New solutions for wells with finite-conductivity fractures including wellbore storage and fracture-face skin Conference Paper uri icon

abstract

  • This paper presents new solutions for wells with finite-conductivity fractures including wellbore storage and fracture-face skin damage. An infinite-conductivity fracture is included as a limiting case. The new solutions are obtained numerically by modeling a well with an elliptical finite-conductivity fracture in an elliptically composite reservoir. The new solutions are as accurate as published analytical solutions, which are available only for limiting cases. In addition, this study finds and confirms that an 'apparent' skin results in a well with a finite-conductivity fracture and fracture-face skin; this 'apparent' skin is larger than the true fracture-face skin. The new solutions presented in this paper can be used to analyze production and welltest data for wells with finite-conductivity fractures including wellbore storage and fracture-face skin. Examples are provided.
