Drilling under Plan A will stop this weekend once the drillbit reaches 1, 247 feet (380 meters), then the drill will receive scheduled maintenance before resuming early next week, engineer Rene Aguilar said.
Inside the riser pipe is a space about half a meter in diameter, large enough to hold the spinning drill pipe and bit and to allow the return flow of drilling fluid.
Yet a survey of both the drill-bit manufacturers, which were Synthetic's immediate customers, and the drilling companies hinted that those projections were light.
