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 ...
WITSML is a standard for transmitting technical data between organisations in the petroleum industry. It continues to be developed by an Energistics facilitated Special Interest Group to develop XML standards for drilling, completions, and interventions data exchange. Organizations for which WITSML is targeted include energy companies, service ...
The Carpinteria Offshore Oil Field is an oil and gas field in Santa Barbara Channel, south of the city of Carpinteria in southern California in the United States. Discovered in 1964, and reaching peak production in 1969, it has produced over 106 million barrels of oil in its lifetime, and retains approximately 2 million barrels in reserve recoverable with present technology, according to the ...
The Dan field was discovered in May 1971 by the Britannia oil rig in Denmark Block 7.3 of the North Sea. [1] The reservoir is an Upper Cretaceous Danian chalk at a depth of 5,800 to 6,400 feet (1,768 to 1,951 metres). The oil has an API gravity of 30.4 and a gas oil ratio of 600 standard cubic feet per barrel (scf/bbl). The estimated ...
The Wellsite Information Transfer Specification (WITS) is a specification for the transfer of drilling rig-related data. This petroleum industry standard is recognized by a number of companies internationally and is supported by many hardware devices and software applications. [citation needed] WITS is a multi-layered specification:
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]
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 ...
