Ogaden attack The company was operating in 2007 in the volatile, predominantly Somali Ogaden region of Ethiopia in 2007. At the time the Ogaden National Liberation Front waged an insurgency against the Ethiopian government. The company and its employees suffered grievously as collateral damage in the war at 4:30 AM on April 24, 2007 when 200 ONLF militants attacked the company's camp in Abole, Somali Region. A firefight raged for 50 minutes between the attackers and 100 Ethiopian troops guarding the camp. The attack left 9 Chinese and 65 Ethiopians dead and 9 Chinese were taken as hostage. Projects *: The company was an early Chinese pioneer in performing geophysical surveying and drilling in Sudan. * Petronas, the Malaysian national oil company, contracted the company to conduct seismic survey in Ethiopia in Gambella an ...

Ogaden
Ogaden (pronounced and often spelled ''Ogadēn''; so, Ogaadeen, am, ውጋዴ/ውጋዴን) is one of the historical names given to the modern Somali Region, the territory comprising the eastern portion of Ethiopia formerly part of the Hararghe province. The other two names are the Haud and Reserved area. Etymology The origin of the term ''Ogaden'' is unknown, however it is usually attributed to the Somali clan of the same name, originally referring only to their land, and eventually expanding to encompass most parts of the modern Somali Region of Ethiopia. During the new region's founding conference, which was held in Dire Dawa in 1992, the naming of the region became a divisive issue, because almost 30 Somali clans live in the Somali Region of Ethiopia. The ONLF sought to name the region ‘Ogadenia’, whilst the non-Ogadeni Somali clans who live in the same region opposed this move. As noted by Abdul Majid Hussein, the naming of the region where there are several Somal ...

Drilling Rig Operators
Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is drilled. In rock drilling, the hole is usually not made through a circular cutting motion, though the bit is usually rotated. Instead, the hole is usually made by hammering a drill bit into the hole with quickly repeated short movements. The hammering action can be performed from outside the hole ( top-hammer drill) or within the hole (down-the-hole drill, DTH). Drills used for horizontal drilling are called drifter drills. In rare cases, specially-shaped bits are used to cut holes of non-circular cross-section; a square cross-section is possible. Process Drilled holes are char ...

Oilfield Services Companies
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust. Petroleum reservoirs are broadly classified as ''conventional'' and '' unconventional'' reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability, while in unconventional reservoirs, the rocks have high porosity and low permeability, which keeps the hydrocarbons trapped in place, therefore not requiring a cap rock. Reservoirs are found using hydrocarbon exploration methods. Oil field An oil field is an area of accumulation of liquid oil underground in multiple (potentially linked) reservoirs, trapped as it rises by impermeable rock formations. In industrial terms, an o ...

Engineering Companies Of China
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific ...
