OPINION
Opinion by:
Relators ExxonMobil Production Company, Exxon Mobil Corporation, and Exx-onMobil Pipeline Company (collectively “ExxonMobil”) seek mandamus relief from the Starr County trial court’s denial of a motion to abate. ExxonMobil contends the Brooks County court has dominant jurisdiction over the Starr County suit because at the time the lawsuit was filed a suit was pending in Brooks County that was filed by real parties in interest the Encinitos Ranch and McGill Ranch Ltd. (collectively “Encinitos”) and involves the same parties and subject matter. We agree and conclude the trial court erred in failing to grant the motion to abate.
BACKGROUND
The Encinitos Ranch is comprised of more than 38,000 contiguous acres that extend through Starr, Hidalgo, Jim Hogg, and Brooks Counties. McGill Ranch, Ltd. is a partnership that owns a substantial portion of the surface estate of the ranch and manages the ranch. ExxonMobil is the lessee of most of the minerals underlying the ranch.
In 2007, a suit was filed in Brooks County by McGill Ranch, Ltd., the Encinitos Ranch, and members of the McGill family, acting individually and on behalf of five different trusts and one estate, (“plain
Generally speaking, this action is brought to recover damages for physical harm done to the land, to enjoin the defendants from further damaging the property, to enjoin further trespasses, to recover damages for trespass, to require lessees to implement reasonable and prudent programs, policies and procedures to safeguard and protect the property from any future damage, contamination or harm....
Plaintiffs assert claims for property damage, trespass to the property that arises from the contamination, pollution, and improper abandonment of oil field production facilities, equipment and infrastructure, negligence, and various breaches of the lease agreements. Additionally, plaintiffs assert claims for negligence, gross negligence, and breach of contract against the ExxonMobil defendants and another defendant in connection with a large fire that occurred on March 18, 2008 that allegedly resulted from poorly maintained power lines.
In 2010, a second suit was filed in Starr County by the Encinitos Ranch and McGill Ranch, Ltd. against only ExxonMobil Production Company, Exxon Mobil Corporation, and ExxonMobil Pipeline Company. Plaintiffs assert in their First Amended Petition as follows:
This is a lawsuit arising from Defendants’ acts and omissions in causing and continuing to cause chemical contamination to real property, including surface, subsurface and freshwater zones, located in Starr County, Texas. By virtue of this lawsuit, Plaintiffs seek equitable remedies requiring Defendants to clean up or remediate hydrocarbon, heavy metals and other identified contamination in Starr County at the ExxonMobil facility commonly known as Tank Battery 3 or Meter Site No. 3 and at the ExxonMobil facility commonly known as S.E. Kelsey Station, where irreparable injury to real or personal property is threatened and/or occurring.
Plaintiffs seek injunctive relief requiring defendants to abate and/or remediate the conditions causing the contamination, and assert claims based on negligence, negligence per se, trespass, nuisance, and breach of contract and implied covenants. Real parties in interest assert in their response in this court that the Starr County suit arose out of a June 2009 spill on the Encinitos Ranch in Starr County.
After filing an answer in the Starr County suit, ExxonMobil moved to abate the Starr County suit, asserting the Brooks County court has dominant jurisdiction because the Brooks County suit was filed first and involved the same parties and claims. Following a hearing, the trial court denied ExxonMobil’s motion to abate and subsequently denied its motion to reconsider. This petition for writ of mandamus ensued.
ANALYSIS
I. Standard of Review
Mandamus will issue only to correct a clear abuse of discretion for which the relator has no adequate remedy at law.
In re Prudential Ins. Co. of Am.,
II. Dominant Jurisdiction
As a general rule, when cases involving the same subject matter are brought in different courts, the court with the first-filed case has dominant jurisdiction, and the other case should be abated.
Wyatt v. Shaw Plumbing Co.,
In order to determine whether dominant jurisdiction exists, we must analyze whether there is an inherent interrelation of the subject matter between the two pending lawsuits.
Id.
at 247. It is not required that the precise issues and all of the parties be included in the first suit before the second suit is filed, provided that the claims in the first suit can be amended to bring in all of the necessary and proper parties and the claims.
See id
Therefore, in order for ExxonMobil to have succeeded on its motion to abate, it had to establish that (1) the Brooks County suit commenced first; (2) the Brooks County suit is still pending; (3) the Brooks County suit could be amended to include all of the parties; and (4) the controversies are the same or the Brooks County suit could be amended to include all of the claims.
See id.; In re Sims,
Encinitos does not dispute that the first three requirements have been met. Instead, Encinitos’s sole contention is that the controversies are not the same in the two cases. Encinitos argues that because the alleged damage from the June 2009 spill in Starr County had not yet occurred when the Brooks County suit was filed, the Starr County suit involves a discrete injury that is not the same as the controversy in the Brooks County suit. Encinitos offers no other explanation as to why the injury is discrete. In addition, Encinitos fails to explain why the Brooks County suit could not be amended to include the claims made in the Starr County suit. Pleadings can be amended to include subsequent claims; in fact, as previously noted, Enci-nitos amended its Brooks County suit to include claims for damages from a 2008 fire — a fire that occurred after the Brooks County suit was originally filed in 2007.
Here, based on the pleadings in both suits, there is an inherent interrelation of the subject matter between the two pending suits, and the Brooks County suit could be amended to include the claims in the Starr County suit.

III. Adequate Remedy by Appeal
In
Abor,
the Supreme Court held mandamus relief is not available to address a trial court’s erroneous refusal to abate a suit based on dominant jurisdiction unless there is a conflict in jurisdiction where one of the trial courts issues an order that actively interferes with the other court or enjoins the other from proceeding.
Abor v. Black,
In Prudential, the Supreme Court granted mandamus relief to a relator complaining of a trial court’s denial of its request to enforce an opposing party’s contractual waiver of a trial by jury. Id. at 138. In distinguishing between mandamus review of incidental, interlocutory trial court rulings and significant rulings, the Court explained that mandamus review of those incidental rulings “unduly interferes with trial court proceedings, distracts appellate court attention to issues that are unimportant both to the ultimate disposition of the case at hand and to the uniform development of the law, and adds unproductively to the expense and delay of civil litigation.” Id. at 136. However, the Court found that review of significant rulings in exceptional cases may be essential to: (1) preserve a relator’s substantive or procedural rights from impairment or loss; (2) allow appellate courts to give needed and helpful direction to the law that would otherwise prove elusive in an appeal from a final judgment; and (3) prevent the waste of public and private resources invested into proceedings that would eventually be reversed. Id.
The Court articulated a balancing test by which to determine whether there existed an adequate remedy on appeal.
Id.
An appellate remedy is adequate if the detriments to issuing mandamus relief outweigh the benefits; but if the detriments are outweighed by the benefits, “courts must consider whether the appellate remedy is adequate.”
Id.
The Court explained that prior cases in which it found an appellate remedy was inadequate “serve to illustrate that whether an appellate remedy is ‘adequate’ so as to preclude mandamus review
depends heavily on the circumstances presented
....”
Id.
at 137 (emphasis added). Elaborating that the decision of whether to

See, e.g., In re Team Rocket, L.P.,

Second, mandamus review presents this Court with the opportunity to give needed and helpful direction to the law.
See Prudential,
Third, the present case raises similar concerns as
Team Rocket
and
Flores
because the trial court’s failure to grant ExxonMobil’s plea in abatement will result in an irreversible waste of resources.
See In re Team Rocket,
IV. Waiver
Finally, Encinitos contends ExxonMobil waived its right to mandamus relief by waiting four months from the
The trial court signed the order denying the motion to abate on June 21, 2010, and on July 15, 2010, ExxonMobil moved for reconsideration. The trial court heard and subsequently denied ExxonMobil’s request for reconsideration on August 25, 2010. ExxonMobil filed its petition for writ of mandamus in this court on October 22, 2010. We conclude ExxonMobil did not unreasonably delay in filing its petition for writ of mandamus in this court.
See Hamel,
CONCLUSION
We conclude the trial court abused its discretion in denying ExxonMobil’s motion to abate. Accordingly, we conditionally grant the petition for writ of mandamus. The trial court is ordered to (1) vacate the June 21, 2010 Order Denying Defendants’ Amended Motion to Abate, and (2) enter an order granting Defendants’ Amended Motion to Abate. The writ will issue only if the trial court fails to comply within fourteen days.
