Tjornehoj & Hack LLC invites you to join our attorneys Peter Hack and Katie Moisan as they speak at Denver Association of Petroleum Landmen’s luncheon on Wednesday, April 17, 2019. With continued expansion along Colorado’s Front Range and a tense political climate, landmen face growing issues concerning development in suburban areas. The presentation will provide practical solutions to avoid and correct title issues underlying subdivisions, including the severance of lot minerals, after-acquired title concerns, and the Colorado Common Interest Ownership Act.  The discussion will also focus on operational issues with regard to leasing and statutory pooling, as well as an effective approach to community outreach. The luncheon will be held from 11:30 a.m. to 1:00 p.m. at the Denver Athletic Club, located at 1325 Glenarm Place.  For more information, please visit

[February 13th, 2018]

Jon Tjornehoj and Alex Finch had the opportunity to present their "Anatomy of a Farmout Agreement" presentation to the Denver Association of Lease and Title Analysts (DALTA) at their first luncheon of the year. The presentation covered the structure, purpose, and function of a typical Farmout Agreement as well as the impact such an agreement can have on your chain-of-title and mineral title ownership.

Thank you DALTA for the opportunity and the wonderful crowd.

Law Center Gala

Tjornehoj & Hack, LLC recently attended the 35th Annual Legacy Gala celebrating the Rocky Mountain Children's Law Center. Our attorneys not only enjoyed the evening, but also the opportunity to support a great cause. In addition to corporate support, our attorneys actively volunteer with the Domestic Violence program and provide legal support for Colorado's most vulnerable population. The mission of the Rocky Mountain Children’s Law Center is to positively transform the lives of abused, neglected and at-risk Colorado youth through legal advocacy and public policy reform. The Rocky Mountain Children’s Law Center recently celebrated 25 years of their Domestic Violence Program, which is the only program in the nation providing legal representation for children in domestic violence cases. In 2016, the Domestic Violence Program provided guardian ad Litem representation for 271 children in 146 cases.

Katie Moisan and Jon Tjornehoj authored the article "Lis Pendens and the Shelter Rule" featured in the April, 2017 Rocky Mountain Landman newsletter published by the Denver Association of Petroleum Landmen. The article discusses the nature of a notice of lis pendens and its relationship to state recording statutes.  You can read our full article by clicking here.

This year we are pleased to again be one of the sponsors of the RMAG-DAPL Geo-Land Ski Day.  This year our t-shirt design features an image of the West Texas Intermediate oil price graph converted into the image of a mountain range.  To us, "Energy to Climb- Fortitude to Ride" encapsulates the spirit of those of us who have endured the rough ride that has been life in the oil and gas business over the past few years.  Peaks and valleys are a fact of life in our industry.  As Tjornehoj & Hack LLC celebrates its ten-year anniversary this summer, we are proud of the work we have done helping our clients navigate the tough terrain.

On February 14, 2017, the State of Colorado filed suit against the County of Boulder concerning its 5-year ban on accepting or processing oil and gas permitting applications.  The State of Colorado asserts that Boulder County's continued ban on oil and gas drilling permits flies in the face of decisions by the Colorado Supreme Court in 2016 that local governments are preempted by state authority from banning or materially impeding oil and gas activities.  The Boulder County Commissioners have repeatedly extended the county's "temporary" moratorium over the years under the guise of needing additional time to develop the county's permitting regulations.  The lawsuit filed by the Colorado Attorney General seeks to end the obvious delay tactics long implemented by the Boulder County Commissioners.  Undoubtedly, that history of delay has cost local landowners significantly in lost royalties that they may never recoup in today's price environment.     


As part of our sponsorship of the 2016 Geo-Land Ski Day (hosted by the Denver Association of Petroleum Landmen and the Rocky Mountain Association of Geologists) we gave to attendees t-shirts depicting a pickup truck hauling a few barrels of crude oil and a pumpjack in the background, with the message "Buy Local!"  Producing and refining crude oil is of course not a do-it-yourself job.  Our message was simply this: the oil and natural gas business is-- and has been for many years-- an important part of our local economy here in Colorado.  Our industry is comprised of people who live here and care about this place.  Contrary to the picture that some activist groups seek to paint, we are not faceless corporations residing in faraway places.  The thousands of people who support their families through oil and natural gas development in Colorado are people who believe in our work and love where we live.  We are locals and we are here to stay.

On May 2, 2016, the Colorado Supreme Court issued its decision striking down the ban on hydraulic fracturing enacted by the city of Longmont, Colorado.  The Colorado Supreme Court ruled that Longmont's ban on the process conflicted with the extensive regulatory regime enforced by the Colorado Oil and Gas Conservation Commission and was therefore preempted by state law.  The Colorado Supreme Court's decision was in line with previous decisions striking down attempts by municipalities to override comprehensive oil and gas regulations enacted on a statewide level.  

The County of Boulder, Colorado, continues to flaunt the Supreme Court's recent decision through continued enforcement of its de facto ban on all oil and gas drilling activities in unincorporated areas.  The Boulder County drilling ban is under the guise of a "moratorium" on processing oil and gas permit applications that has been in force for four years and is currently scheduled to extend at least through the year 2018.
