The wide range in porosity ard permeability is primarily a result of textural properties due to the depositioral enviromment. Diagenesis has slightly reduced the reservoir quality by intergrara~lar cementation stud clay mineralization. Tectonimm has f~rther degraded the reservoir due to low-permeability gouge-filled fractures.

A dual porosity system describes fluids present in fractures and matrix blocks. Fracture flow equations and matrix/fractu~re flow are solved. Example problems are presented to demonstrate the use of the model : gas and water injection.

m88-198 HBmlrologic ard geologic investigations were carried out to attcly the flow systems in the Car~on sedimentary rocks 8x~ to assess the effects of fracturing on grourdwater recharge. It is concluded that factors responsible for efficient capture of recharge are: increased rock fract~img due to basement faulting, steeply dipping rocks which allow gravity entry of water along fracturesj dissolution of sandatones in the recharge area I and thick deposits of alluvium often entrenched in the fractt~re zomes. 836077 N00RDBERGUM EFFECNf AND CKARACTERIZATION OF A~UITARDS AT THE RIO MAIOR MINING PROJECT Rodrigltez, J D Ground Water, V21, N2, March-April 1983, P200-207 The planned exploitation of the Rio Maior lignite deposits which overlie a leaky sand aquifer will require an extensive dewatering program.
