Environmentally Friendly Fluid loss Control Agent in Water-Based Mud for Oil and Gas Drilling Operations

摘要

The fluid loss properties of mud formulated with concentrations of coconut shell and/or corncobs was studied. This study is focused on formulating water based drilling mud using corn cobs and coconut shell as additives in improving the performance of the mud. The additives were varied in different concentrations and its impact were evaluated on the filtration properties using low pressure low temperature (LPLT) filter press at 90°C and 100 psi. The result of the formulated mud with corn cobs and coconut shell additives were compared to that of the mud containing corn cobs alone, coconut shell alone, and without any of the additives. The results showed that the combination of corn cobs and coconut shell reveals a lower filtrate volume than individual coconut shell and corncobs. However, Corn cobs is a better fluid loss control agent than the coconut shell.
