Message from the Executive Team 2013 – A RECORD YEAR Core Laboratories’ 5,000 worldwide employees produced another record year as oil  companies utilized Core’s newest technologies to maximize their daily production  of crude oil and natural gas while optimizing estimated ultimate recovery (EUR) of  hydrocarbons from their aging fields. Core’s continued focus on our three long-term  growth strategies, underpinned by operational excellence, enabled Core to outpace  almost all other oilfield service companies in earnings growth, rate of free cash  generation, and return on invested capital. The Company’s laser focus on crude-oil developments, especially those in the  deepwater and unconventional tight-oil plays that are primarily in shale reservoirs,  continue to serve our shareholders well, as over 80% of Core’s revenue is now  derived from oil-related projects. This percentage is likely to continue to grow as  development of unconventional tight-oil shale reservoirs gains traction, not only in  North America, but in the United Kingdom, Russia, North Africa, the Middle East,  China, and Australia, among other places. In North America, an energy industry renaissance is underway, spearheaded by the  emergence of technologies applied to horizontal wells. Currently, approximately two  of every three wells drilled in the United States — some 24,000 wells in 2013  alone — were drilled horizontally through the reservoir. Typically, a vertical well is  drilled down to the reservoir, and then rotary steering technology allows the well- bore to penetrate thousands of feet of reservoir rock horizontally. The horizontal  section, or lateral, can be as long as  10,000 feet in length, through primarily  shale rock. Shales are typically non-  porous and non-permeable rocks, unlike  the porous and permeable sandstones  and carbonates in conventional reser- voirs. To initiate hydrocarbon flow from  shales, extensive hydraulic fracturing  operations are conducted in up to 30 zones, or stages, in the lateral. The leading unconventional tight-oil  plays in the United States include the  Bakken, Eagle Ford, and several zones  in the Permian Basin. U.S. production  of crude oil, condensates, and natural
