Demshur also confirmed the Spraberry/Wolfcamp oil shale formations are now the world's second largest oil field, trailing only to that of Saudi Arabia. Using new horizontal drilling techniques and hydraulic fracturing, Demshur said these areas will be very exciting for decades to come. When asked about the company's technology, Demshur explained that Core Labs helps analyze rocks to determine not only where the oil and gas are but how best to recover that oil. The company can also analyze each stage of fracturing to determine whether the process is working to its highest potential. Cramer said that no other company merges oil, technology, engineering and great science like Core Labs.
