The Australian CleanTech Index rose from 42.97 to 43.89 over the month of February recording a 2.2% gain. This compared to the S&P ASX200 loss of 2.5% and the S&P ASX Small Ordinaries Index gain of 0.7%. The Australian CleanTech 20 rose 2.3% for the month. The CleanTech Index continues to outperform the wider market over each of the longer periods reported in the table below. The 12-month performance now leads the ASX200 by 11.1%. The best performing sub-indices for the month were the Australian Renewable Energy Index with a 3.7% gain and the Australian Waste Index with a 3.6% gain. The weakest sub-index through February was the Australian Environment Index recording a loss of 4.0%. The market capitalisation of the 62 stocks in the Australian CleanTech Index is A$16.7 billion down from the March 2015 record of $18.9 billion but a long way up from its low of A$6.2 billion in July 2012. The month’s performance included 9 companies with gains of more than 10%. The greatest percentage gains were recorded by HRL Holdings (HRL), Neometals (NMT) and RedFlow (RFX). The greatest market capitalisation gain was recorded by Meridian Energy (MEZ). These gains were partially offset by 10 companies recording losses of more than 10% led by GO Energy Group (GOE), Kalina Power (KPO), Traffic Technologies (TTI) and Enerji (ERJ). The greatest market capitalisation loss was recorded by Mighty River Power (MYT).   Get CleanTechnica’s 1st (completely free) electric car report → “Electric Cars: What Early Adopters & First Followers Want.”   Come attend CleanTechnica’s 1st “Cleantech Revolution Tour” event → in Berlin, Germany, April 9–10.   Keep up to date with all the hottest cleantech news by subscribing to our (free) cleantech newsletter, or keep an eye on sector-specific news by getting our (also free) solar energy newsletter, electric vehicle newsletter, or wind energy newsletter.

Since publication of ANSI/NACE MR0175/ISO 15156 in 2003 there has been much debate on the performance of austenitic stainless steels in oil and gas production environments, with researchers recommending relaxation of the ISO 15156 restrictions for this material. This paper describes a recent austenitic stainless steel stress corrosion cracking failure and discusses its implications for the current restrictions of the ISO standard and recently proposed relaxations of these restrictions.

The Karachaganak field is giant oil and gas condensate reservoir. Data collected from numerous wells confirms it is very heterogeneous. Because conventional logs are not sufficient to fully characterize reservoir properties, new technologies and interpretation techniques arc always considered worthy of a trial run when they become available in this remote region. In particular, the operator, KPO, is experiencing serious problems related to wcllbore stability in deviated wells. Those problems occur mostly in the overburden and are related to uncertainly in stress direction and stress magnitudes. Excessive fluid losses while drilling are also a serious issue, and there is a need to identify fracture zones and understand fracture attributes. Finally, estimates of the extent of the formation damage zone (or radial extent of alteration in reservoir intervals) would provide useful information for the design of optimal well completions. Recently, a new advanced-technology, wireline acoustic scanning tool was run in a new well in lhe Karachaganak field to provide 3D formation acoustic properties from all borehole modes (monopole, dipole, and Stoneley) and measurements for near-wellbore and far-field slownesses. Drilling and completion engineers at KPO used the interpretation of this data to help make decisions and identify key geomechanical parameters required for successful operations. Mild stress-induced anisotropy zones were detected in the formation. Some zones of formation damage were identified by monopole and dipole radial variation profiling. Prominent open fractures were detected using shear dispersion analysis and Stoneley propagation - and confirmed by the electrical borehole images. KPO plans to use the acoustic anisotropy information to compute stress magnitude for new-well placement and mud-weight optimization, and for oriented perforation techniques to optimize hydraulic fracturing simulation. The estimation of radial formation alteration may help in designing optimal completions and identifying suitable depth intervals for fluid sampling. Copyright 2010. Society of Petroleum Engineers.

The electronic Permanent Downhole Gauges (PDHG) has traditionally been used in the Karachaganak field to monitor downhole pressures and temperatures, for reservoir management. The overall performance and quality of the data from some of the Permanent Downhole Gauges (PDHG) installed in the Karachaganak field was not satisfactory. Hence, fibre optics has been investigated as an alternative technology due to the reliability, calibration and cost concerns related directly to the Permanent Downhole Gauges (PDHG).

Electro-hydraulic robotic tools that perform well interventions on electric line (e-line) have come of age over the past 10 years and can now be used to accomplish tasks previously done with the use of jointed pipes and/or coiled tubing conveyance system. Examples of such tasks are downhole milling, shifting of stimulation sleeves, etc. Surface real time monitoring and control features are required to ensure that such tasks done by robotic tools are successfully achieved with high accuracies. As the demand increases to use this type of powered devices in a more hostile well environment, service companies have developed technologies to expand their operating range. Starting from late 2013, the robotic technology solution has been used in KPO horizontal sour wells to close stimulation sleeves when required for reservoir fluid management, to convey perforation guns, to convey production logging tools and to mill frac balls and ball seats. This paper will present four case histories of the robotic technology application in the Karachaganak field. It will discuss the advantages of the technologies, the challenges and the future improvement required to further optimize the field operations. Copyright 2015, Society of Petroleum Engineers.
