Increasing Production by Diagnosing Well Productivity: A Case Study for Other Mature Fields
Authors: Peretti Francis , Montilva Antonio , Rodriguez Lenin , Rosario Omar , Torrealba Julio , Martinez Mauro
Published: March 2017

The workflow for mature-field redevelopment requires a multidisciplinary team to analyze, select, and rank well candidates for intervention and production optimization. An objective evaluation of the well's productivity and reserves is essential for identifying possible alternatives to increase production. For this study, an analysis was conducted on 152 wells from the Carito field. As the second-largest oilfield producer in the Maturin sub-basin of eastern Venezuela, the Carito field encompasses approximately 150 km2 and comprises the El Carito and Carito south reservoirs.

The Carito reservoir presents a high degree of heterogeneity resulting from complex, compressional faulting and varying sediments and includes hydrocarbons containing gas, condensate, volatile, black oils, and tar mat (oil mixed with wet sand). The Carito south reservoir behaves like a black-oil reservoir. The workflow presented in this study identified 20 candidate wells ranked by their potential to increase production. An intervention plan was then defined and ranked according to technical and economic criteria. This paper presents the successful application of this methodology in the Carito field to improve well productivity by approximately 7,000 bpd, proving that the method can be easily adapted to other areas.

Published: March 2017

Started in the late 1800s in the US, water being relatively inexpensive, readily available in large volumes and also being very effective at significantly increasing oil recovery, waterflooding has been the most common secondary recovery method applied throughout the world, contributing to pressure maintenance in the reservoir and displacing the oil phase. While there are several parameters that influence the performance of a waterflood, water quality is one of the most important factors as it may cause scaling in injection wells as well as some formation damage through chemical phenomena such as, cation exchange in the reservoir, resulting in decreased the recoveries.

As waterfloods continue over decades, prevention of scale formation becomes a more significant factor that needs to be properly treated. Precipitation of inorganic scale is a major issue in injecting brines with a high concentration of divalent ions. Scaling tendency of water is highly correlated with the hardness of injection water.

Following corrosion, insoluble iron precipitates can cause damage in injection wells since precipitates can lead to severe reductions in well injectivity. Water needs to be treated in a proper way, if the water contains high concentrations of calcium, magnesium or iron. In most waterflood applications, seawater needs to be used and this phenomenon is also an issue when injecting seawater into formations that contain brines with high salinity.

In this study, we provide a comprehensive analysis of this common problem by investigating the significance of parameters affecting the severity of scale formation through utilizing a seawater scale buildup model that will be simulated using a commercial simulator along with an in-depth review of previous studies.
Case Study: Pressure-Transient Analysis Behind Oil Production Hike in a Mature Onshore Field in the Brazilian Northeast
Authors: Kubota L.. , Souto F..
Published: March 2017

This paper reports on the successful application of Pressure Transient Analysis (PTA) providing theoretical background to support the hydraulic fracturing of several reservoirs in the Brazilian Northeast, thus leading to a huge hike in oil production.

We describe how PTA has helped shed light on the fact such reservoir should not be viewed as a conventional system, but rather as an unconventional one. Based on our findings, we conjecture that it could be regarded as a fracture network surrounded by a porous matrix.

That being said, a hydraulic fracture would readily connect the wellbore with the fracture network, bypassing the less permeable matrix, and, as a result, cause an increase in oil production. The gain in oil flow rate, in our examples, has averaged a tenfold increase. Not only did PTA help increase oil production, it also helped shed light on how best to read the dynamic behavior of a mature reservoir.
A Challenging Workover in an Offshore Fixed Platform - Accessing Bypassed Hydrocarbons
Authors: Fernandes F. F. , Nakajima L.. , Rodrigues V. F.
Published: March 2017

This paper presents the planning, execution, and lessons learned of a challenging workover focused on accessing bypassed hydrocarbons for production increase. The workover goal was to add two-bypassed zones, a high quality upper carbonate zone and a thin bed of sandstone, both above the production casing shoe, to the openhole carbonate production of a horizontal well in a fixed offshore platform. Polvo is a brown or mature field in shallow waters of Campos Basin, Brazil. Among the typical problems of mature fields, Polvo shows only pressure drop, declining oil rate, and high water influx, with 80% average water cut. To extend the economic life of Polvo, a huge challenge in the current downturn, its independent operator is rejuvenating existing producing wells, optimizing flow, and identifying, quantifying and accessing bypassed hydrocarbons. The original well was completed in a lower carbonate zone in a 604 m openhole lateral section with sand control screens. After reviewing reservoir and well data, the operator team found the two mentioned bypassed zones. In order to access these zones, it was necessary to perforate them, to control sand production in the sandstone, and to deploy an intermediate completion. Because of internal diameter restriction in the lower completion, hydrajetting replaced casing gun operations in both zones. Sand control in the high angle sandstone interval was a challenge. A specific fracturing/gravel operation followed, successfully, a failed sandstone consolidation trial. Among the main challenges this workover faced budget and time limitations, once the rig operated on a temporary contract, and material, equipment, and footprint restrictions, not mentioning lack of relevant information about the bypassed sandstone zone.
Determining the Sweep Efficiency of Waterflooding Using Tracers
Authors: Melo M. A. , Almeida A. R.
Published: March 2017

Water injection is extensively applied as an oil recovery method. This generates a large volume of produced water that must be separated from the production stream and disposed with technical, economic and environmental consequences. The optimized use of water resources in the oil production is linked with the sweep efficiency or drainage of that water in the reservoir, which is the aim of this article. The inaccessibility of petroleum reservoirs associated with the lack of tools able to effectively characterize the rock formation channels make tracers a very important qualitative and quantitative evaluation technique to date and indispensable to the management of such water. The hydrodynamic characterization of channels traversed is possible by previously marking the fluid with a water-soluble conservative tracer, which, by definition, flows through the formation dissolved in water without interacting with the rock-fluid system, i.e., without chemical reaction or adsorption (conservative or ideal tracer). This work builds a connection between laboratory experiments and field data. Laboratory tests were performed in a linear (1-D) physical model (with target-field rock) and in a 5-spot physical model (outcrop rock), using the target field water and with temperature of the target field (1-D test) or room temperature (2-D test). The field application was performed in a reduced pilot consisting of an inverted 5-spot unit (1 injection well and 4 production wells). The mathematical simulation of 1-D laboratory data was made using the traditional convection-diffusion equation. Field and laboratory 5-spot data were adjusted using a mathematical model (2-D convection-diffusion equation) and its analytical solution through the Generalized Integral Transform Technique (GITT) for an ideal 5-spot pattern. This study suggests that working with a tracer pulse, instead of a slug, is the best strategy and facilitates the interpretation of lab and/or field results. Furthermore, it is possible to estimate the sweep efficiency using the mathematical interpretation of a pulse. The collected information allows the interpretation of the hydrodynamic characteristics of the studied field area and serves as a basis for future EOR applications of polymers and/or surfactants.

La familia como mediadora ante la brecha digital: repercusión en la autoridad
Authors: López-Sánchez Carmen , García del Castillo Rodríguez José A.
Published: March 2017

En la era digital es imprescindible replantearse el papel educativo de la familia. Las nuevas tecnologías de la información y la comunicación han convulsionado las relaciones interpersonales y familiares. En este ensayo se analizan tres componentes fundamentales en referencia a la educación digital de los menores: la familia como mediadora del proceso educativo de los hijos; la brecha digital como disponibilidad de contar con la capacidad y habilidad suficientes para utilizar los servicios digitales y la autoridad como la tutorización de los menores basada en la capacidad competente adquirida por los adultos de referencia, normalmente los padres, a lo largo de su vida, que los faculta para ejercer su autoridad en todos los ámbitos, desde el moral hasta el de conocimientos. Se llega a la conclusión de que la familia tiene que afrontar una doble visión de las tecnologías de la información y la comunicación que compromete muchos de los valores básicos de su función formadora con los hijos. Esta doble visión viene representada por el polo positivo: el avance, la facilitación de tareas, el desarrollo de sistemas más eficientes, y por el polo negativo: la involución, la facilitación de nuevos riesgos, mayor vulnerabilidad personal y social. El éxito pasa por llevar a cabo una mediación familiar óptima, romper las trabas que produce la brecha digital y confluir ambas cuestiones en la promoción de unas competencias mínimas por parte de los padres para ejercer adecuadamente la autoridad. © Revista Colombiana de Ciencias Sociales.

Regulatory Role of G Protein-coupled Receptors in Pancreatic Cancer Development and Progression
Authors: Schuller Hildegard M.
Published: March 2017

Background:

Pancreatic cancer is the fourth leading cause of cancer deaths with
rising incidence and a high mortality rate. Smoking, psychological stress, diabetes, pancreatitis
and alcohol abuse are known risk factors for pancreatic cancer.

Objective:

Targeting G protein-coupled receptor signaling for the prevention and therapy of
pancreatic cancer.

Method:

Review of published literature.

Results and Conclusion:

All known risk factors for pancreatic cancer cause hyperactive
cyclic adenosine monophosphate (cAMP) signaling via cancer stimulating Gαs-coupled
beta-adrenergic and prostaglandin E2 receptors and/or by suppressing signaling via inhibitory
Gαi-coupled GABAB-receptors. Psychological stress in mice promotes the progression
of pancreatic cancer xenografts via stress neurotransmitter-mediated increase in betaadrenergic
signaling and suppression of GABA while stress reduction inhibits pancreatic
cancer by reversing these effects. The activation of Gαi-coupled GABAB-receptor signaling
by treatment with GABA, inhibition of beta-adrenergic signaling by a beta-blocker and/or
suppression of Gαs-coupled PGE2 receptor signaling by a cyclooxygenase (COX) inhibitor
prevent the development and progression of pancreatic cancer induced in hamsters by carcinogenic
nitrosamines and in transgenic mice. The re-purposing of cardiovascular therapeutics
(beta-blockers, COX-2 inhibitors, Ca2+-channel blockers) that inhibit betaadrenergic
and PGE2 signaling for pancreatic cancer intervention is problematic due to undesirable
side effects under chronic treatment protocols. To avoid such side effects while
effectively reducing excessive cAMP signaling, nutritional GABA supplementation or
positive allosteric modulators (PAMs) of Gαi-coupled receptors (GABAB-Rs) currently in
clinical trials for the treatment of addiction should be explored for pancreatic cancer intervention.

Authors: Yasa I Wayan Suka
Published: March 2017

Ongkara Pranawa is the core symbol to which the belief system of the Balinese Hindus is concentrated. This article is focused on understanding the Ongkara Pranawa in the Balinese alphabetic system. The perspective to read and understand this phenomenon is the Saivistic-pantheism by utilizing the Hindu theory and method of interpretation called smreti and tri pramana. Through the analysis it is found that the Ongkara Pranawa is the revelation of God in the form of Balinese letter. God is understood to have the character of Eka-Aneka; He is one and plural at the same time. Willfully God takes His functional role in various figures and names. This understanding provides tolerant viewpoint in responding the variety of human religiosity.
The Affix me-/-kan and me(n)-/-kan in the Presidential Candidates’ debate texts in 2014 – 2019: Morphology Observation on Derivation and Inflection
Authors: Intiana Siti Rohana Hariana , Sapiin -
Published: March 2017

The affix me-/-kan, me (N)- and -kan have a tendency to form classes of verbs. The process of forming verbs can be constructed from nouns, adjectives, and adverbs. Moreover, there are also verbs which do not change the class, although it has experienced the process of affixation. These phenomena are known as derivation and inflection. Derivation system and status change of these verbs applied to the debate text of RI presidential candidates in the period of 2014 to 2015. The study aims to describe the derivation and inflection system in the candidates’ debate texts. The concept of derivation and inflection is formed based on several criteria, such as class or status and acceptance in the clause. The data analysis only focuses on the candidates’ debate texts. The data were collected by writing the text documents for patterning and sorting. The result of the research on the candidates’ debate texts is that a derivation process occurs in class N → V, A → V, and Adv → V. Moreover, inflection does not change the class of verb, such as V → V. However, in a different view, the change of V → V can be considered as derivation, on the basis that it can change the semantics and clause. Therefore, it is hoped this research can describe the construction of derivation and inflection.

A Review on the Components of EEG-based Motor Imagery Classification with Quantitative Comparison
Authors: Rahman M. K.M , Joadder Md. A. Mannan
Published: March 2017

Motor Imagery (MI) is a voluntary modulation of brain signals for specific action without real limb movement. It is essential to classify MI signal to design a brain computer interface (BCI). BCI involves a number of signal processing steps, and a lot of techniques have been developed for each step. There can be numerous combinations of these techniques at different steps that can be employed to design a BCI. This work focuses on MI-based BCI using EEG signal and reviews the existing techniques. More importantly, a detailed comparative study is performed to explore the important combinations of methods by comparing their performance quantitatively. Often a method, which performs very good in one combination, can be bad performer in other combinations and it is a dilemma for the researchers to select appropriate methods for their desired BCI application.In our performance analysis, we have systematically included the variations of methods in each step of BCI such that it gives idea to BCI researchers how each method in one step fits best with specific combinations of methods in other steps. We have shown that how much each step is sensitive towards overall performance of the BCI system.We hope that this work helps, especially for new researchers, to provide a better guideline for designing more efficient BCI system.
Programming without Programming Languages (New Graphic Poliglot Сoncept)
Authors: Velbitsky Igor
Published: March 2017

For the first time since 1947 it is proposed to use a simpler and mathematically more rigorous concept of programming with the graphs loaded only through horizontal arcs with characters, functions and expressions of elementary mathematics. Such graph is a polyglot, it has ISO 8631/1989 standard, and is the only one that can be used effectively throughout the life cycle of program design and use. Conventional programming languages are not needed. The new concept has 100+ times better characteristics with regard to visualization, simplicity, and compactness, as well as the speed of entering into the computer. Processes of error-free design of algorithms, programs, and data structures, evidence of their correctness, self-documenting and documenting of motivation of decisions made are significantly simplified, improved and accelerated. The resulting programs are more effective on the memory footprint and execution time. The larger and the more complex is the program project, the greater is the effect of applying the new concept. The new concept is so simple that it makes it possible to program for ANYONE, not just for programmers. We do not know analogue of the new concept. This article describes the history of developing and proving the new concept, its description, advantages, implemented graphical programming environment, and perspectives for its application.

This research aims to develop biopesticides for pests and plant diseases. It was conducted at the PEM laboratory UIN Suska Riau and on land, from July to November 2015. The sourches were extracts from Andropogon nardus, Annona muricata leaves, Ageratum conyzoides, Piper aduncun fructus, Nicotiana tabacum leaves, Tinospora crispa, Azadirachta indica leaves, Allium sativum and Piper betle leaves. Each the source was macerated in alcohol 50% for 24 hours and then distilled at a temperature of 60 °C until all the alcohol evaporates. The experimental Design was complete random design with 7 treatments (control, 20%, 40%, 60%, 80%, 100% and chemical pesticides as positif control) and 3 replicates. Parameters of the test biopesticides to disease performed in vitro with measure the resistance zones and for mealybugs and Gryllus assimilis in vivo with the pest mortality. Biopesticide test in vitro for the bacteria that causes carrot root rot has not been able to kill microbes. The mortality rate mealybugs begins before 1 hour observation at the treatment biopesticide concentration of 80%, 100% and control positif.  Provision of different concentrations of biopesticides, does not the increased mortality of Gryllus assimilis. This shows that the power to kill biopesticide still well below chemical pesticides, but the pest is still alive no appetite as antifeedant effect of the biopesticide. So biopesticide application does not have to kill the target pest. Need  follow-up and development of this research and other pests.
