Routine Core Analysis

Assess core permeability, porosity, fluid saturations, and other important reservoir properties

Rock and fluid samples provide a direct link to your reservoir or source rock. Our laboratory analyses can help you ascertain the depositional environment, quantify reservoir quality, and improve reservoir modeling for more accurate reserves estimates. With decades of skill and expertise spread across the globe, Weatherford Laboratories provides accurate core analysis for characterizing reservoir properties.

Core Preparation

Prepare core samples for a quality evaluation

Properly prepared slabs, plugs, and sub-samples are essential for accurate analysis. We use proven sample preparation and preservation techniques to provide quality material for laboratory analysis.

Core photography

Create high-quality visual records of your core samples

Our photographs provide a long-term record of core condition and hydrocarbon content. They also play a critical role in determining subsequent testing of the cores.

Fluid saturations

Obtain fluid-saturation values for your core samples

Accurate fluid saturations are essential to reserves evaluation. We obtain pore fluid saturations of core plug and full-diameter cores using the Dean-Stark toluene extraction method.

Fluid saturations

Permeability and porosity

Measure porosity, horizontal permeability, and vertical permeability

Grain density, porosity, and permeability measurements from actual rock are useful for calibrating log responses. We can measure these properties on core plugs, rotary sidewall cores, and full-diameter core samples.

Shale rock properties

Determine fundamental core data in shale samples

Pore connectivity and pathways in shales can skew the petrophysical measurements of your core samples. By crushing the sample, our in-depth laboratory analyses can deliver accurate shale properties.

Laser particle size analysis

Accurately determine grain size in rock samples

Sand screen selection relies on particle size assessment. Using laser particle size analysis, we can measure particles from 0.02 to 2,000 µm to help determine the optimal sand screen selection.

Isotherms

Determine gas storage capacity in shale samples

Isotherms help geoscientists quantify adsorbed gas storage capacity of a rock. This value is used with other measurements to calculate gas-in-place volumes and can be correlated with total organic carbon.
