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 drilling; to make detailed records (or well log) of the geologic formations penetrated by a borehole; to generate operations statistics and performance benchmarks such that ...
Offshore drilling rig, c. 1968. The first semi-submersible resulted from an unexpected observation in 1961. [12] Blue Water Drilling Company owned and operated the four-column submersible Blue Water Rig No.1 in the Gulf of Mexico for Shell Oil Company. As the pontoons were not sufficiently buoyant to support the weight of the rig and its ...
Installations are identified by a large black-on-yellow sign on the installation. This may give the name of the original or current owner or operator, the field name, and a set of numbers and letters, e.g. Shell/Esso Leman 49/26A. The numbers identify the Quadrant and Block where the installation is located, e.g. 49/26 is in Quadrant 49 Block ...
The Lun-A (Lunskoye-A) platform, located off the north eastern coast of Sakhalin Island and is a concrete gravity base substructure (CGBS).. An oil platform (also called an oil rig, offshore platform, oil production platform, etc.) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed.
The rig was carrying approximately 280 tons of diesel, to power its generators, of which 53 tons is thought to have leaked into the sea, and dispersed or evaporated in rough conditions. [48] Environmental monitoring of plant and animal life is on-going, particularly in view of the economically important fish farming operations in nearby Loch Ròg .

The Sunshine Mining Co. made Washington state’s first oil discovery in July 1957, at a location 1.4 miles south down the coast from Ocean City. The discovery was on a state lease, and was below mean high tide, which made it an offshore well. [14] Additional wells were drilled in the area, but none produced any oil. [15]
Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the items listed below.
