| valign="top" | - Generally limited to sandy soils. Soft clay will be penetrated only very slowly and coarse gravel and other highly permeable materials (cracks in the formation) cause loss of working water and cannot be drilled. The borehole stays open by water pressure. To prevent collapsing fluid-drilled boreholes must be kept full of water during the entire drilling and well installation process.通常仅限用于沙质土壤。虽然可以穿透软质黏土，但是速度非常慢，而且粗碎石等透水性强的物质（地质构造中的裂隙）会导致钻井用水流失因而无法钻井。由于有水压，探孔保持敞开。为了防止塌陷，液钻探孔在整个钻井和装井过程中必须保持满水状态。<br>
- A large amount of working water needs to be available on the drilling location (several 200 liter drums/hour). The drilling and well installation needs to be done on the same day. Leaving the borehole open during the night has a high risk of collapsing.钻井点需要大量的钻井用水（每小时几桶200升的水）。钻井和装井需要在同一天完成。如果留下探孔敞开过夜很可能有塌陷的风险。<br>
- The use of large quantities of water, the use of drilling fluids to greater depths and a motor pump make the equipment cost relatively high. 使用大量水、使用钻井液达到更深以及马达泵的运用使设备成本相对高昂。使用大量水、利用钻井液达到更深以及运用马达泵使设备成本相对高昂。<br>
