Once the cement hardens, continue drilling into the next formation (if necessary). Known world oil reserves are concentrated in a relatively small number of giant and supergiant fields in a few sedimentary basins. Because of the diverse objectives of their supporting governments, NOCs pursue goals that are not necessarily market oriented. No other basin has more than one such field. They have to be transported to an oil refinery. Transport of the crude oil to the refinery is sometimes very complicated.

Located on the Persian Gulf nestled in beside Iraq and Saudi Arabia, Kuwait has oil reserves that, along with gas, account for about 92% of its export revenue. Giant and supergiant petroleum fields and significant petroleum-producing basins of sedimentary rock are closely associated. The pressure from the mud will then force the plug (and cement) down into the casing to where the cement is forced into the space between the surface of the well and the walls of the bore hole. The chemically stored solar energy is whittled away by the long and intricate process of petroleum formation. The amounts of porphyrins found in crude oils vary from traces to 0.04% (or 400 parts per million).10 Experiments have produced a concentration of 0.5% porphyrin (of the type found in crude oils) from plant material in just one day,11 so it doesn’t take millions of years to produce the small amounts of porphyrins found in crude oils. Although these companies are driven by commercial concerns, they may also take into account their nations' goals when making investment or other strategic decisions.
