Abstract: Stimulation methods can be used in production, discovery and appraisal wells. The purpose of stimulation is to restore or enhance the delivery of hydrocarbons to the wellbore. Wellbore will halt the production of the hydrocarbons after perforating because permeability has been decreased and wellbore region has been damaged due to specific reason. In a general case, it can be called as formation damage. Well tests is applied to measure production rates from a well and estimate the stimulation methods compatibility. Stimulation treatments has to be done for the cased hole. If we apply stimulation methods into the open hole open, borehole collapse and packer leaks will occur. Reservoir stimulation accomplishes this primarily by restoring, improving, increasing or otherwise modifying the permeability of the target formation. Types of stimulations which are utilized to maximize well’s productivity are below: • Matrix acidizing: İn this method, acid is pumped into wellbore but this is not high pressure acid to create channels as HF treatment fluid.. This acid helps to dissolve the rock around the well bore which have blocked the perforations. These acid enlarges the channels. • Hydraulic fracturing: This stimulation method imvolves pumping high pressure mixtures which contribuites to create high permeability channels. • Acid fracturing: This is used to form high conductivity channels in near wellbore area which are having high permeability channels in the carbonate rocks In this thesis, the key aspects of the hydraulic fracturing and matrix acidizing, such as their mechanics, geometry and design are reviewed. Predominantly, the key challenges and motivation behind the process are mentioned, and the principal objectives of the following experiments have been identified. The theoretical knowledge on the hydraulic fracturing and matrix acidizing, its impact on maintaining of fractures, the mechanics of fractures, related industry challenges, several types of stimulations and innovations are talked over in one of the chapters.
