| Abstract | Sometimes when dilling is in progress, we have to deal with high pressure and high temperature. It happened specially when the target is deep enough or geothermal well. HpHT condition will be able to effect the performance of drilling fluids by altering its rheological characteristics. We are able to measure the rheological at high pressure up to 3000 psig and high temperature up to 200 o C by Fann Model 70. Research was done with various additive, such as chemtroll -X, CMC LV, Polyplus and Ligco, with have objective to repair mud rheological at HPHT. Based on thi research by API recommended on pound per barrel (ppb). Result of this research are the composition is 2-3 ppb additive to be added on water based mud and stable rheological up to 200o C. |
