The evaluation involved comparing the properties of the synthesized Lagenaria siceraria biodiesel and its drilling muds against those of the conventional diesel and some commonly used plant seed oil based biodiesels...

... Abstract The need to avoid environmental degradation caused by toxic chemicals during drilling fluid operations is one of the objectives of the oil and gas industry. In this work, a non-edible plant of Thevetia Peruviana oil was used as potential base oil for formulation of drilling mud...

... on the mud weight, yield point (Y.P.), and plastic viscosity (P.V.) of the formulated drilling mud. The additives’ effects were then recorded using a mud balance, a viscometer, and a heater for temperature variance. The results were then compared with the control mud to ascertain the additives’ effectiveness...

... Abstract This study attempts to show the effectiveness of using coconut fibre as a loss circulation material in drilling operation. The research incorporated a practical approach. Laboratory experiments was conducted to design drilling muds with the desired loss circulation materials...
