As per the Israeli Gas Law, pressure of 4 bar or less.

Very low pressure are those sections of the distribution network that will work under maximum pressure of 75 to 150 millibar (bar – 1,000 millibar). These sections are expected to supply natural gas to certain suppliers or regions where it is not possible to lay polyethylene pipes (PE Mains) at a pressure of 4 to 7 bar.

These sections will receive gas from the low pressure network via DPRS (Direct Pressure Reduction Stations)

A tool string used for washover operations. The wash pipe is a relatively large internal-diameter tubular that can be washed over a fish in preparation for engaging and retrieving the fish

The recording of information about subsurface geologic formations, including records kept by the driller and records of mud and cutting analyses, core analysis, drill stem tests, and electric, acoustic, and radioactivity procedures. 

The fraction of water in a given pore space

An accessory used in fishing operations to go over the outside of tubing or drill pipe stuck in the hole because of cuttings, mud, and so forth, that have collected in the annulus. The washover pipe cleans the annular space and permits recovery of the pipe. It is sometimes called washpipe.

Well stimulation involves techniques to optimize well performance. This may include pumping of acids, energized fluids, and various other chemicals to improve formation flow characteristics.

The ratio of produced water to produced gas

Visualization of seismic surveys have been taken to a new level with the advent of virtual reality rooms, allowing 3D subsurface images to be displayed on large screens and to be viewed from almost any angle. Different development options, such as the impact of various drilling targets, can be simulated. Much of the benefit of this approach stems from the fact that communication and understanding are greatly enhanced when multi-discipline teams meet whilst “immersed” in such an environment.

The value at the mouth of the well. In general, the wellhead price is considered to be the sales price obtainable from a third party in an arm’s length transaction. Posted prices, requested prices, or prices as defined by lease agreements, contracts, or tax regulations should be used where applicable. Natural gas price may be measured at different stages of the supply chain and the first price is the wellhead price
