Topographic influence on stability for gas wells penetrating longwall mining ...legend314
Gas wells that penetrate mineable coal seams may be subject to distress caused by ground movements due to longwall mining. Especially important are the lateral shear offsets and axial distortion, which are most damaging for wellbores. To replicate typical conditions in the Appalachian basin, a geological model that considers the combined effects of topography, weak interfaces between monolithic beds and various mining depths is presented in the foregoing. These conditions adequately represent the principal features of the anticipated response of gas wells that are near-undermined by longwall panels. We examine the magnitudes of longitudinal distortions, lateral shear offsets, delaminations, and vertical and lateral strains along vertical wells drilled to intersect the seam at various locations within the longwall pillar. We analyze the distribution of these deformations and predict areas where the most severe deformation would occur.

Stress analysis is the essence that is needed while planning exploration, drilling and development operations in oil and gas industries. Proper knowledge of Geomechanics will help us to reduce the risk of failure as well as provide a better picture of stresses inside the earth. From Hydrofracturing to directional drilling, stresses play their parts.
This five-day course provides an intermediate level of understanding of the geomechanical factors that affect wellbore instability, sand production and hydraulic fracture design. The course is structured such that upon completion, participants will have understood the value that geomechanics can bring to drilling, completion and production operations and will be able to leverage this value wherever it applies. The course emphasis will be on integrating the topics presented through a combination of lectures, case-studies and hands-on exercises. A special focus will be on how geomechanics knowledge is extracted from routinely acquired well data and how it is applied in the prediction and prevention of formation instability.
Laboratory-scale geochemical and geomechanical testing of near wellbore CO2 i...Global CCS Institute
To highlight the research and achievements of Australian researchers, the Global CCS Institute together with ANLEC R&D will hold a series of webinars throughout 2016 and 2017. Each webinar will highlight a specific ANLEC R&D research project and the relevant report found on the Institute’s website. This is the sixth webinar of the series and presented the results of chemical and mechanical changes that carbon dioxide (CO2) may have at a prospective storage complex in the Surat Basin, Queensland, Australia.
Earth Sciences and Chemical Engineering researchers at the University of Queensland have been investigating the effects of supercritical CO2 injection on reservoir properties in the near wellbore region as a result of geochemical reactions since 2011. The near wellbore area is critical for CO2 injection into deep geological formations as most of the resistance to flow occurs in this region. Any changes to the permeability can have significant economic impact in terms of well utilisation efficiency and compression costs. In the far field, away from the well, the affected reservoir is much larger and changes to permeability through blocking or enhancement have relatively low impact.
This webinar was presented by Prof Sue Golding and Dr Grant Dawson and will provide an overview of the findings of the research to assist understanding of the beneficial effects and commercial consequences of near wellbore injectivity enhancement as a result of geochemical reactions.

Field Development Project : Gelama MerahHami Asma'i
A green field development project located in Sabah Basin comprises the whole upstream field development cycle from geology, reservoir studies to production facilities and economics. The objective is to come out with the best strategy to develop the field starting from our very own effort of reservoir characterization out of log and core data. Under supervision of lecturers, this project was completed as per scheduled.
Among new technical methodologies applied upon the completion this project:
1. Cubic Spline Interpolation Method in bulk volume calculation
2. Monte Carlo probabilistic method in reserve estimation
3. Reservoir Opportunity Index (ROI) method in well placement
Project was assessed by PETRONAS custodians.
Modelling of The Properties of Sand Mould Made of Reclaimed SandIJERA Editor
Modelling of the properties of the sand mould made of reclaimed sand bonded with sodium silicate and cured with CO2 gas is attempted in this paper. Properties considered are Mould hardness and Permeability. Regression models are developed and the correlation coefficient is determined. It is observed that the predictions of the model are matching with experimental values within +/- 5 % error.
Microfracturing is an excellent method of obtaining direct stress measurements, not only in shales, but in conventional reservoirs as well. Recent advances have shown that microfracturing can help improve reservoir management by guiding well placement, completion design, and perforation strategy. Microfracturing consists of isolating small test intervals in a well between inflatable packers, increasing the pressure until a small fracture forms and then by conducting a few injection and shut-in cycles, extend the fracture beyond the influence of the wellbore. Results show that direct stress measurements can be successfully acquired at multiple intervals in a few hours and the vertical scale nearly corresponds to electric log resolution. Therefore, microfracture testing (generally performed in a pilot / vertical well) is an appropriate choice for calibrating log derived geomechanical models and obtaining a complete, accurate, and precise vertical stress profile. This talk describes the microfracturing process and presents several examples that led to increased hydrocarbon recovery by efficient stimulation and/or completion design. Case studies presented range from optimizing hydraulic fracturing in unconventionals, determining safe waterflood injection rates in brownfields, and improving perforation placement in ultra deepwater reservoirs.
