... randomly sampled realizations of our reservoir model, well location, type and control sequences of a drilling plan. From all the possible decisions involved in a FDP, we focus here only on finding optimal adaptive well drilling schedules (locations of vertical wells and well types). The RL agent learns...

... Abstract We developed and investigated the effectiveness of new multifunctional foaming agents (MFAs) for production enhancement in oil wells with gas lift or high gas-oil ratio, high water cuts (>30%), and very high conditions of temperature (180°C), hardness (180,000 ppm), and salinity...

... such as HCl, formic, citric, and acetic acids, as well as the barite has low solubility in chelating agent such as Ethylene Diamine Tetra Acetic Acid (EDTA). The present study introduces a new formulation to dissolve the barite filter cake using converters and catalysts. Barite can be converted to barium...

... chelating agent that has the abilities of a cross-linker, breaker, biocide, clay stabilizer, replacing those constituents in one simple fluid, GLDA is also a low IFT fluid which will reduce the IFT eliminating the water blockage problems due to the capillarity effect in tight reservoirs. It is also stable...

... of replacing several different cement additives. This slowly-hydrating, hydrophilic biopolymer is capable of performing as a fluid loss agent, suspending agent, free water control agent, and extender for use in wells up to 225°F and in some conditions up to 250 °F. The single, new cement additive effectively...

Another option is to introduce a bridging agent to minimize fluid losses to the reservoir by enabling higher bottomhole...

... Abstract Reliable detection of propping agents in fractures has been a challenge for the petroleum industry. Researchers are currently investigating the application of nanoparticles as contrast agents for reservoir characterization and advanced reservoir surveillance. This paper demonstrates...

The use of a novel low corrosive chelating agent, glutamic acid N, N-diacetic acid (GLDA), instead of hydrochloric acid, was evaluated to remove calcium carbonate and iron scale depositions found in Well A's downhole electrical...

.... The strong organic acid surfactant, dodecyl benzene sulfonic acid (DBSA), has been shown to completely dissolve asphaltenes via acid-base chemistry reactions at heteroatomic sites on the asphaltene molecules. We investigate the use of DBSA as an efficient removal agent, injecting it in a mixture of petroleum...
