Mangroves of the Niger Delta are the largest in Africa and are the source of numerous ecosystem services such as firewood, seafood, building materials and medicinal herbs. Their sustainable use and protection are important for future generations. However, anthropogenic activities such as oil and gas exploration, urbanization, industrialization, dredging, overexploitation and sand mining are the major disturbances that have pushed the mangroves to the brink of extinction. Therefore, in other to restore lost areas of the mangroves natural and artificial means can be adopted to bring them to a restored state. More often than not emphasis of recovery had been placed on artificial remediation and restoration, where polluted sites are cleaned with chemicals and nursery seedlings transplanted to remediated such sites. Nevertheless, this chapter discusses the possibility of utilizing natural means of forest recovery through seedling recruitment and regeneration. This can be achieved by establishing the right environmental conditions such as setting up of a hydro-channel to ensure smooth inflow and out flow of river water carrying seeds, availability of parent mangrove trees to supply the seeds, and the availability of the right soil condition to enable seedling germination and growth. The use of dried and ground mangrove parts as a new way for restoring polluted soil is discussed; in addition, the unconventional proposition of using low key pollution to manage and increase forest resilience is highlighted in this work even though further studies are recommended. Future direction of mangrove restoration should be tilted towards the application of the force of nature, which has the potentials of reversing the adverse effect of anthropogenic activities in well managed and protected sites.

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.

Due to rapid urbanization, increase in coastal population, oil and gas exploration and other array of anthropogenic activities within the Niger Delta region of which Rivers and Bayelsa states are prominent amongst others, the region has been faced with coastal water pollution. There is need therefore, to evaluate the intensity of environmental contamination of the aquatic ecosystem in this region, thus this study was conducted to investigate the heavy metal levels of Clams (Egeria radiata) sold in open markets in Port Harcourt (Rivers State) and Yenagoa (Bayelsa State). Samples were collected from three markets in Port Harcourt (Mile 1, Rumuokoro and Mile 3), and three markets as well in Yenagoa (Opolo, Swali and Tombia) respectively. The samples were collected bi-weekly for 3 months and transported to the laboratory for analysis of heavy metals (Cr, Cd and Pb) levels using standard scientific method of analysis. The analysis was done in triplicates for each sample and data obtained were subjected to statistical analysis using excel spreadsheet and statistical package for social sciences (SPSS) version 21. The results revealed that samples collected from markets in Port Harcourt had higher concentrations of heavy metal than that of Yenagoa, though, the heavy metal levels were below World Health Organisation permissible limits, except for Cadmium (Cd) that ranged from 0.54±0.002 to 0.78±0.00 mg/kg in samples collected from Port Harcourt, against 0.5 mg/kg recommended by WHO. This could be attributed to oil and gas exploration, and discharges of industrial and domestic wastes bearing cadmium, and poses serious health risks. Therefore, routine monitoring and assessment of the aquatic ecosystem will be vital to forestall further contamination.

Hierarchy Process

Pelaksanaan kegiatan operasional di area offshore pada perusahaan eksplorasi dan eksploitasi minyak dan gas bumi membutuhkan bahan bakar yang cukup banyak. Bahan bakar ini sebagian besar digunakan untuk mobilisasi berbagai jenis kapal sebagai fuel object dan operasional harian proses produksi. Terdapat beberapa kriteria umum yang menjadi dasar penjadwalan pengisian BBM, namun setiap koordinator berhak menyusun penjadwalan berdasarkan pengalaman dan subjektifitas masing-masing. Oleh karena itu jadwal yang disusun antar koordinator bisa sangat berbeda, agar memiliki standar yang seragam maka sangat diperlukan suatu metode yang terstruktur dengan kriteria standar dalam pengambilan keputusan penyusunan penjadwalan pengisian BBM. Penelitian ini bertujuan untuk mengetahui kriteria apa saja yang menjadi dasar pertimbangan dalam penjadwalan pengisian BBM dan mengembangkan suatu sistem agar keputusan penjadwalan yang diambil bisa terukur dan dipertanggungjawabkan dengan baik. Metode yang digunakan pada penelitian ini adalah rating approach Analytical Hierarchy Process (AHP), sedangkan pengelompokan kapal (klaster) yang akan diisi menggunakan metode hierarki agglomerative, complete linkage dengan euclidean distance. Hasil dari penelitian ini menunjukkan bahwa area kerja akan dibagi menjadi 3 klaster dengan jumlah SPOB sebanyak 3.  Selanjutnya kriteria yang dijadikan dasar pertimbangan dalam pengambilan keputusan penjadwalan pengisian BBM adalah  fuel remaining day fuel object, prioritas operasi, akses menuju fuel object dan jarak SPOB dengan fuel object. Berdasarkan analisis implementasinya, metode penjadwalan dengan menggunakan rating approach AHP dapat memberikan jadwal yang konsisten, terukur,bisa dipertanggungjawabkan, dan sangat mudah diimplementasikan serta dapat menghindari terjadinya perbedaan penjadwalan (subjektivitas) antar koordinator.        Abstract[Fuel Distribution Scheduling For Self Propelled Oil Barge (SPOB) Based On The Hierarchy Process Analityc Method] The implementation of operational activities in the offshore area of oil and gas exploration and exploitation companies requires quite a lot of fuel. This fuel is mostly used for the mobilization of various types of ships as a fuel object and for the daily operations of the production process. There are several general criteria that form the basis for scheduling refueling, but each coordinator has the right to arrange a schedule based on their own experience and subjectivity. Therefore, the schedule prepared between the coordinators can be very different, in order to have a uniform standard, it is necessary to have a structured method with standard criteria in making decisions on the preparation of fuel filling scheduling. This study aims to find out what criteria are the basic considerations in scheduling refueling and develop a system so that scheduling decisions taken can be measured and accounted for properly. The method used in this study is the rating approach Analytical Hierarchy Process (AHP), while the grouping of ships (clusters) to be filled using the agglomerative hierarchy method, complete linkage with euclidean distance. The results of this study indicate that the work area will be divided into 3 clusters with the number of SPOB as much as 3. Furthermore, the criteria that are used as the basis for consideration in making decisions about fuel filling scheduling are fuel remaining day fuel object, operating priority, access to fuel object and distance between SPOB and fuel. objects. Based on the implementation analysis, the scheduling method using the AHP rating approach can provide a schedule that is consistent, measurable, accountable, and very easy to implement and can avoid scheduling differences (subjectivity) between coordinators.Keywords: Analytical Hierarchy Process; Fuel Object; Scheduling; SPOB

This paper is principally concerned with native title issues as they affect oil and gas exploration and production. However, it also reviews Aboriginal heritage laws and practices because they have the potential to be just as disruptive to an expeditious exploration program or to the construction of a production facility as do native title claims.The paper focusses on onshore petroleum exploration and production because the right to negotiate under the Native Title Act (NTA) does not apply offshore. However, the paper does consider offshore because the NTA can still affect offshore petroleum explorers and producers; either because their area of interest could include an island within a State or Territory jurisdiction or because the facilities to treat the offshore oil and gas could be located onshore.The paper examines the key provisions of the NTA which are relevant to petroleum explorers and producers, principally the subject of tenure to ground. It considers the validity of already granted titles. It then examines the process of application for new titles.Although the NTA is the common source of problems throughout Australia, it is necessary for the paper to consider the situation in each State and Territory, since the titles are different and the government processes of dealing with native title issues differs in each jurisdiction.Although the focus of the paper is on how to cope with the right to negotiate, the paper considers some of the categories of future acts in respect of which the right to negotiate does not apply (specifically, procedures for infrastructure titles, renewals and extensions of titles, the expedited procedure, indigenous land use agreements, reserve land and approved exploration etc acts).The paper mentions the Federal Court decisions in the Miriuwung Gajerrong and Croker Island native title claims and ponders the options for the High Court in deciding the recent appeals.The paper’s conclusion is that a negotiated agreement is the only way to cope with native title issues. The contents of such an agreement are considered.

Exploration Activity

Exploration activity in Australia in 2013 occurred across a broad spectrum of conventional and unconventional plays. Competition for acreage was buoyant with large tracts of key onshore basins either licensed or under application. Offshore, there were new awards on the western Australian margin and in the Bight Basin off SA. Offshore 3D seismic acquisition was reduced from anomalously high levels in 2012. Onshore 2D seismic acquisition was at historic highs and onshore 3D was the most ever recorded. Overall drilling levels were maintained despite a decline offshore. Of 13 offshore wells drilled, six were discoveries. Sixty-nine exploration wells (excluding CSG wells) were drilled onshore. Fifty addressed conventional, and 19 were unconventional shale or basin-centered gas targets. Sixty of the 69 wells were drilled in the Cooper/Eromanga Basin where conventional oil and gas exploration yielded 11 oil and six gas discoveries. Drilling and fraccing campaigns in the Nappamerri Trough unconventional gas plays provided early encouraging results. 213 exploration and appraisal CSG wells were drilled in the CSG basins of Queensland and NSW. In Queensland a record total of 1,317 CSG wells were drilled in fiscal year 2012/2013. Shale gas exploration activity was increasingly focused on the Palaeozoic and Proterozoic Basins of Western, Central and Northern Australia with major oil and gas companies involved in joint ventures preparing for drilling in 2014. The results of these programmes will have an important bearing on the future direction of exploration in these plays.

The Niger Delta in Nigeria is the largest wetland in Africa and the third largest mangrove forest in the world. The region is known for its richness in biodiversity as well as its oil and gas resources. Due to the high level of oil exploration, deforestation, hunting and insecurities in these areas, the wildlife especially endemic species like the Niger Delta red colobus becomes vulnerable to extinction. Most researches on their range have noted a significant reduction in their population and range distribution. Hence, up-to-date information on their current status is paramount to ensure proper and urgent conservation measures. Data was obtained through the use of field survey and secondary data. The species was recently discovered endemic to Niger delta region in Nigeria for about 23 years ago and recent studies observed that there has been a drastic reduction in their population and a shift in the range they formally occupied faulting this to anthropogenic activities. This study revealed that the location is under intense timber extraction and hunting and as a result, one of the location in the Apoi creek where it was reported to be present, record no species of Red colobus monkey. Only the red capped mangabey monkey (3) were sighted at the location with some evidence of alligator (10). Result also revealed that most of the communities (age ≤ 30) do not know or have seen the species. The situation at the location is exacerbated because of the level of poverty and insecurity in the areas. Going by the evidence of intense timber extraction and hunting at the location, the number of this species may have drastically reduced compared to what it was formally projected (±200 individuals). It is therefore strongly recommended that a follow up of the research is done in other location where it was reported to be present.

Pollution associated with oil and gas exploration causes huge environmental damage. It is mainly caused by oil spills, gas flaring, effluent discharge and human error and these impacts on health, environment, and culture, economic and social activities of people. Recently, spills appear to be the main cause of oil-related pollution because many countries have worked hard to reduce flaring which is also a major source of pollution in the industry. In Nigeria, pollution from exploration activities is mainly caused by oil spills and gas flaring[1]which had led to many problems including health complications such as serious respiratory problems cancer, kidney and liver problems or even deaths, destruction of farmlands, fishing industry, tourism facilities and cultural areas. It has also led to community conflicts, violence and frustration, militancy, reduction in tourism and hospitality industries, and loss of biodiversity and destruction of habitats. This paper holistically looked at these impacts and examined them in the context of the Niger Delta situation. It generally raises and seeks to provide answers to some important questions: why are these problems grave in Nigeria and the role the negative impacts had played in anti-social behaviour, crises and criminality in the Niger Delta? In answering the questions, the paper examines actions taken by stakeholders to ameliorate the impacts while making few references to other jurisdictions where appropriate. It concluded that the impacts of spills and oil-related pollution are one of the main reasons why militancy and other societal ills have taken the centre stage in the Niger Delta. It recommends a more tailored solution in dealing with oil pollution and problems caused by it.

This study will identify the extent in which American oil companies make billions daily from oil production, while local Nigerians suffer daily from poverty. The focus of this research will be on the population of Niger Delta, Shell Oil Company and the Nigerian government. I will define and establish an illustration of the poverty-structured environment that surrounds Niger Delta and the revenue success of Shell Oil Company and Nigerias government. This research will open the eyes of American oil companies, Nigerias federal government and people around the world to the revenue that is coming into Nigeria, but the communities are still living in poverty. Something needs to be done; if something is not done, some the people of Niger Delta will continue to retaliate.
