Authors: ARSLAN Selçuk , TURALOĞLU Çağdaş , TURSUN Nihat 
Published: March 2019

Bu
çalışmanın amacı, yabancı ot kontrolünde kullanılan alev makinelerinde
kullanılabilecek ve ticari gaz memelerine göre daha uygun bir gaz memesi geliştirmektir. Bu amaçla, üç farklı meme tasarlanmış ve 1.0-3.0
bar aralığında basınç-debi karakteristikleri gravimetrik olarak belirlenmiştir.
Üç delikli 1 mm çaplı memenin (Tip1) 1.5-2.5 bar basınçlarda aralığında,
yabancı ot mücadelesinde genellikle gerekli olan 40-130 kg ha-1
propan (LPG) dozlarını uygulayabileceği bulunmuştur. Bu meme tipi, ticari gaz memesine
göre düşük dozlar için gerekli ilerleme hızını azaltmış, yüksek dozlar için
gerekli olanı ise yükseltmiştir. Böylece ticari gaz memesi için 2.0 bar
basınçta gerekli olan 1.8-8.1 km h-1 aralığındaki hız sınırı 3.5-6.5
km h-1 aralığına çekilmiştir. Yüksek dozlarda gerekli olan ilerleme
hızları biraz artırılmış olduğundan uygulamada özel imal edilen gaz memesi
kullanılarak alev makinesinin alan iş başarısının artırılabileceği bulunmuştur.
En düşük dozda ise ilerleme hızının düşürülmüş olması alan iş başarısını
azaltacak olsa da yabancı otların aleve maruz kalma süresi %20 kadar artacağı
için alev uygulamasının ısıl etkinliğini potansiyel olarak artıracaktır. Tip2
ve Tip3 memeler, delik çapları küçük olduğu için traktöre bağlanacak bir alev
makinesi için uygun bulunmamıştır. Sonuç olarak, yabancı ot mücadelesinde
kullanılacak alev başlıkları için daha uygun bir ürün (Tip1) elde
edilebilmiştir.

Biosimilar Agents for Psoriasis Treatment: The Perspective of Portuguese Patients
Authors: Azevedo Alexandra , Bettencourt Andreia , Selores Manuela , Torres Tiago 
Published: March 2019

Introduction: Biosimilars are highly similar copies of previously approved original biologic medicines. Their introduction on the market may yield cost reduction. The aim of this study was to evaluate the perspectives of psoriasis patients on biosimilar medications.Materials and Methods: We conducted a 14 questions survey of psoriasis patients receiving biological therapy and followed-up in a dermatology department of a Portuguese tertiary care hospital.Results: From a total of 108 patients included, 70.4% of patients did not know the definition of biosimilar agent and 76.6% of patients showed partial or total interest in using a biosimilar drug. Nearly 80% of patients partially or totally agreed in using a biosimilar drug in order to reduce healthcare costs with psoriasis treatment. However, the lack of studies in the European population and in psoriatic patients led most of the patients (72.2% and 75.0%, respectively) to somewhat or completely oppose to the use of biosimilars. Demographic variables, household income and type of current biologic therapy did not affect patient preferences.Discussion: Despite of the unfamiliarity of the respondents with biosimilars, most patients seem receptive to their use. Nevertheless, there are two issues of concern: i) the use of biosimilars that are not tested in a European population, and ii) its approval for psoriasis without trials in this disease. Thus, an immediate need exists for patient education about biosimilars.Conclusion: Biosimilars may increase patient access to biologic therapies. Improved communication and the involvement of patients in decision-making regarding biosimilars may increase their acceptance in future.

Severe Postpartum Coagulopathy Without Haemorrhage: A Case Report
Authors: Lérias-Cambeiro Muriel , Rodrigues Anabela , Taborda Inês , Lança Filipa 
Published: March 2019

Postpartum haemorrhage is an important health issue worldwide, and it can be caused by uterine atony, retained placental tissue, trauma or coagulation disorders. Although coagulopathy represents a rare cause, it is a significant contributor to postpartum haemorrhage with poor outcomes. Associated with high morbidity and mortality rates, postpartum haemorrhage demands prevention, prompt diagnosis and effective management. We describe a unique case of severe coagulopathy caused by underestimated blood loss during caesarean section without postpartum bleeding, in which transfusion requirements were thromboelastometry-guided. This case report depicts how an early multidisciplinary approach and patient-centred care in an obstetric emergency contributes to a positive outcome from a challenging situation, enabling the prevention of an imminent, catastrophic haemorrhage.
Novel Nano-Capsules for Oil Field Chemicals Delivery and Slow Release
Authors: AlJabri Nouf , Chang Yun 
Published: March 2019

Abstract
Chemicals in oil fields have shown a great potential for enhancing/improving oil recovery (EOR/IOR) beyond waterflood baseline. The objectives of this work are: (1) to develop a cost-effective method to deliver chemicals to deeper layers in reservoirs compared to conventional chemical operations, (2) to synthesize nano-capsules with improved stability under typical reservoir temperatures (80-110 °C), and (3) to demonstrate the gradual release of EOR/IOR chemicals over time at a given temperature within the above range. Multiple slow-release technologies were developed; (1) Nano-salt (2) liposomes and (3) nano-capsules. In the first method, nano-size surfactant salt particle that has a limited solubility can traverse the reservoir and deliver, over a long period of time, a constant concentration of surfactant was synthesized. In addition to surfactant salts, surfactant-loaded nano-capsules were synthesized by dissolving a known lipid formula in 20.0 mL chloroform, then, evaporating the solvent to form a dried lipid film. Acid nano-capsules for improving oil recovery operations were synthesized using In situ and interfacial polymerization. Scanning electron microscopy, an optical microscopy, dynamic light scattering, Inductive coupled plasma (ICP-AES), pH and surfactant electrodes were used to characterize the nano-capsules and dispersion. To assist the nano-platforms slow-release profile and the particles stability under reservoir conditions, the samples were incubated in oven at 95 °C. The nano-capsules’ slow-release and stability were monitored for several days. The liposomes contain 11 wt. % of PETRONATE® EOR2095 with particles’ average size of ~80 nm, the surfactant released was gradually increased over sixty hours. The acid nano-capsules contain 15 wt. % acid precursor with particles’ average size of 200 nm. The capsules release versus time curve showed that the release occurred when the temperature reached 95 °C, indicating that nano-capsules’ release is triggered by the temperature increment. The pH versus time release curve exhibits a gradual decreasing in the pH over six day indicating the acid precursor hydrolysis at 95 °C. Our results demonstrate the possibility of improving current chemicals flood via nano-encapsulation. The slow release technology may bring new potentials to the current hydrocarbon production operations.
Characterization and Comparison of Outcrop and Subsurface Unconventional Shale Samples

Published: March 2019

Abstract
Subsurface unconventional shale samples are always scarce. Outcrop analogs are often used as an alternative to enhance the understanding of the corresponding reservoir formation. One assumption is usually made that rock composition and properties between the outcrop and subsurface samples remain the same or similar, despite differences in their burial and diagenetic histories. This paper presents a comparative case study to investigate the similarities and differences in rock properties between outcrop and subsurface samples from the same formation.
Two subsurface and two outcrop samples from the Lower Silurian Longmaxi formation in Sichuan Basin of China were characterized to determine their mineralogical, geochemical, petrophysical, elastic and mechanical properties. Micro-CT images showed that one subsurface sample was drilled normal to the bedding, while other three samples were parallel to the bedding. Two subsurface samples differ in their mineralogy – the horizontal sample is clay-dominant, while the other one is predominantly comprise of quartz, dolomite and calcite minerals, very similar to two outcrop samples. All four samples are thermally immature and their Tmax is less than 435 °C. Subsurface samples have the highest TOC of 3.75% but relatively lower HI and OI. Other pyrolysis parameters are very similar between subsurface and outcrop samples. All samples have very low porosity of less than 2.5% and permeability of less than 9 nD, although subsurface samples have a relatively higher value.
The discrepancy in mineralogical composition, especially the clay content, results in different elastic and mechanical behavior of outcrop and subsurface samples. The subsurface sample is highly anisotropic in both compressional and shear wave anisotropy due to the large amount of clay minerals, while one outcrop sample exhibits the strong shear wave anisotropy only and the other one is almost isotropic. Subsurface samples have lower values of Young's modulus, peak stress, Mohr-Coulomb failure parameters and unconfined compressive strength than outcrop samples.

Published: March 2019

Abstract
The reservoir in discussion is a tight carbonate reservoir with low productivity and relatively under-developed albeit the huge in-place volumes. The expectation is that a detail reservoir characterization will provide insight on factors affecting reservoir productivity, spatial distribution of productive portion of the reservoir and offering solution to overcome reservoir tightness.
The case study discusses on how a comprehensive multi-discipline review unravels and presents a robust reservoir heterogeneity framework. A geological review that includes both depositional and diagenetic process is performed to understand distinct components/factors responsible for reservoir heterogeneity. Simultaneously, petrophysical assessment was performed to quantitatively define rock grouping based on porosity-permeability, capillary pressure and pore throat distribution in the log and core domain.
The multi-discipline observations were then reconciled to establish relationship between the process origin and the resultant product of specific group/range of reservoir petrophysical properties. The multitude of pore throat characters and its petrophysical properties were linked to the underlying geological processes. The established heterogeneity framework provides clarity on spatial distribution of the reservoir sweet-spot, factors controlling low productivity and the required mitigation.
The study provides a complete journey of unlocking tight reservoir potential. It illustrates the geological studies influence toward innovative completion technology selection, design, and execution to overcome reservoir challenge. The study is supported by recent drilling and test results, hence offering insight for adoption and lesson learned.
Application of High Performance Asynchronous Acoustic Wave Equation Stencil Solver into a Land Survey

Published: March 2019

Abstract
This paper describes the application of high performance asynchronous stencil computations for 3D acoustic modeling on a synthetic land survey. Using the Finite-Difference Time-Domain (FDTD) method, a parallel Multicore Wavefront Diamond-tiling (MWD) stencil kernel (Malas et al. 2015, Malas et al. 2017) drives the high performance execution using temporal blocking to maximize data locality, while reducing the expensive horizontal data movement. As absorbing boundary conditions, we use Convolutional Perfectly Matched Layer (CPML), which have to be redesigned to not interrupt the asynchronous execution flow engendered by the MWD stencil kernel for the inner-domain points. The main idea consists in weakening the data dependencies by moving the CPML computations into the inner-computational loop of the MWD stencil kernel (Akbudak et al. 2019). In addition to handling the absorbing boundary conditions, applying the asynchronous MWD with CPML kernels to a realistic land survey requires the extraction of the wavefield value at each receiver position. We revisit the default extraction process and make it also compliant with the overall asynchrony of the 3D acoustic modeling. We report performance improvement up to 24% against the standard spatial blocking algorithm on Intel multicore chips using the synthetic land survey, which is representative of an area of interest in Saudi Arabia. While these results concur with previous performance campaign assessment, we can actually produce and assess the resulting 3D shot gather accuracy. To our knowledge, this is the first time the effectiveness of asynchronous MWD stencil kernel with CPML absorbing boundary conditions is demonstrated in an industrial seismic application.
Data and Model Integration Challenges for Integrated Production Forecasting-Experience from Super-Giant Onshore Fields

Abstract
To optimize production of a supergiant field, operators require an integrated approach to production forecasting that incorporate subsurface models of multiple reservoirs, well performance, surface equipment and facility constraints. This helps asset managers plan and optimize production on a well-by-well basis to achieve maximum system deliverability. This paper addresses challenges of integrating huge amounts of data, model framework and automated workflows to identify opportunities in debottlenecking, production target sustainability and deliverability.
The integrated production system model involves a simplistic bottom-up approach, in which advanced integration of subsurface and surface elements was facilitated through automated workflows within a digital oilfield system. These automated workflows enable converting multiple reservoir simulation output files to a standard format and mapping of common well names in simulation outputs and in well and facility models. An event-controlled scheduling process in a single working environment enabled analysis of production targets in realistic facility situations for future time steps. The decline in reservoir pressure is modeled, with new well performance in facility model based on changing reservoir conditions.
This automated environment has been adapted to evaluate two giant onshore fields encompassing multiple reservoirs, thousands of wells and numerous distributed-process facilities. The forecasting process confirms deliverability of planned and sustainable production and identifies opportunities for additional field potential, thus facilitating CAPEX optimization for future well costs. The integrated asset forecast was successfully carried out over a five- year timeframe at monthly intervals. One of the most important results obtained from such a forecast simulation was obtaining the maximum feasible rates that can be expected from the asset for each month during the next five years. This collaborative solution has successfully demonstrated the value of data and software integration, and addressed the challenges in integrated production forecasting. The results prove that this is a powerful tool for short- and medium- term forecasting, enabling asset managers to plan field operations, drilling, workovers, and facility improvement projects
This paper describes an integrated production forecasting setup. The case study explains process steps, challenges, simplification and results. The modeling and integration process enables the asset operator to plan remedial subsurface and surface projects to sustain planned rates over time. The forecasting process helps in quick business decision making, thus minimizing uncertainties in deliverability of future production mandates and highlights production-enhancement opportunities.
Use of Geological Constraints in Multi-Mineral Modeling for Unconventional Reservoirs
Authors: Hao Zhang , Nora Alarcon , Freddy Mendez , Amer Hanif 
Published: March 2019

Abstract
Determination of mineral rock composition is an important part of unconventional reservoir formation evaluation because the mineral composition affects hydraulic fracture generation and propagation. Two types of models are usually used for mineralogy modeling—deterministic and stochastic. Both models apply mathematical representations of the logging tool responses; however, stochastic modeling has become more popular due to its consideration of random distributions in the predictor and target variables. Stochastic mineralogy modeling algorithms usually produce solutions by minimizing a function reflecting the differences between the measured and modeled responses. However, due to the non-uniqueness inherent in inversion methods, the solution may not provide petrophysically meaningful results. To avoid producing compromised results, the use of geological constraints is proposed to represent the geological relations between the unknown parameters (inversion variables), leading to a more meaningful mineralogy model.
The proposed algorithm incorporates probability functions to generate mineralogical solutions representing geologically and petrophysically sound results. The weight assigned to the penalties in the cost function depends on the probability function assigned to the constraints. Two models are presented using the proposed algorithm: a pyrite-anhydrite constraint based on the iron and sulfur ratio, and a K-feldspar-albite constraint based on the thorium and potassium ratio.
Data sets from several different shale plays, from across North America, are processed using the proposed algorithm. The mineral sets are complex and vary from one play to another. The results show excellent agreement with the available core X-ray diffraction measurements. The study demonstrates that the proposed constraints provide an effective improvement, in integrated formation evaluation, especially in unconventional reservoirs with highly complex mineralogy.
