... strategy. Global successful cases and modeling results pushed the decision team to use an ultradeep reservoir mapping service (UDRMS) to cost-effectively optimize this redevelopment efficiency. With the depth-of-investigation (DOI) up to 30 m from the borehole, UDRMS could use the resistivity inversion...

... of intermittent pumping interval lacks reasonable theoretical basis and the control efficiency is relatively low. Therefore, an integrated intelligent intermittent pumping device combining edge optimization analytic and edge control is developed. A closed-loop integrated device containing real-time data...

... efficiency and performance, yielding more useful power output thus reducing the GHG emissions. The less fuel burned per unit power derived, the lower the GHG emissions intensity. To optimize the performance, the operating data are scrutinized systematically to permutate the actual power, efficiency, fuel gas...

..., the industry has focused on two core tenants of value: Increased safety and efficiency Personnel reduction For widespread adoption of an enhanced digital solution, the technology must not only provide quantifiable value in at least one of the core tenants, but also must repeatably demonstrate...

.... This paper will introduce a drillpipe conveyed casing and cement evaluation tool that can be deployed in parallel with other runs in the well to improve the efficiency of operations whilst also increasing the frequency of times that this data can be acquired. Through case history we will demonstrate how...

... Below are some of the factors that historically have affected perforating efficiency in Thailand: In this system, each gun has a compact expendable docking module - a modularized initiator equipped with a radio frequency safe detonator and an addressable switch. This system can be used...

... clearly delineated. Accordingly, the quantitative well placement operations were efficiently executed to distribute the actual smooth trajectory connecting multiple sandstone bodies with the less risk, as well as with maximum standoff to the tilted OWC. The quantitative results from the inversion-derived...

... and selection of this project. The summary of the screening shows that Adsorption technology is more attractive than the others because it provides the highest As removal efficiency of up to 90%. Apart from adsorption, other technologies can remove arsenic 10% with filtration and centrifugation being...

... −3 level; 2) decrease the oil-water contact angle from 55° to 9 °; 3) reduce the crude oil viscosity from 259 cp to 132.8 cp, with a viscosity reduction rate of 48.7%; 4) improve the oil washing efficiency of oil sand to as high as 79.1%; and 5) improve the oil recovery rate of core plugs by 25%∼46...

..., resulting to higher efficiency of injected heat. Thermo-gel treatment was carried out for the rest three wells in the second cycle. Around each of the three thermal injection wells, there were 2∼3 wells that could have fluid breakthrough and only one surrounding well happened. Compared with the first three...

... Abstract The efficiency of hydrogen sulfide scavengers directly injected into gas streams is often compromised by short contact times due to space limitations on offshore assets. The use of static mixers is often employed to increase the efficiency of gas-liquid mixing. The performance of two...

However, currently used chemical inhibitors are costly and environmentally harmful if a spillage occurs. Therefore, the use of biodegradable or environmently...

..., the efficiency can be deteriorated when the LSPF process is adopted to carbonate reservoirs with highly acidic or high-salinity formation water. In order to maximize the LSPF efficiency, properties of the injection fluid need to be properly designed in terms of salinity, ion composition, and ion concentration...

... the supercritical CO 2 and formation water, CO 2 migrates upwards to the atmosphere. The risk of this CO 2 migration can be prevented by different trapping mechanisms (e.g. structural trapping, capillary trapping, dissolution trapping, and mineral trapping). The trapping efficiency of these trapping mechanisms...
