After fracturing, CO 2 realizes energy supplement and gas/oil replacement in the formation, and realizes CO 2 storage...

... Abstract Acid stimulation treatments are typically designed using a combination of experience, available field/lab testing data and a stimulation design software that ties it all together. The final design, given the large degrees of uncertainty, requires multiple iterations to arrive...

... structural and geomechanical analysis to capture the variability of key reservoir properties and the affecting factors including well-to-well interference. Following the analysis, a new optimal stimulation workflow and new production practices were initiated to achieve effective and economical wells...

... Abstract "M" is an undeveloped thin and tight carbonate reservoir consisting of four porous bodies isolated by the presence of intra-dense layers. The prominent layer is four feet of thickness. Applying conventional acid stimulation in "M" has been ineffective to increase wells productivity...

... Abstract Increasing the horizontal lateral length of a shale gas well is often seen as a productivity improvement and project economics solution but challenges completion options. Long horizontal wells restrict popular plug and perf (P&P) stimulation techniques. Access to the toe section...

... within the region, low complexity multilateral junctions – such as open hole laterals – in which offline stimulations have been performed, have resulted in limited production uplift or issues with junction integrity resulting in a short well lifetime. These latter issues become more apparent in weak...

... by low porosity. Near-wellbore reservoir stimulation is very common in such reservoirs with low-matrix porosity to enhance inter-connectivity between existing fractures. However, understanding the efficiency of such operations is usually critical for efficient production optimization especially when...

This paper focusses on successful deployment of TAML 4 systems in Kuwait field providing independent accessibility of both laterals during life of well for cleaning, stimulation, zonal isolation, selective production, data...

... oil initially offloading in surges and eventually liquid flow almost ceased. In order to conclude the true potential of the formation, acid stimulation was become inevitable. But acid stimulation of this vastly heterogeneous carbonate reservoir was a challenging and critical activity therefore...

... accuracy quick technique stimulation Introduction To recover hydrocarbon in economical levels from tight reservoirs, horizontal wellbore drilling along with multi stage hydraulic fracturing are primary strategies to unlock these reservoir's reserves. Identifying individual stage production...

... Abstract Smart Liners rely on the limited-entry principle where a number of small holes act to distribute acid along the un-cemented reservoir section. Over the past two years, this technique has become a key method for matrix-acid stimulation of ADNOC's carbonate reservoirs. The objective...

... Abstract Limited-entry liners (LEL) have predominantly been deployed in carbonate formations with only moderate variation in reservoir properties. In this work, a detailed numerical analysis was applied to investigate how the hole-spacing design can be tailored for effective stimulation...

... Abstract In carbonate stimulation and production enhancement, wormhole length is one of critical parameters to increase hydrocarbon recovery from a reservoir. It is well known that wormhole length is a function of the reaction kinetics, acid volume, acid concentration, and acid interstitial...

Natural fractures drive productivity in Clair Field producers, so no hydraulic fracturing stimulation was envisaged. Therefore, it is unsurprising that initial stimulation efforts on the Clair Field...

In addition, there is no doubt that in matrix stimulation the diversion and coverage of the treatment fluid plays a key role in driving the efficiency and final result of the operation. For this case study a customized acidizing blend combines primary and secondary reactions...

... Abstract Sludges formation during acid stimulation is a serious issue as it induces a damage that cannot be easily dissolved with most of treating chemicals. Recently, many wells experienced a drop in their potential following matrix acidizing treatment. Many factors could be attributed...
