Black Holes Black Holes. Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.

What is a Manhole? A manhole, or maintenance hole, is a tube which connects underground utilities to the surface. The tube is large enough to accommodate the body of a utility worker, and is covered with a top that is flush to the ground, and called a manhole cover.

What is a black hole? Space is a pretty dark place. Even so, some areas are darker than others. Nothing is darker than a black hole. A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives.

Groundwater This is the latest accepted revision, reviewed on 28 August 2017. Groundwater is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from, and eventually flows to, the surface naturally; natural discharge often occurs at springs and seeps, and ca

Black hole A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—including particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Blue hole A blue hole is a cave (inland) or underwater sinkhole. They are also called vertical caves. There are many different blue holes located around the world, typically in low-lying coastal regions. The best known examples can be found in Belize, the Bahamas, Guam, Australia (in the Great Barrier Reef), and Egypt (in the Red Sea).

Sinkhole A sinkhole, also known as a cenote, sink, sink-hole,[1] shakehole,[2] swallet, swallow hole, or doline (the different terms for sinkholes are often used interchangeably[3]), is a depression or hole in the ground caused by some form of collapse of the surface layer.

Measurement while drilling Is a system developed to perform drilling related measurements downhole and transmit information to the surface while drilling a well. MWD tools are conveyed downhole as part of bottom hole assembly (BHA). The tools are either contained inside a drill collar (sonde type) or are built into the collars themselves.

- For other uses, see Blue hole (disambiguation). A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock (limestone or coral reef). Blue holes typically contain tidally-influenced water of fresh, marine, or mixed chemistry.

- Horizontal directional drilling is an innovative trenchless technology that enables us to install underground utilities without conventional open trenching, as well as obtaining sub-surface information in areas previously inaccessible.Bores from 50mm (2) diameter to 900mm (36) diameter can be completed.irectional changes are made to the drilling alignment and direction with a bore head, which is offset slightly from the drill rods. Through small adjustments by the operator, steering corrections throughout the bore can be made (for example, around tree roots, boulders, buried utilities or private property).

Borehole 1 Borehole drilling: By at least the Han Dynasty (202 BC – 220 AD), the Chinese used deep borehole drilling for mining and other projects; Loewe states that borehole sites could reach as deep as 600 m (2000 ft).

- A sinkhole, also known as a cenote, sink, sink-hole, shakehole, swallet, swallow hole, or doline (the different terms for sinkholes are often used interchangeably), is a depression or hole in the ground caused by some form of collapse of the surface layer.s the rock dissolves, spaces and caverns develop underground. These sinkholes can be dramatic, because the surface land usually stays intact until there is not enough support. Then, a sudden collapse of the land surface can occur.

Directional boring Directional boring, commonly called horizontal directional drilling or HDD, is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area.rill stem sections are manufactured in 3.0 or 4.6 and also 9.1 meter lengths and have male threading on one end, and female on the other. It is common for a directional drill to carry as much as 305 m of rod on board. Drilling heads come in multiple designs and depends on the rock or soil being penetrated.

- There is a 9.1km borehole in Germany, part of the Continental Deep Drilling Project (KTB), but deeper still is the 12.25km Superdeep hole in the Kola Peninsula near the Arctic Circle in Russia, drilled between 1977 and 1989. The latter is roughly 0.4% of the distance (2,900km) to the core of the earth.

Tube well Borehole of a tube well, which is usually 30 metres (98 ft) deep or more. Outlet of a tube well to a temporary reservoir.A tube well is a type of water well in which a long 100–200 millimetres (3.9–7.9 in) wide stainless steel tube or pipe is bored into an underground aquifer. The lower end is fitted with a strainer, and a pump at the top lifts water for irrigation.orehole of a tube well, which is usually 30 metres (98 ft) deep or more.
