Why is well design performed?

Well design is performed to ensure the efficient and safe drilling and operation of wells, in particular for the production of water, oil, gas, as well as for geotechnical and environmental studies. The main objectives of well design include:
Optimization of the drilling process – determining the most effective drilling methods, selecting appropriate equipment, well parameters to achieve the required results at minimal cost.
Preventing accidents and reducing the risks – design must take into account geological conditions in order to avoid problems such as well wall collapse, fluid leakage, explosions or other hazards.
Ensuring operational efficiency – proper design helps maximize well productivity and extend its service life.
Assessing and reducing environmental impact – design includes measures aimed at reduction of negative impacts on the environment, in particular on water resources and ecosystems.
Well technology and design selection – selection of appropriate materials and design solutions to ensure the stability of the well and its long-term operation.
Well design is a critical stage for ensuring the economic efficiency and safety of the well during its drilling and operation.

What are the stages of well design?

Well design usually includes several stages, each of which has its own specific tasks and objectives. The main stages of well design are the following:

1. Preliminary research and preparation:
– assessment of the geological conditions of the site.
– study of available geophysical, geochemical and geological data.
– determination of the purpose of the well (for example, water intake, mineral extraction, oil and gas operations).

2. Geological survey:
– conducting geological exploration (drilling exploratory wells, analysis of rock samples).
– assessment of the subsoil structure and selection of the best point for drilling.
– well design:
– determination of well depth, diameters, configuration.

3. Selection of materials for well construction (pipes, casing, cement).
– risk assessment and selection of drilling methods depending on geological conditions.

4. Development of drilling technology:
– preparation of a detailed drilling plan, selection of equipment and tools.
– development of safety measures, environmental protection and reduction of impact on the ecosystem.

5. Monitoring and control during drilling:
– control of the drilling process to ensure safety and quality of work.
– correction of parameters in case of changes in geological conditions.

6. Completion and interpretation of results:
– completion of drilling and interpretation of the data obtained (samples, geophysical data).
– assessment of the possibility of well operation and testing.

7. Selection and design of equipment for well operation:
– preparation of a plan for further well operation (installation of pumps, resource collection systems, etc.).

The above-mentioned stages are basic, there may be additional tasks or stages depending on the type of well and the specifics of the project.
