Air Core Drilling Market – Global Industry Analysis, Growth, Share, Size, Trends, And Forecast 2019 – 2026
The global air core drilling market value is anticipated to exceed USD 1.45 billion by 2025, and is estimated to grow at a CAGR of 5.4% during 2020-2026.
The industry is expected to witness substantial growth over the next nine years owing to rising demand for efficient extraction techniques used in oil & gas wells and mines. The regolith drilling process involves compressed air sent to the bit for pulling up the cuttings to the surface where the samples are collected for a detailed study and thus provides comprehensive extractions data.
Other forms are rotary air blast, reverse circulation (RC) and open hole compression techniques which are used for mineral exploration depending on the sample requirements. Owing to its cost effective extraction and collection of cuttings, it can be combined with auger, cable tool, and percussion type drilling for various types of rock beds.

Unlike the conventional rigs where the contaminated samples need further filtration and processing, this technique provides clear sample recovery without hindering the rock penetration work. Additional benefits of this technique include continuous sample returns, instant switch between complimentary drill bits and reduced times in moving between boreholes is expected to maintain the ore grade of the mineral samples.
Air core drilling process is preferred for providing drilled cuttings faster, incurring minimal sample damages but is limited to mature geographical areas devoid of water and hydrogen sulfide zones. Concern over the health issues caused due to long exposure to metal dust, noise, and other toxic materials; there is a continuous revision of disease control and industrial safety standards.
