Oil and gas services earnings kicked off today with Schlumberger (SLB 0.53%) releasing some growth on the top line that didn't trickle all of the way down to earnings. Within the earnings conference call, management touted international growth as the main driver of the company's success during the quarter. Because Schlumberger derives a much greater portion of its revenues from international markets when compared to peers like Halliburton (HAL -0.34%), this growth was great news for investors. Where did this growth take place? Motley Fool energy analyst Taylor Muckerman walks you through the report.
