... productive high-rate gas wells within budget, which were put on stream in June 2021. The operations involved drilling the 5 ⅞″ reservoir sections under near-high-pressure/high-temperature (HP/HT) conditions in MPD mode, performing additional overbalanced logging runs, running sand screens, gravel packing...

... Abstract Core analysis, if conducted successfully, can provide accurate assessment of the original reservoir fluid properties, however, it is challenging to retrieve an uncontaminated core, due to mud components contaminating the fluids originally present in the reservoir. Due to invasion...

... Abstract Drilling for hydrocarbons in the extreme reservoir pressure and temperature remains one of the most challenging operation, especially related to drilling fluids. A combination of excellent teamwork and fluids technology proved to be the recipe for successfully drilling in these extreme...

... All the geothermal energy production discussed above, whether direct use or used for electricity production, is from naturally occurring hydrothermal reservoirs that are located in areas of tectonic or volcanic activity. Not unlike conventional oil and gas reservoirs, these hydrothermal...

... Abstract Combined challenges of drilling deep water matured reservoir hole sections with high levels of depletion present a risk for major downhole fluid loss events, well control hazards, and the resulting high remedial cost. Reduced fracture gradient, due to depletion and near-wellbore...

... drilling and completion fluids are preferred to avoid fluid incompatibility with injection fluid and reservoir fluids. Type and design of bridging material should be considered based on desired fluid and reservoir properties. If the required fluid density matches saturated sized salt systems, these fluids...

... approach encompasses casing design in shallow reservoir well with narrow margin between required formation integrity and fracture pressures, low kick tolerance, drilling in unstable formations, low temperature and pressures. Robust well design in shallow and weak formations is feasible with conventional...

... The A-36 A well was planned in the northern part of the Upper Fensfjord formation, which was identified as the most promising part of the Fensfjord reservoir. If successful, the pilot was planned to be completed as a producer and the A-36 B well to the separate Sognefjord Reservoir would...

... a wellbore strengthening approach to prevent these occurences and enable effective well construction. An engineered wellbore strengthening package was used to drill depleted sandstone reservoirs and enabling the client to drill the well, which was classically thought to require a Managed Drilling Pressure...

... Abstract A drilling fluid designed for drilling long horizontal wells in extremely depleted chalk reservoirs within the limitations of a narrow mud weight window, high overbalance, high solids contamination and static periods was successfully implemented when drilling a water injection well...

... with very good reservoir quality. The field comprises a main structure and some additional segments. The reservoir depth is 1,700 metres, and there is full communication in the reservoir. Oil recovery is maintained by gas injection and drilling of new wells, including sidetracks from existing producers...

..., in Brazil, drilled two exploratory wells applying MPD and targeting Vaca Muerta shale oil & gas play. High-pressure zones characterized the drilling scenario, reaching, usually, pore pressures higher than 18 lbm/gal in unconventional reservoirs, composed of tight sand and shale. The use of MPD in both...
