Portfolio investment as a factor for the development of the Russian economy as one of the BRIC countries
Authors: Broszkiewicz Magdalena
Published: November 2017

Portfolio investments have an impact on the development of financial markets around the world, especially in countries of growing importance for the global economy. Russia is one of the countries which are mainly linked to the energy and raw materials sector, so at a time of fluctuations on those markets, its economy is less predictible for international investors. The regulations for investors in this country (also non-residents) need to be improved to overcome the negative effects of world financial crisises and to rebuild financial markets. Russia is also an economy with large amounts of capital to invest, so it is interesting to observe its financial flows to other countries in the situation when existing regulations are stopping capital for domestic investment. The following article analyzes the flows of portfolio investment in Russia in the twenty-first century based on balance of payments data in conjunction with changes in the geopolitical situation and the investment attractiveness of the country. Capital invested in the form of portfolio investments is fragile and often short-term, and it is most vulnerable to periods of recession, causing rapid changes in the flow of this kind of capital. These relationships can be clearly observed in Russia. The strong interest of foreign investors in the Russian economy, in the form of direct and portfolio investments, started in 2000 and lasted until 2006. In the first half of 2008, decreases were slow compared to the record high of the previous year, but from September they accelerated to such an extent that by the end of the year they had reached almost 100%, depicting a sharp decline of foreign investors’ interest in the Russian securities market. This translated into a decline on the Russian stock market. The Russian economy since the beginning of the twenty-first century has experienced a significant influx of foreign capital, including in the form of portfolio investment. However, in comparison with the possibilities of the development of the economic potential of Russia, it is still a small amount.

I Won’t Do EMDR! The Use of the “Sleeping Dogs” Method to Overcome Children’s Resistance to EMDR Therapy
Authors: Struik Arianne , Ensink Judith B. M. , Lindauer Ramón J. L.
Published: November 2017

This article provides a comprehensive review of the challenges faced by chronically abused children and their treatment providers. The main aim of this pilot study was to explore whether chronically traumatized children, who presented as unable or unwilling to engage in eye movement desensitization and reprocessing (EMDR) therapy, could be prepared with the “Sleeping Dogs” method to complete EMDR therapy. The second aim was to determine whether there was sufficient reduction in posttraumatic stress symptoms to enable positive placement decisions. Participants were 14 children, age 3–9 years (M= 5.1), refusing to participate in EMDR therapy. All were living in residential care (n= 12) or with foster families (n= 2) and were considered stuck cases because of their severe problems. With the treatment package of “Sleeping Dogs” plus EMDR therapy, all children completed EMDR therapy in an average of 7.57 sessions leading to the resolution of all identified traumatic memories. At posttest, the Trauma Symptom Checklist for Young Children showed a significant reduction of scores on the Intrusion and Depression subscales. Two thirds of the children (n= 8) who were in residential care at study onset were placed in foster families within 2 months after the last session, some even during treatment. This is the first study on the “Sleeping Dogs” method and even though the limited sample size and research design restricts generalization of results, the present findings suggest important directions for future study.
Use of the Flash Technique in EMDR Therapy: Four Case Examples
Authors: Manfield Philip , Lovett Joan , Engel Lewis , Manfield David
Published: November 2017

This article introduces the flash technique, a new technique used during the preparation phase of eye movement desensitization and reprocessing (EMDR) therapy to facilitate processing of intense, traumatic memories that clients might otherwise be resistant to access. Anecdotal evidence suggests that this technique may make it possible for clients to access these memories initially in a minimally disturbing way, reducing their emotional intensity so that they can then be more easily and fully processed using EMDR therapy. The technique appears to be easily tolerated by clients of all ages, including children; and to be rapid and relatively painless for clients, even those with particularly disturbing target memories; and can be easily taught to clinicians. It has the distinct feature that clients who are avoiding a terribly disturbing memory can be offered a way of processing it without having to bring it clearly to mind. Four case examples, in which the technique was used by four different clinicians, are presented briefly. Suggestions are made for further study. This article hypothesizes various mechanisms of action and discusses the effects in terms of memory reconsolidation theory.
EMDR, Community Psychology, and Innovative Applications of a Trauma Recovery Network as a Tool for Social Change
Authors: Rosenblum Rebecca E. , Dockstader David J. , Martin S. Atyia
Published: November 2017

This article discusses the need for and ways to implement novel applications of early eye movement desensitization and reprocessing (EMDR) interventions (EEIs) at the community level for marginalized groups. Trauma Recovery Networks (locally based groups of licensed EMDR clinicians volunteering to provide pro bono disaster services, also known as TRNs) are an underused and insufficiently tapped tool when it comes to addressing the sequelae of disasters in our communities. We propose expanding our concept of and work with disasters beyond the traditional, legally recognized definition of Disaster (big D) to include ongoing stressful and traumatic community events or “little d” disasters. By serving those affected by little d disasters, the field of disaster response can be broadened in powerful ways. Marginalized communities typically suffer more and receive fewer services in the wake of traditional Disasters, threatening their civil rights and increasing the allostatic load on their collective health. Attending to the ongoing little d disasters, in these communities can be an important tool for social change, and various proposals for local TRNs are discussed.

Accurate and timely rainfall prediction enhances productivity and can aid proper planning in sectors such as agriculture, health, transport and water resources. This study is aimed at improving rainfall prediction using ensemble methods. It first assesses the performance of six convective schemes (Kain–Fritsch (KF); Betts–Miller–Janji´c (BMJ); Grell–Fretas (GF); Grell 3D ensemble (G3); New–Tiedke (NT) and Grell–Devenyi (GD)) using the root mean square error (RMSE) and mean error (ME) focusing on the March–May 2013 rainfall period over Uganda. 18 ensemble members are generated from the three best performing convective schemes (i.e. KF, GF & G3). The performance of three ensemble methods (i.e. ensemble mean (EM); ensemble mean analogue (EMA) and multi–member analogue ensemble (MAEM)) is also analyzed using the RMSE and ME. The EM presented a smaller RMSE compared to individual schemes (EM:10.02; KF:23.96; BMJ:26.04; GF:25.85; G3:24.07; NT:29.13 & GD:26.27) and a better bias (EM:-1.28; KF:-1.62; BMJ:-4.04; GF:-3.90; G3:-3.62; NT:-5.41 & GD:-4.07). The EMA and MAEM presented 13 out of 21 stations & 17 out of 21 stations respectively with smaller RMSE compared to EM thus demonstrating additional improvement in predictive performance. The MAEM is a new approach proposed and described in the study.

An Innovative Approach for Stimulation Treatment in Clastic Reservoir Quadruples Net Oil Production
Authors: Hassan M. Hafiidz , Rusman Liyana , Chandrakant Ashvin A. , Haslan M. Hanif , Moktar Nur Syazwani , Abdussalam Khomeini
Published: November 2017

Matrix acidizing is an attractive treatment choice in clastic reservoirs to remove near-wellbore damage due to its relatively low cost. It has been executed countless times in brownfields East Malaysia with a moderate to high success rate to arrest production decline due to fines migration and scale deposition. Nonetheless, there is a critical need to look back on the choice of treatment chemicals and treatment approach in order to ensure optimum chemical volume, attractive production gain and higher success rate, especially in the current low oil price era. This paper will focus on the planning and successful execution of single-stage acid (SSA) combined with wax solvent stimulation treatments resulting in fourfold increase in net oil production post treatment in two wells in Field X offshore East Malaysia.

Well A18 and C33 experienced production impairment due to formation damage fines and organic scale. Combination of both wax solvent and SSA in the same treatment was used to remove the damage. Application of SSA eliminates the need for hydrochloric acid (HCl) pre and post flush thus reduces treatment volume, simplifies treatment execution and consequently reduces overall treatment time. Additionally, the usage of retarders eliminates fast reaction of hydrofluoric acid (HF) thereby allowing for deeper HF penetration. This paper also discusses the rapid decline observed post treatment for Well A18 is mainly contributed by re-mobilization of fines due to higher flow rates and re-buildup of wax within tubing and near wellbore. Proactive measures such as pressure drawdown management are suggested to prevent reoccurrence in future stimulation treatments.

In conclusion, this paper finds that the combination of wax solvent and SSA was successful in both removing the damage and optimizing treatment schedule. Correct identification of damage source coupled with good treatment design was able to quadruple production from well A18 and C33 in Field X.

This paper presents an innovative approach and cost effective solution in successfully mitigating formation damage caused by a combination of fines migration and organic scale. This single-stage stimulation treatment saves time, treatment volume and reduces job complexity.
Trials of CT Operations in Ultra-Deep HTHP Wells in Tarim Basin, Western China
Authors: Huifeng Liu , Xiangtong Yang , Wei Zhang , Yan Zhang , Pengyao Zhou , Xi Wang
Published: November 2017

Wells in kuqa foreland area of Tarim Basin are mostly ultra-deep and HTHP wells. The well depths vary from 6000 m to 8000 m. The reservoir temperature and pressure are between 135-180℃, 100-135MPa respectively. Coiled tubing was introduced to conduct the down-hole operations in this field. Through improvements of many technologies, six operations were successfully conducted and operating time was saved by more than 50%.

CT operations in HTHP wells were made available by carefully evaluating and selecting the proper CT assembly and operating parameters. A standardized modeling workflow was established, including force analysis, hydraulic analysis and fatigue analysis, to systematically evaluate the operation, and then optimize the CT assembly, the wellhead equipment, the operating parameters, etc. A real-time CT detector was also developed to monitor the properties of CT while operating. Besides, a series of on-site operation criteria were established to control the process of CT operations.

With these modeling, optimizing and monitoring technologies, CT operations were firstly tried in ultra-deep wells in the basin area of Tarim Basin, whose well depths are more than 6000m but with normal pressure and temperature systems. Drilling and milling, acidizing, jet perforating, and staged proppant fracturing were all realized in these wells. Well YM704, with down-hole pressure of 82MPa and down-hole temperature of 148℃, was acid pickled with CT at vertical depth of 7287m. Afterwards these technologies were introduced to kuqa foreland area, where the wells are mostly HTHP gas wells. Six down-hole operations have been tried and only minor troubles occurred. Well KS2-2-12, whose down-hole pressure is 102MPa and down-hole temperature is 160℃, was sand flushed by CT at the depth of 6182m, and a 46m sand plug in the wellbore was cleaned out. Well DB101-1, with down-hole pressure of 92MPa and down-hole temperature of 130℃, was conducted workover by CT. CT was run to 5373m and successfully drilled and milled the bridge plug. By using CT operations in these wells, more than 50% of the operation time was saved.

CT has been proved to be an efficient tool for down-hole operations. It can reduce the cost of operations significantly. However, the use of it was restricted to conventional wells. This paper introduces trials of CT operations in ultra-deep and HTHP wells, providing a reference for CT operation design in tough conditions. Resistance of running in hole was also encountered occasionally, but it is hopefully to be avoided by optimizing run-in modeling.
Value of Portable High Frequency Multiphase Flow Meter Testing for Brownfield Well Production Optimisation and Maximising Reservoir Performance - A Case Study of An Offshore Brownfield in Peninsular Malaysia

Published: November 2017

This case study highlights the difficulties and challenges faced by a mature brownfield (40+ year field life and 330+ wells) producing via multiple offshore satellite platforms. Daily production issues include sub-optimal well-testing facilities, uncertainties in well performance, sand production, well flow assurance, gas-lift compressors uptime, bottlenecked pipelines and integrity problems. This paper showcases the journey of an operator in using portable high frequency MPFM well-test unit for closing the well-test data gap in offshore brownfields of Peninsular Malaysia. Here, the paper shares the lessons learnt and workflow for effective well-test data gathering and validation, diagnosing well performance using dynamic well behaviour recorded by high frequency MPFM, and subsequent well optimisation activities (such as choke optimisation, gas-lift optimisation and flowline de-bottlenecking) for rapidly improving well production. Moreover, this paper also highlights key findings such as related to PVT data input and how it can affect MPFM measurement accuracy. Ultimately, the use of portable high frequency MPFM has helped field operation to maximise oil production and arresting field production decline.
The 7 Sins of Managing Acoustic Sand Monitoring Systems
Authors: Lee P. Y , Kasper S. Frederiksen , Quinn Christer
Published: November 2017

It is a common misconception, upon installation of an acoustic sand monitoring system, that the acoustic systems should provide an accurate measurement of sand volumes and that all sand detection issues are immediately solved. The truth is there is more to that than just installing a piece of equipment and hoping that it would provide us a crystal ball insight to the sand produced. Therefore, the aim of this paper is to share the top 7 learnings our asset has experienced on managing acoustic sand monitoring systems.

The 7 Sins that would be discussed are:

Knowing if it is sand and underestimating external noise Lack of continuous calibration of the acoustic systems Trusting solely the calculated sand volumes Lack of data correlation with other available field data Understanding trends from acoustic systems does not happen overnight, practice makes perfect Not acknowledging undetected sand (fines) Not realising that acoustic systems are just a small part of the bigger sand management picture

In each learning, field example cases will be presented where both positive and negative results will be described and discussed. This paper will touch upon the agreed sand management philosophy and procedures and how it has worked out for us so far. The philosophy we have adapted into the asset considers the field as a matured asset, showcasing a multidisciplinary approach.

This paper will be concluded with future work moving forward on how we can perform better with our existing knowledge on the acoustic sand monitoring systems.
Applying the Integrated 3D Acid Fracturing Model Using a New Workflow in a Field Case Study
Authors: Jin X.. , Zhang Hui , Yin Guoqing , Han Xingjie , Zhu D..
Published: November 2017

Acid fracturing stimulation involves several major steps; a hydraulically induced fracture is created by pad fluids first, then reactive fluids are injected into the fracture, often alternating with a viscous pad to create etched fracture length. When pumping stops, the fracture closes up, and conductivity is created by an uneven fracture surface. An integrated modeling approach is introduced to simulate acid fracturing processes and diagnose operation problems. The integrated design/diagnose approach includes a fracture propagation model for fracture geometry, an acid transport model and a well performance model. The fracture geometry model is coupled with a 3D acid fracturing model to simulate acid transport and the resultant fracture conductivity. The fracture conductivity is then utilized in the well performance model to predict the well productivityafter treatment. This simulated well performance can be used to match the production data to verify the models. In this field case study, we did not have the information about formation leakoff to start the fracture geometry model. To successfully analyze the well treatment, a three step inversion workflow was proposed. The inversion workflow started from estimating a skin factor after stimulation by matching the production data. This skin factor was then converted to a fracture length that resulted in the production history. A pseudo 3D fracture model was used to predict fracture geometry. With the fixed length as a constraint, we varied the leakoff coefficient until we obtained the correct geometry. The simulated fracture geometry from the fracture propagation model was used as an input in the 3D acid fracturing model to simulate the fracture conductivity profile. The conductivity was confirmed with the fracture conductivity from lab experimental test result. To close the analysis loop, the conductivity should also be consistent with the one used in production history matching.

Fracture geometry was generated by the commercial software, MFrac, and acid fracturing was simulated by a 3D model developed before. Two wells are selected for the field case study to illustrate the application of the approach, with one well has improved productivity after acid fracturing, and the other has no response after acid fracturing. By applying the inversed integrated 3D acid fracturing modeling workflow, it showed that the well with high productivity had a fracture conductivity resembling the conductivity values fromthe experimental lab measurements. The well with low productivity showed poor fracture length and width, leading to a low production.

This paper will demonstrate how the acid fracturing stimulation using different technologies in multidisciplinary team integration helped un-locking the production potential and setting up development strategy for Tuba tight carbonate reservoir, with case histories.

Upcoming Reservoirs in North Kuwait (NK) oil fields will play significant role for meeting NK's strategic production target. Recent full field study of Tuba carbonate reservoir makes it the largest Oil in-Place of the Upcoming Reservoirs in NK.

Tuba, though discovered in the 60's, is still relatively under-exploited presently with only 12 active wells with very low total production rate compared to other reservoirs. High reservoir heterogeneity, tightness and poor fluid properties necessitate the move from conventional matrix stimulation to Acid Fracturing technology targeting better Frack conductivity and deep penetration for effective productivity and recovery enhancement. With efforts of multidisciplinary team, Acid Frac fluid, diverter and high leak off control technologies have been designed and executed successfully in 9 wells (7 vertical and 2 multistage horizontal) covering multiple reservoir layers with very positive results that proved the concept and supported more TUBA development.

Many technical and operational challenges were faced and properly handled with lessons learned are to be considered in next designs and executions.

Despite the close results yielded from the multistage acid fracturing in two horizontal wells compared to the results from 7 vertical wells, it is still early to evaluate stimulation potential of horizontal against vertical wells. It needs more production history and more wells to evaluate long term sustainability.

The results of such evaluation will formulate the drilling, completion and stimulation development strategy for the entire TUBA reservoir including early fracturing stimulation to improve initial productivity that will contribute significantly to the NK production target.
Near Wellbore Characterization from Temperature Transient Analysis: Accounting for Non-Darcy Flow Effect
Authors: Mao Yilin , Zeidouni Mehdi
Published: November 2017

Temperature transient analysis is evolving to implement the production induced thermal perturbations for reservoir and near wellbore characterization purposes. To observe strong temperature signals, temperature well testing often involve high drawdown, which may induce non-Darcy flow effect in the near wellbore region. The existing analytical solutions for temperature transient analysis generally assume Darcy’s law for pressure profiles, which can be invalid in both gas and oil productions. In this study, we derive an analytical solution for temperature transient analysis of slightly compressible fluid producing from a vertical well considering the non-Darcy flow effect. To validate the developed analytical solution, we model the sandface temperature signals analytically and verify the results with numerical simulation conducted under comparable conditions in non-damaged and damaged reservoirs. Good agreements are achieved between analytical and numerical modeling results under different production rates and non-Darcy flow coefficients. The non-Darcy flow effect significantly increases the sandface temperature variations during production, which approach to a constant increment for sufficient long production time. We develop a new permeability estimation method considering the non-Darcy flow effect, which is also applicable for damaged zone property and non-Darcy flow coefficient estimations. Two criteria to apply temperature transient analysis for non-Darcy flow effect evaluation are revealed as critical Forchheimer number and accuracy of the downhole temperature monitoring system. Sensitivity analyses reveal that the non-Darcy flow coefficient impacts the magnitude of the sandface temperature signals while the production rate affects the slope of temperature profiles in a semi-log plot. Based on the findings in this work, we build on the existing characterization procedures for temperature transient analysis and incorporate the non-Darcy flow effect to estimate the permeability and non-Darcy flow coefficient. For the cases presented in this study, the inversion process of temperature transient analysis can accurately estimate the reservoir and damaged zone permeabilities, as well as damaged zone radius (less than 10% errors). We also evaluate the non-Darcy flow coefficients with acceptable accuracies (less than 30% errors) in a field scale. With these improvements, the applicability of temperature transient analysis using analytical solutions can be extended from cases with limited sandface temperature signals of a few degC to stronger signals of 30-40 degC considering the non-Darcy flow effect.

Conventionally, the start-up method of dual-horizontal wells SAGD is steam circulation. During circulation phrase, the minimum circulation time and maximum heat communication uniform profile are expected to achieve high oil production. Generally, circulation phrase takes 2 to 3 months in Canada in high quality reservoir. For the poor quality reservoir, circulation time will be longer, for example, in China it takes 200-300 days. In order to solve the disadvantages about longer preheating time and preheating ununiformity of the conventional steam circulation method, the electric preheating method is researched, super-longer integrated coiled tubing electric heater is put down to the horizontal wells separately to heat oil formation uniformly.

The heating mechanism of electric heating method is mainly based on the high temperature heat conduction. The method is less influenced by the permeability of reservoir and the viscosity of crude oil, and the heating efficiency is high. Studies show that the electric preheating method is uniform along the entire horizontal section, the effective heating inter-communication between two wells can reach to 100% theoretically, and the preheating time can greatly shortened. The optimizing results in Block Z1 of Xinjiang Oilfield indicate that the electric preheating time of SAGD is 90 days while the steam circulation time is more than 200 days and the inter-communication profile is 100%. The cost of preheating start is reduced from 420,000$ of steam circulation to 220,000$.

HBDY is a sandstone reservoir, which is vertically multi-layered, severe heterogeneous, and developed with water flowing channels. The injecting-production well patterns are imperfect. It has high recovery degree, 36.2%, and high water cut, 83.9%. The average reservoir crude oil viscosity is 6.3 mPa.s. The reservoir temperature is 90°C, and the formation water salinity is 10701mg/L. A new particle-type polymer slug combined with a linked polymer gel (LPG) pre-set slug was applied during May, 2014 to Feb., 2016, and technical and economic success was obtained.

The application area is composed of 12 injection wells and 29 production wells, among which 14 producers have got benefit from dual directions or multi directions. Tracer test was applied for accurate identification of areal reservoir heterogeneity. And water injection profiles were also tested to identify inter-layer difference of injectivity. Based on the above, core flooding experiment and numerical simulation were applied to optimize and design the combined slug parameters of new polymer flooding.

Tracer testing showed a relatively large difference of water flooding velocity in different directions within the same well pattern, with the lowest velocity of 1.35 m/d and the highest velocity of 7.04 m/d. It also showed over 30 times of inter-layer water intaking and liquid producing intensity as inter-layer differences. Using produced water to prepare the liquid, the total designed volume of slugs was 0.06 PV, in which the main slug was made of the nanometer-level new particle-type polymer SMG with the concentration of 0.3%, and the pre-set conformance control slug applies LPG with the concentration of 1.2%. During the execution, due to the poor gelling quality of the LPG, the preparing water for LPG slug was changed to clean water, but the SMG slug was still prepared by produced water. SMG diameter was adjusted to mirometer level from nanometer level. So far, the project has obtained cumulative oil incremental of 35,154.4 t and income of 11,469,000 USD. The operation cost per ton oil produced is 12.6 USD, and the input to output ratio is 1:4.9. Even calculated under low oil price of 30 USD/bbl, the input to output ratio can reach 1:3.3. The project is still in the effective duration, and the technical and economic effect is significant.

It has proved by the case study that good technical and economic results can be achieved through new comprehensive EOR techniques for complex mature fields with late-stage development. The scientific nature of the program design and the timely adjustment during program execution play important role in making the project successful. The experience and lessons learned from the case study provide valuable referencing significance for further optimizing and applying the technology.

CO2 emissions can be reduced by storing it in underground geologic formations such as coal seams, mature or depleted hydrocarbon reservoirs and deep saline aquifers. The combination of carbon dioxide enhanced oil recovery and permanent CO2 storage in mature oil reservoirs has the advantage to project economics. In this research, CO2 storage capacity of a CO2 flooded mature oil reservoir was estimated and the contribution of the CO2 injection to oil recovery was determined by conducting a full-field compositional simulation study. Detailed reservoir characterization study was done to build the geologic model. Reservoir fluid was characterized by sticking laboratory observations. 3-Parameter Peng Robinson EOS was used. Fugacity equilibration method was used to calculate CO2 partitioning between oil and gas. Performing the study in a CO2 flooded reservoir increased the reliability of the predictions by accurately history matching the 30 years of production and 10 years of CO2 and water injection periods. Simulation results showed that applying the CO2 storage project in an almost depleted oil field should increase the field's life and high amount of CO2 should be sequestered. Most of the sequestered CO2 was trapped by structural and stratigraphic trapping mechanism and contribution of solubility trapping mechanism is lower.
