Enhanced oil recovery methods are used to recover the percents of oil, which are not naturally recoverable from reservoirs. Water injection, as a secondary recovery, is used to maintain the pressure in water-drive reservoirs. An important point for h

Scale formation in surface and subsurface oil and gas production equipment has been recognized to be one of the major operational problems. It has also been recognized as one of the major causes of formation damage either in injection or producing we

Production rates in unconventional plays can decline dramatically, up to 70% in the first year. Refracturing—by today's understanding—is a remedial production operation often done because original fracturing failed to contribute any significant a

Most naturally fractured reservoir rocks are mixed to oil wet and do not imbibe the injected water, which translates into low-efficiency waterflood recovery. To enhance the spontaneous imbibition process, a low concentration of surfactants is dissolv

Spontaneous imbibition is of special importance in oil recovery from fractured reservoirs. Laboratory measurements of volume of liquid imbibed versus time are often used in the prediction of oil recovery. Laboratory results of oil recovery through sp

Stuck pipe is one of the main problems in drilling oil and gas reservoirs. It usually occurs in high-pressure wells and leads to tremendous delays and costs in Iran every year. Even if different techniques and guidelines have been developed to reduce

A new solution for determining the amount of mud loss during drilling operation in a fractured reservoir having a regular two- or three-dimensional radial fractured network with the novel inclusion of a convective transport of filtrate in the matrix

Borehole ballooning-breathing is the term used to describe reversible mud losses and gains during drilling operations. In naturally fractured reservoirs borehole ballooning-breathing caused by opening/closing of natural fractures is the major mechani

Most of the drilled wells are conducted on acidizing in order to eliminate the permeability reduction due to mud filtration. This type of formation damage is more sever in naturally fractured wells due to the high conductivity of fracture. If the rad
