Shallow Gas Identification using LWD Monopole Sonic: A-non Radioactive for Safe and Effective Logs Acquisition in Tunu Field, Mahakam Delta

The Tunu field is a swamp giant gas field located in the Mahakam Delta, East Kalimantan. Stratigraphically, this field has an anticline structure with three main intervals; Tunu Shallow Zone (TSZ), Fresh Water Zone (FWZ), and Tunu Main Zone (TMZ). Shallow gas reservoirs of TSZ have been produced since 2008, following the production of TMZ in the 1990s. Drilling targets in the shallow gas reservoir decreased significantly due to limited reservoir targets, high inclination wells and a low oil price environment. The utilization of radioactive source logging (density and neutron) on Logging While Drilling (LWD) tools is not recommended to be performed in open hole mode for operational and safety issues (e.g: tool stuck). Thus, LWD Monopole sonic is chosen as a replacement of LWD Neutron-Density logs and helps to differentiate between shallow gas potential and coal lithology which is the main challenge in TSZ at interval depth above 1200 mSS. The methodology utilized sonic semblance (STRA) and compressional slowness (DTc) data at real-time and memory data logs, so early decision can be made in drilling mode. In a gas-bearing reservoir, both semblance and slowness are missing, while in coal it produced strong semblance. In order to differentiate carbonate lithology, additional data, such as cutting, calcimetry, drilling Rate of Penetration and Gas While Drilling are utilized. During 2018-2020, 5 wells have been drilled using LWD Monopole sonic together with LWD GR-Resistivity-Neutron-Density (Triple Combo) to calibrate the fluid interpretation and 3 trial wells with only GR-Resistivity-Monopole Sonic. As a result, LWD Monopole sonic is able to differentiate between Gas and Coal based on semblance and slowness with a success ratio up to 80%. This LWD Monopole Sonic provides a non-radioactive solution for safe and effective logs acquisition for shallow gas identification that could be applied in oil and gas fields outside Mahakam.

Modified Road Traffic Signs in the South African Linguistic Landscape

Drawing on the linguistic landscape material of modified road traffic signs in different areas of South Africa, the article illustrates how modified traffic road signs continue to have situated contextual meanings regardless of altered physical placement or content. Drawing on semiotic repurposing this article argues for an extended definition of situated semiotics that takes into account repurposed signs. A fluid interpretation of ‘situatedness' will broaden the scope of what is perceived as situated semiotics and discourage the use of delinquent categories such as ‘transgressive' semiotics for ‘out of place' semiotics.

The mediating role of medical professionalism on financial self-interest GPs

BackgroundWhile no normative definition exists, medical professionalism emphasises a set of values, behaviours and relationships that underpin public trust in a physician. The empirical setting for this study is the Irish health care system where GPs receive income through a unique mix of private fee income and state funded capitation. GPs’ income per patient has fallen by 33% under state schemes between 2008 and 2013 due to changes in health policy and national fiscal constraints.AimThis paper examines how general practitioners conceptualise and operationalise medical professionalism and financial self-interest in the Irish healthcare system.MethodTo address this research aim, a historical documentary analysis (2009–2016) of national and medical newspapers was used to investigate GPs’ expressions of medical professionalism and financial self-interest.ResultsThe vagueness of language in differing definitions of medical professionalism may lead to a GP having a fluid interpretation depending on the situation. While general practitioners expressed core humanistic values, such as empathy and compassion, the expression of altruistic values were limited when practitioners indicated there was constraint on the financial resources of a practice.ConclusionCentral to the analysis of a medical practitioner’s treatment of patients and receipt of fee income is the tension between medical professionalism and financial self-interest. Developing an understanding of this tension has implications for those undertaking healthcare policy initiatives and the recruitment and retention of general practitioners in primary care.

Occupational dream pursuit: decision making and consumption behaviors

Purpose The purpose of this study is to examine the stages involved in occupational dream pursuit (ODP). In this study, dreams are studied in the context of life-changing, occupational endeavors. The judgment and decision-making that fuels the process and the consumption motives that appear throughout the various stages of the journey are examined through the narratives of individuals living out their career-related dreams. Design/methodology/approach Open-ended interviews were conducted with individuals who were embarking on a life-changing career attainment experience. The narratives of these informants uncovered psychological, social and behavioral aspects of the dream pursuit process. Findings Through the informants’ narratives, common themes emerged with respect to the ODP journey, and these themes offered a fluid interpretation of the stages involved in the dream pursuit process: revelation, inciting action, development, maintenance and evolution. At each stage, specific consumption motives and behaviors predominate. These themes, including the consumption, psychological and developmental processes that take place at each stage, are discussed through the narratives of the informants. Research limitations/implications This study highlights the role of positive emotions, personal growth, consumption motives and behaviors in ODP. Originality/value Dreams give individuals a sense of purpose and being. Although conventional wisdom acknowledges the importance of dream actualization, limited behavioral research has explored the nuances of ODP with regard to decision-making and consumption.

Bridging the Archival-Ethnographic Divide: Gender, Kinship, and Seniority in the Study of Yoruba Masquerade

This study juxtaposes the observations and interpretations of a twenty-first-century ethnographer with those of nineteenth-century Christian missionaries to rethink interpretations of the practice of gender in precolonial West Africa. The article uses the evolving relationship between an ethnographic researcher and a group of contemporary female ancestral masquerade chiefs to reflect on the ways in which generations of missionaries and scholars have interpreted the gendered construction of power. It critiques previous writers for assuming sex and gender in Yoruba culture to be fixed, and argues for a more fluid interpretation of the gendered identities of the observer and subject being observed.
