Gemalto was an international digital security company providing software applications, secure personal devices such as smart cards and tokens, e-wallets and managed services. It was formed in June 2006 by the merger of two companies, Axalto and Gemplus International. Gemalto N.V.'s revenue in 2018 was €2.969 billion. [1]
Techlog is a Schlumberger owned Windows based software platform intended to aggregate all the wellbore information. It allows the user to interpret any log and core data. It addresses the need for a single platform able to support all the wellbore data and interpretation integration workflows, reducing the need for a multitude of highly specialized tools.
Schlumberger. Schlumberger NV ( French: [ʃlumbɛʁʒe, ʃlœ̃b-] ), doing business as SLB, also known as Schlumberger Limited, [2] is an American oilfield services company. [3] [4] As of 2022, it is both the world's largest offshore drilling company and the world's largest offshore drilling contractor by revenue.
A High Assurance Internet Protocol Encryptor ( HAIPE) is a Type 1 encryption device that complies with the National Security Agency 's HAIPE IS (formerly the HAIPIS, the High Assurance Internet Protocol Interoperability Specification). The cryptography used is Suite A and Suite B, also specified by the NSA as part of the Cryptographic ...
v. t. e. Spontaneous potential log, commonly called the self potential log or SP log, is a passive measurement taken by oil industry well loggers to characterise rock formation properties. The log works by measuring small electric potentials (measured in millivolts) between depths with in the borehole and a grounded electrode at the surface.
Since spontaneous potential is a measure of electrochemical potential and the ionic activity of a solution is inversely proportional to its resistivity, the above equation can be simplified as SP = E C = K log 10 (R mfe /R we), where R mfe and R we are equivalent mud filtrate resistivity and equivalent formation water resistivity respectively.
The Schlumberger brothers called this technique an "Electrical Survey", but the more common name "well log" was coined a few years later in the United States. At that time, Pechelbronn was the only oil field known in France. On 28 July 1928, the owners of the oil field signed a contract with the Schlumberger company to do
Pierre Schlumberger was born in 1914, the son of Marcel Schlumberger, a mechanical engineer, and his wife Jeanne Laurans. [1] Marcel co-founded Schlumberger in the 1920s with his brother, Conrad, a physicist. [1] Pierre was the brothers' only male heir.
