Water security under pressure
L&T faced a familiar challenge: agricultural and industrial demand was outpacing the productivity of existing wells in Al-Qassim and Hail, but new boreholes were being drilled with unacceptably high dry-hole rates. Desktop interpretation of regional geology was no longer sufficient.
Resistivity contrast at depth
TDEM surveys at 200 m line spacing built 3D resistivity models penetrating to 400 m+. Where TDEM identified high-priority targets, follow-up GPR provided shallow-aquifer detail. Both datasets were co-registered and inverted using full-waveform algorithms calibrated against existing well logs.
Zero dry-hole encounters
Seven productive aquifer zones were delineated with depth-to-water estimates, expected yield, and recommended drill coordinates. The follow-up drilling campaign confirmed all seven targets — a complete elimination of dry-hole risk versus the regional baseline of 30-40% dry-hole rates.
