The Impact

This writing will focus on the impact on the impact of oil and gas development on the landscape, surface water and groundwater of the Niger Delta – while also assessing the various means of remediation in use. Geologically, the Niger Delta petroleum systems consist of Lower Cretaceous , Upper Cretaceous–lower Paleocene and Tertiary. When Nigeria became an independent nation on 1 October 1960, Shell–BP began to relinquish its acreage and its exploration licenses were converted into prospecting licenses that allowed development and production. The Federal Government of Nigeria started its Department of Petroleum Resources Inspectorate in 1970 and Nigeria joined the Organization of the Petroleum Exporting Countries in 1971. – and in order to take control of the country’s petroleum industry, Nigeria nationalized BP’s holding completely in 1979, and Shell–BP became Shell Petroleum Development Company of Nigeria. Oil spillages routinely occur in the Niger Delta. The official figures of SPDC show that between 1976 and 2001, 6,187 incidents in which 3 million barrels were spilled. The Niger Delta Environmental Survey An impact assessment of the 1983 Oshika oil spill. Spills of crude oil in Niger Delta farmlands have been reported since 1971. In general, toxicity depends on nature and type of crude oil , level of oil contamination, type of environment and degree of selective of individual organisms. Controlled burning effectively reduce the amount of oil in water, if done properly but it must be done in low wind and can cause air pollution. A principal target for emissions reduction is flaring and venting which causes most of the air pollution. Saltwater tanks can be often susceptible to lightning strikes due to build up in static electricity, with the spilled oil spreading to surrounding lands, waterways. This requires a secondary containment of the tanks that makes it easier to clean up the inevitable spill. In cases of expected major storms or flooding events, crude oil can be removed from tank batteries while refilling the tanks with saltwater to prevent them tipping over during the flooding event.

The Impact

In Nigeria, the self-proclaimed ‘Giant of Africa’, the same scenario has been playing for the past fifty years to devastating effects especially in the Niger Delta, where oil is extracted in Nigeria. The entry of oil companies into the Niger Delta has no doubt brought great financial wealth. Despite these concerns, multinational oil companies operating in the Niger Delta region have failed to adopt best practice strategies for risks mitigation and comply with environmental regulations. This essay will focus on the impact on the impact of oil and gas development on the landscape, surface water and groundwater of the Niger Delta – while also assessing the various means of remediation in use.A total of about 1,182 exploration wells have been drilled to date in the delta basin, and about 400 oil and gas fields of varying sizes have been documented. Geologically, the Niger Delta petroleum systems consist of Lower Cretaceous, Upper Cretaceous–lower Paleocene and Tertiary. According to , a large portion of the world’s oil and gas reserves are in tertiary terrigenous passive continental margins – accounting for the significant hydrocarbon deposits Nigeria’s Niger Delta. The ecological zones can be broadly grouped into tropical rainforest in the northern part of the Delta and mangrove forest in the warm coastlines of the south.

The instability of crude oil prices at the international market which results in revenue drop to oil and gas operators, the high cost of drilling multiple injection wells and installing gas reinjection systems in a bid to improve recovery of crude oil, have been of great concern to the Petroleum Industry. The Economic viability of Gas Reinjection for Enhanced Oil Recovery (EOR) (as against the gas flaring operation) was analyzed with 7 wells located onshore, in the Niger Delta region of Nigeria. The production history and reservoir data were gathered with which the cost analyses were conducted. Two scenarios involving seven production wells were evaluated. The first was converting two of the production wells to gas injection wells and producing from the remaining 5 production wells (IN2PROD5) and the other was injecting gas in two newly drilled injection wells and producing from the seven production wells (INJ2PROD7). It was shown that (INJ2PROD5) is a preferred option in extending the productive life of an otherwise depleted and uneconomic oilfield, having higher Net Present Value (NPV), Profitability Index (PI) and Internal Rate of Return (IRR) of -$53MM, 0.93 and 27.40% while the INJ2PROD7 had $161MM, 1.39 and 37.75% at discounted rate of 30% respectively. After subjecting the expected net revenues under various crude oil price sensitivity market vagaries, INJ2PROD5 will stand the test of time as it is less expensive and yielded a higher gross profit which is the major factor in any investment decision making.

Geopolitical Risks

The article is devoted to the consideration of geopolitical challenges for the analysis of geoenvironmental risks (GERs) in the hydrocarbon development of the Arctic territory. Geopolitical risks (GPRs), like GERs, can be transformed into opposite external environment factors of oil and gas industry facilities in the form of additional opportunities or threats, which the authors identify in detail for each type of risk. This is necessary for further development of methodological base of expert methods for GER management in the context of the implementational proposed two-stage model of the GER analysis taking to account GPR for the improvement of effectiveness making decisions to ensure optimal operation of the facility oil and gas industry and minimize the impact on the environment in the geopolitical conditions of the Arctic.The authors declare no conflict of interest

Hydrocarbon resources have become the most essential commodity contributing to any nation’s growth and development in the recent years. For the past decades now, the quest for hydrocarbon resources has been increasing in an arithmetic rate that its supply can no longer meets the demand for its consumption today. In petroleum industry, seismic and well log analyses play a vital role in oil and gas exploration and formation evaluation. This study is aimed to effectively characterize the reservoirs and analyze the by-passed pay in Philus Field, Niger-Delta, Nigeria in order to look into the economic viability and profitability of the volume of oil in the identified reservoir(s). The faults in the study area trend in NW-SE direction and dip towards the south. Seven reservoirs were mapped on Philus field. A discovery trap and a by-passed (new prospect) trap were mapped out on the field. The petrophysical analysis showed that porosity of Philus field was 0.24. The volumetric analysis showed that the Stock Tank Original Oil in Place of discovery trap (Philus field) ranged from 1.6 to 43.1 Mbbl while that of new prospect trap ranged from 18.1 to 211.3 Mbbl. It is recommended that the oil reserve of Philus field needs to be recalculated.

The Impact

Field assessments using biochemical and chemical markers in marine organisms will be necessary to provide the Australian Petroleum Industry with a realistic evaluation of the impact of their activities on the marine environment. In field investigations, wild or caged animals are sacrificed and their organs are collected in order to assess if industrial activities do have a significant adverse impact on the organisms' health. Biochemical markers of chronic exposure to contamination may include reversible effects such as induction of a detoxification system, or permanent effects such as damage to nuclear DN A. Studies of sentinel species using biochemical markers of exposure, complemented by chemical analyses provide a realistic holistic method for assessment of environmental health. This multidisciplinary approach has proven valuable in Europe and North America.This paper outlines the need for biochemical and chemical markers to assess environmental health in a dynamic milieu such as the North West Shelf of Australia. Selected biochemical markers for use by the oil and gas industry in field monitoring of ecological health, and the complementary chemical measurements focussed on persistent contaminants such as poly eye lie aromatic hydrocarbons (PAHs), are described. The biological and ecotoxicological significance of the biochemical markers applied in sentinel marine organisms is reviewed, and some limitations regarding their interpretation are stated. It is suggested that biochemical monitoring of the environment complemented with sophisticated chemical measurements can provide environmental managers working within the oil and gas industry with a system for ecotoxicological monitoring programs in offshore Australia.

Abstract Adult birds may use the production of offspring as a measure of habitat quality when prospecting for territories, increasing competition for productive territories. We evaluated the impact of breeding success on territory retention of Pacific (Gavia pacifica) and Yellow-billed (G. adamsii) loons in the National Petroleum Reserve-Alaska on the Arctic Coastal Plain of northern Alaska using mark–resight data and multi-state modeling. We also used behavioral observations of brood-rearing adult loons to quantify the frequency of visits by prospecting loons. We hypothesized that increased competition for productive territories would result in a decrease in territory retention rates. Territory retention rates the year following successful breeding attempts were only slightly lower (0.90) than after failed breeding attempts (0.93), and few territories were consistently successful across years. Overall territory retention rates were high (0.92) and similar for both species, suggesting that adults were able to defend their territories successfully. Males had higher territory retention rates than females, but we found no influence of mass (a possible proxy for fighting ability) on territory retention. These observations, coupled with the high frequency of visits by prospecting loons, provide additional evidence that site familiarity may provide advantages to territory holders. Quantifying territory retention behaviors may also inform land management decisions for oil and gas development in areas where loons are present. High territory retention rates, frequency of visits by prospectors, and limited habitat where new territories can be established suggest that breeding habitat in northern Alaska is saturated and may be limiting Yellow-billed Loon populations. In contrast, Pacific Loons attempting to acquire a territory may be able to form new territories on smaller, unoccupied lakes.

Oilfield Chemicals

The petroleum industry includes the global processes of exploration, extraction, refining, transportation and marketing of natural gas, crude oil and refined petroleum products. The oil industry demands more sophisticated methods for the exploitation of petroleum. As a result, the use of oil field chemicals is becoming increasingly important and has received much attention in recent years due to the vast role they play in the recovery of hydrocarbons which has enormous  commercial benefits. The three main sectors of the petroleum industry are Upstream, Midstream and Downstream. The Upstream deals with exploration and the subsequent production (drilling of exploration wells to recover oil and gas). In the Midstream sector, petroleum produced is transported through pipelines as natural gas, crude oil, and natural gas liquids. Downstream sector is basically involved in the processing of the raw materials obtained from the Upstream sector. The operations comprises of refining of crude oil, processing and purifying of natural gas. Oil field chemicals offers exceptional applications in these sectors with wide range of applications in operations such as improved oil recovery, drilling optimization, corrosion protection, mud loss prevention, drilling fluid stabilization in high pressure and high temperature environment, and many others. Application of a wide range of oilfield chemicals is therefore essential to rectify issues and concerns which may arise from oil and gas operational activities. This review intends to highlight some of the oil field chemicals and  their positive applications in the oil and gas Industries.

Bone deformities are one of the main effects of crude oil exposure in marine fish larvae. Craniofacial and jaw deformities, if severe enough, may restrict feeding and ultimately kill the developing larvae. This study aimed to examine the impact of dispersed crude oil on bone development in Atlantic haddock (Melanogrammus aeglefinus) larvae, a fish species spawning in areas approached for oil and gas exploration in the North Atlantic Ocean. Atlantic haddock larvae were exposed to low (60 μg oil/L), high (600 μg oil/L), or pulsed (0–600, average 60 μg oil/L over time) dispersed crude oil from 0 to 18 days post hatch (dph). Endpoints included survival and growth, bone integrity, and transcriptional parameters, which were assessed during (0–18 dph) and after exposure until the fish reached 8 months of age (243 dph). The results showed that the larvae in the high treatment group had reduction in growth at 2–19, 44, 134, and 243 dph. Craniofacial abnormalities were most severe at 8 and 19 dph. These deformities were not present at 44 dph, possibly because the larvae with deformed jaws failed to feed properly and died. Higher prevalence of spinal deformities was observed in haddocks that survived for 243 dph. Three genes encoding proteins critical for osteoblast function, sp7, postn, and col10a1, were downregulated in the high treatment group larvae. We discuss possible mechanisms of action in the developing larvae after oil exposure. In conclusion, this study shows that larval exposure to oil can potentially have long-term effects on growth and bone integrity in Atlantic haddock.

Theia Energy Pty Ltd1 (Theia Energy) discovered a potential unconventional hydrocarbon resource in the Ordovician Lower Goldwyer (GIII) Formation shale located on the Broome Platform of the onshore Canning Basin. The collation, processing, analysis and interpretation of all available regional data culminated in a successful exploration well, Theia-1 (drilled in 2015), which, based upon petrophysical and core analyses, intersected a 70 m gross oil column at 1500–1570 m depth. Theia-1 recovered essential core and wireline log data required to analyse and assess the play elements and reservoir properties necessary for a viable shale oil and gas development. Utilisation of an ‘Unconventional Play Element’ methodology has proven the unconventional hydrocarbon potential of the GIII Formation, and preliminary modelling indicates that economic stimulated flow rates may be achieved. Further operations (a test well with multi-stage hydraulic fracture stimulation) are scheduled in the coming permit year to further quantify the presence of extractable organic matter in the GIII Formation, assess hydrocarbon flow rates, determine fluid composition and appraise commercial viability. This paper will discuss Theia Energy’s exploration campaign in the onshore Canning Basin starting with the regional evaluation, which encompassed all available geoscience data (offset wells, pre-existing seismic and potential analogue fields) and modern specialised shale analysis (sequence stratigraphy, paleogeography, geochemistry, unconventional petrophysics and petroleum systems modelling), to develop a robust regional geological model for the GIII Formation. Pre-drill analysis reduced exploration risk and successfully identified the key geological play elements essential for the successful Theia-1 exploration evaluation program.
