... Abstract The using of horizontal wells is an effective exploitation way for naturally fractured reservoirs. In accordance with horizontal wells in a naturally fractured volcanic reservoir, the characteristics of damages from drilling, completion and natural blockages are discussed and the aim...

... Abstract A mathematical model is developed in order to evaluate the productivity ofmultilateral completions. The model may also be used to understand and discernthe pressure behaviour of multilateral completions. The ability to incorporatethe location of each lateral rigorously is the unique...

... Abstract During drilling and completion the primary mechanisms of near-wellbore formation damage include pore-throat constriction, water blocking, plugging with drill solids and mud products, and loading of the reservoir with drilling or completion fluids. Among these mechanisms, some...
