Basin – or trough-shaped fold in rock in which rock layers are downwardly convex. The youngest rock layers form the core of the fold and outward from the core progressively older rocks occur. Synclines typically do not trap hydrocarbons because fluids tend to leak up the limbs of the fold. Opposite of anticline
A particular type of substation where energy is routed either from different sources or to different customers. Facility equipment used to tie together two or more electric circuits through switches. The switches are selectively arranged to permit a circuit to be disconnected or to change the electric connection between the circuits
In transporting gas from the production field to the end user, the demand fluctuates throughout the day, known as “diurnal swing”. The production field exports gas at a steady rate, but it is used variably throughout the day by customers (e.g. less during the night). Some of this swing capacity can be built into the production facilities and some can be provided by the national transmission system (all at a price of course).
Swing can be achieved by throttling the flowrate at a pressure reduction platform and thus using the flowlines from the field as storage. This is known as packing where rates into the flowlines exceed withdrawal rates, and then at times of high demand the pressure is allowed to fall which is known as drafting where rates into the pipeline are less than withdrawal
In other countries (besides Israel) gas is usually stored when demand is low in order to compensate for this, so that it can be used when demand is high.

Secondary seismic waves. A seismic wave with a direction of vibration that is perpendicular to the direction of travel. S-waves are slower than P-waves and travel only through solids
A “swath-sounding” sonar system is one that is used to measure the depth in a line extending outwards from the sonar transducer. Systems acquire data in a swath at right angles to the direction of motion of the transducer head. As the head moves forward, these profiles sweep out a ribbon-shaped surface of depth measurement, known as a swath. Current swath sounding systems utilize two different technologies to achieve bathymetry measurements across a “swath” of the sea floor: 1) Beam forming (multibeam echo sounders), and 2) interferometric or phase discrimination sonars. Both of these techniques have their merits, however the same end results are achieved
When companies swap quantities of gas, from different locations, or different development times.
