... of a well. The casing wear shall be managed from both design and operational phases to ensure well integrity not affected by casing wear. Casing wear is the mechanical work of friction between the contacting areas of drill string and inner wall of casing. There are different casing wear mechanism and wear...

... conductor depth is 250 ft. In Mutiara and Pamaguan Fields, conductor piling limited to 250 blow/ft can reach an average depth of 50 ft below ground level. It is either additional surface casing must be run or new method must be used. One of the methods that might potentially be used is auger drilling which...

... as pressure preservation and dissipation processes through geologic time. This improved understanding provides invaluable insight into the different drilling challenges and the strategy to mitigate or minimize pore pressure related problems. Once the pore pressure model is established, the in-situ stress...

... in this model. The results show that drilling parallel to the maximum horizontal stress direction neither achieves the best stability of the borehole nor maximizes the permeability ratio. Drilling along the minimum horizontal stress direction would maximize the permeability ratio, but it has the worst...

... Abstract This paper presents a comprehensive laboratory and field study, discussing the development, formulation, and application of a wellbore strengthening mechanism, for strengthening weak formations while drilling in a deepwater high-pressure/high-temperature (HP/HT) well environment...

... Abstract The objective of the study is to build a robust Recurrent Neural Network system using Long-Short-Term-Memory (LSTM) to predict future vibrations during drilling operations. This provides a reliable solution to the complex problem of modeling several forms of vibrations encountered...

... Abstract Drilling long horizontal development wells in a conglomerate reservoir with strong heterogeneity has been challenging in the Junggar Basin, onshore China. To develop the fields economically, rapid and safe drilling with minimal non-productive time (NPT) is required. However, various...

... Abstract The Ordovician fractured carbonate reservoir in the Shunbei field is buried ~7300m below ground level and has presented great challenges for the drilling of extra deep, deviated development wells. Borehole instability-related drilling problems including pipe stuck, pack-off, and mud...

... Abstract Sampling While Drilling has been successful in recent times covering numerous applications including difficult boreholes, horizontal wells, influencing drill stem test plans, cost savings in marginal fields, high sample volume collection, aid in quantifying non-hydrocarbon content...

... Abstract This paper describes the application of using new 3D shape PDC cutters in XX development wells in offshore Sarawak. Based on historical drilling data from offset wells around the XX Field, multiple bit trips were required on each section from 17-1/2" until 8-1/2" holes. Various bit...

... Abstract The paper is sharing experience on using the cross-well pressure pulse-code testing (PCT) to locate the remaining reserves for the waterflood infill drilling. R Field is a very mature giant field in Volgo-Ural region of Russia and has been under production for more than 70 years. One...

... Abstract An operator recently drilled and completed an onshore well in South Sumatra by intentionally leaving 3-1/2 in. drill pipe in the hole, to be used as the lower completion string. This paper documents the design and execution of this unique drill pipe completion idea, overcoming...

... Abstract Operators in the current volatile oil and gas industry must optimise drilling performance and minimize well cost. Various drilling tools and methods have been implemented over the years to improve drilling efficiency and to reduce the non-productive time (NPT) while drilling through...

... Abstract Shallow water flow is one of the geological disasters faced by deep water drilling operations. The common way to predict shallow water flow is applying qualitative prediction of seismic profiles and the accuracy is low. This paper proposes a new approach based on simulation experiment...

... and learn from them. Paper explains the specifics of public and corporate sessions and brings few case studies on both. The training facility is based on PolyPlan simulator which has a very simplistic user-friendly webinterface which allows petroleum engineers perform typical routine activities (drilling...

Each subsidiary requires many approaches to restrain high natural declined rate related to drilling, workover, and well services activities. Consequently, Pertamina as the new Operator had to immediately conduct...

... production comes from fractured igneous (granite, granodiorite) and metamorphic (meta conglomerate, quartzite, phyllite and marble) rocks of the pre-Tertiary basement. To date, eight wells have been drilled during the exploration and development program. The most recent development well was the X-8, which...

Abstract The paper will discuss the advancement of recent technology high definition resistivity imager convey with drilling assembly (Logging While Drilling) to quantify fracture geometry and secondary porosity (vuggs) in highly fractured carbonate. Oligo- Miocene carbonate Kujung formation...

... techniques, the Lower Longmaxi Formation has been successfully produced. To further increase the hydraulic fracturing efficiency, brittleness evaluation and perforation optimization are necessary. A total of 100 bags of drill cuttings from different depths in three shale gas wells were initially collected...
