Percussion drilling, cable tool drilling

There are two main types of onshore drilling for natural gas. Percussion /cable tool drilling, consists of raising and dropping a heavy metal bit into the ground, effectively punching a hole down through the Earth. Cable tool drilling is usually used for shallow, low pressure formations. The second drilling method is known as rotary drilling, …

Permeability; Permeable; Permeability rate

The ability, or measurement of a rock’s ability, to transmit fluids, typically measured in darcies or millidarcies. Formations that transmit fluids readily, such as sandstones, are described as permeable and tend to have many large, well-connected pores. Impermeable formations, such as shales and siltstones, tend to be finer grained or of a mixed grain size, …

Open season procedures; Open season rules for LNG capacity; Open season processes

It is a method to ensure that all parties have open access use of an LNG terminal and it is thus a transparent capacity allocation mechanism. The allocation is made on a demand basis but users risk losing allocated capacity that has not been used (UIOLI) and thus creates a level playing field. An open …

Original oil in place

This is the total resource base without regard to recoverability; it is essentially geologic in nature. The oil recovery factor (expected ultimate recovery divided by original oil-in-place) indicates what percent of the total resource can be recovered. Ultimately, the actual percentage recovered is significantly driven by complex economic and technological considerations.

Ortophoto, ortophotograph, ortophoto map

An ortophoto map is an aerial photograph which by metrical features completely corresponds to the map of the same scale. The procedure for producing ortophoto maps is faster thus more cost-effective than classical or digital maps. The production of an ortophoto map is based on oriented digital photogrammetric image and digital relief model. Once made …
