Drilling fluid loss always occurs in fracture-porosity reservoirs and it causes severe problems. To reduce prevent lost circulation, is important to get know the cause characteristic of drilling loss. According approach reservoir simulation well test analysis, a new model for presented. Multi fractures formation seepage between fracture rock matrix have been considered model. The governing equa...

DURING the loss or gain of edema the composition of the extracellular fluid remains remarkably constant despite the large ehanges in volume. A number of studies have indicated that the renal excretion of body water and electrolytes does not completely aceount for this constancy. In studies of edema loss, electrolytes and water were not lost in the same proportions that exist in extraeellular fl...
