Published: February 2020

One of major component of operating system is task scheduling for the optimum utilization of the resources. Round Robin had been an effective task scheduling method so far, but it has certain limitations. It uses static time quantum which sometimes leads to starvation. The proposed Optimised Round Robin is a modified version of the existing Round Robin scheduling which results in better average time and average turnaround time and overall increase in the performance. The comparative analysis is being done that indicates ORR gives improvement in the system performance.

Published: February 2020

With the advent of the Internet growth worldwide, we need to have a protocol which is faster and provides a better support for the following problems:

Faster Connection Establishment Time
Good Congestion Control
Connection Migration
Good Error Correction

One of the key aspects taken under consideration was current scenario of connection establishment time whenever a website is requested and poor video buffering over existing Internet Connections.
The prime objective is to create a proxy server which routes the incoming connection requests to QUIC supported libraries if the client supports QUIC. If the client does not support QUIC then it routes the incoming request to existing web server which can then handle the request using TCP. After creation of the proxy server a website has to be created using which we can test various aspects of the QUIC protocol.

Published: February 2020

Lemon grass (Cymbopogon winteriatus) has been widely acclaimed to possess therapeutic, cosmetic and insecticidal activities. This study was conducted using a field controlled trial by human volunteers to confirm the effectiveness and applicability of locally-produced Lemon grass oil as a mosquito repellent and adulticidal agent for the prevention of mosquito-borne diseases in Nigeria. Volatile oil was extracted using petroleum ether as solvent while olive oil was used as oil base. The study was conducted between September and October 2017 and made use of 12 volunteers across three locations. The lotions were applied on exposed body parts of the volunteers and they worked three shifts daily. The biting rate, percentage repellence complete protection time and whole night protection were measured and recorded. Topical application of each lotion reduced the biting rate of mosquitoes across the three locations, with the 60% (v/v) exhibiting higher impact of 341 vs 32; 438 vs 44 and 388 vs 33. The 60% (v/v) formulation also had the highest percentage repellence of 91.92% at Location I, offered a whole night protection against mosquito in location I and O and offered a Complete Protection Time (CPT) of 21.6, 18.93 and 20.8 respectively across all three locations. There was a significant statistical association r=0.95 (p<0.05) between concentrations of the Lemon grass oil formulations and mean duration protection time against mosquitoes. All formulation exhibited adulticidal activities, with the 60% (v/v) formulation having higher impact, causing fast immobilization or paralyzing effect on some mosquitoes that were at close range to treated volunteer’s body. The study concludes that volatile oils of Lemon grass possess mosquito (A. gambiae and An. funestus) repellent and adulticidal effects, especially at higher concentrations and can be used to reduce human-mosquito contacts and hence mosquito-borne diseases and irritation caused by their bites.

A Novel Nanotube/VES-Based High Temperature High Pressure Fracturing Fluid
Authors: Afra Salar , Samouei Hamidreza , Mahmoudkhani Ramtin , Nasr-El-Din Hisham 
Published: February 2020

Abstract
Viscoelastic surfactants (VES) were introduced to apply in hydraulic fracturing fluids as a proppant carrier in order to replace polymers which possess high potential for formation damage. Yet, VES technology is limited by its low thermal stability and high leak-off behavior in high permeability formations. This study aims to design a novel VES based hydraulic fracturing fluid assisted by functionalized carbon nanotubes (CNT) to enhance its rheological properties and extend its thermal stability.
Two types of VESs were tested in the present study. Viscosity measurements were conducted on the VES/CNT system with different concentrations of CNT to characterize the rheological properties of the system. Thermal stability of tested systems were evaluated using Nuclear Magnetic Resonance (NMR) spectroscopy. To understand the nature of the VES interactions with nanotubes infrared (IR) spectroscopy was conducted.
The results of rheological measurements demonstrate that addition of trace amounts of CNT, 0.04 to 0.2 wt%, to the solution of 6 wt% VES would enhance the rheological behavior (viscosity and elasticity) of tested VES systems by 40%. IR spectroscopy experiment was carried out to determine the functional groups that are involved in the interaction of CNT and viscoelastic surfactants. These results denoted that amide is the main functional group that can interact with CNT through hydrogen bonding and causes alternation of micellar structures due to change in the repulsion forces between surfactants headgroups. These findings were further confirmed by the results of NMR analysis.
The nanomaterial-enhanced fracturing fluids based on VES exhibit numerous advantages over conventional polymeric or VES-based systems including high-temperature performance, non-damaging nature, and low additive loading.
Case Study: Barium Sulfate Scale Removal by Dynamic Underbalance
Authors: Mahmud Walid Mohamed , Ermila Mansur 
Published: February 2020

Abstract
Petroleum wells producing water are likely to develop deposits of inorganic scales that may form near the wellbore and may plug perforations, coat casing, production tubulars, valves, deteriorate pump performance, and affect downhole completion equipment. Scales form and precipitate because the solution equilibrium of water is disturbed by pressure and temperature changes, dissolved gases or incompatibility between mixing waters. If scale formation and precipitation are allowed to proceed, scaling will limit production, eventually requiring abandonment of the well. In order to remove the effects of scale on production after a well undergoes sharp or early decline in production, it is essential to first determine which scales are forming and where they are forming. Some of this information can be reliably inferred from computer simulation procedures or by running calipers down the wellbore and measure decreases in the tubing inner diameter so that the scale can be physically detected. Gamma ray log interpretation may also be used to detect barium sulfate scale because naturally radioactive radium precipitates as an insoluble sulfate with this scale. Scale remediation techniques must be quick and nondamaging to the wellbore, tubing, and the reservoir. If the scale is in the wellbore, it can be removed mechanically or dissolved chemically. Selecting the best scale-removal technique for a particular well depends on knowing the type and quantity of scale, its physical composition, and its texture. Mechanical methods such as Dynamic Underbalance Pressure (DUP) technique are among the promising methods of scale removal in tubulars and across perforations. The purpose of this work is to present a case study of removing barium sulfate (BaSO4) scales from perforation tunnels utilizing dynamic underbalance technique. Wells from a North African oil field were selected for designed and optimized dynamic underbalance treatments to remove barium sulfate scales that precipitated in the perforation tunnels, preventing hydrocarbons flow from the formation to the production tubing. Gamma ray log and production logging tool were used before the treatment to detect and evaluate the type of scale and the intervals affected. Then the same tools were used after the treatment to assess stimulation taking place in the wells. Data obtained from the treatment was used to develop a model for predicting productivity index/inflow performance relationships. The dynamic underbalance technique successfully removed scale from all targeted wells, leading to an increase in oil production, without killing them (i.e. while still in production). Some wells achieved increase in oil production after the treatment of up to 65%. A predictive model was developed in order to estimate the performance of an underbalance scale removal treatment.

Abstract
Formation damage caused by organic and inorganic deposition particularly near and around wellbore, can substantially reduce the hydrocarbon production. In depleted oil reservoirs, when reservoir-driving forces are low and in declining stage, even small resistance can restrict the fluid flow resulting in loss of well productivity. Single stage chemical system was designed to restore the oil production of Malaysian oil producers that suffers with complex deposition problems. Extensive well selection activities and laboratory analysis were conducted prior to the well treatment.
This paper presents five case studies of treated wells that have been revived or boosted using the single stage chemical system. The well treatment consist of bull-heading a pill of pre-flush to facilitate the action of the main chemical system, followed by the main chemical, soaking for 24 hours and flow back the well. The well treatment job was completed successfully and safely with chemical cost saving of 40%. Post well treatment showed mixed results by instantaneous average production improvement of more than 400% for Well BK1, BK2 and BK3 and 26% production gain for Well BT2. The improved production sustained up to five months before a drop in production back to the old trend. Well BT3 wellbore damage was partially removed with less incremental in terms of gross production post treatment.
Primary hypothesis of short sustainability of the post well treatment is likely due to re-deposition of wax within the subsurface environment. Confirmation on this hypothesis is planned through slick line intervention. The instantaneous production gain highlighted the opportunity to replicate the technology with improved method by incorporating the inhibition chemical component to other potential wells that face similar deposition problem through proactive and preventive approach to ensure production sustainability and minimize the number of idle wells.
Reservoir Optimized Conformable Sand Control Completion in Oil Reservoirs
Authors: Li Weiming , Becerra Moreno Oscar , Malbrel Christophe 
Published: February 2020

Abstract
In recent years, shape memory polymer materials (SMP) and conformable sand control technology have shown significant advantages to conventional gravel packing or expandable screen solutions by providing the right combination of operational simplicity, total conformance, wellbore stability, and superior filtration required for long-term sand control and effective production inflow from reservoirs. Contrary to gravel packing that requires most of the wellbore length to be covered by screen to help dehydrate the slurry, the shape memory material may be placed selectively across the sweet spots. This has led to the question about how much of the intervals would need to be covered to get maximum productivity with the minimum SMP coverage, thereby impacting the overall completion cost. This paper utilizes reservoir modeling based well completion simulation to evaluate the impact of the SMP cartridge design configuration and reservoir properties on well production performance and provide optimized screen design solutions to maximize well production in oil reservoirs.
The reservoir model and horizontal well completion with the SMP cartridge modules are built in a reservoir simulator. Three categories of simulation cases are performed to investigate their impact on production: the number of cartridges per well segment, cartridge locations and spacing, and reservoir properties such as permeability and capacity.
These case results are compared with a base case where conventional standalone screen is used. The comparisons are used to define maximized and/or most economical sand control solutions. The results provide an effective optimization solution for maximized cumulative well production in oil reservoirs. In low rate wells, the simulation results also provide a more economical solution for cost sensitive well completions. Simulation results demonstrate significant production improvements with conformable SMP technology over conventional screens and provide a useful workflow to optimize completion designs for different reservoirs.
