    Abstract: The continuous importation of foreign bentonite in the presence of proved and potential clay deposits spread across states in the country is not consistent with the government desire and commitment for the development of local content. This research explores the possibility of improving the Umuna local clay samples for the production of drilling mu... Show More

    Abstract: Millions of dollars associated with importation cost has and is still been spent by oil companies carrying out drilling operations in Nigeria, and this if allow to continue unchecked, does not align with the country policy of promoting local content in the oil and gas industry. This study experimentally evaluates the suitability of local eggshell a... Show More

    Abstract: S-wave source vector exploration is a promising technology in future seismic exploration. Conventional P-wave and S-wave joint inversion methods for hydrocarbon detection are limited in some aspects. First, P-wave and S-wave joint inversion is mainly based on the converted wave theory, but no theoretical support for S-wave generated by S-wave sourc... Show More
