Geological drilling
Geological drilling is an important means for exploration of the earth. Due to the nonlinearity and coupling, geological drilling is accompanied by low efficiency and safety, and difficult to accurately predict the drilling states. Moreover, the vertical well trajectory needs to follow the plumb line. A novel optimization method is proposed to ...to validate a drilling cost model called Wellcost Lite, developed by Bill Livesay and coworkers. The model estimates the cost of a well of a specific depth, casing design, diameter, and geological environment. A series of basecase geothermal well designs was generated using the model, and costsof shearing. Geologic logs require the adequate description of materials; a detailed summary of drilling equipment, methods, samplers, and significant engineering conditions; and geologic interpretations. Complete geologic logs of drill holes require adequate descriptions of recovered surficial deposits and bedrock,
