Electrokinetics Technology to Improve Acidizing of Carbonate Reservoir Rocks

Chemical Induced Wettability Alteration of Carbonate Reservoir Rocks

An Impressive Impact on Well Productivity by Hydrochloric Acidizing of Vuggy Carbonate Reservoir: A Case Study

Hydrochloric acidizing is a routine operation in oil fields to reduce the mechanical skin. In this paper, practical acidizing in a typical carbonate oil reservoir located in the southwest of Iran is practiced, which shows an unexpected improvement after acidizing. To understand the acidizing effect on reservoir rock, the formation rock is analyzed on different scales. An acidizing laboratory te...

Numerical modeling of hydraulic fracturing in carbonate rocks of Bangestan reservoir

Hydraulic fracturing is used in the oil industry in order to increase the index of production and processing in the wells whose efficiencies have been dropped due to a long-term harvest or the rocks around the wells are of low permeability. Since the hydraulic fracturing operation is costly, it is of special importance to the project managers to determine the pressure required for hydraulic fra...

AN EXPERIMENTAL INVESTIGATION OF GRAVITY DRAINAGE DURING IMMISCIBLE GAS INJECTION IN CARBONATE ROCKS UNDER RESERVOIR CONDITIONS

Gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. It occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. Oil phase will form films which are produced under gravity forces (film flow). Many gas injection experiments have been done on laboratory scales with d...

Title: Application of Reservoir Characterization and Advanced Technology to Improve Recovery and Economics in a Lower Quality Shallow Shelf Carbonate Reservoir

The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluati...
