Carbon Composite Rod Deployment System Enables Surveillance and Intervention Operations in Extended Reach, Maximum Reservoir Contact Wells that were Previously Inaccessible
Authors: Troup Duncan
Published: November 2019

Current drilling practice allows the drilling of wells whose horizontal drain sections maximise reservoir contact by remaining within a single productive zone. The well path may include sharp azimuth changes, which increases friction drag along the wellbore and precludes access and egress by conventional intervention techniques. This paper aims to demonstrate that a low weight, low friction and high strength carbon composite rod can reach the toe of even the most challenging profile of well.

A carbon composite rod of small diameter and containing an embedded electrical conductor is used in combination with standard tractors to deploy logging or other intervention tools into challenging wells. In such wells, the limiting factor for well intervention is the friction drag of the deployment system along the wellbore, especially where azimuth changes. The light weight of the rod combined with its extremely low friction coefficient means that drag is reduced to a minimum allowing access to TD while also ensuring safe retrieval without exceeding safe working load.

The carbon composite rod system has been used on a number of interventions that provide proof of concept for combined operations with a tractor in horizontal well systems. In each case the well and BHA was extensively modelled using the proprietary software designed specifically for the carbon composite rod system. In one case the objective was to maximise the payload that could be conveyed rather than the absolute depth achieved. Following extensive modelling including tractor performance, a toolstring measuring 459ft and weighing 7,260lbs was selected and run successfully in a horizontal well. The predicted behaviour compared very favourably to the data recorded during the job, confirming the accuracy of the models.

For an extended reach well where the objective is to obtain production and reservoir data all the way to the toe, the relatively small size and weight of the logging tools means that achievable depth is increased. A number of wells with challenging profiles that had never been successfully logged post completion were modelled using the latest software and operational parameters derived from recent experience. In each case, it was predicted that TD could be achieved and that the string could be safely retrieved from the well.

Demonstrating the convergence of predicted and actual performance of the carbon composite rod under a number of scenarios gives confidence in the validity of the models incorporated in the simulation software. Using these models to predict the performance in extended reach wells, especially in the cases where there are significant azimuth changes, will allow planning for rigless interventions where access or successful retrieval has been impossible up until now.

The study was conducted for Giant Gas-Condensate reservoir under Recycling mode in order to achieve the high condensate recovery and maintain the reservoir pressure by sectorize the reservoir into the different sectors. Especially with under-injection mode when no make-up gas is availableor sellable gas is required. The available amount of gas for injection should be properly distributed across the reservoir to maintain the reservoir pressure where it is most required and same time to prevent the early gas breakthrough. The study was aimed to sectorize the reservoir into thedifferent sectors which will lead to improve the reservoir management including the re-distribution of injection and full field development strategies.

The two approached have been created for sectorization: first approachwas based on the geological definition and second approach was based on the well level optimization. Many reservoir data have been utilized in this study including the surface facilities layout.

Initially, the available geological data such as Facies has been used to generate the above explained approaches. The actual tracer and other production/injection data used to confirm the above explained sectorization. Finally, the simulation model was re-build to address the sectorization. Moreover, several sensitives were simulated assume the 50%-80% RecycleRatio to come up with the optimum setup for gas injection distribution for the existing wells including the newly 2018 commissioned peripheral gasinjectors.

This work has resulted in positive outcome with few millions additional condensate recovery with zero investment. According the outcomes analysis the implementation plan is designed with allowable per each gas injector.

Published: November 2019

In 2017 the Abu Dhabi National Oil Company (ADNOC) made the decision to image the entire Emirate’s subsurface (onshore and offshore) with 3D seismic. In addition to covering areas little explored before, and refreshing old images with modern technologies, the goal is to explore specifically for unconventional resources and shallow gas. Imaging both shallow and deep targets, in areas known for low signal-to-noise ratio, requires intense field efforts and elaborate processing sequences. Acquisition started in late 2018 and is scheduled to finish early 2022 with a final image delivery two years later. This is an extremely tight timeline considering the almost 90,000 km2 to be covered.
Alteration of Wettability and Hydration Properties of Shale using Ionic Liquids in Water-Based Drilling Fluids
Authors: Ahmad Hafiz Mudaser , Kamal Muhammad Shahzad , Murtaza Mobeen , Khan Sarmad , Al-Harthi Mamdouh
Published: November 2019

Hydration of shale formations during drilling operations have adverse effects on wellbore stability. The shale hydration resulted from the interactions between drilling fluid and swelling clay contents in the shale formations. This paper addresses the improvement of wettability and hydration properties of shale to enhance the wellbore stability during the drilling operations. The novel ionic liquid-based drilling fluids were used to alter the wettability and hydration properties of shale. The novel ionic liquid based drilling fluid was developed by blending various ionic liquids and drilling fluid additives such as filtration control agent and rheological modifier. The rheology and filtration related properties of the base drilling fluid and its modified version with ionic liquids were determined. Shale inhibition characteristics of modified drilling fluids were evaluated by using real field shale sample and analyzing it with linear shale swelling test and hot rolling dispersion test. Two different ionic liquids (IL-1, IL-2) were deployed in the formulation of drilling fluids with a concentration of 0.05%. The conventionally used shale inhibitor KCl was also used in the formulation of drilling fluid with the concentration of up to 2%. The results of modified drilling fluids were then compared with the base drilling fluids prepared by mixing bentonite and cationic polymer (polydadmac). The rheological experiments showed that the addition of KCl and ionic liquids in the base drilling fluid resulted in a decrease in rheological properties. The filtration experiments also showed that filtrate volume has increased with the addition of KCl and ionic liquids in the drilling fluids. The hot rolling shale recovery experiment was performed at 65°C and superior shale recovery was observed with the synergistic effect of B/IL-2/K drilling fluid. Linear swelling of shale was assessed over a time period of 10 hours and minimum linear swelling of shale was observed with B/IL-2/K drilling fluid which indicated that the ionic liquid in the drilling fluid chemically interacts with the shale surface and makes it hydrophobic in nature which limits the interactions of water with shale. This use of novel ionic liquid-based drilling fluid enhances the borehole stability by modifying the shale surface and resulted in improved wellbore stability. The novel drilling fluid also has superior rheological, filtration properties and salt tolerance.
Novel Internal Coating System for High Concentration H2S Environments
Authors: Lauer Robert
Published: November 2019

Traditional internal coating systems relied on phenolic, novolac, epoxy or blended resin systems. These tended to provide good barrier properties in the environments they were developed for, but as with all materials, there were limitations. One of those limitations that had to be overcome during the development and application process was that during the curing process, they can tend to shrink, so greater surface preparation processes must be followed to ensure that the system adhesion far outweighs the residual stress in the coating system. In sweet applications, this residual stress offers little to no effect on a properly applied coating system provided its design parameters are not exceeded. In the presence of higher concentrations of hydrogen sulfide, there can be a negative effect on the adhesion of most of these resin type coating systems allowing the residual stress to play a role in blistering and disbondment. A new and novel resin system has been developed that does not shrink during the curing process and can be applied as a primer-less system. Coatings developed with this new resin, benzoxazine, allows the coating system to maintain good adhesion and barrier properties in H2S concentrations two to three times greater than the current leading H2S resistant coating systems on the market today. This paper will outline the technology behind this new resin system as well as the overall properties of the coating being delivered to market.

Subsea manifold is a flow-routing subsea hardware (subsea flow router) that connects between subsea trees and flowlines. It is used to optimize the subsea layout arrangement and reduce the quantity of risers connected to the platform, the new engineering technology of subsea manifold to be studied in this paper. From the perspectives of safety, economy, constructability, installation, operability and maintainability, it is proposed to divide the subsea manifold into three parts: manifold module, protection structure module and foundation module, thus forms the new split-type subsea manifold engineering. On the basis of analyzing the functional requirements of subsea manifolds, the method of manifold design and piping stress check is given herein. The protection structure design mainly involves protection against dropped object impact, fishing nets and dropped object. The structure design and strength checking method of dropped objects impact and trawl-board impact are also given. There are mainly two types of foundation for subsea facilities: mudmat and suction pile. Mudmat is more cost effective, hence it is the preferred solution. The design calculation method of mudmat is given (including vertical bearing capacity, torsional resistance, sliding resistance, overturning resistance, settlement calculation, skirt penetration capacity). Finally, the three modules are combined to form a new split-type subsea manifold design, which has been successfully implemented in South China Sea, providing a reference for the application of the new split-type subsea manifold.

Published: November 2019

The application of CO2 foam has caught overwhelming attention for fracturing shales. In applications, high foam deterioration and insufficient viscosity at operating conditions are the major concerns associated with foam fracturing process. In this study, polymer-free CO2 foam possessing high stability has been presented through chemical screening and optimization under HPHT conditions. Initial screening was performed by conducting a series of foam stability experiments considering different commercial anionic surfactants, concentration, and foam stabilizer addition using FoamScan instrument. Foam rheology study was then performed by considering the similar investigated factors under fracturing conditions using HTHP foam rheometer. All the tested solutions were prepared in fixed brine salinity and HPAM polymers with different molecular weights were used in evaluation of the performance of the designed polymer-free foam in term of foam strength. In comparison with other types of surfactant, alpha olefin sulfonate (AOS) exhibited the best foam stability and viscosity at testing conditions. The optimum AOS concentration providing the best performance was found to be 5000 ppm and its combination with 5000 ppm of foam booster (betaine) further increased AOS foam longevity. An improved result on foam stability and viscosity was not obtained by increasing surfactant concentration. Results on foam rheology reveals that CO2 foam generated in the presence of different molecular weight classical HPAM polymers could not provide significant increment in foam viscosity under experimental conditions. It was observed that these types of polymer underwent degradation due to some unfavorable mechanisms which will be expected to negatively affect its performance during fracturing process. On the other hand, polymer-free CO2 foam was found to produce a higher stability and relatively equally high viscosity compared to polymer-stabilied CO2 foam without experiencing degradation at high pressure and temperature conditions. Therefore, based on this study, it is recommended to use polymer-free foam for fracturing shales application. The use of formulated polymer-free CO2 foam which has high stability and viscosity will lead to improved fracture cleanup, minimized formation damage and pore plugging, and efficient proppant placement which will ultimately enhance gas recovery from unconventional shales.

Published: November 2019

Background The use of drugs beyond their authorisation label, i.e. off-label-use, is common practice in palliative care with over 70% of off-label-use having little or no scientific support. Recommendations for off-label-use are essential to increase the safety of drug therapy and thus patient safety. The aim was to develop a guide for preparing and consenting drug-specific recommendations for off-label-use in palliative medicine.Methods Group Delphi Study with three rounds and a prior online survey. Participants represented professional groups working in palliative care involved in direct patient care and/or drug management (doctors, pharmacists, nurses) and various care settings (inpatient/community, university/non-university). Furthermore, representatives of relevant professional associations, experts with academic, non-clinical background and experts with international expertise were invited.Results For the preliminary online-survey 18/20 invited participants returned 18 questionnaires. Six domains, including identification of drugs, drug uses, assessment of evidence, formulation, consensus and updating of recommendations were generated and eventually 22 statements were included in the Group Delphi process. 15 experts participated in this consensus process. In combination with the survey results, consensus was achieved over a 28 statements after 3 Delphi rounds.Conclusions The resulted systematic approach for preparing and consenting drug-specific recommendations for off-label-use will allow to develop such recommendations with transparent and reproducible monographs. This will help to increase treatment quality and patient safety as well as security of decision-making in palliative care. The developed guide is part of a larger project aiming to provide therapy recommendations for areas that have little or no scientific evidence to date.
Estimate of Hyperconjugation Strength in Alkylaromatics and Unsaturated Hydrocarbons Derived from Refractometric Data
Authors: Zaitsev Boris A.
Published: November 2019

:

A retrospective view of exaltation of refraction observed for many unsaturated
and aromatic compounds demonstrates that this physical phenomenon is undeservedly
considered only as a qualitative measure of conjugation. This mini-review discusses numerous
papers by the author that have been published earlier in inaccessible periodicals
and collections of scientific papers. Using a great number of illustrations, the author shows
that this parameter can be successfully used for quantitative estimate of resonance effects
in organic and polymer chemistry. The methods for derivation of strictly additive atomic
and group refraction constants are described; these constants were subsequently used as a
tool that allowed quantitative estimation of resonance effects in mono-, di-, tri- and polyalkylbenzenes,
alkylnaphthalenes, some alkyl derivatives of unsaturated hydrocarbons.
These effects cause strictly fixed increase in refraction of carbon atoms in different structural modifications
(graphene, fullerene, diamond) and in polycyclic aromatic hydrocarbons. The relevant results regarding quantitative
estimation of degree of steric inhibition of resonance in sterically hindered ortho-dialkylbenzenes, 1,2,3-
trialkyl-, 1,2,3,4-tetraalkyl-, and 1,2,3,4,5-polyalkylbenzenes accumulated by the author are summarized.

Authors: Yang Zhongyi , Hu Hanying , Zou Yuling , Luo Wenbluo , Xie Lin , You Zhipeng
Published: November 2019

Background:

Diabetic retinopathy (DR) is a common complication of
diabetes. This study investigated the effect of miR-7 in the regulation of cell proliferation
via the HoxB3 gene and PI3K/AKT/mTOR signaling pathways in DR.

Methods:

Human retinal pigment epithelial cell line (ARPE-19) cultured in normal
medium (Control) and high glucose medium (25mM glucose, HG) was transfected with
mimics NC (HG+ mimics NC), miR-7 mimics (HG+miR-7 mimics), inhibitor NC (HG+
inhibitor NC), and miR-inhibitor (HG+miR-7 inhibitor). The cells were assayed for
viability, apoptosis, and expression of genes.

Results:

HG reduced cell viability and increased apoptosis. However, miR-7 mimics
reduced the apoptosis. PCR results showed that miR-7 was significantly upregulated
after transfection with miR-7 mimics. The expression of Hoxb3, mTOR, p-PI3K, and p-
AKT was significantly downregulated at mRNA and protein levels after miR-7 mimics
transfection, while no difference was observed for PI3K and AKT expression.

Conclusions:

Our findings demonstrate that miR-7 regulates the growth of retinal
epithelial cells through various pathways and is a potential therapeutic target for the
prevention and treatment of diabetic retinopathy.

Published: November 2019

Background:

The advent of resistance-associated mutations in HIV-1 is a barrier to the success of the ARTs.

Objective:

In this study, the abundance of HIV-1 infection in Iranian children, and also detection of the TDR in naïve HIV-1 infected pediatric (under 12 years old) were evaluated.

Materials:

From June 2014 to January 2019, a total of 544 consecutive treatment-naïve HIV-1- infected individuals enrolled in this study. After RNA extraction, amplification, and sequencing of the HIV-1 pol gene, the DRM and phylogenetic analysis were successfully performed on the plasma specimens of the ART-naïve HIV-1-infected-children under 12 years old. The DRMs were recognized using the Stanford HIV Drug Resistance Database.

Results:

Out of the 544 evaluated treatment-naïve HIV-1-infected individuals, 15 (2.8%) cases were children under 12 years old. The phylogenetic analyses of the amplified region of pol gene indicated that all of the 15 HIV-1-infected pediatric patients were infected by CRF35_AD, and a total of 13.3% (2/15) of these children were infected with HIV-1 variants with SDRMs (one child harbored two related SDRMs [D67N, V179F], and another child had three related SDRMs [M184V, T215F, and K103N]), according to the last algorithm of the WHO. No PIs-related SDRMs were observed in HIV-1-infected children.

Conclusion:

The current study demonstrated that a total of 13.3% of treatment-naïve HIV-1-infected Iranian pediatrics (under 12 years old) were infected with HIV-1 variants with SDRMs. Therefore, it seems that screening to recognize resistance-associated mutations before the initiation of ARTs among Iranian children is essential for favorable medication efficacy and dependable prognosis.
Modulation of Gut Microbiota through Dietary Phytochemicals as a Novel Anti-infective Strategy
Authors: Mujawdiya Pavan K. , Kapur Suman
Published: November 2019

:

Quorum Sensing (QS) is a phenomenon in which bacterial cells communicate with
each other with the help of several low molecular weight compounds. QS is largely dependent on
population density, and it triggers when the concentration of quorum sensing molecules accumulate
in the environment and crosses a particular threshold. Once a certain population density is
achieved and the concentration of molecules crosses a threshold, the bacterial cells show a collective
behavior in response to various chemical stimuli referred to as “auto-inducers”. The QS signaling is
crucial for several phenotypic characteristics responsible for bacterial survival such as motility, virulence,
and biofilm formation. Biofilm formation is also responsible for making bacterial cells resistant
to antibiotics.

The human gut is home to trillions of bacterial cells collectively called “gut microbiota” or “gut
microbes”. Gut microbes are a consortium of more than 15,000 bacterial species and play a very
crucial role in several body functions such as metabolism, development and maturation of the
immune system, and the synthesis of several essential vitamins. Due to its critical role in shaping
human survival and its modulating impact on body metabolisms, the gut microbial community has
been referred to as “the forgotten organ” by O`Hara et al. (2006) [1]. Several studies have demonstrated
that chemical interaction between the members of bacterial cells in the gut is responsible
for shaping the overall microbial community.

Recent advances in phytochemical research have generated a lot of interest in finding new, effective,
and safer alternatives to modern chemical-based medicines. In the context of antimicrobial
research various plant extracts have been identified with Quorum Sensing Inhibitory (QSI) activities
among bacterial cells. This review focuses on the mechanism of quorum sensing and quorum
sensing inhibitors isolated from natural sources.
Synthesis, Antimicrobial Evaluation and Docking Study of Novel 3,5-Disubstituted-2-Isoxazoline and 1,3,5-Trisubstituted-2-Pyrazoline Derivatives
Authors: Ismail Ahmed H. , Abdula Ahmed M. , Tomi Ivan H.R. , Al-Daraji Ali H.R. , Baqi Younis
Published: November 2019

Background:

The frequent use of antibacterial agents leads to antimicrobial resistance,
which is one of the biggest threats to global health today. Therefore, the discovery of novel antimicrobial
agents is still urgently needed to overcome the severe infections caused by these putative
pathogens resistant to currently available drugs.

Objective:

The present work was aimed to synthesize and investigate the preliminary structureactivity
relationships (SARs) of isoxazoline and pyrazoline derivatives as antimicrobial agent.

Methods:

Target compounds were obtained in a multistep reaction synthesis and the antimicrobial
activity was investigated in several species; two-gram negative (Escherichia coli and Pseudomonas
aeruginosa), two-gram positive (Staphylococcus aureus and Bacillus subtilis) and one fungi
(Candida albicans), using cup-plate agar diffusion method. The most potent compounds were
docked into glucosamine-6-phosphate synthase (GlcN-6-P), the molecular target enzyme for antimicrobial
agents, using Autodock 4.2 program.

Results:

Herein, thirteen novel target compounds were synthesized in moderate to good isolated
yield. Based on the SARs, two compounds (2c and 5c) were found to be potent antimicrobial
agents on all tested targets, recording potency higher than amoxicillin, the standard antimicrobial
drug. Compound 2b identified as selective for gram-negative, while compound 7a found to be selective
for gram-positive. The hit compounds (2c, 5a, 5c and 5d) were subjected to a docking
study on glucosamine-6-phosphate synthase (GlcN-6-P). All hits were found to bind to the orthosteric
(active) site of the enzyme, which might represent a competitive mechanism of inhibition.

Conclusion:

The newly synthesized heterocyclic compounds could serve as potent leads for the
development of novel antimicrobial agents.
Breast Milk Stem Cell Survival in Neonate's Gut, Entery into Neonate Circulation and Adaption by the Body
Authors: Ghosh Amit
Published: November 2019

:

The stem cell exchange during pregnancy is thought to remain chimeras for life. Few studies
recently revealed that maternal transfer of viable stem cells to the offspring continues even after birth
during breastfeeding. Some of these stem cells are likely to be integrated into different organs (brain,
blood, kidneys, and pancreas) including neurons and insulin-producing cells in the pancreas to become
functional cells. This finding opens a new avenue for research on therapeutic uses of breast milk- derived
stem cells.

:

Recently Dr. Foteini Hassiotou used glowing mice, which were genetically modified to express a gene
called tdTomato that causes cells to appear red under fluorescence light. These mice were mated, and
their babies were swapped with the pups of another, unmodified mother mouse. The new pups suckled
the modified mouse and, as a result, obtained glowing red stem cells from breast milk. The study has
never been replicated in humans, so it is not clear yet if the findings apply to humans as in the case of
mice. However, the results of the study are the jumping-off points for future research on human breast
milk stem cells and their possible application in stem cell therapies. Additional studies are necessary to
understand the passage of human breast milk stem cells through the neonate’s GI tract, and passage to
the systemic circulation.
Dental Students’ Knowledge and Attitudes About Electronic Cigarettes: A Cross‐Sectional Study at One Saudi University
Authors: Natto Zuhair Saleh
Published: November 2019

There is limited information about what dental students know about the risks and effects of e‐cigarettes, and there is even less information regarding their attitudes about e‐cigarettes. The aim of this study was to assess dental students’ knowledge, education, and attitudes regarding e‐cigarettes and their confidence in discussing e‐cigarettes with patients. All fourth‐ to sixth‐year students registered at the King Abdulaziz University Faculty of Dentistry were invited to participate in this cross‐sectional study conducted during a three‐week period in December 2018. The focus was a comparison of never versus ever e‐smokers (“ever” meaning current or former e‐smokers). The response rate was 38.7% (193/498). Among the responding students, 43.2% (n=83) had ever used an e‐cigarette, and 11 (5.7%) reported being current users. Almost 95% (n=183) of the total participants said they did not feel confident about their e‐cigarette education in dental school. Students who had ever used an e‐cigarette said they were more confident discussing e‐cigarettes with patients than did students who had never used them and also demonstrated greater belief that e‐cigarettes lower the risk of cancer for patients who use them as an alternative to smoking traditional cigarettes (p<0.001). This study provides evidence of a gap in dental students’ attitudes and knowledge regarding e‐cigarettes, making it necessary to integrate e‐cigarette education into future curricula.

Published: November 2019

Early clinical exposure (ECE), defined as any interaction with patients prior to the portion of the curriculum when den‐ tal students spend most of their time at school as a primary provider, is a growing trend in curriculum reform across U.S. dental schools in the 21st century. The aims of this study were to characterize the types of ECE implementation in U.S. dental schools and determine if ECE correlated with earlier clinical competency assessments. In September 2018, the academic deans of all 66 U.S. dental schools were invited to respond to an eight‐item electronic survey about ECE at their schools. Representatives of 40 schools submitted complete responses, for a response rate of 60.6%. Among the respondents, 85% reported their schools started their principal clinical experience (PCE), the portion of the curriculum when students spend most of their time as the primary provider for patients, during the last quarter of Year 2 or the first quarter of Year 3. Respondents at all 40 schools reported offering some form of ECE as part of the formal curriculum, with shadowing and performing dental prophylaxis the most commonly of‐ fered types. No statistically significant associations were found between specific types of ECE and related Commission on Dental Accreditation (CODA) clinical standards for both formative and summative assessments. Although U.S. dental schools have been incorporating more ECE into their curricula over the past decade, these findings suggest that it has not led to earlier clinical competency assessments.

Published: November 2019

Reflection involves taking the time to deeply consider a past situation and examine areas of weakness or confusion. It allows identification of learning needs and the development of an action plan to improve future experiences. The aim of this study was to assess second‐year dental students’ ability to reflect in writing on a clinical rotation when prompted with a guided reflection template. The 76 second‐year dental students enrolled in a periodontics clinical rotation course at one U.S. dental school in 2016‐17 completed two reflective writing exercises during the semester. A total of 144 journals (after excluding incomplete journals) were analyzed individually by two evaluators following a rubric developed by Kember. This rubric combined Mezirow's seven levels of reflection into four categories: Habitual Action (HA), Understanding (U), Reflection (R), and Critical Reflection (CR). The first two categories are examples of non‐reflective thoughts, and the latter two are reflective. The two sets of journals were also compared. On average, the journals contained 0.2% HA, 15.9% U, 73.8% R, and 10.1% CR, averaging 16.1% non‐reflective thoughts and 83.9% reflective thoughts. Comparison of the students’ first journal submissions to their second showed that the first journals averaged a higher percentage of reflective thought than the second journals: 85.2% vs. 82.7%, respectively. However, the first journals showed a lower average percentage of critical reflection than the second journals: 9.3% vs. 11.3%, respectively. Overall, a high degree of reflection was found in these students’ journals after rotation in periodontics clinic, suggesting that reflective journaling can serve as a useful learning exercise to promote continual improvement during clinical training.

Intelligence for young children is very important for themselves and their social development, because if the intelligence of children develops well, it will be easier for them to get along with creating new things. Besides learning media has a very important role in the learning process. Media that can improve mathematical logical intelligence in children, one of them is the dice numbers. Based on observations shows that the logical-mathematical intelligence of students is still low. This study uses a quasi-experimental method using a non-equivalent control group design. Based on the calculation of the experimental class normality test that is 0.044 <0.05, so the data are declared not normally distributed. While in the control class the result is 0.200> 0.05, until the data are declared normally distributed. Therefore, because one class is declared not normally distributed, the data will be processed using the Mann Whitney test. The results of the Mann Whitney test in the experimental and control classes were 0.001 <0.05. So the conclusion is dice media can improve mathematical logical intelligence.Kecerdasan untuk anak usia dini sangat berperan penting bagi dirinya maupun perkembangan sosialnya, karena jika kecerdasan anak berkembang dengan baik maka akan memudahkan mereka bergaul juga menciptakan hal-hal baru. Selain itu media pembelajaran memiliki peranan sangat penting pada  proses belajar. Media yang dapat meningkatkan kecerdasan logis matematis pada anak, salah satunya yaitu dadu angka. Berdasarkan hasil observasi, kecerdasan logis-matematis peserta didik masih tergolong rendah. Penelitian ini memakai metode kuasi eksperimen serta memakai desain kelompok kontrol non-ekuivalen (the nonequivalent control group design). Berdasarkan perhitungan uji normalitas kelas eksperimen yakni 0.044 < 0.05, sehingga data dinyatakan tidak berdistribusi normal. Sedangkan di kelas kontrol hasilnya adalah 0.200 > 0.05, hingga data dinyatakan berdistribusi normal. Oleh sebab itu karena salah satu kelas dinyatakan tidak berdistribusi normal, data akan diolah memakai uji Mann Whitney. Hasil dari postes Mann whitney di kelas eksperimen serta kontrol adalah 0.001 <  0.05. Jadi kesimpulannya media dadu angka dapat meningkatkan kecerdasan logis matematis.
