Rotary Sidewall Core Samples


Rotary sidewall coring (RSWC) enables collecting numerous core samples easily and inexpensively in a single run. A wide range of analyses can be conducted on these samples, and the added value of knowing the exact depth at which a sample was taken makes RSWC samples a good alternative to a conventional core. Formation thickness and the number of target zones will help you determine whether rotary sidewall cores, a conventional core, or a combination of each will be the best option to evaluate the formation(s).  

Weatherford Laboratories offers full field handling and stabilization services for RSWC samples. Like a conventional core, the samples are most vulnerable as soon as they reach the surface. Proper identification, removal, and preservation are vital to ensure the reliability of subsequent analyses.  

RSWC Analysis

A full suite of analyses can be performed on rotary sidewall cores. The samples are cylindrical and allow for porosity and steady-state permeability measurements at net confining stresses. The samples are typically large enough to enable a myriad of additional testing, including fluid saturations, geochemistry, mineralogy and petrography, and special core analysis.  


Weatherford Laboratories also has the most experience in analyzing sidewall cores retrieved by the pressure rotary sidewall core system.  The analysis process has been developed internally using customized equipment designed to properly measure the collected gas, fluids, and rock.  

Sidewall cores enable precise depth control to investigate the petrographic and petrophysical details of your reservoir, ultimately giving you the confidence to make informed completion decisions.
