dc.description.abstract This project is a research into the effect of gas condensate damage in hydraulically fractured wells . It is the result of a problem encountered in producing a low permeability formation from a well in South Texas owned by the El Paso Production Company . The well was producing from a gas condensate reservoir . Questions were raised about whether flowing bottomhole pressure below dewpoint would be appropriate . Condensate damage in the hydraulic fracture was expected to be of significant effect . In the most recent work done by Adedeji Ayoola Adeyeye , this subject was studied when the effects of reservoir depletion were minimized by introduction of an injector well with fluid composition the same as the original reservoir fluid . He also used an infinite conductivity hydraulic fracture along with a linear model as an adequate analogy . He concluded that the skin due to liquid build -up is not enough to prevent lower flowing bottomhole pressures from producing more gas . This current study investigated the condensate damage at the face of the hydraulic fracture in transient and boundary dominated periods when the effects of reservoir depletion are taken into account . As a first step , simulation of liquid flow into the fracture was performed using a 2D 1 -phase simulator in order to help us to better understand the results of gas condensate simulation . Then during the research , gas condensate models with various gas compositions were simulated using a commercial simulator (CMG ) . The results of this research are a step forward in helping to improve the management of gas condensate reservoirs by understanding the mechanics of liquid build -up . It also provides methodology for quantifying the condensate damage that impairs linear flow of gas into the hydraulic fracture . en_US
