Paper Number: SPE-70040-MS
... to microporosity. Clean bearing sandstone has high resistivity, but when this rock contains clay, or heavy minerals such as pyrite, the resistivity can become low. Pyrite shows a good electrical conductivity, that is usually comparable to or even higher than the conductivity of formation water, and can therefore...

.... The results indicate a 65% improvement in early, six-month, oil recovery and improved effective stimulations versus prior development projects. These results are primarily due to increasing the fracture conductivity through more effective proppant placement. Descriptions of the fracture treatment designs...

... Enhancement Efforts The earliest wells were open hole completed with a small cleanup "hydrafrac". A survey of 781 wells conducted in 1952 indicated that 92% of the wells in the survey were openhole completed, with the majority of the treatments consisted of 1500 gal of fluid or less3 As operators gained...
