AbstractPulmonary tuberculosis (TB) in children is a neglected global health problem, with an increasing proportion of TB cases in Indonesia. Children with TB are most often impacted by TB transmission in the population at large, especially adult TB that exists in the child’s household. This study aimed to find protective factors that can keep children healthy despite household adult TB contacts. This study reports on 132 respondents with a case-control study conducted at nine referred hospitals and several health centers based on medical records at Special Region of Yogyakarta Province. The study lasted from January to December 2014, while the data analysis was used by both of bivariate (chi-square) and multivariate (multiple logistic regression) analysis. The study found that healthy houses, especially those with healthy bedrooms and fewer exposures to adult TB sufferer, influenced by confounder variables, protected children from TB even though they were exposed to adult TB in their environment. Longer periods of living together is not a risk factor for children to contract TB when living with adult TB patients at home. However, this risk increases with frequent exposure among children to adult TB patients at home. AbstrakTuberkulosis paru (TB) pada anak kian menjadi masalah kesehatan global yang masih terlupakan seiring dengan peningkatan proporsi TB di Indonesia. Penularan penyakit ini di populasi umum seringkali berdampak pada anak, terlebih ketika kontak TB terjadi di rumah tangga. Penelitian ini bertujuan untuk memperoleh faktor protektif sehingga anak tetap sehat meskipun memiliki kontak dengan penderita TB dewasa serumah. Penelitian ini dilakukan dengan pendekatan kasus-kontrol pada 132 responden anak yang berasal dari delapan rumah sakit rujukan dan beberapa puskesmas di Provinsi Daerah Istimewa Yogyakarta. Penelitian dilakukan dalam periode Januari hingga Desember 2014 yang hasilnya dianalisis dengan uji bivariat (kai kuadrat) dan multivariat (regresi logistik ganda). Hasil penelitian menunjukkan bahwa rumah yang memenuhi syarat kesehatan, yakni ruang tidur yang sehat, serta paparan yang jarang diterima dari penderita TB dewasa mampu memproteksi anak agar tetap sehat meskipun tinggal serumah dengan penderita dewasa penyakit ini. Penelitian ini menyimpulkan bahwa lama tinggal bersama bukanlah faktor risiko penyakit TB pada anak.Hal ini karena meskipun lama tinggal bersama antara penderita TB dewasa dengan anak, namun apabila memiliki paparan yang jarang, hal ini pun tidak signifikan menjadikan anak untuk terkena TB.

Abstract
Matrix and fracture permeability of carbonate rich tight cores from Horn River basin Muskwa, Otter Park, and Evie shale formations were measured before and after exposing the core samples to spontaneous imbibition using dilute acid (1 or 3 wt. % HCl acid diluted in 10 wt. % KCl brine). Permeability and porosity were measured at varying net stress of 1,000 psia up to 5,000 psia. Brine and dilute acid imbibition effect on proppant embedment, rock softening/weakening, and fracture roughness were assessed. The following are some of the experiments observations: (a) formation damage due to water blockage of water-wet shales can be improved by adding dilute HCl acid or using hydrocarbon based fracturing fluids; (b) matrix permeability of clay rich or calcite poor shale samples are usually impaired / damaged by dilute acid imbibition; (c) matrix permeability and porosity of calcite rich of shales usually improved with dilute acid imbibition; (d) effective fracture permeability of unpropped calcite rich shales are reduced by dilute acid imbibition; this is because of "rock softening" and "etching/smoothing" of fracture roughness on the "fracture faces". Nevertheless, dilute acid imbibition is less damaging than brine (slick water) imbibition; (e) acid injection instead of acid soaking/imbibition with proppant can optimize matrix permeability or Stimulated Reservoir Volume (SRV) of carbonate rich shales; (f) proppant embedment is caused by both brine (slick water) and dilute acid imbibition and can be minimized by resorting to low-concentration acid in such reservoirs; and (g) significant permeability and porosity hysteresis were observed due to proppant embedment during brine and dilute acid imbibition.

Abstract
One of the most important hydrocarbon resources in the Western Canadian Sedimentary Basin (WCSB) is the Montney tight shale formation, which extends approximately 55,000 square miles from northeast British Columbia to northwest Alberta. Operations in the Alberta deep-basin Montney have proven this area to be one of the continent's most productive unconventional resource plays. As part of the field development plans, cores are cut from the reservoir rock to directly measure source rock properties through analysis of core samples and calibrating wireline logs with data extracted from the core samples.
The subsurface geology of the upper hole section in this particular area is complex, where reactive, swelling, and fissile shale as well as coal beds and lost-circulation zones extend across 2700 m of the openhole section. As such, historically in this field, the Montney has been cored using a weighted oil base system incorporating water contamination into the core; if zero water contamination is mandated, casing is run into the reservoir ahead of the coring section to allow coring with base oil, which leads to smaller core sizes. Additionally, coring operations can require several days when conventional coring technology is applied because of the multitude of necessary trips into and out of the hole.
Well engineers applied a systematic approach to achieve new targets by incorporating the latest available technologies and drilling techniques in the industry into a coring program while also optimizing well structural designs by minimizing use of casing strings. This allowed achieving the project's primary objectives of cutting larger-sized cores with no water contamination using minimal planned trips.
This paper discusses how managed pressure drilling (MPD) and wellbore strengthening techniques, as well as new coring technologies, were analyzed, planned, and incorporated into this project. This led to the successful execution of an optimized, cost-efficient well structural design with 100% core recovery and no water contamination while. At the same time, a new record was set in terms of the longest core length cut in one run in onshore North America.
Accounting for Production Shadow in Infill/DUC Well Hydraulic Fracturing Modeling and Calibration

Abstract
The stress state at infill wells changes as a function of production from the existing producer. Understanding spatial and temporal in situ stress changes surrounding drilled uncompleted (DUC) wells or infill wells has become increasingly important as the industry works through its inventory of DUC wells and redesigns infill wells with an engineering approach.
Optimizing infill/DUC well completion designs requires an estimation of the altered in situ stress state. This study presents the concept of a "production shadow" as the stress change in four-dimensional space, affecting well performance and optimal well configurations for pad development. The production shadow accounts for the compound effects from both hydraulic fracture mechanical opening and stress-state alteration from depletion.
This paper details an Eagle Ford case study integrating production shadow effects into the parent and infill well hydraulic fracture modeling as well as "frac hit" analysis. The production shadow influences the degree of fracture complexity developed by the infill/DUC well stimulation. Understanding and accounting for the production shadow are critical in engineering to establish and preserve an optimal connection of the induced stimulated fracture network to the wellbore.

Abstract
The optimistic outlook of the petroleum E&P industry, especially with regard to the re-balancing of oil and natural gas prices, has led to a renewed interest in tight gas and liquids-rich plays, more specifically in the Niobrara and Codell formations in the Denver-Julesburg (DJ) Basin. Through the use of post-stimulation completion diagnostics, insights have been obtained that can be utilized to optimize future hydraulic fracturing completions.
Formations with less than one millidarcy permeability require reservoir stimulation in order to economically produce oil and gas. Engineers will often optimize a well's completion, spacing and hydraulic fracturing treatments to maximize its return with respect to cost. This paper will illustrate the use of post-stimulation completion diagnostics in identifying trends that are associated with effective completions in the Niobrara and Codell formations. In addition, case histories will be presented which illustrate methods that have increased the overall completion effectiveness in relation to proppant placement, wellbore deliverability and, ultimately, increased production performance.
A horizontal well database (&gt; 350 wells) was compiled to identify effective completion trends across the Niobrara and Codell formations. By employing proppant and fluid-based tracers, hydraulic fracture geometry, well deliverability and production performance were measured to identify trends that increased overall completion effectiveness. Primary completion results highlight areas including, but not limited to, effective proppant placement, full lateral production, frac stage length and containment, perforation cluster/sleeveefficiency, wellbore lateral length and inter-well communication between Niobrara and Codell formations.
Many of the insights gained through this use of post-stimulation completion diagnostics in the Niobrara and Codell formations have led to increased completion optimization, production enhancements and field-wide cost reductions.
Improving Oil Recovery in Unconventional Liquid Reservoirs by Soaking-Flowback Production Schedule with Surfactant Additives

Abstract
Improving oil recovery from unconventional liquid reservoirs (ULR) is a major challenge. We have demonstrated in previous laboratory studies the impact of surfactants on spontaneous imbibition and oil recovery by means of wettability alteration and interfacial tension (IFT) reduction. Thereby, fracture treatment performance and consequently oil recovery could be improved by adding surfactants to stimulation fluids when a soaking-flowback production schedule is applied. This study evaluates the ability of different groups of surfactants to improve oil recovery in ULR by experimentally simulating the fracture-treatment to represent surfactant imbibition in an ULR core-fracture during a soaking-flowback. Also, we analyze the effect of wettability and IFT alteration on the process. A core-flooding system was combined with the computer tomography (CT) scanner to dynamically visualize the fluid movement as it penetrates the ULR sample in real-time as well as compare oil recovery between surfactants and water without additive. Wolfcamp sidewall cores were longitudinally fractured and loaded into an aluminum-carbon composite core-holder. Two different types of surfactants, anionic and nonionic-cationic, as well as water without surfactants, were injected through the fractures, at reservoir conditions, to evaluate their effectiveness in penetrating into the fractures and recovering oil from ULR core. Then, a soaking-flowback production scheme was used to simulate fracture-treatment and flowback. Changes in core wettability and IFT were determined by contact-angle and pendant-drop methods. Core-flooding results showed that surfactant solutions had higher imbibition and recovered more oil from liquid-rich core compared to water alone. The soaking-flowback production schedule aided by surfactants was able to recover up to 14% of the original oil in place (OOIP) whereas water alone recovered up to 2% of the OOIP. These observations qualitatively agree with wettability and IFT alteration measurements. Core wettability shifted from an original oil-wet to a final water-wet state and surfactants reduced IFT to moderately low values. The results showed that the addition of surfactants to completion fluids and the use of a soaking-flowback production scheme could improve oil recovery by wettability alteration and IFT reduction, maximizing well performance after stimulation. These findings give important understanding for designing completion fluid treatments and flowback schedules for ULR.
Improving Drilling Reliability Through Advanced Drilling Dynamics Models

Abstract
Recent advances in drilling and oil & gas extraction have altered the mindset among drilling engineers. One example is the recent trend to drill faster and minimize Non-Productive Time (NPT). This usually requires minimizing changes to the Bottom Hole Assembly (BHA) and improving its reliability. Directional drilling tools such as mud motors and Rotary Steerable Systems (RSS) have become a main stay in minimizing NPT. Moreover, understanding in planning stages the tools’ working envelope in downhole environment, is critical to reducing NPT. Conventional surface testing, however, have significant constraints when trying to determine the performance envelope of directional tools and BHAs.
Advances in numerical modeling enable evaluation of BHA performance under much more realistic downhole conditions. This paper discusses the advancements in the evaluation of directional drilling tools using advanced Time Domain Analysis (TDA). For example, time domain models allow exploration of the full range of BHA response under downhole conditions including the effects of formation changes. Drilling dysfunctions including stick-slip, whirl, and dynamic lateral vibrations can be realistically predicted before drilling. TDA models allow drilling engineers to explore the design space and also explore operating conditions to optimize performance and reliability of the BHAs.
This work describes a newly implemented TDA model based on rigid body dynamics (RBD) solved by finite element methods (FEM) to model drilling dysfunctions. The approach is significantly more accurate and faster compared to conventional models. Also shown is how the TDA model successfully predicted several drilling dysfunctions before drilling and reduced NPT. It is also used to analyze post drilling job cases and explain issues observed in the field.
