... The subject well W-1 was spudded and initial drilling was smooth without major complications and the shallower sections posed no issues during the first phase of drilling and casing installation. This prelude, however, painted a picture in sharp contrast to the challenges that cropped up during...

... project takes about two years. Taking into account the fact that the main large traps of oil and gases were already drilled long ago and only small and heterogeneous traps remained, it is necessary to look for opportunities to reduce the implementation time, increase its speed, efficiency, safety...

...Abstract Abstract Objectives/Scope The acquisition of mud gas data for well control and gathering of geological information is a common practice in oil and gas drilling. However, these data are scarcely used for reservoir evaluation as they are presumably considered as unreliable and non...

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...

... 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 The paper provides a technical overview of an operator's Real-Time Drilling (RTD) ecosystem currently developed and deployed to all US Onshore and Deepwater Gulf of Mexico rigs. It also shares best practices with the industry through the journey of building the RTD solution: first...

.... This paper presents a workflow that can be used to build a decision tree for an unconventional play in the appraisal phase of development, given ranges of uncertainty in production profiles and drilling and completion costs. In applying this workflow, managers will better understand both the drivers...

... illustrates the risks of drilling wells without a good understanding of structure. If you are drilling with tight target thresholds, small dip changes combined with bed dip converging bit inclinationscan hurt you quickly; i.e. a 94 degree bed dip combined with a 92 degree bit inclination would bring you down...

... Abstract The Gulf of Mexico, and more precisely the Wilcox trend, has long been considered as challenging area for developing profitable hydrocarbon fields. In fact, the safe drilling of deep offshore wells needs to take into account the geological and geomechanical complexities, generated...

... Abstract After findings were made in the pre-salt province that represented a major discovery for the oil industry, drilling activity in Brazil has been focused primarily on economically viable ways to develop these reserves. The pre-salt cluster is a geological formation that consists...
