Core Analysis

POROLABS specializes in the characterization of porosity and pore throats, mineralogy, and the organic richness for oil and gas reservoirs.

POROLABS has the experience, technology and testing methodology internally to provide clients various core data characteristics with rapid turnaround time.  POROLABS is experienced in providing Mercury Injection Capillary Pressure (MICP), Total Organic Carbon (TOC) analysis, and X-Ray Diffraction (XRD) analysis.

Sample Preparation

POROLABS takes a tailored systematic approach to each of its services in order to optimize and develop the best analytical program based on sample type as well as individual clientele needs.  These include, but are not limited to, the following:

  • Crushing and Sieving
  • Photos
  • Plug Acquisition
  • Soxhlet Cleaning

Special Core Analysis

Mercury Intrusion Capillary Pressure (MICP) Analysis

MICP analysis provides an accurate and consistent methodology for determining various petrophysical rock properties of a sample.

Mercury Intrusion Analysis

Yields pore volume distribution of pore sizes between 140 and 0.004 micrometers in diameter.  Data provided also includes calculations of:

  • Bulk and grain density
  • Pore Throat Distribution
  • Porosity
  • Wetting Phase Saturation @ HAFW
  • Swanson Permeability

If requested, Air-Brine and Oil-Brine Pc curves, cumulative intrusion, normalized pore volume distribution, wetting phase saturations and J-Functions can be provided.

Mercury Intrusion and Extrusion Analysis

Yields the aforementioned intrusion analysis plus extrusion data as the pressure decreases to atmospheric pressure.

Geochemical Analysis

The maturity of a rock, as well as its potential to generate oil and/or gas can be evaluated by TOC and Rock Eval pyrolysis or Source Rock (SR) analysis.  Various ratios from the data provided by these analyses aid in the interpretation of rock characteristics.

Vitrinite Reflectance

Source rock maturity indicator

Rock Evaluation

S1, S2, S3, Hydrogen Index (HI), Oxygen Index (OI), Production Index (PI), Normalized Oil Contact (NOI), Tmax

TOC Analysis

Organic Richness

Petrographic Analysis

These analyses provide clients with the rock properties that influence the effects on reservoir quality, depositional environment, diagenetic history, formation damage prevention and anomalous wireline log response.

Scanning Electron Microscopy (SEM)

Provides documentation of three-dimensional pore geometry and authigenic components.

X-Ray Powder Diffraction (XRD) Analysis

Provides data used to determine the rock composition and the abundance of clay minerals of a rock sample.  Yields weight percent and volume percent of specific minerals present in the rock sample.

  • Bulk Mineralogy
  • Bulk and Detailed Clay Mineralogy

X-Ray Fluorescence (XRF) Analysis

Provides data quickly to identify the characteristics and composition of the rock and confirm the mineralogy of the strata. Measuring the elements within the drill cuttings to determine properties of quartz, limestone, clay and other properties can determine where the laterals are located within the strata, thus identifying what part of the lateral to complete.

XRF Benefits:

  • Quick and affordable approach to measure cuttings, core and outcrops of host rocks.
  • Analyze reservoir rock composition and lateral well sections(cuttings).
  • No logs in lateral required.
  • Insight provided for proper frac spacing.
  • Target/determine where the well is within the section.

Thin Section Descriptions (THS)

Provides a description of lithology, texture, grain size, porosity types, detrital mineralogy, authigenic components, and reservoir quality.

  • General Thin Section Description: Qualitative description of lithology, texture, grain size, detrital mineralogy, authegenic components, porosity types, reservoir quaility, formation damage. Two Photomicrographs.

  • Detailed Thin Section Composition Analysis: Description of lithology, texture, grain size, reservoir quality,formation damage. Modal analysis/point count (250 pts.) gives quantitative detrital mineraology, authegenic components, and porosity types.  Two Photomicrographs.
