... characteristics different from conventional reservoirs. Successful production of this type of reservoir depends on two aspects, its hydrocarbon generation potential and the ease of extraction. Therefore, characterizing and determining the natural fracture zones that will be connected by the drill bit...

... Abstract The geomechanical model for mud density optimization is essential to guarantee drilling success. This will allow to avoid problems such as: wellbore collapse, influx, induced fractures, pipe sticks, among other aspects that contribute on cost increasing and NPT. Normally, conventional...

... the degree of easiness to which a formation can be fractured; the most fracable intervals are usually spot that require less energy to fracture. Brittlennes and fracability indexes have been incorporated by the industry for the optimization of the completion, although in some cases the efficiency...

... for the estimation of mud weight windows, critically stressed natural fractures analysis and optimal well trajectories. Furthermore, extensive triaxial test results on rocks has been implemented in the geomechanical models. Finally, real-time wellbore stability monitoring has been implemented to reduce non...

... Abstract Hydraulic fracture stimulation is the single most important technology which unlocks vast unconventional resources. Hydraulic fracture design requires a good knowledge of subsurface stress regime, especially the anisotropic minimum in-situ stress profile to determine landing zone...

... and permeability by managing rock dilation and fracturing behavior. As a result, new areas are created for injected stimulants to contact the heavy oil, speeding up viscosity reduction and improving oil production. Additionally, the same mechanism can break down the permeability barriers in the reservoir...

... SUMMARY: This work presents a methodology for mud losses mechanism evaluation based on geomechanics of fractures. Several and catastrophic mud losses events are continuously experienced during drilling the 8½̈section in Castilla Field in Llanos basin, Colombia. Technologies like Manage...

... reservoirs. Additionally, extensive tri-axial and total carbon organic (TOC) tests in shales have been included in the study to calibrate the mechanical properties and TOC obtained from the electrical logs. The concept of critically stressed fractures has been included in the analysis of this geomechanical...
