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.

AbstractCrude oil and produced water samples obtained from ten wells in an offshore field, Niger Delta, were analyzed, in order to determine the occurrence of naphthenates deposition in the field. Total acid number (TAN) and °API of the crude oil samples, pH and metal ions concentrations of the produced water samples were determined. The results revealed that TAN values ranged from 0.47 to 1.01 mgKOH/g with pH of 6.9–8.9, which were above established threshold. The metal ions concentrations especially for Ca++ and Na+ were relatively high. These imply a high possibility of metal-naphthenate precipitation in the oil production facilities in this field.

Legends, myths and plain old misinformation abound of whale migrations interrupted by international shipping, dolphin populations displaced by dredging activities, and of seismic survey campaigns resulting in disoriented, beached whales. While risks exist, in truth the Australian petroleum industry continues to demonstrate that it can successfully coexist productively alongside populations of cetacean. These whales and dolphins are seemingly able to at least tolerate, if not actually be undisturbed by, underwater noise. Other risks to cetaceans from oil and gas activities, whether actual or perceived, encompass vessel strike, turbidity plumes from dredging, port developments, underwater blasting, spills, the laying and operation of pipelines, and similar. URS Australia’s John Polglaze is a specialist in the environmental impact evaluation of underwater noise, and has over 15 years experience in marine environmental management and impact assessment following nearly 20 years service in the Royal Australian Navy. John presents on the range of environmental impact assessment challenges for the oil and gas industry in Australian coastal and offshore regions, and effective, pragmatic solutions for demonstrating low risks to cetaceans and other sensitive marine fauna. These include the application and limitations of computer-based models to predict underwater noise and blast propagation, the development of a risk assessment framework that has proven effective with state and Commonwealth regulators, and case studies of real-life interactions between the petroleum industry and cetacean populations. In particular, he will discuss how misunderstanding and misapprehension of these complex issues unnecessarily complicates the challenges of environmental compliance. This topic is timely, given that Australia’s rapidly increasing whale populations, coupled with the continued expansion of offshore petroleum activities, will lead to more frequent interaction between and overlap of cetaceans and oil and gas activities.

Australia could have shale gas resources several times bigger than the existing conventional gas resource base, which is estimated at about 5,300 BCM (190 TCF) by Geoscience Australia (GA). The Australian Government has no estimate of potential shale gas resources. The US Department of Energy (EIA) in 2011 estimated Australian shale gas resources to be 400 TCF. The quantity of this estimate is supported by an Australian study—which estimates resources of 600 TCF—conducted by Advanced Well Technologies (AWT) in conjunction with DSWPET. While there are significant technical differences between the shale gas plays in the US and Australia, it is too early to tell if the technical differences are barriers. There are also significant differences in the commercial landscape. The lack of capacity in Australia has lead to much higher costs for drilling and fracture stimulation than in the US. The size of the domestic gas market is much greater in the US and its existing infrastructure allows for production to come onstream quickly. In Australia this infrastructure is not present in most areas and the domestic market cannot support another large gas development. Perhaps the greatest challenge to this great opportunity is politics. There is a public, hence political,perception that all gas sources have the same gasland problems. These perceptions can be changed. First, the petroleum industry and governments need to understand the potential size of the gas resource and the possible strategic opportunity for Australia. Also these parties need to recognise that the shale gas resources are often located away from areas of high social and environmental impact. Once these factors are understood by these parties, factual information about the environmental impact of shale gas plays in comparison with coal seam methane and other alternative gas supplies can be factored into gas resource planning.

Abstract Produced water (PW) from petroleum reservoirs often contains heavy metals and other contaminants that are harmful to the environment. Most of the commonly used treatment techniques have been reported to be ineffective in reducing some of the contaminants’ concentrations to recommended disposal levels. This study evaluated the effectiveness of four selected bio-adsorbents combined for treating PW from Niger Delta oil fields. In this study, orange peels (I), banana peels (II), sponge gourd (Luffa cylindrica) (III) and palm kernel fibers (IV) were washed with distilled water, sun-dried (24 h) and dried in the oven at 105 ± 5 °C (3 h, I and II), 150 °C (30 min, III) and 80 °C (3 h, IV). They were ground into powder, sieved (150 μ, Group A) and (300 μ, Group B), washed with 0.4 mol/L HNO3, filtered and rinsed with distilled water. Samples of PW were obtained from fields R, X, and Y in the Niger Delta and analysed for heavy metals using an atomic absorption spectrophotometer (AAS). Samples were treated in adsorption column over 6 h using the adsorbents simultaneously. Treated samples were analysed with AAS and characterised. Adsorption of heavy metals were assessed using Langmuir and Freundlich models. Data were analysed using regression and other statistical methods. For the 150 μ size of sample R, the percentage reductions for the metal concentrations (Pb, Ni, Cd, Cu, Fe, Mg, Cr, Zn, Mn, Ca, Ar, B, Sn and Ba) were found to be 100%, 52.7%, 100%, 100%, 85.87%, 19.48%, 100%, 92.8%, 17.74%, 98.86%, 22.32%, 29.56%, 78.06% and 44.74%, respectively, while the reduction in 300 μ size were 1.52%, 97.2%, 71.4%, 17.1%, 43.8%, 45.6%, 7.04%, 89.6%, 35.4%, 99.6%, 0.0001%, 1.19%, 14.19% and 0.002%, respectively. The finer adsorbents were more effective. Similar results were obtained for PW samples from the other fields. Produced water from Niger Delta oil fields was effectively treated of contaminants using four selected bio-adsorbents mixed simultaneously.
