GAS LIFT OPTIMIZATION OF A MATURE WELL IN NIGER DELTA, NIGERIA USING INCOMPLETE DATASET: A CASE STUDY
Authors: E. Eyankware Oghenegare , Ateke Idaereesoari Harriet , Joseph Okonta Nnamdi
Published: November 2020

Well DEF, a well located in Niger Delta region of Nigeria was shut down for 7 years. On gearing towards re-starting production, different options such as installation of gas lift mechanism, servicing and installation of packers and valves were evaluated for possibility of increasing well fluid productivity. Hence, this research was focused on optimizing well fluid productivity using PROSPER through installation of continuous gas lift mechanism on an existing well using incomplete dataset; in addition, the work evaluated effect of gas injection rates, wellhead pressure, water cut and gas gravity on efficiency of the artificial lift mechanism for improved well fluid production. Results of the study showed that optimum gas injection rate of 0.6122 MMscf/day produced well fluid production of 264.28 STB/day which is lower than pristine production rate (266 STB/day) of the well. Also, increment in wellhead pressure resulted in decrease in well production, increase in water cut facilitated reduction in well fluid productivity while gas gravity is inversely proportional to well fluid productivity. Based on results obtained, authors concluded that Well DEF does not require gaslift mechanism hence, valves and parkers need to be re-serviced and re-installed for sustained well fluid.

Published: November 2020

A judicial institution is called good, not only if the process is honest, clean, and impartial. But in addition there are more criteria that must be met, namely principles that are open, corrective, and recordive. In this criterion, one side that deserves the attention of judicial management is the existence of a good legal remedial system as part of the principle of fairness and trial independence which are universally recognized principles. The broadest opportunity to submit corrections and recordings of decisions that have permanent legal force (inkracht) deemed unfair by justice seekers can be done through a Judicial Review. However, the Judicial Review is very limitative, one of them with the requirement for novum. But the regulation of conditions can be said to be a condition as a novum not strictly regulated. Seeing this raises a problem about, "What is the validity of a court decision that has not been inkracht as a novum in submitting a review?". The method used in this study is a normative or juridical legal research method.

Kreativitas adalah salah satu kemampuan inovasi yang dibutuhkan pada abad 21. Hal inilah yang menjadikan kreativitas menjadi syarat untuk tetap dilatih dan dibiasakan pada setiap individu. Kreativitas juga perlu ditekankan pada pembelajaran matematika. Alasan mengapa kreativitas perlu ditekankan adalah siswa dapat menemukan solusi-solusi asli saat memecahkan masalah. Selain itu matematika terlalu kompleks dan luas jika harus diajarkan dengan hafalan..Salah satu cara yang dapat dilakukan adalah membiasakan siswa dengan memberikan soal yang menuntut siswa untuk mengeluarkan seluruh ide kreatif yang dimiliki. Soal open-ended merupakan salah satu tipe soal yang dapat digunakan untuk mengetahui kreativitas siswa. Soal open-ended adalah pertanyaan yang memiliki beberapa cara untuk meyelesaikannya. Akan tetapi pertanyaan terbuka tidak menerima setiap jawaban yang diberikan oleh siswa. Pertanyaan terbuka menuntut siswa untuk mampu bepikir rasional tentang alasan-alasan yang digunakan untuk menjawab pertanyaan. Di samping itu, kinerja seseorang dalam matematika juga dipengaruhi oleh efikasi diri. Efikasi diri adalah keyakinan seseorang tentang kemampuan diri yang mampu mempengaruhi seseorang dalam bertingkah laku dan upaya-upaya yang dilakukan ketika menghadapi suatu masalah. Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk mendeskripsikan kreativitas siswa SMP dalam menyelesaikan soal matematika open-ended ditinjau dari efikasi diri.

Coal Companies’ Trade Credit Policy
Authors: SIERPIŃSKA Maria
Published: November 2020

The paper presents issues related to the use of trade credit by coal companies during the 2014-2016 downturn and the upturn of 2017–2018 in the coal industry. Coal companies are at both ends of trade credit, as providers and recipients. Research shows that they financed their activities by means of trade credit more widely than they granted it to coal buyers throughout the entire period. In the downturn, coal companies were keener to credit coal buyers than during the boom in the industry thereby suffering an increased risk of not recouping their receivables. This was reflected in the level of provisions for doubtful receivables. The decline in credit granted to buyers during the downturn is corroborated by a decline in the receivables cycle.

Published: November 2020

This paper discusses analysis of the innovative activities of mining companies in the years 2016–2018 against the background of innovation active industrial enterprises. In addition, reference is made in the article to the previous findings and research in the field of the level of innovation of mining companies. Despite the fact that the mining industry belongs to traditional industries and is considered to be not very innovative, it undertakes innovation activities necessitated by the need to bring the coal-fired power generation to market competitiveness, ensure industrial safety of miners and environmental protection. In recent years, mainly process innovations have been introduced, which is due to ongoing industry-restructuring processes. Despite the risks, the industry should recognise the opportunities in the current situation and try to use them for further innovations. The main objectives of the energy sector included in the Program for the hard coal mining sector in Poland should be pursued particularly through building new knowledge and innovation intensive competitive advantages. The implementation of clearly defined directions of innovation strategy in accordance with the provisions of the documents governing the Mining of Hard Coal section in Poland will enable its later functioning, country's energy independence and competitiveness of the national economy.

Published: November 2020

The wild boar is one of the most invasive species among large mammals in both its native and introduced ranges. This species represents a main threat for crops and biodiversity and a pest for the pig industry due to the rapid expansion of the African swine fever. Because of its peculiar life history traits, population control programmes and recreational hunting are usually unable to effectively reduce the number of wild boars. Therefore, a reliable approach based on appropriate, cost‐effective, monitoring methodologies is urgently required. Effective monitoring should adopt effective sampling strategies, otherwise the detection of population trends can be erroneous and resulting in a mismatch of appropriate management actions. First, we review the status‐of‐the‐art of wildlife monitoring with a special focus on wild boar and feral pigs. Then, we show that nocturnal distance sampling, carried out using thermal cameras, can be an effective monitoring technique for wild boar population assessment regardless of the characteristics of the sampled area. Using data from multiple surveys performed in four study areas in Italy, characterised by contrasting topography, habitats and level of environmental visibility, we found that the estimate of precision is generally good and almost independent of landscape conditions. A simple method to estimate visibility, which may empirically help wildlife managers to design effective nocturnal distance sampling surveys, is proposed. The bias of our population estimates is evaluated using simulations showing that in some areas the estimate is unbiased, while in others there is the tendency towards a negative bias. Based on reported results, we provide guidelines to perform nocturnal distance sampling of wild boar populations.
Nothing else matters? Food as a driving factor of habitat use by red and roe deer in winter?
Authors: Bobrowski Maria , Gillich Benjamin , Stolter Caroline
Published: November 2020

Habitat use by cervids can have large effects on vegetation. Therefore, factors influencing habitat use are pertinent to ecology, nature conservation as well as management of forests and hunting. The aim of this study was to identify factors influencing habitat use by red and roe deer, Cervus elaphus and Capreolus capreolus, in the Lüneburger Heide, Germany. We used faecal pellet counts as an indicator of habitat use and applied generalized linear models to conclude that habitat use by both cervids was largely explained by the availability of food plants. In particular, the occurrence of bilberry Vaccinium myrtillus and deciduous trees such as beeches Fagus sylvatica were of major importance. Nonetheless, red and roe deer showed preferences for different plant species, but for both deer, the presence of large trees and conifers, with exception of young Norway spruce Picea abies providing shelter for roe deer, was less attractive. Furthermore, the proximity of mineral licks was important for both cervids. Relative to roe deer, red deer showed a stronger avoidance of well‐used paths. Surprisingly, landscape features such as distance to settlements and elevated hunting standshad no significant effect. Our study demonstrates similarities and differences in habitat use of two important herbivores of the Northern temperate forests. We propose that managers establish ‘decoy’ sites for deer: areas with a high proportion of ground vegetation and young trees of lower forestry value. This will serve to divert deer from valuable trees and thereby enhance biodiversity. These open stands could be interspersed with dense islands of young coniferous trees to offer shelter and should be distant to frequently used pathways. Mineral licks may help enhance use of these sites. Providing an attractive resource for both species of cervids is the best way to manage large herbivores in economically valuable forests.

Pada tanggal 31 Desember 2019, Tiongkok melaporkan kasus pneumonia misterius yang tidak diketahui penyebabnya. Dalam 3 hari, pasien dengan kasus tersebut berjumlah 44 pasien dan terus bertambah hingga saat ini berjumlah ribuan kasus. Pada awalnya data epidemiologi menunjukkan 66% pasien berkaitan atau terpajan dengan satu pasar seafood atau live market di Wuhan, Provinsi Hubei Tiongkok. Sampel isolat dari pasien diteliti dengan hasil menunjukkan adanya infeksi coronavirus, jenis betacoronavirus tipe baru, diberi nama 2019 novel Coronavirus (2019-nCoV).  Pada tanggal 11 Februari 2020, World Health Organization memberi nama virus baru tersebut Severa acute respiratory syndrome coronavirus-2 (SARS-CoV-2) dan nama penyakitnya sebagai Coronavirus disease 2019 (COVID-19). Penelitian ini menggunakan metode review article. Sumber data penelitian ini berasal dari literatur yang diperoleh melalui internet berupa hasil penelitian dari publikasi jurnal Internasional. Namun, belum ada obat terapeutik khusus untuk penyakit menular ini. Sejauh ini terapi yang cukup efektif sebagai terapi penanganan covid 19 adalah terapi menggunakan Favipiravir. Faviparavir merupakan obat baru golongan inhibitor RNA-dependent RNA polymerase (RdRp) yang dapat menghambat aktivitas polimerasi RNA. Meskipun demikian COVID-19 adalah penyakit baru yang telah menjadi pandemi. Penyakit ini harus diwaspadai karena penularan yang relatif cepat, memiliki tingkat mortalitas yang tidak dapat diabaikan, dan belum adanya terapi definitif. Masih banyak knowledge gap dalam bidang ini sehingga diperlukan studi-studi lebih lanjut.
