Nostra Terra's assets and operations are focused on low-risk exploration and developmental drilling in the onshore areas of the Mid-continental USA.

We target basins that have proven to be long-lived, liquids-rich production areas. Through the application of modern techniques of drilling and multi-stage fracture completions, we reach into compartmentalized reservoirs and greatly improve the economics of multiple formations. Because much is already known about the rock properties and production profiles, much of the geological risk is mitigated. These methods have created exciting new growth opportunities in well-understood reservoirs.

Permian Basin

The Permian Basin is one of the premier oil and gas producing regions in the world. Straddling New Mexico and Texas, the Permian Basin is approximately 240 miles wide and 300 miles long. In June 2014, the Permian Basin was estimated to be the world's second largest oil field in terms of total recoverable resource, with at least 75 billion barrels of oil equivalent recoverable resources present.

Within the Permian Basin Nostra Terra is focusing on shallow, conventional reserves. Nostra Terra has 50% to 75% working interest in leases located in Mitchell County, Texas. All leases are Held By Production, giving Nostra Terra full control over the timing of any future capital expenditure decisions.

Pine Mills Oilfield

Since it was discovered in 1950s, the Pine Mills field has produced over 12 million barrels of oil.

Pine Mills is a 2,400-acre producing oil field located in Wood County, Texas. All leases are Held By Production, giving Nostra Terra full control over the timing of any future capital expenditure decisions. Nostra Terra owns 87.5% working interest and is the operator.

White Buffalo Prospect

The White Buffalo Prospect is in the Big Horn Basin of Wyoming. It is close to two significant fields producing from the Phosphoria Formation and covers approximately 90 square miles. Nostra Terra owns approximately 6,000 net mineral acres in the play and operates 100% of the Working Interest.

The Phosphoria Formation is both source rock and reservoir. It is the source for both the Permian Tensleep and Minnelusa formations in Wyoming and for the Leo and Weber Sandstones in Colorado. The Manderson Field was discovered in 1951 and the Cottonwood Creek Field was discovered in 1953 and each is a structural/stratigraphic trap producing from the Phosphoria and other zones. Cottonwood Creek alone has produced 60 MMbo and 67 BCf from the Phosphoria and is the largest stratigraphic oil accumulation in the Big Horn Basin. In addition, the Muddy and Frontier Formations, above the Phosphoria, have also been productive in the area. Success in the Phosphoria has been dependent on the wellbore randomly intersecting natural fractures. Where this occurred, wells could be highly prolific. However, just as in the Barnett Shale of Texas, wells almost always encountered only shows of oil or gas but were too low in porosity and permeability to be produced. Many drill stem tests only recovered small volumes of drilling mud and slight shows of oil and gas. Horizontal drilling and new, multi-stage frac technology appear to be well-suited to the enhanced recovery of hydrocarbons from this dense, stratified, compartmentalize dolomite.


basin mapThis prospect is located in a portion of the Anadarko Basin of Central Oklahoma. The Anadarko is one of the richest hydrocarbon reservoirs in North America and stretches from the Texas Panhandle through Western Oklahoma and into southern Kansas. The very thick sedimentary column can reach accumulation of up to 40,000 feet.

The "Sooner Trend" refers specifically to a group of stacked reservoirs within the Anadarko Basin in Alfalfa, Blaine, Garfield, Kingfisher and Major Counties. Ward Petroleum generated a horizontal drilling program that is situated very close to a "cowboy era" cattle drive known as the Chisholm Trail. In late 2012 Nostra Terra acquired a 20% interest in the prospect (individual Working Interest varies due to Forced Pooling) and Nostra Terra divested its core interest in 2016 at a profit. The company still holds small interests in the play.

Onal drilling and production techniques have greatly enhanced the economics of producing hydrocarbons, leading to very profitable horizontal development of the Hunton formation.

In the Sooner Trend of Central Oklahoma the major producing formations are:

  • Mississippian
  • Woodford
  • Hunton
  • Wilcox
  • Viola
  • Simpson

High Plains Prospect

generalized cross-section of anadarko basinThe High Plains Prospect is located in the Western Anadarko Basin of the North Texas and Oklahoma Panhandles. This prospect is based on the re-evaluation of 3D seismic to identify drill targets for acquisition and drilling. The proprietary data covers more than 42,000 acres of highly prospective reservoirs. The first phase of evaluation has been completed and targeted leases have been purchased. Nostra Terra has a 20% Working Interest. The prospect is operated by Brown & Borelli.

The many prolific oil-prone formations, include:

  • Tonkawa
  • Cottage Grove
  • Cleveland
  • Hogshooter
  • Granite Wash
  • Canyon Wash
  • Marmaton
  • Atoka
  • Morrow Sandstone
  • Mississippian

Additional Assets

Nostra Terra has additional producing assets in the Mid-continent of the USA, including a significant working interest in Baca County, Colorado, operated by Plainsmen Partners and Ramsey Properties.
