.... Isolating target zones with a coiled tubing (CT) deployed inflatable packer enabled combining the suppression and stimulation treatments in a single intervention. Each treatment can then be tailored by leveraging real-time CT downhole measurements, and injection profiles can be balanced by adjusting...

...Real-Time Fiber-Optic Coiled Tubing Technology Abstract Historically, the preferred method for restoring production on oil producers in a mature field in South Europe (Field A) was bullheading a matrix acid stimulation treatment. Even if successfully implemented, bullheading treatments...

Based on the results obtained from the laboratory tests, a stimulation treatment with Synthetic Acid was carried out in the oil producing well in the BKS formation, achieving immediate increases in their operating conditions (temperature, pressure in the downstream pipe...

... tubing (CT) interventions are required to successfully enter and identify each lateral, as well as to remove formation damage by pumping the matrix stimulation treatment across entire laterals. During such CT interventions, laterals are accessed thanks to a hydraulically operated lateral identification...

...Fracture Acidizing Stimulation Design The drilling, completion, reservoir, lithology, and geomechanics information presented previously was used to design an improved selective acid fracture stimulation treatment for the well. Considering the alignment of the wellbore, the maximum stress...

... and dipole sonic data were acquired in the horizontal well, and both longitudinal and transverse induced fractures were identified. Those data were used to selectively place hydraulic fracturing stages. Diagnostic injection tests on each stimulation treatment confirmed low fracture initiation pressures...

... obtained via a conventional production logging tool prior to the treatment. When SWD wells show a decrease in injectivity, the operator’s preference is to conduct stimulation treatments or reperforate target intervals before deciding on a costly workover operation. The decision to intervene is often made...

By applying the estimated EURs in the newly developed model, the authors analyzed the economics of more than 3900 shale oil wells in Eagle Ford and Bakken. Results show that the mean breakeven oil prices in Eagle Ford and Bakken are, respectively, $69/bbl...
