals held in the Bailey Estate Trust. The trustees of the Bailey Estate *590 Trust hold title to and administer the mineral interests located in Crockett County.
The Role of J. Cleo Thompson, Jr.
J. Cleo Thompson, Jr. acquired a ranch in Crockett County in 1967. In 1969 or 1970, he purchased the majority working interest in the oil and gas leases in the Bailey Estate Trust and became the operator. By the time of the events giving rise to this litigation, Thompson had cоntrolled production on the Bailey leases for 28 years, making all decisions regarding drilling and production. Thompson purportedly held himself out as the person the local residents could trust in oil and gas matters.
Negotiating the Sale
In 1998, Holland was living in Florida and operating a bed and breakfast establishment. He became embroiled in a lawsuit concerning the inn and learned that his cousin 2 had sold mineral interests to Thompson. In September 1998, Holland wrote to Thompson, asking if he would be interested in purchasing Holland’s interest. Thompson and Holland exchanged a number of telephone cаlls and emails.
Thompson offered Holland $9,000 based on a standard formula of production from the past year times four. He told Holland that the current wells were “old” and “playing out.” Holland admitted that he did not believe this to be untrue. Thompson represented that there was “no reason” to begin new production and that he did not “foresee” any. Holland later believed this to be a misrepresentation based upon what new wells were producing as of the date of his deposition in 2007. Thompson also agreed to purchase the mineral interest as a favоr although he would “probably never see this money back.” Thompson’s assistant, Mary Lou Wright, also emailed Holland, telling him there would be no future production and that the field was “drained” or “used up.” 3 Thompson opined that $9,000 was a fan-value for Holland’s mineral interest and that a fair price would be based only on current production because “there was nothing else there.”
As was required by the trust agreement of the Bailey Estate Trust, Holland first offered his mineral interest to the trustees. When they rejected the tender, Holland inquired whether his siblings were interested. Holland ultimately sold Thompson his interest on November 25, 1998 for $9,027.27.
1997 Texas Railroad Commission Filings
In July 1997, Thompson applied to amend the field rules for the Ozona NE. (Canyon 7520) Field (67998 500), Crockett County, Texas, to amend the well spacing of 132072640' to 66071320'. The application was prepared by Thompson’s petroleum engineer, Sol Smith. The purpose of the application was to “afford greater flexibility in locating wells on the most favorable geological location; thus recovering greater reserves and preventing waste.” Smith also averred that, “[d]ue to the event of 3-D geological surveys, the best areas to drill are shown.” Proper notice was given for a hearing on July 30, 1997. The application was unprotested and the *591 technical hearings examiner recommended approval. In her findings of fact, the examiner recited that there were 68 producing wells in the field, 56 of which were operated by Thompson. Of Thompson’s 56 wells, 29 were Bailey wells. 4 In Findings of Fact 4 and 5, the examiner found that:
4. Thompson plans to drill at least 15 wells under the optional 160 acre optional rule. Many of the proposed locations, identified from 3-D seismic, would require exceptions to Rule 37 under the existing spacing rules. 5
5. The proposed sрacing rule will allow additional wells to be drilled without the time and additional cost associated with obtaining rule 37 exceptions.
In Conclusion of Law 3, she found that amending the field rules would provide for effective and efficient field development. The Commission signed a final order approving the application on August 26, and it became final on September 19, 1997. Despite the changes in the permit and the abundant reserves, Thompson did not drill any new wells.
Development of the Reserves
In November 2003, Thompson was contacted by Approach Resources, Inc. about taking a farm out agreemеnt on leases held by Thompson. Beginning in 2004, Approach drilled numerous wells under the farm out agreement, beginning on the Bailey leases. 6 Charles Graham, a petroleum engineer, explained in his affidavit that the Bailey leases were situated in the Ozona NE. (Canyon 7520) Field and were producing natural gas in paying quantities. He offered his opinions on the extent of undeveloped hydrocarbon reserves in the Canyon sand reservoirs underlying the Bailey leases. Technical evidence revealed that the existing wells could not recover the reserves underlying the proration units assigned. Documents on file with the Commission supported his conclusions as to the undeveloped reserves. But Thompson did not drill on the Bailey leases in 1998, 1999, 2000, 2001, 2002 or 2003. In Graham’s opinion, Thompson knew of significant undeveloped hydrocarbon reserves under the Bailey leases prior to 1998.
Thompson admitted that he netted $438,319.23 from Holland’s interest between October 1998 and January 2008. Thompson continues to collect revenues from Holland’s property. Graham calculated the present value of Holland’s interest at $340,235.
The Lawsuit
Holland filed suit against Thompson in April 2006 alleging breach оf fiduciary duty 7 , common law fraud (fraudulent misrepresentation and/or fraudulent induce *592 ment); fraud by non-disclosure; fraud under Texas Business & Commerce Code, Section 27.01; money had and/or received; and constructive fraud. Thompson filed a motion for traditional and no-evidence summary judgments alleging multiple grounds, including that the suit was barred by limitations. The trial court granted the motion without specifying grounds.
LIMITATIONS
Holland challenges the summary judgment in eight points of error. With regard to the statute of limitations, he contends that both the discovery rule and the doctrine of fraudulent concealment tolled limitations and that Thompson failed to рrove when he knew or should have known of his injuries.
Standard of Review
The standard of review for traditional summary judgment under Tex.R.Civ.P. 166a(c) is well established.
Nixon v. Mr. Property Management Company, Inc.,
When reviewing a no-evidence motion for summary judgment, wе must disregard all contrary evidence and inferences, and review the evidence in the light most favorable to the non-movant.

The Parties’ Positions
Holland’s causes of action against Thompson stemmed from claims of fraud. The longest limitations period afforded to any of his claims is four years.
See
Tex.Civ.Prac. & Rem.Code Ann. § 16.004 (Vernon 2002). Ordinarily, the statute of limitations begins to run when a particular cause of action accrues. S.V.
v. R.V.,
The Discovery Rule
In those rare cases when the nature оf the injury incurred is inherently undiscoverable and the evidence of injury is objectively verifiable, the Texas Supreme Court applies a judicially crafted exception to the general rule of accrual, known as the discovery rule.
Computer Assocs. Int’l, Inc. v. Altai, Inc.,
Thompson argues that the discovery rule does not apply to this lawsuit because fraud claims are governed by the separate and distinct doctrine of fraudulent concealment. S.V,
We have not applied [the legal injury] rule without exception, however, and have sometimes held that an action does not accrue until the plaintiff knew or in the exercise of reasonable diligence should have known of the wrongful act and resulting injury. S.V.,933 S.W.2d at 4 . This exception, which we call the ‘discovery rule’, applies in cases of fraud and fraudulent concealment, and in other cases in which ‘the nature of the injury incurred is inherently undiscoverable and the evidence of injury is objectively verifiable.’ Computer Assoc.

the plaintiffs were members of the Neel family who owned royalty interests under an oil and gas lease.
As owners of an interest in the mineral estate, the Neels had some obligation to exercise reasonable diligence in protecting their interests. This includes exercising reasonable diligence in determining whether adjoining operators have inflicted damage. Rоyalty owners cannot be oblivious to the existence of other operators in the area or the existence of a common reservoir. In some cases, wells visible on neighboring properties may put royalty owners on inquiry. In any event, a royalty owner should deter *595 mine whether a common reservoir underlies its lease because it knows or should know that, when there are other wells drilled in the reservoir, there is the potential for drainage or damage to the reservoir.
Id. at 886. The court emphasized that several sources of information about the existence of a common reservoir and operations within it were available to the royalty owners, including Texas Railroad Commission and lessee records. Id. at 886-87. The court held that because damage to the common reservoir was not inherently un-discoverable, the lessee’s failure to notify the Neels of them potential claims did not toll limitations. Id. at 887.

The record here contains the affidavits of two petroleum engineers. Tim Smith explained that when analyzing and evaluating mineral interests, petroleum engineers often refer to and rely on information that is commercially available, including the Texas Railroad Commission records. The types of information available from the Commission in 1998 included its Mapping Information Management System (MIMS) and associated quad reports, potential files, hearing files, pro-ration schedules, production information, and in some cases well logs. The affidavit of Charles Graham opined that Commission files in existence prior to 1998 revealed that Thompson should have already engaged in additional dеvelopment of the Bailey leases. Even a cursory review of the 1997 application would have revealed the possibility that significant reserves existed on the Bailey leases in the Ozona NE. (Canyon 7520) Field because the Gas Proration Schedule listed them. And regardless of whether Thompson later denied that he planned to drill fifteen wells, a prudent mineral interest owner would certainly have reason to inquire about future production based on Sol Smith’s representations in the application. Because Holland’s injury was not inherently undis-coverable, the discovery rule does not toll limitations. 8
Fraudulent Concealment
Holland next contends that he raised multiple material issues of fact as to the elements of the fraudulent concealment doctrine. He claims that Thompson gave him false information concerning the sta *596 tus of the undeveloped reserves and potential for future production. Specifically, Holland was told the field was “played out” and that no further production was likely to occur. He also maintains that once Thompson made a partial disclosure, he was obligated to fully disclose the information аvailable to him.
Fraudulent concealment works to estop a defendant from asserting limitations as a defense because “a person cannot be permitted to avoid liability for his actions by deceitfully concealing wrongdoing until limitations has run.” S.F.,
Common Law and StatutoRy Fraud
To establish common law fraud, Holland must demonstrate that: (1) Thompson made a material and false representation of fact; (2) Thompson made the representation knowing it to be false or made it recklessly as a positive assertion without any knowledge of its truth; (3) Thompson intended for Holland to act upon the representation; (4) Holland acted in reliance upon the representation and suffered injury as a result.
Eagle Properties, Ltd. v. Scharbauer,
An actionable representation is one concerning a material fact; a рure expression of opinion will not support an action for fraud.
Trenholm v. Ratcliff,
Holland contends that Thompson had special and superior knowledge when he made the offer. But the affidavits of Smith and Graham reveal that information concerning future drilling operations was readily available to Holland from the Commission records. The comparative levels of Thompson’s and Holland’s knowledge could not have been disproportionate because Holland had a duty to exercise reasonable diligence in valuing his own mineral interests.
Our analysis is guided by
Pauli v. Capital Resource Management, Inc.,
As in Pauli, Holland cannot claim that Thompson had special knowledge. Holland’s own expert reached his conclusions based on the Commission records that were equally available to both buyer and seller. Thompson also argues that even though the Commission records reflect an intent in 1997 to drill additional wеlls in the next year, that does not support the inference that his later statements to Holland in 1998 were false. We agree. Drilling did not begin until 2004 — six years later — and circumstances had changed, including increased gas prices and improvements in drilling technology. Even if Thompson’s statements regarding future production were material representations rather than non-actionable opinion, the evidence does not raise a genuine issue of material fact that the statements were false when made or that Thompson knowingly or recklessly made them.
Fraud By Non-Disclosure
Fraud by omission may occur: (1) when a defendant conceals or fails to disclose a material fact within his knowledge; (2) the defendant knows the plaintiff is ignorant of the fact and does not have an equal opportunity to discover the truth; (3) the defendant intends to induce the plaintiff to take some action by concealing or failing to disclose the fact; and (4) the plaintiff suffers injury as a result of acting without knowledge of the undisclosed fact.
Bradford v. Vento,
The failure to disclose information is not actionable unless there is a duty to speak. The duty arises in four circumstances: (1) a fiduciary or other special relationship between the parties gives rise to a duty to disclose; (2) new information makes a defendant’s earlier representation misleading or untrue; (3) a defendant conveys a false impression by making a partial disclosure; and (4) a defendant who voluntarily discloses information has a duty to disclose the whole truth.
Lesikar v. Rappeport,
Equitable Claims
Constructive fraud is the breach of a legal or equitable duty which the law declares fraudulent because it violates a fiduciary or confidential relationship.
See Texas Integrated Conveyor Systems, Inc. v. Innovative Conveyor Concepts, Inc.,
CONCLUSION
We conclude that since the record does not support the existence of an underlying tort, the doctrine of fraudulent concealment does not apply. The accrual of Holland’s claims was not deferred and the claims are barred by the statute of limitations. We affirm the summary judgment on limitations grounds.
Notes
. J. Cleo Thompson, deceased, was the father of James Cleo Thompson, Jr. The two were in partnership together when they first acquired the Bailey leases in the late 1960's. When the father died in 1975, Thompson Jr. operated the leases through a partnership known as J. Cleo Thompson and James Cleo Thompson, Jr., a Partnership. The entity later became known as J. Cleo Thompson and James Cleo Thompson, Jr., L.P. The latter entity was the current operator on the leases.
. Bland Holland and Martin Brock Jones, Jr. are cousins. We have issued this same date an opinion in a lawsuit Hied by Jones against the Thompson defendants relating to his sale of a mineral interest in the Bailey Estate Trust.
. During his deposition, Holland characterized Wright as “the messenger.” He did not believe that she told him something that was falsе.
. We have obtained these calculations from the July 1997 Gas Proration Schedule which Thompson attached as an exhibit to the application. According to the affidavit of one of the petroleum engineering witnesses, pro-ration schedules identify every well in each oil and gas field designated by the Commission.
. Thompson testified that the 3-D geological surveys were not performed until after the farm out agreement with Approach. He disputed Smith's statement that "[d]ue to the event of 3-D geological surveys, the best areas to drill are shown.” He also denied any plan to drill fifteen wells. Thompson's chief financial officer, Cliff Milford, thought the application contained a simple grammatical error: it should have read ”[d]ue to the advent of" rather than “[d]ue to the event of” 3-D geological surveys. Milford also took issue with the examiner’s finding that Thompson was going to drill fifteen wells. “There was no plan to drill.”
. Thompson testified that when Approach started drilling, they started on the Bailey and Clayton leases. His chief financial officer, Cliff Milford, disagreed.
. Holland later abandoned this theory.
. Because we conclude that the injury was not inherently undiscoverable, we need not consider whether it is objectively verifiable.
