... in forecast mode. The time between the end of the former history and the present time was simulated in such manner. Analysis of wellbore storage from well tests revealed values much higher than the theoretic ones computed considering wellbore geometry without fractures. This is explained considering the karst...

... flow equation: = = (Eq-1) [5] Skin Factor. The skin factor or S term is usually defined as a zone of reduced formation permeability near the wellbore. Drilling and completing a well normally result in reduced 1 formation permeability around the wellbore. These decrease in permeability can be caused...

... the wellbore and can suit only one objective: to identify leak point in the primary barrier. Because of mechanical threshold, spinner has limitation of minimum flow rate through leak point to be detected. Temperature log is the oldest technique for well assessment. This is a very powerful tool for well...

... consecutive real-time recordings of wellbore temperature profiles to be made throughout the whole duration of a DST, at high temporal, spatial and thermal resolutions. These transient data were used to create a detailed 3D map of the wellbore thermal response. Using this technology, simultaneous Joule-Thomson...

... and eventually ending well production, especially from depleting reservoirs, as water accumulates into the wellbore. Liquids can accumulate in a gas well through a variety of mechanisms. Usually, the gas produced from a reservoir is not dry, but it has an associated liquid phase. In some cases, liquids can come...

... ABSTRACT Inorganic scale formation decreases production or well injectivity efficiency in oil and gas reservoirs due to permeability reduction near wellbore and eventually plugs production pipelines and wellhead facilities. The existence of these depositions in the reservoir dramatically...

... on the transport of cuttings. These models were developed in the frame of the large research project gebo focused on the optimization of high pressure-high temperature (HPHT) wellbores. Due to the nature of the research goals, these models did not require real-time capabilities. Therefore, the main challenge...

... efficient communications are built between the wellbore and the reservoir. In spite of its contribution to high production rate, technical restrictions and public concerns pose many barriers to carry out hydraulic fracturing. A recently revived technique called water-jet-technology utilizes water-jet under...

After three unsuccessful attempts using conventional drilling methods resulted in two sidetracks and a well suspension, the North Sea operator looked for alternative means to satisfy the intended well construction objectives. Drilling with Liner (DwL...

... and noise logs. So far, the Production Logging Tool (PLT) approach has been considered essential to identify production/injection zones and to recognize the type of fluid at down-hole conditions only in the wellbore. Likewise, cement log used to evaluate cement integrity is blind through tubing or multiple...

The challenge was the review of the original well design to take advantage of the combined application of continuous mud circulation and wellbore strengthening to improve the operational...

... Abstract A significant function of drilling fluids is reduction of frictional forces between the wellbore and the drill string. New techniques in drilling and completions are being used to drill horizontal wells in unconventional resources. Because these frictional forces can potentially limit...

..., completion and multi-stage fracturing of horizontal wellbore have contributed to vast increases in oil and gas production in unconventional reservoirs. Oil and gas production from ultra-low-permeability reservoirs is economically feasible and accomplished using these technologies, which substantially...
