Synthetic layered structures have been investigated using a 1.3 GHz Ground Penetrating Radar (GPR) system. Scaled reservoir model...

..., a mud is formulated using commercial primary emulsifier. Mud properties such as density, rheology, API and HPHT filtration control tests have been conducted for fresh mud and for muds hot-rolled at 300degF and 500psi for 16h. It is observed from the laboratory experiments that the mud samples formulated...
