horizontal well

A horizontal well is an oil or gas well that is drilled vertically into the ground and then gradually curves to run sideways through underground rock formations. This technique allows access to a larger area of the resource-rich rock, increasing the amount of oil or gas that can be extracted from a single well. Horizontal wells are particularly useful when the underground deposits are spread out horizontally or trapped in tight formations, making extraction more efficient and cost-effective compared to traditional vertical drilling.
