Abstract

The temperate world such American and Canada are extensively increasing environmental legislations against oil-based muds and increasing exploratory activities in the offshore, it imperative to develop an oil based drilling muds that have resistance to the weather and relatively stable rheological properties at low temperature of -5oC to 20oC. This study investigates the use of non-edible algae oil to formulate ethyl biodiesel as based fluid for drilling mud that can perform the same function as convectional oil based drilling fluid and as well comply with the HSE (Health, safety and environment) standard in the temperate region and offshore environment. Experimental tests were performed at temperature condition of -5oC to 20oC on the synthetic ethyl biodiesel oil based mud samples so as to evaluate the rheological properties of the drilling mud formulations. The synthetic oil based was obtained from offshore drilling company and was used as control experiment. The following tests were run on these muds including; viscosity pH, gel strength, density and filtration tests at varied temperature and constant pressure and toxicity test to determine their usability in the defined conditions.

          <jats:p>The global rate of suicide is alarming, and the prevalence in Africa, especially  Nigeria, is more worrisome. The causes of suicide have been evaluated from a different perspective; however, studies on the psychosocial dimension in Africa are limited. With the increasing rate of Suicide in Nigeria and the literature gap in the psychosocial dimensions, this study explored the psychosocial causes of Suicide in Nigeria through a qualitative approach. The southwestern states in Nigeria were considered in this study because of the accounted high rate of suicide. States such as Ogun, Ondo and Ekiti were considered in this study. A purposive sampling technique was used to select key informants consisting of police officials, and religious and opinion leaders. Four themes emanate from the thematic analysis – economic challenges, frustration, mental issues and family issues were found to be psychosocial antecedents of suicide in Nigeria. Promotion of psychic support and social cohesion has been suggested to reduce suicide.</jats:p>
