Water Well Screen and Casing Selection: How Borehole Geology Determines Slot Size and Material Spec
Screen slot by D70 rule (0.25-2.0mm). PVC/SS316L/FRP by Cl & depth. 3 failure cases, repair 40-70% of well cost.

Southeast Asia Water Well Case Study: Drilling in Volcanic Tuff and Basalt in Java and Sulawesi
Java-Sulawesi: 20 wells. PDC in tuff (6.2 m/hr); DTH in basalt lifts ROP 229% (0.7→2.3 m/hr). Dual-method cuts cost/m 45% & NPT 65%.

Water Well Drilling in Fractured Limestone: How to Prevent Lost Circulation Without Stopping the Bit
Jordan/Lebanon fractured limestone: 3 signals warn of loss zones 0.5–1.5m early. Targeted LCM + 30–40% pump/RPM cuts retain 89% ROP, slash NPT 91%, mud cost 77%.

Jordan carbonates, Saudi sands, Iraq evaporites: 1,200km, 3 specs. Non-planar PDC (impact), planar PDC (abrasion), KCl mud (gypsum)—no single setup fits all.

Diesel-hybrid compressors alternate between diesel mode (18–25 bar, full ROP) and battery mode (10–14 bar, reduced ROP) — never running both simultaneously.
Jun 30,2026
Staged bit strategy — PDC (20° back-rake) for tuff, DTH (parabolic inserts, 10% Co) for basalt — delivered 3.3× ROP in basalt and 37% lower cost per metre across 20 Java-Sulawesi wells.
