The study examined the effects of Working Capital Management(WCM) on firms performance in oil
and gas industry in Nigeria, for the period of 2011-2020. The study adopted judgemental sampling
techniques, a sample of ten (10) companies in the oil and gas industry in Nigerian.Data were
sourced from their annual report and accounts. Descriptive statistics, correlation, panel unit
root,Pedroniccointegration test were employed and the multiple regression analysis of the (E-VIEW
9.0) at 0.05 level of significant (95% confidential interval) was used as a basis of testing the
hypotheses. The findings revealed that Account Payable Period (APP) and Account Receivable
(ARP) have significant effect on Return on Asset (ROA) while Cash Conversion Cycle (CCC) and
Inventory Collection Period (ICP) does not have significant effect on ROA. The study concluded
that WCM has a significant effect on firm’s performance in the Nigeria oil and gas industry. The
study recommends that the average number of days that is used by the firms to convert its
inventories to cash should be reduced because major source of working capital financing for firms
should be repositioned in order to reduce the CCC from its present insignificant status to a
significant one.
