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.
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).
A caliper log is a well logging tool that provides a continuous measurement of the size and shape of a borehole along its depth [1] and is commonly used in hydrocarbon exploration. The measurements that are recorded can be an important indicator of wash-outs, cave ins or shale swelling in the borehole, which can affect the results of other well ...
The SP log is therefore useful in detecting permeable beds and to estimate formation water salinity and formation clay content. Due to the nature of the electric current, SP can only be recorded in conductive mud. Determination of R w. As established earlier, static SP is defined as follow: SSP = −K log (R mfe /R we)
Cement bond log. A cement bond log documents the evaluation of the integrity of cement work performed on an oil well. [1] In the process of drilling and completing a well, cement is injected through the wellbore and rises up the annulus between the steel casing and the formation. [2]
