Core Lab offers the innovative evaluations needed to evaluate the most difficult reservoirs Core Lab was the first company to introduce laser optics particle size analysis as a commercial, routine service. With a range of measurement which covers sand, silt and clay size particles, the applications of the data have grown to include enhanced sidewall permeability determination, gravel pack design and capillary pressure simulation.

Percussion Sidewall Cores
Data provided by the analysis of percussion cores has been in use in the industry for more than half a century. The analysts at Core Laboratories are trained in methods of analysis, which will provide to the client a reliable, fast and accurate data set that can aid in completion decisions. Data normally provided include porosity (summation of fluids method), permeability (enhanced by Laser Particle Size Analysis), fluid saturations, description of probable production, sample quality index and lithological description. Digital photography, both white and ultra-violet, and Laser Particle Size Analysis are often added for a more complete evaluation. All data presentations are available in a digital format.

Rotary Sidewall Cores
Rotary tools have provided samples, which are suitable (subject to good recovery) for all tests, which can be provided on plug samples, drilled from a conventional core. Fluid saturations may be determined by either the Dean-Stark method or the summation of fluids technique. Porosity and permeability may be measured in a core holder, at stressed conditions, as with any conventional plug sample. The fact that one point may have to be chosen to represent many feet of reservoir rock makes this method of sampling less desirable than a full section of conventional core, but reliable data may certainly be acquired for the sample recovered. Rotary cores are most often quite suitable for more advanced testing when required.
