... Abstract A comprehensive study of about 200 production stimulation treatments in carbonate and sandstone formations of Karabulak and Aryskum brownfields was performed. The stimulation methods analyzed in this study are propped fracturing, acid fracturing, matrix acidizing with different fluids...

... behavior can be explained by large fracture corridors, which display high contrast in permeability to surrounding matrix rock, thus leading to different boundary effects at late times of the well test data. drillstem/well testing reservoir simulation fracture characterization drillstem testing...

..., middle and bottom zones would be a reasonable option. Abstract Tengiz field is a super-giant carbonate reservoir located in the Western Kazakhstan. The carbonate matrix consists of almost pure calcite, which makes it very attractive for acid stimulation. Over the years matrix acid stimulation has...

... (CT acid wash, bullhead acid wash, high rate matrix, and acid fracturing) were assessed against the reservoir/petrophysical parameters, productivity index and percentage contribution of zones from production log. Productivity and Flow distribution improvement There is a long history...

... Abstract One of the main factors affecting the type of stimulation treatment in carbonates is reservoir properties. Acid fracturing effectiveness, in terms of economics and production increase, could be potentially more beneficial than matrix acidizing in case of low permeability...

...Review on modeling of the carbonate rock dissolution Matrix acidizing is one of the effective methods to restore the near-wellbore zone properties of carbonate formations. During matrix acidizing acid is pumped into the formation through the wellbore at a certain rate and reacts...

... Abstract Recently Mittermeir (2014) introduced a new material balance (MB) method applicable to naturally fractured dual porosity reservoirs which correctly considers the matrix-fracture fluid transfer too. The MB model is built by two columns, representing the matrix and the fracture...

... Abstract This study presents a process to investigate mass transfer between fracture and matrix in naturally fractured reservoirs. The study has three parts: (1) the effect of imbibition by capillary pressure Pc in matrix, (2) mass transfer between fracture and matrix through k*σ, and gravity...
