... included drilling a 3-kilometer-deep exploration well to collect subsurface data from the deep sedimentary and crystalline basement rock formations. These data will inform the design and specifications for creating an "enhanced geothermal system" comprised of a network of open fractures that will serve...

... Abstract Accurate determination of formation tops while drilling is a critical part of exploration geology workflow. Operational decisions on coring, wireline logging, casing and final well depth largely depend on it. One of the commonly used methods for picking formation tops while drilling...

... Abstract Electromagnetic telemetry (EMT) system uses a downhole source inserted near the drilling bit to send out real-time measurements via low frequency electromagnetic waves. A surface antenna picks up the transmitted signal by measuring the potential difference of two locations. Compared...

.... Real-time lithology determination while drilling can greatly optimise the drilling process and enhance geosteering. Using linear, non-linear, and ensemble machine learning algorithms, this study sought to automate the process of lithology classification while drilling. Also, the project sought...

... Abstract Logging-While-Drilling (LWD) formation testers have been successfully used for years in measuring formation pressure and estimating formation mobility. In terms of applications, among many others, this data has been useful for mud weight optimization while drilling, reservoir fluid...

... and permeability within a three-way-dip closure against a large growth fault. In 2018, Shell T&T embarked on Dolphin Extension Campaign project of 4 infill wells to increase gas production to backfill to Atlantic LNG export and domestic market. Upon completion of the drilling campaign, a Production Logging...

... It is important to note that well construction is a long process, and drilling itself takes 1/10 of the total time. The team noted that there is a need to improve efficiency both within each process and at the junction of related processes. Each major process consists of sub-processes and stages...

... Abstract Drilling wells in the remote northeastern part of India has always been a tremendous challenge owing to the subsurface complexity. This paper highlights the case of an exploratory well drilled in this region primarily targeting the main hydrocarbon bearing formations. The lithology...

... the methane measurement normalized by the Rate of Penetration. Assuming that for a particular formation drilled with constant bit size and constant mudflow rate the gas measurement can be normalized by ROP only. Gas components are continuously extracted from the drilling mud and monitored at the rig site...

... fluid GOR based on AMG data while drilling, before the wireline operation. This approach has clear advantages due to early access, low cost, and a continuous reservoir fluid GOR for all reservoir zones. In this paper, we release further study results to predict other fluid properties besides GOR, which...

... Abstract This paper will discuss the Managed Pressure Directional Drilling fit-for-purpose solution deployed to meet the drilling challenges faced in 5 consecutive wells drilled in South Texas, USA. This innovative solution integrates a state-of-art Rotary Steerable System (RSS) with Managed...

... Preventing accidents is one of the most effective ways to reduce non-productive time while drilling, and consequently, reduce the cost of well construction. Existing drilling support software is used to control equipment loads and its operation, to control hydraulics, to increase drilling...

... development is to the point where we are drilling laterals of 1,500 m (~5,000 ft) or more. Although portions of the lateral may be of such poor-quality rock that we do not attempt a completion, there will be portions where we do. Ideally with geosteering this will be 90 + % of the lateral. Further...

... and also thereservoirproperties of the rock themselves. As unconventional resource plays took off, many North American Basins have been carpeted with high quality 3D seismic that is routinely be exploited to reduce drilling risks, improve completion efficiency and high-grade acreage based on seismic...

... The industry efforts to improve the performance in the Brazilian pre-salt carbonates have been driven by a costly approach of trial and error in the ultra-deep-water drilling environment. In early 2012, an operator and service provider initiated a multidisciplinary research and development (R...

... Improvement of the reliability of the seismogeological model forecasts is required to minimize project risks. Taking into account the block structure of the fields, drilling of multiple exploration wells and accounting of the 3D seismic survey data are the classic solution of this task in Eastern...

.... Exploitation of producing wells confirms the assumption of oil moving along the sub-vertical zones of destruction and contributing to the primary target Upper Jurrasic-1 reservoir. Drilling of sidetracks from low oil rate and high water saturation wells in the areas with increased fracture network identified...

Field datasets, including the drilling operation parameters, formation type, and fluid mud characteristics, were collected from 385 wells drilled in Southern Iraq from different fields. The new models were...
