The main function of traditional proppants is to provide and maintain conductive fractures
during well production where proppants should meet closure stress requirement and show …

The purpose of matrix treatments in carbonate reservoirs is to increase connectivity of a
formation with the wellbore in the entire zone of interest. Successful matrix treatments depend on …

To predict the length obtained from an acid fracturing treatment, acid fracturing models require
that diffusion coefficients values be included in the equations describing the transport of …

Hydrochloric acid is the most commonly used acid for carbonate acidizing due to its low cost
and high dissolving power. However, there are two major drawbacks associated with using …

A phenomenological model to simulate formation damage by dissolution/precipitation, ion
exchange, fines migration and clay swelling is presented. The model parameters are …

Rapidly increasing global energy demand and the limited global resources have renewed
interest in unconventional natural oil and gas. Economical hydrocarbon production from …

The cleanup of the filter-cakes formed by reservoir drilling fluids is a challenging task in long,
horizontal open-hole completions. Although various mechanical and/or chemical diversion …

Proppants are used to keep hydraulic fractures open, allowing for reservoir fluids to flow back
after external pressure is withdrawn. Proppants are carried by the hydraulic fracturing fluid …
