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.
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]
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.
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
Density logging is a well logging tool that can provide a continuous record of a formation's bulk density along the length of a borehole. In geology, bulk density is a function of the density of the minerals forming a rock (i.e. matrix) and the fluid enclosed in the pore spaces. This is one of three well logging tools that are commonly used to ...
Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs ...
Logging while drilling (LWD) is a technique of conveying well logging tools into the well borehole downhole as part of the bottom hole assembly (BHA).. Although the terms Measurement while drilling (MWD) and LWD are related, within the context of this section, the term MWD refers to directional-drilling measurements, e.g., for decision support for the smooth operation of the drilling, while ...
Rockwell Automation began in 1903 as the Compression Rheostat Launch Company. It was founded by Lynde Bradley and Dr. Stanton Allen with an initial investment of $1000. [2] In 1904, 19-year-old Harry Bradley joined his brother in the business. The company's first patented product was a carbon disc compression-type motor controller for ...
