Paper Number: SPE-174171-MS
... intervals, although the execution of the stimulation programme brought significant challenges. This paper introduces the Breagh Field, discusses the reasons behind the change in completion design to include hydraulic fracture stimulation, considers the challenges associated with fracture placement in high...

Paper Number: SPE-174247-MS
... Abstract Effective and uniform placement of treatment fluid across multiple zones can be challenging. This is particularly true during stimulation or remedial treatments for formation sand control, as well as during water shutoff treatments. Such challenges can be greatly enhanced when a long...

... as a function of the mineral content. The optimum concentration of the HF was proven to adopt an inverse relationship with the mineral concentration. The proposed relationship can be used to determine the optimum acid concentration required for sandstone stimulation. Upstream Oil & Gas optimum...

... the fracturing pressure to keep coal cleats and shale fractures open during water-gas production. Graded proppant injection in CBM and SG reservoirs can: stimulate a stress sensitive cleat system below the fracturing pressure; enhance fracturing treatment by invading cleats, lowering fluid leak-off...

Paper Number: SPE-174234-MS
... Abstract Historically, leak-off analyses of stimulation fluids have been performed using in-house laboratory procedures. The lack of industry standard procedures to perform leak-off and wall building coefficient analyses of stimulation fluids has introduced inconsistency in both results...

... Abstract The stimulation history in offshore Brazil is undergoing into a deep transformation. The requirements of technology, before focused on sandstone reservoirs demand, are being expanded by the need for techniques to stimulate carbonate reservoirs, specially the pre-salt carbonates...

..., hydrajetting fracture stimulation on three wells. Although the field is non-conventional, so far, it has been developed conventionally. A large amount of the original oil in place still remains in the reservoir. To make the redevelopment project viable, a step change in stimulation techniques...

... problem in wells in Ecuador. The main challenge is to increase oil production through stimulation in wells with high water cut and a strong aquifer, without increasing the water cut. A treatment was proposed that would remove the damage in the intervals producing oil and "good" water without stimulating...

Paper Number: SPE-144051-MS
... Abstract Acid stimulation for damage removal is performed when a well is expected to produce satisfactorily when the skin is approximately equal to one. Blindly flowing acid into the well is the easiest thing to do and is commonly performed when the exposure length of the well is relatively...
