Enhanced Micro-bubble Drilling Fluids System
Enhanced Micro-Bubble Drilling Fluids — a better solution of drilling fluids for Underbalanced Drilling, Reservoir Protection & Leakage Prevention
The enhanced micro-bubble drilling fluids system is the ideal solutions of Underbalanced Drilling (UBD), development of low pressure reservoir and protection of oil formation to increase future oil recovery rate, due to its ultra-strong wall of the micro-bubble in the drilling fluids, which is totally different with the conventional micro-bubble drilling fluids.
Picture of the micro-bubble
a. Reduces the difficulty, the cost and the risk of well control in underbalanced drilling.
b. Greatly reduces the drilling fluids cost of underbalanced drilling
c. Protect oil/gas formation.
d. Increase overall oil recovery rate.
e. Environment friendly, easy to dispose. No pollution.
a) Strong anti-leaking property, be effective in high pressure formation.
b) No additional equipment needed;
c) Good in carrying rock debris;
d) High anti-pollution property;
