An automated drill rig (ADR) is an automated full-sized walking land-based drill rig that drills long lateral sections in horizontal wells for the oil and gas industry. [8] ADRs are agile rigs that can move from pad to pad to new well sites faster than other full-sized drilling rigs. Each rig costs about $25 million.
Well drilling can be done either manually or mechanically and the nature of required equipment varies from extremely simple and cheap to very sophisticated. Managed Pressure Drilling (MPD) is defined by the International Association of Drilling Contractors (IADC) as “an adaptive drilling process used to more precisely control the annular ...
the price of boring rises linearly with depth; bore axis with neutral floating; the possibility to make vertical or inclined bores up to 10 km deep; the possibility to make large diameter bores – even 5 times larger than on the ground compared to today drilling technologies; casing formed on site in the borehole
Seadrill is an offshore drilling contractor providing worldwide offshore drilling services to the oil and gas industry. Its primary business is the ownership and operation of drillships, semi-submersible rigs, and jack-up rigs for operations in shallow to ultra-deep water in both benign and harsh environments. It provides a contract-based ...
Directional boring machine. Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig.
Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking). This process is carried-out from a land surface, open pit floor, underground mine or floating vessel through pre ...
By the 1920s, about half of the company's drilling was outside the continental United States. Robert Longyear, Edmund's son, became president of the firm in 1924, preserving the chain of family ownership and management that would continue for another 40 years. In 1929, Longyear sold almost US$1.5 million worth of drilling equipment to other ...
A drilling rig is used to create a borehole or well (also called a wellbore) in the earth's sub-surface, for example in order to extract natural resources such as gas or oil. During such drilling, data is acquired from the drilling rig sensors for a range of purposes such as: decision-support to monitor and manage the smooth operation of ...
