For example, the invention of the “cluster well” drilling process made it possible to construct several shale wells on a single drilling platform. Since this drilling process can significantly reduce the handling time of drilling rig surface facilities, originally a single well was drilled on one platform and several wells can now be constructed, greatly improving drilling efficiency.
