Drilling engineering history.
Oil well drilling is one of the most important branches of petroleum industry. Drilling is
widely used in exploration for oil and natural gas in the early stage of a search for oil. When a
seismograph surveying method is used to discover geological structure favorable for oil and gas accumulation, it is necessary to drill shallow to make explorations.
There are many indirect methods of prospecting for oil and natural gas, but such methods
indicate that certain possibilities exist for oil gas accumulation. These methods cannot prove
presence of oil in favorable area. They give no possibility for estimation of deposit that is
supposed to be discovered.
Drilling a well is the only method to find oil or gas and to prove communicability
(profitability) of the deposit discovered.
After discovering oil of gas, it is necessary to extract them from the deep underground to
make them available for further processing and consumption. As oil is usually accumulated
rather deep strata the most economical method of extracting it is to drill bore holes that can
serve as conduits for oil from the oil trap to the surface.
Wells are drilled for not only extracting oil but also for the purpose of injecting water, gas ,
steam, into the oil bearing strata to maintain formation pressure ,to apply secondary recovery
methods etc..
Drilling boreholes is used not only in the petroleum industry. Wells are drilled for many other
purposes like water supply, ores and coals exploration etc. However, oil and gas well drilling is the most advanced out of all the drilling industries because it deals with the deepest wells and the most save underground conditions.
The “Colonel Drake well” drilled in the united states by Colonel Edwin L. Drake in 1859, is
considered by many to be the first commercial well drilled and completed.
Through 1956, the cumulative world crude oil production was 95 billion bbl, of which 55
billion had been produced in the USA.
In the late 1990, the USA is still the world’s largest oil consumer both terms of shear
volume (18.2 MMbbl/d).
The USA is also the largest petroleum importer (9.5 MM bbl/d, representing over
50% of consumption). Worldwide production is about 62 million bbl/d. the bulk of
petroleum reserves is clearly outside the industrialized world of north America and
western Europe (combined 57 billion bbl vs. 1.1 trillion bbl worldwide).
The majority of petroleum is found in the Middle East, where 600 billion bbl are
produced, 260 billion of which are from Saudi Arabia alone.
In the USA and Canada approximately 34,000 wells were drilled during 1995 and
1996, representing almost 60% of all wells drilled worldwide (about 58,000). Yet the
United States and Canada, combined, account for only 13% of the world’s petroleum
production

Drilling engineering has a great history. It not comes in a day. A lot of people still now working for updating the technology. first liberty energy is one kind of that organization.
