..., considering the high risk of tool stuck, the limited borehole access and/or the very high operational costs. In that respect, intrawell chemical tracers (ICT) represent a valid and relatively cheap wireless monitoring solution alternative to PL. This paper deals with the complete modeling of tracer...

... ABSTRACT Downhole well surveillance is considered, during an asset exploitation, a mainstay for the proper characterization of well completions and reservoir behavior. For these activities, specific tools have been developed to address wellbore integrity issues (e.g., sonic, ultrasonic...

... ABSTRACT As the oil and gas industry continues to mature, wells are drilled in increasingly challenging environments, often putting at risk the formation evaluation program in an open hole environment. Even if the well is accessible, cost and risk of a complete multi-run OH formation...

..., in fractures, and flow geometry inside the smart completions. Platform generates 3-D distributions pressure and temperature along the horizontal wellbore, providing quantitative flow analysis in liner, annulus and sandface, as well as along each fracture. The model utilizes a 3-D grid that covers the wellbore...

... ABSTRACT Identifying the oil and gas zones for completion is a long-lasting challenge for production wells in depleted reservoirs. This is not because the conventional logging while drilling tools are not working but due to the increased complexity of the reservoir fluids under depleted...

... ABSTRACT The reservoir under discussion is located between Saudi Arabia and Kuwait. Designing the right completions strategy to minimize water cut has been challenging in the target reservoir. One of the biggest challenges relates to variable hydrocarbon mobility and understanding...

... as 2 meters, maximizing the wellbore exposure to the reservoir. The philosophy of engineered completions is to place perf clusters in like rock so that all perf clusters fracture simultaneously, and not have one cluster dominate over others. Petrophysical data are needed as a foundation for engineered...

... heavily on modeling of tool responses for the given completions and fluid types present in the system. This modeling is usually achieved through nuclear Monte Carlo simulations and involves long computing times, significant computer resources, and human intervention. However, despite the time and cost...

This paper presents a novel application of DSWI as a post-fracture diagnostic technology to characterize the mid-field fracture stimulation...

... ABSTRACT Reservoir quality and completion efficiency are key factors that impact well performance. The relationship becomes more complex for the case of Cased Hole Gravel-Pack and Frac-Pack completions. Most of the time, completion quality and reservoir description were treated in isolation...

... in the nano-darcy range, low porosities are common, and conventional petrophysical logs are inadequate for prolific zone identification and completion selection. This discussion focuses on the development of a criterion to identify optimal lateral window and effective frac zones for completion, maximizing...

... Abstract Formation evaluation through casing is becoming more prevalent with the availability of multidetector pulsed-neutron tools (MDPNTs) from all major service companies. Monte Carlo modeling is important for not only optimizing nuclear tool designs but also for providing completion...
