Sammendrag
Sodium formate and Potassium formate-based drill-in fluids were designed and characterized at the UIS lab. Moreover, Cesium/Potassium- based drill-in fluids were formulated and characterized its properties along with its hydraulic fracturing performance. Some of the main results are summarized as follows:
- At different micron sized CaCO3 particle concentrations, the sodium and potassium fluids performed thermal stable rheology properties until 80 degrees celcius.
- CaCO3 nanoparticles improve the particle stability and thermal stability in potassium and sodium formate fluid systems formulated with micron sized CaCO3
- The cesium/potassium base mud exhibited a self-healing seal effect after the well was fractured.
- Addition of 2wt% micron sized quartz LCM particles in the cesium/potassium base mud, increased the fracturing and re-fracturing pressures by 6.5% and 5.4% respectively.
