  7. Drilling fluid - Wikipedia

    en.wikipedia.org/wiki/Drilling_fluid

    In geotechnical engineering, drilling fluid, also known as drilling mud, is used to aid the drilling of boreholes into the earth. Used while drilling oil and natural gas wells and on exploration drilling rigs , drilling fluids are also used for much simpler boreholes, such as water wells .

  8. Offshore geotechnical engineering - Wikipedia

    en.wikipedia.org/wiki/Offshore_geotechnical...

    Offshore geotechnical engineering is a sub-field of geotechnical engineering. It is concerned with foundation design, construction, maintenance and decommissioning for human-made structures in the sea. [1] Oil platforms, artificial islands and submarine pipelines are examples of such structures. The seabed has to be able to withstand the weight ...

  9. Cone penetration test - Wikipedia

    en.wikipedia.org/wiki/Cone_penetration_test

    The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils.
