WebThe primary natural drive systems are water drive, solution-gas drive, gas-cap drive and gravity drive (Figure 1). Combination drive systems are common and are mixtures of two or more primary drive systems. Although another drive mechanism—rock compaction drive—is rare, it is an important factor in a few major fields around the world. jotter books clipart
