Geological drilling
Geological principles state that if a fragment of rock is included, that is entirely surrounded by rock, it must be older than the surrounding rock. This is because it had to be present for the rock to form around it.Geological, technological and technical justification for choosing a design solution for drilling wells under different geological conditions V G Mukhametshin1, ... Drilling through a layer of permafrost, loose sandstones and unstable clay sediments requires solving the following main tasks: strengthening of well walls, reducing the …Drilling process characteristics and model methodology.

Dear Colleagues, Drilling and well completion processes are the key to the successful solution for both increasing world’s energy demand and energy transition, whether it is associated with exploration and extraction of oil, gas, geothermal energy, gas hydrates, deep mining, subsea mining, and/or underground storage of CO 2, …Using the combination of data and interpreted information allows visual and analytical processes to clarify the sub-surface environment as the drilling activities are happening and allows for more fine-grained control of these actions, resulting in a higher quality wellbore, drilling more effectively and with longer time in the pay zone.Geology plays an important role in the success or failure of a core-drilling program. Many times, due to lack of geological information, the designed drilling system – the drilling rig capacity, mud pump capacity, type of core barrels, selection of casing point, type of bits, selection and properties of drilling mud – and the operational drilling parameters – weight on bit (WOB ...
The 3.1- and 3.7-km-deep FFC-1 and DGE-1 geothermal explorations wells drilled into the Precambrian crystalline basement on the southern margin of the Fennoscandian Shield are evaluated regarding experiences from drilling, geological conditions, and thermal properties. Both wells penetrate an approximately 2-km-thick succession of sedimentary strata before entering the crystalline basement ...Percussion drilling operates by a drill bit repeatedly striking the rock face and crushed rocks are transported to surface through hole annulus or drill rods (Fig. 4.20). The drilling provides less geological information than diamond core drilling, but this is offset by significantly higher drilling speed and lower cost. ….
