Kocurek Industries INC.

Kocurek Industries, Inc. / Hard Rock Division specializes in providing precision stone cutting for the oil and gas research industry. We are based in Caldwell, Texas and provide core samples that are used by major oil companies, universities, and research labs to gain a better understanding of oil and gas reservoirs around the world. To assist in our product selection we offer permeability and porosity testing in house.

Currently, core samples serve as one of the most valuable tools for reservoir analysis. Reservoir core analysis is conducted on the permeability and porosity of various types of rock formations to determine the ability of fluids to flow through the rocks and reservoir storage capacity. Our cutting-edge services and technologies make it possible to produce samples that can be utilized to develop more efficient reservoir production programs. The measurements  produced by laboratories can be used to make evaluations regarding the amount of oil and gas that may be present in a reservoir as well as the rates at which hydrocarbons can be produced. We take pride in supplying our customers with only the highest quality products at competitive prices. 

Our wide array of services includes cutting carbonate,marble, granite, shale and sandstone core samples. Along with cutting samples from stone provided by the customer, we also stock a large variety of stones quarried from locations around the world. Just a few of the various types of sandstone samples we stock at our Caldwell location include Berea ,Nugget, Colton, Kentucky, Crab Orchard, Bentheimer, Bandera, Scioto, Idaho, Williamsfork. Carbonates  include Indiana Limestone, Edwards Limestone, Austin Chalk, Kansas Chalk, Silurian Dolomite, Bonne Terre Dolomite.Shales include Mancos, Eagle Ford, Marcellus, Barnett, and Wolfcamp. We also stock and cut carbonate blocks, such as Indiana Limestone, Edwards Limestone, Austin Chalk, Kansas Chalk, Silurian Dolomite, Bonne Terre Dolomite. All of our cores can be cut using either brine, compressed air or oil saturation method, based on customer specific requirements. We can also provide rock properties with most of our in-stock stone.

In order to meet the continually evolving needs of our clients, Kocurek Industries, Inc., added a complete machining center that includes lathes and mills to produce core samples to any dimension including standard and metric sizes. This machinery also allows us to grind core ends parallel and square to exact tolerances.  Kocurek Industries, Inc. expanded our sawing capabilities by adding two large diamond saws. Our large saw turns a 120 inch diamond blade and the smaller saw carries a 72 inch diamond blade.  These saws give us the capability to custom saw very large quarry blocks to produce sizes our clients can easily handle. 

At Kocurek Industries, Inc., we understand the importance of delivery times and strive to meet the needs of our clients without sacrificing product quality.  All of our products are carefully inspected and packaged with utmost care to insure safe arrival at your location anywhere in the world.  You can depend on us for all your stone needs.
