Fifteen years ago the best drillers could force a well-shaft into a gentle arc. These days shafts can be drilled vertically to a depth of several kilometres--then made to turn sharply and continue horizontally for up to 12km (or 7 miles). Will Grace of Schlumberger, an oilfield services company, likens it to dropping a plumb-line from the top of the Empire State Building and then guiding it through the rear and front windscreens of every car parked in the nearby streets. Such technology vastly increases the area one rig can cover. Oilfield services (OFS) firms such as Schlumberger are the unsung workhorses of the oil industry. They do most of the heavy lifting involved in finding and extracting oil and gas. They are far less well-known than the oil firms that hire them, but immensely lucrative. Schlumberger's success highlights a shift in the balance of power between oil companies and their flunkeys. Until the 1990s OFS companies were far smaller and earned low margins on straightforward tasks, such as drilling vertical wells. That has changed dramatically.
