Published: March 2017

Abstract
In the field of enhanced oil recovery the engineered/low salinity water injection (EWI/LSWI) is the latest and promising development. Several mechanisms describing the EWI/LSWI process have been suggested in the literature; however, there is no consensus on a single main mechanism for its effect on oil recovery. Wettability alteration is believed to be the main reason behind the incremental oil recovery; however several other possible mechanisms are also suggested. This paper investigates the effect of engineered water injection (EWI) on oil recovery from carbonate cores. The recovery predictions are based on numerical simulations using laboratory coreflood data.
The results show that heterogeneity effect on oil recovery history matching is more pronounced compared to capillary pressure effect. Moreover, an EWI model is proposed based on multi-ion exchange reactions for capturing incremental oil recovery by EWI in carbonates. The model includes other geochemical reactions, homogeneous (aqueous) and heterogeneous (precipitation/dissolution reactions), as well as the resulting wettability alteration in carbonates. Coreflood experiments are simulated and history matched using the proposed EWI model. This model can be used for oil recovery predictions and optimization in carbonate fields. This work provides more insight into the benefits of EWI and hence, supports new field applications.

Abstract
Unlike other types of inorganic scales, carbonate and sulphide scales are directly correlated to the in-situ concentration of acid gases such as CO2 and H2S, which influence the local pH and availability of reactive species. The common approach to sulphide and carbonate scale prediction often does not account for three phase CO2 and H2S partitioning at different temperatures and pressures along the system. This leads to the use of inaccurate compositions and pH values for the mineral scaling calculations.
In this paper, we apply a rigorous workflow (step-by-step procedure) based on a compositional PVT model to calculate molecular CO2 and H2S distribution, three phase relative volume changes, compositional changes and scale precipitation trends from the reservoir to the wellhead separation stage using commonly available surface field data, a full PVT software and a scale prediction software of user's choice.
A simplified version of the workflow was previously applied to high CO2 and H2S gas/condensate wells with production of condensed water only (Verri et al., 2016).
This paper focuses on the field application of our general workflow to North Sea oil wells with high water cut and medium H2S levels (≈2200 ppmv in the separator gas phase). By following this rigorous procedure and applying the concept of Maximum Dissolved Iron (MDI) we were able to provide accurate sulphide and carbonate scale prediction profiles from reservoir to separator.
The combination of reservoir, production and chemical engineering models using specific iterative processes (within the workflow) has provided a new and reliable step-by-step procedure for the prediction of combined sulphide and carbonate scales in oil and gas wells which can be implemented by anyone using any PVT and scale prediction software. However, in our ongoing work, we are building a model which incorporates all of this workflow by coupling together PVT/VLE models with our aqueous scale prediction software.
Geopolymer - Synthetic Based Mud Hybrid Cements for Primary Cementing and Lost Circulation Control

Published: March 2017

Abstract
Geopolymer, an aluminosilicate-based alkali-activated cementitious material, can be used as an alternative to Portland cement in oil and gas wells. While the current literature on geopolymers primarily focuses on the construction industry, this work was aimed at studying the potential use of novel geopolymers for well construction applications such as primary cementing and lost circulation control. It was recently discovered that hydroxide-activated geopolymers have the ability to solidify non-aqueous drilling fluids (NAFs, i.e. with synthetic or oil based muds) up to 60/40 geopolymer/mud ratio (by volume). The primary benefits of such a blend include better compatibility of the slurry with NAFs, reduced risk of poor cementation, inexpensive source material as well as an environmentally friendly on-site/in-situ disposal of NAFs. The rheological properties, short-term and long-term compressive strengths of the geopolymer/NAF blend can be tailored to any specific application. In this work, the effects of pressure, oil/water ratio variation and internal brine phase composition in the NAFs were systematically studied. Both liquid-form and solid-form sodium silicate activators were used to form silicate-activated geopolymers. The slurry design was targeted for specific applications. For lost circulation control, the geopolymer slurries were deliberately blended with non-aqueous drilling fluids to achieve rapid gelation and setting characteristics.
Combining a Liquid Jet Compressor with Nitrogen Lifting Through Coiled Tubing for Logging a Low Pressure Horizontal Well

Published: March 2017

Abstract
A coiled tubing (CT) campaign was executed on the Skjold field in the Danish sector of the North Sea in 2014. One of the objectives of this campaign was to perform production logging in horizontal oil producer wells, located in a highly fractured chalk reservoir. Most of these wells are unable to flow without artificial lift due to the high water cut and low reservoir pressure. Stable flow for logging was achieved by combining CT operations with a surface Liquid Jet Compressor (LJC). The campaign was successful in acquiring both production (PLT) and spectral noise logging (SNL) data.
The SNL tool complemented conventional PLT as it provided information on quality of zonal isolation, vital in planning of water shut off and/or re-stimulation activities.
Well A was completed with a gas lift valve straddle which had to be retrieved to gain access to the wellbore for production logging. Retrieving the straddle disabled access to lift gas, which meant the well was unable to produce. Liquid jet compressor technology in combination with nitrogen lifting through CT was implemented to allow steady fluid flow for logging.
The surface liquid jet compressor (LJC) lowered the production system backpressure seen by the well from 500 psig to 0. Together with the continuous nitrogen pumping through CT, stable well flow was achieved and the logging program was successfully executed. The results were used to identify fluid flow behind casing, water producing zones and to identify sub-optimally producing oil zones for re-stimulation. Using the LJC significantly reduced the total nitrogen volume required by 60%. This was crucial as limited crane capacity and deck space presented additional logistical and operational challenges. In order to overcome these, equipment had to be rigged up on a bridge connecting two platforms with the CT reel lifted in three spools and welded on location. This in turn required the fiber optic cable to be injected on-site offshore.
The novel combination of a surface LJC with nitrogen lifting via CT reduced the number of crane lifts, load outs, nitrogen transfers and overall cost. Furthermore, it improved operational efficiency and job safety.
Ultimately, this combined concept enabled successful acquisition of the required data.

Abstract
This work is focused on exploring the applicability of intelligent methods in assessing porosity and permeability in the context of reservoir characterization. The main motivation underlying our study is that appropriate estimation of reservoir petrophysical parameters such as porosity and/or permeability is a key step for in-situ hydrocarbon reservoir evaluation. We ground our analysis on information on log-depth, caliper, conductivity, sonic logging, natural gamma, density and neutron porosity, water saturation, percentage of shale volume, and type of lithology collected from well loggings in an oil field in the middle-east (a total number of 11 exploratory wells are considered). Data also include porosities and permeabilities evaluated on core samples from the same wells. All these data are embedded in a neural network-based approach which enables us to establish input-output relationships in terms of an optimized number of input variables. Three diverse intelligent techniques are tested. These include: (i) classical artificial neural networks; (ii) artificial neural networks based on principal component analysis (PCA) transformation; and (iii) statistical neural networks based on a bagging approach. Our results suggest that the statistical neural network is most effective for the field setting considered. The application of this neural network with 9 input parameters provides reliable performances in 94% and 81% of the cases, respectively in the training and validation phases, for the estimation of porosity. A trained network with 10 input parameters leads to successfull reproduction of permeability values in 85% and 79.5% of the cases, respectively during training and validation of the network. Results from this study are expected to be transferable to applications involving evaluation of petrophysical properties of a target reservoir in the presence of incomplete well log datasets.

Published: March 2017

This paper presents a fast DCT algorithm by using convolution method. Multipliers will be a crucial process in designing a fast DCT algorithm because they take a long time to complete their process. Reducing a number of multipliers is the one way to make a fast DCT algorithm. This paper shows how to reduce multipliers by using two steps: the first step is by grouping transformation matrix to be two groups in which this process uses the folding concept. The second step is by using fast convolution by inspection to minimize multipliers. Keywords : multiplier, fast DCT, fast convolution, folding.

The Protection of Indonesian Indigenous Heritage in the International Conventions and Their Implication toward Indonesian Law
Authors: Maruf Irma Rachmawati 
Published: March 2017

As an archipelago, Indonesia consists of 17.507 islands. The regions of Indonesia have some of their indigenous ethnic groups. However, in the light of the geographical aspect, Indonesia has 128 ethnics groups which have different cultures. Meanwhile, since the end of 1990s, the topic of genetic resources, traditional knowledge and Indigenous heritage ambit of Intellectual property discussions. Batik and Angklung are Indonesian Indigenous heritage which have been acknowledged by UNESCO as Intangible Cultural Heritage. One of the purposes of the acknowledgment is to avoid any claim from another country which has the same culture. Besides batik and angklung, there are so many indigenous heritages that have not been acknowledged as Intangible Cultural Heritage. Due to this condition, the research is made to know what the protection should be given by law to Indigenous heritage in international law perspective. There is also how the implementation of International convention to Indonesian law can protect and maintain the cultural heritage.The method used in this study is a juridical normative with the specifications of analytical description. The research was conducted by collecting primary, secondary and tertiary legal materials through library and field research, and then analyzed with qualitative method.Based on the results of this study, it is revealed that: Firstly, the legal basis of the application of the Implementation of Protection of Indonesian Indigenous heritage have been already very relevant but still insufficient in implementation. Hence, it is not impossible that Indonesian government can take economic advantages of Indigenous Heritage. Secondly, there are various forms of Legal protection of Indigenous Heritage, these are Law of Intellectual Property Right and Legal Protection besides Intellectual Property.Keyword : Indigenous Heritage, Intangible Cultural Heritage, Intelectual Property Right Law.
Media And Cultural Heritage
Authors: Hutagalung Inge 
Published: March 2017

In general, media coverage can have a strong influence on the reputation of a cultural heritage. Media coverage often has an effect on a cultural heritage’s reputation when ‘good’ or ‘bad’ news is reported.This amplifying effect has often been studied through the lens of agenda setting theory. The hypothesis behind the theory is that the frequency with the media report on an issue determines that issues’ salience in the minds of the general public. In other words, the media may not be successful often time in telling people what to think, but it is stunningly successful in telling its readers what to think about. The news media ‘set’ the public agenda.Since people cannot possibly attend no to every little detail about the cultural heritage around them, setting in communication is important because it helps shape the perspectives through which people see all cultural heritage in the world.In generating good news coverage about a cultural heritage, communicating with the media is one of important activities that should be maintained between communication professionals (in cultural heritage) with journalists. Keywords: media coverage, agenda setting, framing news
Indigenous Garments and Accessories of the G’addang in Barangay Ngileb: Documentation on Production
Authors: Garra Angela 
Published: March 2017

This study was undertaken to document the production of indigenous garments and accessories of the Gaddang in Barangay Ngileb in Alfonso Lista, Ifugao to help preserve the culture in making such products. Using qualitative research, it explored the different product-making procedures by using the method of focus group discussion (FGD) or interview with photo-video documentation and actual observation to analyze information from five female respondents. With the results of the study, the following were gathered: main processes involved are weaving, cutting, sewing and bead designing. Tools they use are traditional and it is operated manually. It depends on what product and availability of the raw materials on how long it takes to finish. Gaddangs produce other products like cellphone cases, pen holder and bags. With the use of other resources like carabao horns, wild pig fangs, chicken feathers and kugon grass are also utilized, but other resources like fabric, beads and cotton threads are bought outside their community. They still have their beliefs, and colors they use are dominantly red inorder for them to be distinguished among others. They use quality threads inorder to maintain the best quality they have. And with just a little profit they gain, it is use to supplement their needs like foods, and other school finances for their children. And preserving this culture through this way, it will be of great benefit for the Gaddangs.
