Conversion of heavy oil to light crude in the presence of a catalyst better known as catalytic upgrading of heavy and extra-heavy oil is been explored worldwide as one important in-situ upgrading technology among others. In this study, an equilibrated Fluid Catalytic Cracking (FCC) catalyst was sourced from a refinery, enhanced by the addition of transition metal ions, characterized using X-Ray Diffractometer (XRD), X-Ray Flourencence (XRF) and Fourier Transform - Infrared (FT-IR) techniques and tested in upgrading heavy crude oil. The enhanced FCC (Fluid Catalytic Cracking) commercial catalyst, hydrogen and glycerol were added into bitumen (32000cSt measured at 40oC) in a high-pressure batch reactor at 350oC for reaction time of two hours, pressure of 10bar and catalyst to bitumen ratio of 0.02. Viscosity reduction after thermal upgrade were 83 and 98% at room temperature and at 40oC respectively while the reduction after catalyst upgrade were 87.9 and 98.9% correspondingly under the same conditions. It was found that there was improved API gravity from 11.6 to 26.0 in thermal reaction and 30.5 in catalytic reaction. Other physiochemical properties of the bitumen investigated also improved significantly towards the production of lighter oil. The structural compositions of the bitumen before and after the reaction at 350oC were investigated using Fourier Transform - Infrared (FT-IR) and Gas Chromatograph – Mass Spectrometer (GC-MS). The result shows that the heavy molecular compounds like resins and asphaltene were broken down to lighter compounds. Keywords: Bitumen, Oilsand, Fluid Catalytic Cracking, Catalyst, Heavy oil, Upgrade.

Globally, water hyacinth infestations are regarded as invasive weeds which tend to obstruct water channel causing considerable socio-economic concerns, decline in biodiversity and water quality. The study seeks to ascertain the quantified mass and impacts of water hyacinth infestation along three designated waterways within the Nigerian coastline; Majidun River (MR), Igbokoda water channel (IWC) and Imo River (IR) (October, 2020 – April, 2021). This project was undertaken by NIMASA, saddled with the responsibility to clear waterways for safety of navigation and prevention of marine pollution. Reconnaissance survey was carried out using ARGIS mapping to identify infested hotspots. Mechanical and manual methods were deployed for evacuation, collection, weighing and documenting the dislodged vegetation for adequate disposal. The quantified water hyacinth evacuated recorded a total of 2,298 bags with weight of 92,449 kg (w/w) across 15 hotspots at Majidum River. At Igbokoda water channel, a total of 1,625 bags with weight of 122,500 kg (w/w) across 11 hotspots, while at Imo River, Ikot Abasi a total of 1,458 bags with weight of 56,055 kg (w/w) across 6 identified hotspots. The percentage total weight of infested water hyacinth had 34.11%, 45.20%, 20.68% and with no significant differences (p>0.05) across MR, IWC and IR respectively. The successful removal of the infested aquatic weeds could be effectively managed through routinely monitoring of the Nigerian aquatic ecosystems protected from immense anthropogenic pressure of constant of nutrients enrichment that could further proliferate the growth of these infested weeds. Keywords: Water hyacinth infestation, Mechanical removal, Nigerian coastal environment.

The drilling for oil and gas is at high risk and challenging for the past decades. Irrespective of the uncertainly and the problem associated with the drilling operations, wells are being drilled every day. In order to overcome these problems, the drilling mud engineers must prepare for these challenges so as to meet the expected revenue and the time allocated for a particular drilling job. In this work, experimental tests were conducted at temperature of 120oF and atmospheric pressure to determine the contaminants effects of mud system and drilling operation on seawater and cement slurry of water-based mud (WBM) and oil-based mud (OBM) properties respectively. However, results obtained from the salt and cement contaminants have shown that filtration of different agents into mud system affects the rheological and chemical properties of both (WBM) and (OBM) respectively. The presence of other contaminants on the drilling mud reduces the properties as well and in turn affects the rate of penetration, its performance and poses serious drilling problems. Based on the results obtained, it is advisable that mud program should be properly designed which gives provision for correction of expected contaminant(s) beforehand. Basic knowledge of the drilling mud chemistry must be known so as to effectively supervise the contaminants control, and also mud must be properly treated in order to prevent the destruction of subsurface equipment. Keywords: Drilling fluids, contaminants, water base mud, oil base mud.

Depot facilities are industrial equipments used for the storage of oil, gas and petrochemical products etc., and from which these products are usually transported to end users or for further storages. In the maintenance and sustainability of keeping fuel delivery systems in safe checks, there are needs to derive standard programs to achieving these objectives. Maintenance is a combination of technical and administrative activities to keep a machine or equipment in its functional state. Machines or equipment with poor maintenance will result in dysfunction that might likely result to defective products which affect the quality of the products. These involve reliability of the machines and equipments, the manpower and the equipment perform to a standard level of quality assurance. In this research work, the failure mode and effect analysis (FMEA) result indicate that six potential causes of failure were identified; three causes are critical and high risk priority number (RPN), these are; mechanical damage and cases of sabotage, spillage, potential fire/explosion. The above critical failures should be reduced and taking preventive action and corrective action to eliminate or reduce the failure. The result indicates that the equipment with the highest RPN 300 is pipe, which is that of mechanical damage and sabotage. But after implementing preventive and corrective action, the RPN has reduced to 160, when compared with Achilla, (2015). Keywords: Flow, pump, efficiency and reliability

Statistics is a branch of mathematics that articulates facts and figures for decision making after strategic analysis. When applied to core cultural values, statistics could help to arrange and streamline priority areas of relevance in an organization. Such streamlined priorities are normally defined in vision and mission statements of the organization and designed to be part of the work-culture and core values that defines reform processes. Statistics therefore helped to trace the evolution processes and acceptable standards of the organizational culture either in tangible or intangible forms among team members. The stringent classifications of cultural traits in any organization are functions of the behavioural depositions of the workforce, clients and stakeholders in line with the ideals and philosophies of the organization. The way things are done here is peculiar to the way things are done there. That is the tenet of organizational culture, not any two are the same though organizations could be similar. However, the fingerprints that specifically identify the uniqueness of any organizational culture are in the application of statistics for the presumable co-mingling and thus bring out the typical biomarkers of the organization. In this study, the statistics of core cultural values of the Petroleum Technology Development Fund (PTDF) were aggregated, synthesized and analysed for organizational integration based on the core value needs of the Fund. Certain identifiable cultural traits were sorted, classified and marked as cultural obligations (terminators) while others were rated as assets for the enhancement of organizational high performances (enablers), meant to be adopted for decision making. Where there are challenges of cultural adaptations, the benefits are unquantifiable in dynamic reforms. This study is therefore useful for policy formulation and decision making in the oil and gas sector and for performance evaluation.

Nigeria is blessed with a considerably large deposit of solid minerals, of which barite is one of it. The industrial need for barite has increased over the period as oil and gas exploration and exploitation grew because barite is used as a weighting agent in drilling fluids. Though, this is not the only application of barite. This resulted in the massive importation of barite for use by oil and gas firms operating in Nigeria. However, we sit on a deposit of barite, and we also import it, losing high foreign exchange earnings owing to some studies that revealed that Nigeria has low grade barite which is not meeting up with the API’s specification. In fact, some deposits of barite have not been explored for first time. This review paper has revealed a good number of studies done by researchers in the recent past, showing the rheological properties of local barite measuring up the imported ones and the API’s specific gravity is 4.2 and some works reviewed showed high grade barite have specific gravity (S.G) of 4.2 and little above. The previous studies showed that drilling mud treated with local barites have the required rheological properties for safe drilling operation. The fluid loss property of local barite is a little lower that the API standard and the imported barites but improved when 10 g Torkula barite was used to enhance the filter cake quality and reduce the fluid loss (Afolayan, et al., 2021). This review will serve as a boost to Government’s and agencies’ efforts to go full ball into extraction and processing barite in Nigeria to bridge the gap in the supply chain of local barite in Nigerian oil and gas industry in order to increase foreign exchange earnings. Keywords: Barite, Drilling fluid, Specific Gravity, Weighting Agent and API Specification.
尼日利亚有幸拥有相当丰富的固体矿物矿藏，重晶石就是其中之一。随着石油和天然气勘探和开发的增长，工业对重晶石的需求也在增加，因为重晶石被用作钻井液中的加重剂。不过，这并不是重晶石的唯一用途。这导致重晶石大量进口，供在尼日利亚经营的石油和天然气公司使用。然而，我们坐着重晶石的存款，我们也进口它，失去了高额的外汇收入，因为一些研究表明，尼日利亚的重晶石品位低，不符合API的规范。事实上，有些重晶石矿床并非首次发现。本文回顾了近年来研究人员所做的大量研究，表明本地重晶石的流变性能与进口重晶石相当，原料药比重为4.2，一些研究表明高品位重晶石的比重(S.G)为4.2或略高于4.2。以往的研究表明，经过局部重晶石处理的钻井液具有安全钻井作业所需的流变性能。本地重晶石的滤失性能略低于API标准和进口重晶石，但加入10 g Torkula重晶石可提高滤饼质量，减少滤失(Afolayan, et al.， 2021)。这项审查将促进政府和机构全力投入尼日利亚重晶石的开采和加工，以弥合尼日利亚石油和天然气行业当地重晶石供应链的差距，从而增加外汇收入。关键词:重晶石，钻井液，比重，加重剂，API规格

Domain specific modelling languages (DSMLs) are special purpose languages that have been designed and tailored for specific application domains. With domain specific features user of the language can construct with very familiar notations and get desired outcomes. The focus in this paper is on the functionality of a domain server in a domain specific modelling language for modelling oil and gas pipeline design. A domain server is coupled to a range of pipeline physical components by a pipeline context model, each of the components having a variety of pipeline built units, attributes and values. The domain server stores data received from at least one of the range of the pipeline physical components, the data including values associated with one or more attributes of the components. The domain server derives a model type for at least one phase from the lifecycle of the pipeline design operation for the first instance of the pipeline built units, based on analytics of information stored in the pipeline built units memory and the component attributes storage, where the model type includes a set of attributes for at least one of the range of pipeline physical components. In addition, the domain server generates an orientation for performance operation of an instance including one or more actions from the pipeline built units corresponding to at least one attribute of the set of attributes Keywords: Attribute sets, model type, built units, pipeline context model (PCM)
