Abstract The paper aims to discuss various issues pertaining to gas lift system and instabilities in low producer wells along with the necessary measures for addressing those issues. The effect of various parameters such as tubing size, gas injection rate, multi-porting and gas lift valve port diameter on the performance analysis of integrated gas lift system along with the flow stability have been discussed in the paper. Field X is one of the matured offshore fields in India which has been producing for over 40 years. It is a multi-pay, heterogeneous and complex reservoir. The field is producing through six Process Complexes and more than 90% of the wells are operating on gas lift. As most of the producing wells in the field are operating on gas lift, continuous performance analysis of gas lift to optimize production is imperative to enhance or sustain production. 121 Oil wells and 7 Gas wells are producing through 18 Wellhead platforms to complex X1 of the field X. Out of these 121 oil wells, 5 are producing on self and remaining 116 with gas lift. In this paper, performance analysis of these 116 flowing gas lift wells, carried out to identify various problems which leads to sub-optimal production such as inadequate gas injection, multi-porting, CV choking, faulty GLVs etc. has been discussed. On the basis of simulation studies and analysis of findings, requisite optimization/ intervention measures proposed to improve performance of the wells have been brought out in the paper. The recommended measures predicted the liquid gain of about 1570 barrels per day (518 barrels of oil per day) and an injection gas savings in the region of about 28 million SCFD. Further, the nodal analysis carried out indicates that the aforementioned gas injection saving of 28 million SCFD would facilitate in minimizing the back pressure in the flow line network and is likely to result in an additional production gain of 350 barrels of liquid per day (65 barrels of oil per day) which adds up to a total gain of 1920 barrels of liquid per day (583 barrels of oil per day). Additionally, system/ nodal analysis has also been carried out for optimal gas allocation in the field through Integrated Production Modelling. The analysis brings out a reduction in gas injection by 46 million SCFD with likely incremental oil gain of ~100 barrels of oil per day.

The Relationship

The pursuit of quality service delivery in the public sector management in Cameroon necessitated the decentralisation of public sector management by transferring more power and resources to the local councils. This is in a bid to make them more self-governing. These councils are expected to meet the aspirations of their municipalities by carrying out approved projects efficiently and effectively. In this regard, this paper sets out to investigate the relationship between budgetary control and performance of local councils in Mezam and Momo Divisions of the North West Region of Cameroon, and the challenges these councils encounter in the process of budgetary control. Data was collected through a survey and analysed using the Ordinary Least Square (OLS) estimation technique to regress the relationship between the budgetary control variables and council performance. The empirical results showed that the key budgetary control variables (planning, participation, monitoring and control, motivation, communication, and responsibility) have a positively and statistically significant effect on performance of the councils. Effective performance of local councils in Mezam and Momo Divisions of the North West Region of Cameroon could then be attributed to effective presence of budgetary control requiring the availability of financial resources rationally allocated, qualified and experienced personnel, participation of all responsibility center managers in the planning and control processes, and regular communication and motivation of the council staff.

Gas Recycling

The North Rankin gas field is the first field to be developed as part of the North West Shelf Project and has now been on stream for some two years. With a most likely gas-initially-in-place of 11TCF (308 × 109 m3), it is the largest appraised gas-condensate field in Australia.At the current stage, gas is being produced from one platform (the North Rankin 'A' platform) entirely for domestic consumption. Future development involves the drilling of additional wells to provide gas for export as liquefied natural gas (LNG) to Japan, installation of a second platform, and construction of an additional onshore plant to manufacture the LNG. In addition, a gas recycling project is to be implemented on the North Rankin 'A' platform to increase the recovery of condensate by utilizing spare platform processing capacity available prior to reaching plateau LNG exports.The present paper reviews the development and performance of this major field over the first two years of its producing life. Emphasis is placed on the reservoir pressure performance, particularly in relation to the reservoir geology.

AbstractWe report on the installation and first results of one compact oceanographic radar in the region of Nice for a long-term observation of the coastal surface currents in the North-West Mediterranean Sea. We describe the specific processing and calibration techniques that were developed at the laboratory to produce high-quality radial surface current maps. In particular, we propose an original self-calibration technique of the antenna patterns, which is based on the sole analysis of the database and does not require any shipborne transponder or other external transmitters. The relevance of the self-calibration technique and the accuracy of inverted surface currents have been assessed with the launch of 40 drifters that remained under the radar coverage for about 10 days.

We characterized and analyzed women’s narrative around the idea of becoming asustado (scared)as a cultural way of understanding why children get sick repeatedly or develop illnesses that become increasingly severe, as part of a study carried out in rural communities from the Molinos District, in the North-West of Argentina. We analyze and discuss the implications of becoming asustado for everyday child-rearing and children's health, sociability, and performance in different community endeavors from ethnographic data. We intentionally selected 15 cases elaborated based on 55 semi-structured interviews with 15 women, between 25 and 55 years old, all caregivers of children under 6 years old. Our results show that susto (fright) serves as an explanation for those people who do not fit with cultural expectations about their phenotype and social performance. Also, it is a culturally acceptable way of dealing with both physical and mental stress.

Orientation: Employees are a source of competitive advantage for organisations and human resource management seek to promote employee efficiency. One of the tools organisations utilise to achieve this goal is performance appraisals.Research purpose: The purpose of this study was to investigate the weaknesses in performance appraisal and to determine whether it is politicised in the North West Department of Health and Social Development in South Africa.Motivation for study: Many organisations either ignore the existence of politics in the appraisal process or assume that its impact can be minimised if they refine their appraisal instruments. Executives admit that, in appraising others, they often intentionally avoid meeting the goal of accuracy in favour of achieving goals that have more to do with exercising discretion and maintaining departmental effectiveness. Ironically, these same executives lament that the appraisals they receive often do not accurately represent their abilities and performance (Gioia & Longenecker, 1994).Research approach, design and method: Self-administered questionnaires were used as a means of collecting data and analysis was done through the use of the Statistical Package for the Social Sciences (SPSS).Main findings: The results of the study showed that respondents believe that performance appraisals are highly politicised.Practical/managerial implications: If used effectively, performance appraisals may improve employee productivity and efficiency as well as motivation and performance. However, if performance appraisal is perceived as unfair and political, it can diminish rather than enhance employee attitudes and performance.Contribution: Amongst others, it is recommended that managers should consider separating assessment for development and assessment for rewards.
