First experience of lymphoscintigraphy use in early stages of breast cancer
Authors: Vatankha S S , Aliev F Yu 
Published: April 2017

Aim. To evaluate efficacy of radioisotopic methods in detection of metastatic involvement of sentinel lymph nodes for choosing further theurapeutic tactics.
Methods. The study group included 23 females with confirmed breast cancer. Sentinel lymph nodes were detected by isotope 99mTc Nanocolloid and blue dye in General Electric gamma camera (USA).
Results. In all cases patients’ age was 45 to 60 years. In 16 (69.5%) cases the tumor size was below 5 cm which corresponded to clinical stage 2, in other 7 (30.5%) patients the tumor size was below 2 cm. Positive results with the use of lymphoscintigraphy were revealed in 6 (26%) cases, all results were morphologically confirmed straight after lymph node removal. In 5 (83%) cases metastatic involvement of the node was observed in stage 2 cancer. Such patients were immediately referred to radical mastectomy with radical lymph node dissection. In other cases pathological accumulation of a radiopharmaceutical was not observed. Only in one case after removal of such node its metastatic involvement was confirmed histologically. So the frequency of false negative results was 4.3%. Respectively, status of sentinel lymph nodes in breast cancer reflects the status of lymphatic collector with 95.7% accuracy.
Conclusion. The biopsy results demonstrated high diagnostic value of lymphoscintigraphy for detection of breast cancer metastases to sentinel lymph nodes (sensitivity 86%, specificity 100%): the method can be successfully used in early stages of breast cancer and also in case of negative results of conventional diagnostic methods (ultrasound, roentgen mammography).

RESUMO: As rearticulações contemporâneas do neoliberalismo têm promovido o aprofundamento das transformações na instituição central da modernidade. O Estado e todas suas instituições, e aqui se destaca o Poder Judiciário, tem passado por importantes redimensionamentos. Neste contexto, o presente artigo, construído por meio de uma revisão bibliográfica interdisciplinar, enfrenta o conjunto de câmbios que passa a jurisdição, dentro do cenário multifacetado de crises estatais. Partindo do reconhecimento de que na globalização tem-se a instauração de uma nova racionalidade que “orienta o mundo”, traz a reflexão sobre a forma como o espaço judicial tem tido redefinidas as funções e a operacionalidade, em face das demandas por uma gestão eficiente. A hipótese de trabalho envolveu a compreensão de que as mudanças pelas quais passa o sistema de justiça estão orientadas por discurso que sacrifica a justiça sob o primado do aumento da produtividade e diminuição das despesas. Assim, a racionalidade econômica-concorrencial passa a impor diretrizes gerencias ao sistema de justiça, o que se repercute no sacrífico da base de legitimidade material de atuação.PALAVRAS-CHAVE: Neoliberalismo, Crises do Estado, Jurisdição. ABSTRACT: The contemporary neoliberalism rearticulations has further the deepening of the central institution of modernity. The State and all its institutions, and here the Judiciary Power enhance, has been through important resizes. In this context, this paper, built by an interdisciplinary literature review, faces the exchange set that jurisdiction passes, inside a multifaceted scenario of State Crisis. Starting from the recognition that in the globalization there are the establishment of a new rationality that “guides the world”, brings the reflection about how the shape of the judicial space has been redefined it functions and the operability, in view of demands for an efficient management. The working hypothesis has involved the understanding that the changes that the justice system has been through are guided by a speech that sacrifices the justice beneath increase of the productivity and the reducing expenditure. So, the economic-competitive rationality starts to impose management guidelines to justice system, which impact on the sacrifice of the basic legitimacy of acting material.

Issues and Challenges With Controlling Large Drawdown in the First Offshore Methane-Hydrate Production Test
Authors: Sakurai S.. , Nishioka I.. , Matsuzawa M.. , Matzain B.. , Goto A.. , Lee J. E. 
Published: April 2017

Summary
The first offshore methane-hydrate production test was conducted in the Eastern Nankai Trough area of Japan in 2013, subjecting a gas-hydrates reservoir to large drawdowns by reducing bottomhole pressure (BHP) for in-situ dissociation of gas hydrates. This pioneering test has proved the feasibility of the depressurization method through demonstration of gas production from a deepwater gas-hydrates reservoir. Approximately 119 500 std m3 of gas was produced during a continuous flow period of 6 days. However, reservoir response to a range of drawdown conditions was not attainable, which is important for reservoir evaluation, because drawdown became uncontrollable after unintended water production through the gas line occurred.
Gas and water released from the dissociation of gas hydrates were separated by use of a downhole gas-separation system. The separated gas and water were produced to surface by means of two dedicated gas and water lines. Drawdown was executed by pumping out water into the water line by use of an electrical submersible pump (ESP). Drawdown control was designed to regulate the liquid level (or hydrostatic pressure) in the gas line by controlling the ESP frequency and the water-line surface backpressure.
Analysis of production data supported by flow simulations indicated that continuous water production through the gas line was the main reason for the loss of drawdown control. The trigger of the water production was that the water column in the gas line reached surface because of the rising water level resulting from the produced gas, which also lightened the water column and lowered the BHP. Consequently, the continuous water production made it difficult to regulate the drawdown as intended.
The analysis concluded that the risk of water production through the gas line could be significantly lowered if a choke valve was installed at the surface gas line and/or the ESP had high tolerance to the presence of free gas. This first field trial has provided valuable information in understanding the methane-hydrate production system to further improve/develop strategies in controlling large drawdown in the system.
Temperature Correction in NMR Logging While Drilling
Authors: Coman Radu , Tietjen Holger 
Published: April 2017

Abstract
The formation temperature affects numerous logging measurements including nuclear magnetic resonance (NMR) data. Obtaining NMR porosity requires the multiplication of the raw NMR signal by a factor that includes the temperature in the sensitive volume. Typically, the temperature of the mud is used as a proxy for the temperature in the sensitive volume. However, if the two temperatures are not equal, the temperature effect reduces the accuracy of the NMR porosities. In some environments (e.g., NMR logging while drilling in deep wells) the NMR temperature effect might as large as 10% of the total NMR porosity.
The main challenge in correcting the NMR porosity for temperature effect is the estimation of the temperature in the sensitive volume. By assuming that heat conduction is the main heat transfer mechanism, the formation temperature can be estimated by solving the heat equation in the proximity of the borehole. To reduce the computational time, a level-based approach is used, whereby the size of the model is controlled by the borehole size. Moreover, by assuming that the temperature in the axial direction is constant within the sensitive volume, the 3-D temperature distribution is reduced to a 1-D distribution (in the radial direction) that can be numerically computed by a finite-difference (FD) scheme.
The temperature distribution around the borehole depends on several parameters including the undisturbed temperature of the formation, the borehole size, the thermal diffusivity of the formation, the time since drilled, and the whole history of drilling mud temperatures. A level-by-level FD computation of the formation temperature is too slow for practical use. Fortunately, the FD computation can be fully replaced by a fast analytical computation based on two pre-computed maps. The maps contain dimensionless formation temperature as function of dimensionless time and dimensionless radius. The first map is for the continuous cooling case (mud temperature is constant and lower than formation temperature), while the second map is for a so-called impulse cooling case.
This paper presents the theoretical background of the NMR temperature correction, several FD schemes and the quasi-analytical approach used for the computation of the formation temperature, numerical examples illustrating the computation of the formation temperature for several cases (e.g., a logging-while-drilling run and a logging-after-drilling run), and a temperature correction workflow for NMR logging data.
Development of Inhibitive Water Based Drilling Fluid System with Synthesized Graft Copolymer for Reactive Indian Shale Formation
Authors: Kumar Saket , Jain Rajat , Chaudhary Pulkit , Mahto Vikas 
Published: April 2017

Abstract
Wellbore instability in shale formations is one of the major problems with water based drilling fluids. The wellbore instability may escalate drilling costs and time. The swelling and dispersion of shale inside the wellbore may lead to high torque, drag, pipe sticking, and additional reaming and borehole enlargement problems. The synthesized graft copolymer is characterized by FTIR, and FESEM techniques. The graft copolymer exhibited superior rheological and filtration properties in the developed drilling fluid system due to increased hydrogen bonding and synergistic effects. The graft copolymer based drilling fluid system has excellent shale inhibition property as compared to PHPA polymer. The shale recovery and slake durability index of graft copolymer based system is higher than PHPA system. This is achieved due to formation of a film-like barrier on the shale surface in presence of graft copolymer, thus restricting the entry of water molecules and solid particles into the shale. The developed system has low reactivity with the core sample as revealed by core flooding studies.

Abstract
An inflow performance relationship (IPR) curve is a mathematical tool used to predict the production of the well throughout its lifetime. This curve is plotted for bottom hole flowing pressure against production rate. An inflow performance curve is presented considering the gas reservoirs where permeability alteration due to pressure is introduced. Results are compared with conventional curves which are based on constant permeability. The new approach considers the permeability of the reservoir as a function of pressure. In addition, modified Kozeny-Carman equation is employed to take care of the variation in porosity, Cementation factor, Shape factor, Lithology factor. The proposed approach considers the porosity and cementation factor as a function of pressure based on compressibility of the rock matrix. The numerical solution shows the over prediction of the gas flow rate with reducing bottom hole pressure, by conventional IPR based on constant permeability. The pseudo pressure equation is considered and the conventional IPR curves are compared with the two proposed models. The first model considers only the porosity as a function of pore pressure whereas the second model considers both porosity and cementation factor as a function of pore pressure. For validation, two field case studies are presented for vertical wells in a gas reservoir. Gas flow rates predicted by suggested models are same as that of conventional IPR at average reservoir pressure. On contrary, the IPR curves for both models shifted left due to the low gas flow rates obtained. The most significant finding is that porosity has a greater effect on permeability compared to the cementation factor and thus on IPR curve. The first model considers only the effect of porosity on pressure, shows significant deviation in IPR curve due to a decrease in flowing bottom hole pressure resulted due to production from the gas reservoir. The second model considers both porosity and cementation factor as a function of pressure is more accurate and recommended for inflow performance predictions.

Published: April 2017

Abstract
In the present paper, numerous stuck pipe events were carefully studied in wells drilled in the Kingdom of Saudi Arabia between 2013 and 2014. Stuck pipe events were analyzed per different hole sections (from 34 in. to 5 7/8 in.) and it was noted that overall the number of stuck pipe events were less for the top hole sections. Therefore, the focus of the study was to evaluate the utilization and effectiveness of Drilling Jars in the top hole sections 34″, 28″ and 22″ during stuck pipe events.
The data was collected from Saudi Aramco Stuck Pipe database and limited to new wells, a total of 42 fields and 1026 wells were reviewed. After that, each stuck pipe event was classified according to field name and to the respective hole size where the incidents occurred. A detailed and comprehensive study was conducted for each stuck pipe incident independently, reviewed daily drilling reports and determined the utilization of the Drilling Jars as well as the effectiveness to free the drill string during the stuck pipe incidents.
Classifying the stuck pipe events and analyzing the results, showed that the effectiveness of Drilling Jars in the top hole sections was uncertain. For the 34″ and 28″ hole sections, the effectiveness of Drilling Jars was minimal. For the 22″ hole sections, it showed higher number of utilization and effectiveness. The study concluded that the use of Drilling Jars in the 34″ and 28″ hole sections were ineffective, therefore it was recommended to eliminate the use of Drilling Jars for the respective hole sections across drilling operations in KSA. This decision will result in significant savings, and help to free up service provider resources for use in other hole sizes.
The research became a useful reference in defining the utilization and effectiveness of Drilling Jars across Saudi Aramco Operations. Drilling Engineers are encouraged to optimize the use of drilling equipment in the bottom-hole assembly, to improve efficiency and reduce drilling costs.
