Telega Tunggal No 1 was the first successful oil well in Indonesia, drilled in 1885 in Sumatra. The area where the drilling occurred was known as the Telega Said concession area. The drilling in Sumatra had begun earlier and Telega Tiga is usually cited as the first exploratory well in 1883. [1] [2]
Static level is the level of water in the well when no water is being removed from the well by pumping. [8] Water table is the upper level of the zone of saturation, an underground surface in which the soil or rock is permanently saturated with water. [9] Well yield is the volume of water per unit time that is produced by the well from pumping. [8]
A dug well in a village in Faryab Province, Afghanistan The difference between a well and a cistern is in the source of the water: a cistern collects rainwater whereas a well draws from groundwater. A well is an excavation or structure created on the earth by digging, driving, or drilling to access liquid resources, usually water.
Reservoir engineers could use the map as a part of their well drill planning. Reservoir engineering is a branch of petroleum engineering that applies scientific principles to the fluid flow through a porous medium during the development and production of oil and gas reservoirs so as to obtain a high economic recovery.
Well X has a measured depth of 9,800 ft and a true vertical depth of 9,800 ft while well Y has measured depth of 10,380 ft while its true vertical depth is 9,800 ft. To calculate the hydrostatic pressure of the bottom hole, the true vertical depth is used because gravity acts (pulls) vertically down the hole.
Indonesia's main railways, operated by Kereta Api Indonesia and its subsidiaries, is used for both passenger and freight transport. The majority of railways is located on Java . There are four separate railway networks on Sumatra : one in Aceh , one in North Sumatra (Aceh connection proposed to be finished in 2020s), another in West Sumatra ...
Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole.The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs).
The mud viscosity and gel strength are important properties, as cuttings will settle to the bottom of the well if the viscosity is too low. Fly ash absorbent for fluids in mud pits. Other properties include: Most drilling muds are thixotropic (viscosity increases when static). This characteristic keeps the cuttings suspended when the mud is not ...
