EcoDrill ® - Replacement of Oil Based Drill-in Fluids

Typical Properties and Field Applications

 EcoDrill is an effective Drill-in Fluids to replace OBM with the properties and application conditions below:

Temperature:
BHST 250‑356°F (121‑180°C)
Density:
1.20-1.80 SG
HTHP fluid loss:
2‑10 mL
Filter cake thickness:
0.5‑3 mm
Formation:
Hydrocarbon‑bearing and water sensitive formations
Base fluids:
Oil‑in‑water emulsion

Precautions and HSE Considerations

Emulsifier KDF010 plays important role for superior performance of EcoDrill by forming an efficient and stable emulsion at high temperatures. Some additives such as KDF041, KDF037, KDF047 are multi-functional. They not only effectively control the API and HTHP fluid loss of EcoDrill systems but also provide synergistic effect on shale stabilization together with KDF035 and base brines. Fluid loss control additives KDF027 and KDF037 are also effective in optimization of rheological properties of EcoDrill systems together with viscosifiers KDF001 and KDF011. The combination of oil-in-water emulsion and lubricant KDF004 improve the lubricity of EcoDrill systems significantly.
