Open Ethnographic Archiving as Feminist, Decolonizing Practice
Authors: Okune Angela
Published: December 2020

Dubbed Silicon Savannah, Nairobi has become a hot spot of tech development that promises to “save Africa.” Qualitative research—carried out by a tangle of private, academic, and non-profit organizations—is part of the work, promising to reveal how people in Kenya are building and benefiting from a dazzling array of digital products. Amidst the enthusiasm, longstanding problems with ways in which research data in Nairobi is conceived, collected, and shared are easily glossed over. This article advances thinking about the politics of qualitative data, unraveling normative concepts like ethics and transparency by both examining existing data practices and modeling alternatives. I describe the sociotechnical infrastructure underlying the ethnographic project, detailing tactics for deploying an instance of open source software—the Platform for Experimental, Collaborative Ethnography (PECE)—to draw research interlocutors into collaborative effort to understand and build decolonized qualitative data infrastructures. Through such processes I learned that collaborating on data not only refreshes the social contract of qualitative work; it can also enhance its robustness and validity. I advise scholars to better document our own knowing practices in order to attend to the inevitability of margins created through all data practices, including our own

Chinese Computing and Computing China as Global Knowledge Production [Special Section]
Authors: Wu Angela Xiao
Published: December 2020

As data-driven technologies and business models pervade on a global scale, China’s enormous digital economy often signals its dominating power by dint of data extraction. Complicating this view, this critical commentary focuses on knowledge production, an important dimension for examining the ways in which postsocialist China transpires in global political economy in the age of Big Data analytics. First, I show how Chinese commercial surveillance analytics profits from legitimation lent by the West-centric hierarchical academe. Then, I move to transnational academic repurposing of Big Data from China, which becomes increasingly common. Such social research tends to yield specters of China that are untethered to the lived realities of those whose data are taken. Drawing on decolonial thinking and feminist care ethics, this commentary concludes by urging social scientists to “stay with the trouble,” making China “legible” in their computing of Chinese Big Data.
Moral Circuits [Special Section]
Authors: R. Murillo Luis Felipe
Published: December 2020

In this essay, I offer an ethnographic-oriented cartoon as a reflection on a personal experience in moral circuits. First prepared for the 4S meeting in Boston (2017)—under the title “Pedal Transcriba, an Ethnographic Device of (and for) Qualitative Research”—it condenses one dimension of the work of multi-sited research across community spaces for alternative computing in the Pacific. My motivation was to derive the human circuitry from a simple technical object and research moral economies of “open” digital fabrication through the very practice of design and fabrication.
Resisting and Remaking Sex in the Petri Dish, the Clinic, and on the Track
Authors: Pape Madeleine , Latham J.R. , Karkazis Katrina , Ritz Stacey
Published: December 2020

Assemblages of sex are continuously being enacted by policymakers, scientists, and medical providers across a range of settings, resulting in multiple and often contradictory notions of what “sex” is and how it is expressed in the body. As feminist scholars have shown, such enactments are mutable yet resilient, often with the net effect of restricting how “sex” can emerge as a material dimension of our embodied, lived experiences. What happens when feminist scholars seek to intervene in order to promote more complex, entangled, dynamic, and just enactments of “sex” in policy and practice? This lab meeting gathers interdisciplinary scholars to reflect on their experiences of pursuing change in the laboratory, the gender clinic, and on the athletics track.
Impact of Typeface and Colour Combinations on LCD Display Legibility
Authors: Franken Gregor , Pangerc Maruša , Možina Klementina
Published: December 2020

The evolution of high resolution displays, especially liquid crystal displays (LCD), which are among the most commonly used ones, has contributed to a larger number of display readers. Regardless of high resolutions, problems in the legibility of typefaces still occur. Many typefaces may well be readable in print, but cause more difficulties when being read on displays. The aim of this study was to examine the influence of colour contrast on the legibility on LCDs to establish which type style is appropriate for a coloured text to be legible. Two different typefaces specially designed for display use were tested in a satisfactory light-dark contrast of five different colour combinations. The reading speed and fixations were analysed with an eye-tracking device Tobii 120X. Different texts were displayed on an LCD display. The results showed that the selection of a particular colour combination and contrast greatly affects the reading speed and legibility. Less visible colour combinations of text and background were read more slowly than the more contrasting or visible ones in both typefaces. At both typefaces, it was seen that at a slower reading speed, more fixations were needed and vice-versa. A transitional typeface gave a faster reading speed than a sans-serif typeface. An appropriate contrast, colour combination and used typography can facilitate legibility on displays. Doi: 10.28991/esj-2020-01243 Full Text: PDF

Authors: Pilvere-Javorska Aija , Pilvere Irina
Published: December 2020

Public financial markets are crucial in the access to the funding and as a platform for investments to the investors in today’s world. Nordic European Union countries such as Sweden, Finland and Denmark are considered to have advanced and well-developed stock markets, while neighboring three Baltic States have rather small stock market. Backbone of the stock market are there listed companies. In this analysis authors attempt to analyze 510 Nordic countries listed companies’ absolute value indicators using factor and cluster analysis and to compare results with similar analysis of the Baltic States. Factor and cluster analysis revealed the homogeneity of Nordic countries stock market listed companies’ absolute values, authors obtained three complex factors, explaining 89% of dispersion within the indicators, which in turn resulted in being able to obtain the portrait of Nordic States stock market listed company. Similar results were obtained for Baltic States listed companies, though on different scale. Authors have not seen as detailed analysis of Nordic Stock market on the level of listed companies financial statement analysis. Time period covered in this research of the financials are from 2004 to 2018. The analysis could be beneficial for other researchers focusing on the Nordic region stock market companies and also to the policy makers in the Baltic States, how the neighboring well-developed countries indicators could be interpreted and obtained results used for the enhancement of Baltic States stock market. Doi: 10.28991/esj-2020-01244 Full Text: PDF
Breakthrough on Routine Service Cycle Time Improvement – Leap Frog Concept, Duri Field, Indonesia
Authors: Irawan R.
Published: December 2020

Leap frog concept was created to address the loss of single joint rig agility and drive the cycle time average lower than ever. The idea is to move the preparation step into a background activity that includes moving the equipment, killing the well, dismantling the wellhead and installing the well control equipment/BOP before the rig came in. To realize the idea, a second set of equipment is provided along with the manpower. By moving the preparation step, the goal is to eliminate a 50% portion of the job from the critical path. The practice is currently performed in tubing pump wells on land operations. However, the work concept could be implemented for other type of wells, especially ESP wells. After implementation, the cycle time average went down from 18 hours to 11 hours per job, or down by ~40%. The toolpusher also reports more focused operations due to reduced scope and less crew to work with, making the leap frog operation safer and more reliable. Splitting the routine services into 2 parts not only shortened the process but it also reduces noise that usually appear in the preparation process. The team are rarely seen waiting on moving support problems that were usually seen in the conventional process. Having the new process implemented, the team had successfully not only lowered cycle time, but also eliminated several problems in one step. Other benefits from leap frog implementation is adding rig count virtually to the actual physical rig available on location, and also adding rig capacity and completing more jobs compared to the conventional rig. In other parts, leap frog faced some limitation and challenges, such as: limited equipment capability for leap frog remote team to work on stuck plunger, thus hindering its leap frog capability, and working in un-restricted/un-clustered area which disturb the moving process and operation safety.
An Innovative Well Intervention for Production Optimization in Depleted Gas Reservoirs Thru Coil Tubing
Authors: Wijayanto D.
Published: December 2020

Coil Tubing operated in NL wells, South Sumatera because of depleted reservoir pressure. Objective of coiled tubing operation are sand clean-out and acid stimulation to restore well productivity. Previously in NL wells has used a snubbing unit in intervention well but the results were not good. Formation damage was suspected due to packer fluid introduced into formation during snubbing job. Production optimization in brownfield is required to extend the economic producing life of the field using cost-effective and low-risk technologies. Well stimulation is generally proposed to enhance well productivity by acidizing treatment. Acidizing in sandstone applied in Medco to improve well productivity. But loss problem got in conventional rig operation during killing well in low reservoir gas well. Coiled tubing (CTU) can solve the problem and can operate without killing the well. Recipe acid HCl 15% get optimum in solubility test around 28-31%. Coiled Tubing Operation applied pulsonic method to get optimum result. After CTU Job (clean sand out & acidizing), well productivity improved refer to gas rate and flowing well-head pressure (FWHP) monitoring. Initial gas gain was more than 2.5 MMSCFD from 2 wells (NL-X1 and NL-X2) that were treated with CTU acid stimulation. Gas cumulative is around 176 MMSCF (3 months production) and still counting. Further evaluation will be conducted by performing complete well test (transient analysis). As conclusion, coiled tubing operation has proven to become effective well intervention in depleted gas wells to improve production optimization and open the opportunity to unlock potential in other wells which experiencing similar challenges. This paper shares case study, how to develop acid stimulation strategy covering guideline in acid selection and deploy acid without killing well in South Sumatra.
Geomechanical Modeling and Equivalent Circulating Density (ECD) Management- An Integrated Approach for Successfully Drilling and Managing Losses in Highly Depleted Sands
Authors: Chatterjee A.
Published: December 2020

A mature field in offshore Sarawak, Malaysia, contains multiple reservoir cycles interbedded with weak shale and coals. Production from these reservoirs caused significant pressure depletion, as well as reduced fracture gradient and a narrower drilling mud weight window. An integrated approach among the multi-disciplinary team was required in the well planning process to maintain the planned drilling and completion costs. An improperly weighted mud may induce wellbore instability in weaker, but normally pressured, formations or mud losses in the heavily depleted reservoirs. Globally, mud losses are considered the most expensive well control operation. Hence, successful drilling and managing losses through depleted sands requires a comprehensive geomechanical modeling and wellbore stability analysis. A field scale geomechanical model was developed and validated using data from exploration and development wells from different phases of drilling in the study area. The stress path factor (SPF), which determines the reduction in fracture gradient with pore pressure depletion is crucial for defining drilling mud windows, is difficult to constrain in the absence of measured formation fracturing data in virgin and depleted reservoirs. A mud loss event in the depleted zone from a recent drilled well and regional information were used to estimate the range of SPF in the study area. Recorded bottom hole pressures from pressure while drilling (PWD) data suggested that the maximum equivalent circulating density (ECD) recorded was close or within the depleted section. The loss event was associated with reduced fracture gradient due to depletion from its pre-depleted range. This paper describes how geomechanical evaluation with effective well drilling practices and fit for purpose-drilling fluids have helped drilling through depleted reservoirs with ECD management. At the end, it shows a comparison of the predrill wellbore stability mud weight estimates with the actual mud weights used to successfully drill and complete the planned wells.
Structural Evolution Using Seismic Low Frequency Magnitude Approach: A Case Study on Defining Strike-Slip Development in West Natuna Basin, Indonesia
Authors: Riandini P
Published: December 2020

West Natuna Basin (WNB) is located in the centre of Sunda Shelf in South China Sea; bordered by the Sunda Shelf's basement to the south, the Natuna Arch to the east, and the Khorat Swell to the north. Tectonic evolution of the WNB has imparted a complex structural history of extension, compression and wrenching related to Cenozoic regional tectonic events, for which the structural evolution reflects a history of Late Eocene-Early Oligocene rifting and Middle-Late Miocene inversion. The regional strike-slip movement that associates to the Three Pagodas Fault System has long been recognised at WNB. However, the understanding of this strike-slip behaviour has not previously been investigated despite its important role in reservoir mapping. This study aims to demonstrate how new approaches of seismic attributes analysis combined with structural evolution through palinspastic reconstruction will define the structural geometry as a key point for fault relationship in the production field. Structure map and cross section are generated by integrating wells data and 3D seismic to identify structural trends. Seismic low frequency magnitude has been generated as an attribute to define faults through Spectral Decomposition method. As the faults feature on the seismic are more related to low or even absent of energy, these attributes provide robust attributes to identify four morphology in study area that represent different structural geometry and history. Seismic interpretation shows the structure commences in the early part of the Late Eocene that developed as NE-SW rifting. The rifting is initiated due to creation of pull-apart basins, as part of the WNW-ESE sinistral strike-slip fault development. The major sinistral strike-slip development was accommodated by collision of India that causes onset of rotation of Sundaland. In relation to the oblique NNE-SSW compression, Middle-Late Miocene inversion follows the post-rift deformation. This condition accommodates the development of NW-SE right lateral strike-slip on the marginal fault and result in N-S trending horsetail structure development that plays a role as an essential structure for reservoir trap.This research verifies that the combination between recent re-evaluations of the 3D seismic and its attributes can identify more detailed fault positions to generate better definitions of fault patterns. Therefore, palinspastic restoration becomes one of the classic approaches that brings further comprehension of the fault pattern’s structural evolutions, which leads to the site-development and production’s improvements.
Understanding The Mesozoics Beyond Basalt: A Case Study Of Sub-Basalt Imaging
Authors: Sengupta S.
Published: December 2020

The Deccan Volcanic Province of India is considered as one of the largest basalts-covered regions in the world, formed due to extensive outpouring of basaltic lavas during Deccan volcanism (∼65 Ma). The sedimentary sequence below the flood basalt is mainly characterized by Mesozoic strata with a varying thickness of 1000 m to 2500 m. It is considered that requisite heat generation due to Deccan Trap volcanism soon after the Cretaceous sedimentation may have acted as a catalyst in hydrocarbon potential in this area (Vardhan et al. 2008). However, it is essentially unexplored because of the limitations of conventional marine streamer P-wave seismic acquisition in imaging the structures both intra-basalt and sub-basalt. The major challenges can be considered as follows: Strong reflections due to high impedance contrasts at the top (and bottom) of the basalts leading to significant loss of transmitted seismic energy; Scattering of energy due to large acoustic impedance contrast at top and bottom of the basalt; Generation of multiples, both surface-related and interbed, from the top and bottom of the basalt, and intra-basalt boundaries, masking genuine primary reflections at the pre-basasediments; Significant attenuation of seismic energy in the basaltic sequences due to its complex internal structure generally causing weak sub-basasignal; Low signal-to-noise ratio creating ambiguity in estimating accurate velocity model of subsurface. This case study demonstrates that, even with legacy marine streamer surveys, an appropriate workflow of combining suitable advanced technologies can help to overcome the long-standing challenges of sub-basalt imaging. The reprocessed data show clear uplift in the sub-basalt imaging and the inversion results validate the quality of the new data in relation to the well logs.
The Importance of Identifying the Evidence of Hydrodynamic Trapping for New Well Placement in Mature Offshore Stupa Field
Authors: Anshariy A.
Published: December 2020

To predict the hydrocarbon limit and new well placement for future development in the mature Stupa field, hydrodynamic trapping analysis is carried out to find a solution of “tilted” contact hypothesis. The static and dynamic data of 6 exploration wells and 12 development wells were used to recognize the evidence of hydrodynamic trapping. There are multiple pieces of such evidence for hydrodynamic trapping such as variation in fluid contacts, lateral reservoirs drainage and variation of water pseudo potential. This paper will describe identification of tilted gas – water contacts related to hydrodynamic trapping mechanism plays, to predict and map the tilted contact using “u” map as a limit of the field and how a tilted gas-water contacts map leads for opportunity to identify future well development. It is concluded that the hydrodynamic trapping is working in the Stupa field. A new limit of hydrocarbon accumulation as a result of tilted contact mapping using “U” map has significantly changed the field development strategy in the Stupa field. The West Stupa Panel has now become the new target location of future field development for prolonging the production life of the mature Stupa field. At the end of 2019, one development well was drilled at the north flank of West Stupa Panel and showed very good results, which unlocked the remaining gas potential of this panel. Following this positive result, 3 other wells are proposed to develop the remaining stakes in this panel. Identifying the evidence of hydrodynamic trapping and mapping the tilted gas – water contacts had opened new opportunities for further field development in flank areas of the mature gas Stupa field.
Comparison of Interval Velocity and Inversion Velocity Usage to Build 3D Pore Pressure Models – Case Study: Ja Field, East Java Basin
Authors: Arief J.
Published: December 2020

Pore pressure analysis is one of the stages that needs to be done before drilling and it is intended to determine indication of overpressure zones that may endanger the drilling phase. Pore pressure analysis could be done with various variables from well and/or seismic data. This study is conducted at the JA Field, East Java Basin, and focused on the claystone interval of the Ledok – Ngrayong Formation. This study will focus on interval velocity and inversion velocity in the claystone formations, which is typically showing more sensitivity to heterogeneity in such conditions. Besides mapping overpressure zone indications, this study was conducted to determine the sensitivity of the velocity variables in analyzing pore pressure and to make 3D pore pressure distribution models, where in this study interval velocity and inversion velocity were used. In addition to using the 1D pore pressure models from Well A1, Well B2 and Well C3 as a comparison, a blind test was also carried out to validate whether the two 3D pore pressure distribution models qualitatively represented the JA Field. From the pore pressure analysis results, both on the 1D and 3D models, which were carried out based on the Eaton (1975) method, it is known that there is an indication of the overpressure zone in the Wonocolo Formation with the top of overpressure zone depth at 5900-6200 ft. The 3D pore pressure models showed the overpressure zone distribution is marked by the significant color changes tendency in the center of the study area. Qualitatively, the use of interval velocity and inversion velocity in creating the 3D models appears in the distribution of different pore pressure values. However, the two 3D pore pressure models have generally represented the JA Field pore pressure distribution as evidenced by the blind test result.

Published: December 2020

Erratic power supply is a serious problem to most part of Rivers State, Nigeria in general and Ikwerre Local Government Area in particular. This situation does not only halt social and economic development of the area but has also given birth to other social vices such as arm robbery, kidnapping, and other criminal activities. Renewable energy is an alternative form of energy aim at alleviating the problems of erratic power supply. It is generally considered as the cleanest form of energy. Solar photovoltaic is a type of renewable energy which derived its energy from the sun. The construction of solar plant requires the selection of suitable location for the generation of optimal energy. The purpose of the study is to determine suitable locations in Ikwerre Local Government Area, Rivers State to site solar photovoltaic plant using multi-criteria analysis (MCA) in ESRI’s ArcGIS. The dataset used for the determination of the optimal sites include; solar radiation and slope map produced from digital terrain model (DTM), pipeline, road network, land use/ cover map, soil map, and settlement. The datasets were converted to raster and reclassed into six classes for the purpose of data integration. The datasets were weighted according to their relative importance in the weighted overlay tool. Solar radiation has the highest percentage influence 40, followed by proximity to pipeline and road network which are 15 each. The model produced four suitability classes ranging from poorly suitable to highly suitable class. Highly suitable class has an area of 10139.87ha with 548 polygons, representing 15.78% of the study area. Further analysis was carried out using highly suitable class and settlement layer, it was found that three (3) optimal sites were obtained as most suitable for sitting solar plant. The three polygons were located in the region with very high solar radiation, accessible to road and away from built-up areas. The above results suggest the usefulness of GIS in site selection, particularly in sitting solar photovoltaic plant. It is recommended that further study should include transmission line which was completely omitted in this analysis due to inability to get the shapefile from the ministry of power.

Plastic industry has contributed significantly to the current state of environmental damage because the polymeric materials used so far in various applications are not biodegradable. Thus, the need for viable and sustainable solutions to reduce the environmental impact and have better performance than the options currently available. In this regard, biodegradable polymers emerged as one of the solutions to cushion impact of plastics waste disposal on the environment. Cassava peels were dried and made into powder, which was used for this study with Bacillus safensis FO-366(T). After 48 hrs of incubation the pellets were extracted and purified with chloroform. The pellets were dried and characterised. The FTIR and GCMS revealed the presence of 3HD methyl ester as the prominent monomers of PHA. The blends showed better mechanical properties than PLA and PE. This study revealed the potential of cassava peels as a carbon source for production of biodegradable polymer.

Published: December 2020

The polycondensation of a silane derivative such as aminopropyltrimethoxysilane (ATMS) in the presence of nucleic acids has never been investigated. Our group has previously demonstrated that in chloroform ATMS hydrolysis and polycondensation were faster when the reaction were carried out in the presence of double stranded DNA (146 bp). The results showed that the kinetics of ATMS hydrolysis was affected by the base type used, a fast hydrolysis reaction rate being observed with nucleotide molecules containing adenosine group, and that in the absence of water the amino group of deoxyadenosine units, and not the hydroxylic group of the sucrose residue, can react with ATMS methoxy groups. The present work was initiated aiming at providing a better understanding of this effect. It was observed that the polymerization degree of oligodeoxyadenylate has a clear impact on the kinetic of reaction this effect being as much important as the polymerization degree of the oligodeoxyadenylate was high. Structural investigation by molecular modeling showed that this enhanced reactivity can be explained by conformational effects. Altogether, these results are accounted for assuming that DNA can act as a specific template for ATMS polycondensation, in organic medium such as chloroform, opening the way to possible DNA encapsulation, and a new way for DNA chemical modification in organic solvent.

The overall objective of this study was to evaluate the hemolysing action of Naja nigricollis venom on rabbit blood. To carry out this study, three batches of three rabbits were formed with two control batches and one experimental batch. Each control lot is composed of three rabbits (males or females) while the experimental lot is composed of two males and one female. Each rabbit from the control lots was separately collected in the purple tube (EDTA) and transported to the laboratory for analysis. The rabbits from the experimental batch were also collected distinctly a few minutes after the injection of the venom of Naja nigricollis for the analysis of haematological parameters. However, before the analysis of the hematological parameters of the rabbits from the control and experimental batches, an in vitro hemolysis test of Naja nigricollis venom was performed to verify its hemolysing power. The results showed that Naja nigricollis venom has a dose-dependent in vitro hemolysing power. As for the haemogram, it revealed that the venom of Naja nigricollis has a decreasing effect on blood cells (red and white blood cells), on haemoglobin and on haematocrit, and an elevation on MGVs thus promoting anaemia.

Twenty eight male rats randomly divided into 4 groups and weighing 131-214g were used. While the animals in group 1 (control) received food and water only, those in the study groups 2,3&4 respectively received 25mg/kg, 50mg/kg and 100mg/kg of Sildenafil citrate orally, daily for 4 weeks. All animals were sacrificed and blood samples collected by cardiac puncture for analysis of biochemical parameters. The rats Liver, kidneys and hearts were subjected to histopathological tests. Study results showed no changes in food consumption, fluid intake, body weight and relative organ weight of the animals. The animals in group 4 showed significant increase in mean Lactate dehydrogenase and Aspartate aminotransferase ⃰(P<0.05) compared to control. Mean levels of creatinine was significantly higher among group 4 animals ⃰(p<0.05) but not significantly high among the animals in other groups. Mean Na+ and Cl- level were significantly high among the animals in group 4 ⃰(p<0.05). Although no histopathological changes were observed in the heart of the rats in groups 2,3 and 4, there were significant increase in serum levels of Na+, K and Cl- of animals in group 4 which could have affected their heart owing to fatigue.
