Depends on the oil field. They've learned how to do it right. Most will because it is cheaper. The only ones that won't are the government controlled ones because hey answer to no one....
My second experience was of the Kutubu oil field, operated by a subsidiary of the large international oil company Chevron Corporation and located in the Kikori River watershed of Papua New Guinea.1 The environment in the watershed is sensitive and difficult to work in because of frequent landslides, much limestone karst terrain, and one of the highest recorded rainfalls in the world (on the average, 1,092 cm per year and up to 36 cm per day). In 1993, Chevron engaged the World Wildlife Fund (WWF) to prepare a large-scale integrated conservation and development project for the whole watershed. From 1998 to 2003, I made four visits of one month each to the oil fields and watershed as a consultant to WWF. I was allowed freedom to travel throughout the area in a WWF vehicle and to interview Chevron employees privately.
As my airplane flight from Papua New Guinea’s capital of Port Moresby droned on toward the field’s main airstrip at Moro, I looked out the airplane window for some signs of the oil field infrastructure that I expected to see looming up. I became increasingly puzzled still to be seeing only an uninterrupted expanse of rainforest stretching between the horizons. Finally, I spotted a road, but it was only a thin cleared line about 9 meters broad through the rainforest, in many places overhung with trees growing on either side—a birdwatcher’s dream.
