Limestone Oil Corporation

An oil and natural gas exploration and production company that generates prospects and drills oil and natural gas wells in well-known

oil-producing regions of the United States.

Investor inquiries are welcome.

Sedimentary layers of limestone are easy to see on the surface in Texas.

This is a picture of Interstate 10 near San Antonio. Layers of Limestone can be seen in the road cut in the upper left. These layers of limestone exist throughout much of Texas west of San Antonio; and although we cannot see them in this photograph, these layers of Limestone continue down for thousands of feet below the surface. Many of the ones in west Texas are saturated with crude oil.

How were these thick Limestone formations created?

Throughout much of the Paleozoic era between 500 and 250 million years ago, the area we know as Texas was covered by shallow seas like the one in the main picture above. The white material shown in the inset in the upper left is a modern shallow sea bed. It’s composed of the calcareous remains of organisms including corals, shelled animals, and plants that have fallen to the sea floor. During the Paleozoic era in Texas, these kinds of deposits built up over millions of years to form thousands of feet of limestone like the ones along Interstate 10. Some of those layers were later saturated with oil which we seek to produce. Hence the company’s name Limestone Oil.

The Ellenburger Dolomite is a specific example of a carbonate deposited in the shallow seas of Texas during the Ordovician Period approximately 400 million years ago.

This is a photograph of a roadside outcrop of the Ellenburger Dolomite along Highway 71 about half way between Austin and Midland. This same formation is buried thousands of feet below the surface in the Permian Basin and it is a well-known producing horizon in the area.

This map from the U.S. Geological Survey shows the locations of hundreds of thousands of oil and gas wells that have been drilled in the U.S. over the last century. Each green dot represents an oil well and each red dot represents a natural gas well.

Hundreds of Thousands of Oil Wells in the Permian Basin

Zooming in now to just one part of one county in Texas: This map shows the oil wells that have been drilled in just one part of Crane County, Texas.

Each green dot on this map represents one oil well.

Hundreds of thousands of oil wells have been drilled in Texas; but there are still countless locations remaining to be drilled at many different depths.

Zooming in even further, we focus on a smaller area of interest and create a detailed map of the smaller area.

Next we slide the map of the smaller area…

…on to the top of an imaginary 3-dimensional cube…

Like this. Using computers, we visualize the subsurface contours of the oil-productive layers penetrated by the previously-drilled wells in 3D and identify locations to drill new wells.

Once a location has been identified, a drilling rig like the one pictured here is used to drill a hole in to the ground.

After a well is drilled, a pump jack like this is used to lift the oil to the surface.

Limestone Oil Corporation uses information from wells that have already been drilled to locate promising locations to drill new wells.

As the maps show, and the subsurface 3-D data proves, there are countless locations remaining to be drilled - and millions of barrels of oil to produce!
