Dan and Farris Wilks

Daniel Howard "Dan" Wilks (born 1955 or 1956) and Farris Cullen Wilks (born 1951 or 1952), also collectively known as the Wilks Brothers, are American petroleum industry businessmen. Sons of a bricklayer, the brothers established Wilks Masonry in 1995. They went on to found an early hydraulic fracking company, Frac Tech, in 2002, and eventually became billionaires. In 2011, they sold their 70% interest in Frac Tech for $3.5 billion. They reside in Cisco, Texas.

They are major investors in and funders of conservative causes, including The Daily Wire, PragerU, and the 2016 presidential campaign of Senator Ted Cruz.

Early lives
The brothers are sons of Myrtle and Gwyn Voy Wilks (went by his middle name) of Cisco in Eastland County, east of Abilene, Texas. When the brothers were born, their father worked as a bricklayer and the family was destitute; the brothers once slept in a goat shed.

Assembly of Yahweh (7th day)
In 1947, Voy and Myrtle Wilks along with Myrtle's father Charlie Cullen Fenter were disfellowshipped from the Churches of Christ and founded a church which was at first called simply “A Church of Christ.” The church is not Christian, believing that Yahweh is the only god and that Jesus (called Yahushua) is a separate entity. In early 1952 Charles restricted communion to once a year rather than weekly and moved worship from Sunday to Saturday. The Fenters and Wilkses along with a few other families left the congregation and began to meet in private homes. When Charlie Fenter died in May 1952, Voy took over the congregation and the couple and their five children continued to live at the home of Charlie's widow, Annie.

In 1962 they adopted the name Church of God (7th day) (not to be confused with Church of God (Seventh-Day)); in 1982 the church became the Assembly of Yahweh (7th day). Currently the Assembly of Yahweh (7th day) is a conservative Jews for Jesus-type congregation. It teaches that "the true religion is Jewish (not a Gentile religion)" and its members celebrate the Old Testament holidays rather than those related to the New Testament. The congregation considers the Old Testament historically and scientifically accurate. The congregation considers homosexuality and abortion to be crimes.

Farris Wilks
Farris Wilks is married to Jo Ann and is the father of 11 children. He is the current pastor and bishop of the Assembly of Yahweh (7th day) near Cisco. In sermons, he has denounced homosexuality and abortion rights.

Dan Wilks
Dan Wilks is married, with six children, and lives in Cisco, Texas.

Frac Tech
In 2002, the brothers founded a hydraulic fracturing company called Frac Tech. In 2011 they sold their 70% interest in Frac Tech for $3.5 billion.

Idaho land purchase and restrictions
As early as 2016 the Wilks Brothers began purchasing large quantities of land in Central Idaho, mainly in Ada, Boise, and Valley counties. They restricted access to the locals with gates, with anti-vehicle ditches, and with no-trespassing signs appearing soon after their acquisitions. They informed Valley County that they were terminating leases to roads and snowmobile trails, including a main road which was the only access to public lands. According to the United States Forest Service, some of the brothers' restrictions were illegal. The brothers' frequent refusal to allow hunting, snowmobiling, firewood cutting and transit frustrated locals. In 2017 a video emerged of an armed and uniformed DF Development security guard illegally expelling an outdoorsman from a public road, Forest Road 409 (Clear Creek Road), which runs through Wilks brothers land, on grounds of trespass. According to the Valley County Roads Department superintendent, the DF Development guard was in the wrong, as both the road and a 33-foot easement on either side belong to the county, and as such are public land.

As of 2019, the Wilks brothers' shell company, DF Development, owned approximately 75,000 acres of land across 306 parcels in Valley County. Overall the Wilks brothers own about 200,000 acres in Idaho.

As of 2018, many of the parcels of land owned by the Wilks Brothers have been listed for sale via Wilks Ranch Brokers, LLC. As of 2019, Wilks Ranch Brokers had listed 54,000 acres of Idaho land for sale.

Montana land purchase and restrictions
In Montana, the Wilks brothers asked the Bureau of Land Management if they could swap a piece of their Duffee Hills ranch for a parcel of public land. This request was denied after local hunters objected on the grounds that the brothers had closed down an access road to the wild and scenic Missouri River.
