With our technical associates, Texas OilTech Laboratories ffers both Routine and Special Core Analysis (SCAL). This analysis provides information on the physical properties of the rocks in natural oil reservoirs, including its porosity, permeability, grain density and fluid saturation. With this information, our clients in the oil and gas industry can project a more accurate image of the wellsite and the range of resources that can be accessed and processed.

Understanding the properties of the rock is very important to the health of the entire extraction system. Without a basic understanding of the rock’s characteristics, clients not only risk hazards to their safety and damage to their machinery, but also risk the loss of valuable minerals and resources that interact with the rock to varying degrees.

Texas OilTech Laboratories, in partnership with our technical associates, provides a full suite of core analysis, complete with guidance regarding the potential productivity of the wellsite. As always, we are available for sampling, testing, and data analysis all within a timely and cost-effective manner.


Special Core Analysis

As part of Texas OilTech Laboratories’ core analysis package, we combine our efforts with our strategic partners to also include sampling and testing for special core projects and sites. Of particular importance to understanding the properties and parameters of special core projects are highlighted, but not limited to the following:

Capillary Pressure- the interactions of forces between the fluids and rock used to determine the pore throats and relate water saturation to permeability, porosity, and the height above the oil-water contact.

Relative Permeability- the ratio of effective permeability in a multiphase system.

Electrical Properties- properties used to help define the fluid distribution and aid of the calibration of electrical logs.

Wettability- the impact that fluid distribution has on properties such as capillary pressure and relative permeability.

Special Core Analysis not only allows us to expand on measurements found during routine analysis, but also allows us to simulate rock properties as they exist in the reservoir as extrapolated from data collected from representative samples. In addition to the measures listed above, Texas OilTech Laboratories is happy to provide miscible flood cleaning, humidity drying and critical point drying, ageing and sample saturation, formation factor and resistivity index, centrifuge analysis, high speed and overburden options, mercury injection porosimetry, and nuclear magnetic resonance (NMR).
