... Abstract A proper deep isolation of high-pressure sour gas reservoirs through Corrosion Resistance Alloy (CRA) tubing had been a real challenge for offshore gas operations owing to the inherent limitations present in all rigless operations needed to accomplish this task. Moreover, the presence...

... Abstract Warning and controlling the water invasion in water-driving gas reservoirs is significant because water invasion will seriously hamper well productivity and gas recovery. Unfortunately, there are few comprehensive methodologies to control water invasion. In this paper, firstly, a water...

... of this study highlight that water blockage is great challenge in tight gas reservoirs. Injecting thermochemical fluids into tight samples reduces the capillary forces significantly, which leads to remove the water accumulation. Therefore, considerable enhancement was observed in the rock conductivity...

... Abstract Many gas reservoirs are water driven. Water supplies an extra mechanism to produce the gas reservoir, but it can create production problems in the wellbore. These water production problems are more critical in low productivity gas wells.Water loads up the gas well, when a lot of gas...

... data to identify and evaluate gas reservoir. The purpose of this paper is to build up some more accurate models to identify gas layer, water layer, gas and water mixed layer. In this study, the pretreatment have to be done, such as environmental correction, core reposition and well log normalization...

... a critical value will cause the elemental sulfur to deposit in the formation, and in turn the gas well productivity will be affected. Accurate prediction of sulfur deposition in the reservoir will help in better manage sour gas reservoirs with potential sulfur deposition problems. In this paper new...

... ) Generalized Equation In this paper, we derive the advance gas material balance equation to account for water encroachment in water drive reservoir, expansion of formation and of residual liquid in overpressured reservoir and gas desorption in CBM and shale gas reservoir in the same simple format...

... act as permeability buffers in some areas of the reservoir. In such a mature carbonate gas reservoir as the Khuff, managing and optimizing the performance of wells represents a challenge for the reservoir and production engineers because of the reservoir heterogeneity created by dissolution process...

... Abstract Shale gas reservoirs have become a major source of energy in the recent years. Developments in hydraulic fracturing technology have made these reservoirs more accessible and productive. Apart from other dissimilarities from conventional gas reservoirs, one major difference...

... Abstract Saudi Aramco's operations cover a wide range of environments, some of which are multilayer gas reservoirs, consisting of thinly-laminated shaly sands. Evaluations based on conventional log data often prove to be inconclusive. Wireline formation testers are routine sources of reservoir...
