It is barely eight o’clock in the morning when Gloria Moncrief arrives at her oil firm’s private hangar at Meacham Airport in Fort Worth, Texas, ready to embark on a journey that bridges the gap between polished corporate power and the raw, unpredictable frontier of American energy. Today, she climbs into an eight-seater Cessna Citation, casually explaining that her usual Boeing 737, affectionately named Lucky Liz, is currently in the repair shop. The hour-long flight from Texas lands her at a modest, sun-baked airfield in southern Louisiana, but the real journey begins when she steps into an SUV for a forty-five-minute drive along the elevated levees into the Atchafalaya River Basin—the largest wetland and swamp in North America. To finally reach her destination, Gloria must swap the vehicle for a flat-bottomed boat, navigating a fifteen-minute winding course past sunbathing alligators, nesting bald eagles, and local fishermen maneuvering their bass boats through the cypress-choked bayous. Rounding a final bend in the waterway, the primeval quiet of the swamp is shattered by the deafening roar of a colossal industrial island: a giant drilling rig boasting a 150-foot derrick and engines that shake the humid air. Standing tall and lean, dressed in simple jeans and a pair of head-turning, knee-high ostrich-skin boots, the forty-four-year-old heiress and executive steps firmly onto the deck, where a crew of mud-spattered roughnecks operates massive hydraulic tongs to swing forty-foot segments of heavy steel pipe into place. As the leader of Montex Drilling Company—the operational arm of her family’s legendary Moncrief Oil—Gloria is currently overseeing a staggering outlay of $300,000 a day to lease this rig, keeping sixty crew members working grueling twelve-hour shifts around the clock on a two-week rotation. They are here to conquer the Highlander 2, a geological marvel that plunges an astounding 30,862 feet into the Earth—nearly six miles down—where it taps into an 800-foot-thick subterranean formation saturated with trillions of cubic feet of natural gas. Releasing these deep reserves is perhaps the most audacious high-wire act in the modern energy sector, representing a $300 million personal bet on an ultra-deep play that rivals walked away from, and Gloria is now searching for strategic partners to secure the $2 billion required to hook up the well, build a processing plant, and unleash a multi-well developmental campaign.
To understand why a woman would risk her family’s hard-earned fortune on a geological deposit six miles beneath a Louisiana swamp, one must realize that Gloria has crude oil running through her veins and the grit of legendary wildcatters woven into her genetic code. The Moncrief saga began in 1927 when her great-grandfather, William A. “Monty” Moncrief, a former World War I machine gunner, took to the Texas fields; after drilling over a dozen heartbreakingly dry holes, he struck oil in 1931, discovering a legendary billion-barrel pool in East Texas. The legacy was fortified when his son, William A. “Tex” Moncrief Jr., joined the business in 1945, using his charm and financial acumen to recruit high-profile investors—including his regular golf partners Bing Crosby and Bob Hope—to build one of the absolute largest family-owned petroleum empires in American history. They successfully secured a place on the very first Forbes 400 list in 1982, cemented by their pioneering discovery of the massive Madden Deep gas field in Wyoming a decade prior. Yet, this extreme wealth and unyielding pursuit of oil occasionally brought dramatic storms; in 1994, the Internal Revenue Service executed a massive raid on the Moncrief offices, hauling away 300 boxes of private financial records and dozens of filing cabinets in a maneuver that defense attorneys described as a gestapo-style overreach, which Tex eventually settled in 1996 for $23 million. Tex’s complex personal life led to eight children across two marriages, and while his eldest son, Charlie—Gloria’s father—was groomed as the natural heir apparent, it caused long-standing friction with his half-brother Richard, who pursued his own independent ventures abroad, highlighting the intense, sometimes Shakespearean dynamics of the Moncrief dynasty.
Growing up around these larger-than-life figures, Gloria caught the wildcatting bugs early, declaring even as a young girl that she was destined for the family business because she craved the fast-paced action of the oil patch. After graduating from the University of Texas at Austin—where she shared a room with Jenna Bush—and serving a brief, eye-opening stint in the United States Department of State during President George W. Bush’s second term, she returned to Fort Worth in 2009 to take her place in the family office. Her initiation was an immediate baptism by fire: on her very first day, the charismatic James Robert “Jim Bob” Moffett, then-chairman of mining giant Freeport-McMoRan, walked in to pitch her father and grandfather on an ultra-deep exploration project in Louisiana. Moffett had acquired the infamous Blackbeard site from ExxonMobil, which had abandoned the well after sinking $300 million into the earth without success, but he rolled out seismic surveys claiming that reservoirs of natural gas lay trapped in hundred-million-year-old rock formations beneath the Gulf. Tex and Charlie bought in for a ten percent stake, giving young Gloria a front-row seat to the high-stakes engineering negotiations, and she absorbed every detail of the subsequent Davy Jones project. Although that well reached an impressive 29,000 feet, extreme downhole temperatures peaking at 440 degrees Fahrenheit and crushing atmospheric pressures caused disastrous mechanical failures, forcing them to abandon the project in 2012. Yet, rather than discouraging the Moncriefs, this heartbreaking setback only intensified their obsession with the deep, leading to a series of dry holes before they finally achieved a breakthrough in 2014 with the original Highlander well, which produced a highly lucrative 75 million cubic feet of gas per day.
The triumphs of the deep, however, were soon overshadowed by immense personal tragedy and internal family warfare that threatened to dismantle everything the Moncriefs had built over three generations. In 2017, Charlie Moncrief was diagnosed with aggressive brain cancer, and Gloria stepped up to drive her father to his daily radiation treatments, utilizing those quiet, emotional car rides as invaluable mentoring sessions where Charlie passed down the wisdom, strategies, and survival instincts she would need to protect the empire. He looked at her and plainly stated that the entire weight of the family name, assets, and future was about to fall squarely on her shoulders. When both her beloved father and her legendary grandfather Tex passed away in 2021, the transition of power was anything but smooth; her uncle Richard stepped forward, attempting to fire the chief financial officer and vocally protesting the idea of a woman running a multi-million-dollar oil exploration company. Gloria refused to back down, immediately taking the matter to court and securing critical legal victories to affirm her leadership, a display of resilience that surprised outsiders but was fully expected by her mother, Kit Moncrief, who serves as the board chair of Texas Christian University and president of the Texas Cowgirl Museum Hall of Fame. Kit proudly noted that Gloria was always the one destined to take the reins, possessing the absolute toughness required to thrive in a notoriously male-dominated industry where weakness is quickly exploited.
Just as Gloria consolidated her grip on the executive suite, disaster struck the physical operations in January 2023 when she received a devastating phone call informing her that the original Highlander well had collapsed after water infiltrated the deep formation, cutting off the gas flow and rendering the entire multi-million-dollar asset a total loss. Rather than succumbing to despair, Gloria recognized a strategic opportunity: she negotiated to buy out her partner’s remaining stake in the lease through Montex and secured a massive $300 million insurance settlement that was legally earmarked specifically for drilling a replacement well. While industry skeptics question why anyone would waste capital drilling six miles into the earth when cheap domestic shale gas can easily be fracked near the surface, Gloria’s decision is actually a brilliant play that exploits the very nature of the modern shale revolution. The absolute abundance of cheap American shale gas led to the construction of massive, multi-billion-dollar liquefied natural gas (LNG) export terminals scattered along the Gulf Coast, and these massive facilities possess an insatiable appetite for consistent fuel supplies. Because the Highlander 2 well sits incredibly close to existing coastal pipeline networks, Gloria plans to bypass the logistical hurdles that plague other players, aiming to connect her deep-well production directly to these export channels by the end of 2027 to capture premium international pricing.
As a late-afternoon storm begins to brew over the southern horizon, Gloria boards her Cessna Citation to begin the journey back to Fort Worth, watching the dark clouds gather outside her window. Showing the same hands-on, decisive leadership she uses on the drilling rig, she stands up from her seat, walks to the cockpit, and calmly requests that her pilots steer a wide path around the massive thunderheads blocking their flight path home. It is a quiet, telling moment for an executive who has navigated some of the most turbulent corporate and personal storms imaginable over the past three years. Back on the ground in Texas, she remains completely committed to the promises she made to her father and grandfather in their final days, driven by a deep sense of familial duty and an unshakeable belief in her geological gamble. With the Highlander 2 well successfully completed, she is ready to face the next financial hurdle, confident that she can secure the partners needed to transform this deep swamp discovery into a generational triumph. In an industry where fortunes are made and lost on the roll of a geological dice, Gloria Moncrief has proven that she possesses the vision, the legacy, and the unyielding willpower to conquer the deepest depths of the American wildcatting frontier.
