It also explores the potential of new, synergistic strategies and work processes planned for stimulation of the upper Tuba field. upstream oil & gas real...

... of the wells in NKJG fields are a mixture of vertical, deviated and horizontal wells. A 5" or 4-1/2" liner is run in the primary target in Marrat and a 7-5/8" liner is installed against the secondary target in the Najmah sequence. The reservoirs are typically acidized, there is an hydraulic proppant fracture...

...Corrosion Tests Gelled acids have been utilized for a long time for carbonate stimulation. These high-viscosity fluids utilize a crosslinkable polymer for increasing the acid viscosity to achieve deep reservoir penetration and uniform stimulation ( Rabie et. al. 2011 ; Gomaa et al. 2010...

... Vitamin C has 4 stereoisomers which are L-ascorbic acid, D-ascorbic acid, L-isoascorbic acid, and D-isoascorbic acid. Isoascorbic acid by definition has a D chirality on the carbon in its hydroxyl chain, using the L and D in its name is in reference to the chirality of the carbon...

... to these challenges was achieved by implementing one of the first trials in Kuwait for a fully energized acid fracturing technique using enhanced stimulation fluids. The main challenges of stimulation in this depleted reservoir are the need for extended post-fracturing formation cleanup and the nitrogen lifting...

... primary well completion using energized acid fracturing technology over regular stimulation. During fracturing, the acid system will form highly etched channels in the formation. Most of the fluid will flow into the path of least resistance leaving large portions of the formation untreated. As a result...

... Abstract In high-temperature carbonate producers, conventional hydrochloric (HCl) acid systems have been ineffective at delivering sustainable production improvement due to their kinetics. Retarded acids are deemed necessary to control the reaction and create effective wormholes. This scenario...

... for sustainable flow. Hence it became important to not only rely on plain acid systems for production gain, but to also include more sophisticated acid stimulation systems that can provide improved results in more challenging environments where plain acid may be found lacking. These results were recently achieved...

However, under such a high differential pressure environment, the use of acid may induce losses in the so called "thief zones", causing worse problems. The standard release procedure started by working the string within the tensile...

The development in offshore environments requires proper planning, execution, and monitoring to achieve the desired results and, of course, profitability. The matrix acidizing method was chosen to stimulate all wells of this campaign (2 producers...

... Lactic acid has started to gain more attention lately due to its dissociation constant that is comparable to formic acid, that is shown in Table 2 . Additionally, lactic acid is an environmentally friendly product and is less corrosive comparing to HCl ( Nasr-El-Din et al. 2007 , 2009...
