... Abstract Drilling wells with minimum risk and optimizing well placement with the least possible cost are key goals that companies strive to achieve. The major contributor to the successful execution of the well is the quality of the drilling program. Well design is a complex process, which...

... completion time of 181 days. The objective was to optimize the well design, bottomhole assemblies (BHAs), and casing points to optimize drilling operations and reduce costs. Due to the 17.5-in. and 12.25-in. sections being drilled vertical, the main optimization focus of the project began in the 8.375...

... pressure was proposed for well design. Based on postdrill analysis, the actual pore pressure was within the uncertainty model which helped to make decisions on well design in realtime. reservoir geomechanics HPHT complex reservoir Artificial Intelligence Upstream Oil & Gas high pressure high...

... of this concept was successful. Resulted savings include eliminating the liner installed in the standard well design, saving rig days, and eliminating expandable liners in future re-entries. The deployment of the developed system has resulted in significant cost savings, allowed for more operational efficiency...

... that the intent is to document and share experiences and lessons learned in Brunei deepwater wells within the industry. This would enable the execution workflow and well design to be continuously improved for a safe and cost-efficient delivery of the wells. wellbore integrity Reservoir Characterization...

... cycle was cut in half, which was considered as a breakthrough achievement in the field. With the application of hybrid high-build-rate rotary steering system, the new well design can be executed. Air drilling is chosen to drill through the hard rock in the shortest distance. Using the power rotary...

... to be mitigated by modification of both the on-going drilling plan and the well design. The clearest and most precise information was required. When active surface gas venting was discovered at an adjacent well, an ultrasonic annular integrity survey was commissioned to determine the subsurface source of the gas...

... volumes. Unconventional plays are often characterised by a large number of wells, lower density of subsurface data, large geographical extent and corresponding large range of uncertainty in subsurface parameters. The rapid economic screening of well design and spacing parameters for multiple subsurface...

... that include multiple fracture stimulations in various pay zones to maximize well productivity. The slimhole well design, dynamic completion design, and careful bit design and selection successfully enabled the drilling of these wells with 26% cost savings on the total budget for drilling ten wells ($ 2M per...

.... This presentation is first to demonstrate effective cost saving by reducing well count with case studies in thin oil-rim and compartmentalized reservoirs in Malaysia. It then illustrates the feasibility of further reducing the well construction cost by changing the well design culture and production strategy...

Preservation and exploitation of these fractures to drain the gas from the coal became the focus of production well design. With this in mind, the key risks and uncertainties for the first production pilot...

In addition, Phase I was analyzed in terms of drilling, operational procedures, processes, tools selections and well designs to identify root causes and to learn from them. These studies were then applied to overcome the cannel structural complexities, thus...
