AbstractThis paper presents a numerical modelling of propellant gas fracturing processes, which may be used as a quantitative tool for controlling and optimizing the pressure pulses generated by propellant combustion under the down-hole conditions. The model consists of propellant combustion, well fluid compression and movement, fluid drainage through perforations, fracture extention and flow in fractures. By using a proper algorithm, the pressure profile is calculated step by step. The paper also derives the formulae for estimating the productivity increase achieved by multiple fractures. The models have been verified by comparing with lab experiment and field measurements. Besides, the paper also discusses the method of estimating the productivity increase made by the propellant gas fracturing and the main factors of influence. Based on the numerical model, the paper also discusses the method for designing propellant gas fracturing, including a parametric sensitivity study of propellant charge, well completion, perforation and formation properties, etc.

AbstractThe primary objective in the design of a perforating program is to remove or minimize any impedance to the desired fluid movement from the reservoir to the cased wellbore. The possible damage that could occur from drilling-fluid contacting the formation is one of the significant problems that must be addressed in selecting the perforation technique. As drilling fluid enters the formation, it can deposit solid matter, cause clay swelling, and induce chemical precipitation, creating a damaged zone area around the wellbore. All of these resulting phenomena reduce the size of the pores available for fluid flow. In addition to the induced drilling fluid damage, the radial displacement of formation materials during the perforating event causes crushing and compacting of the area that immediately surrounds the perforation (better known as the crushed zone area), which will subsequently result in a reduced permeability envelope around the perforating tunnels.Perforating the well in an underbalanced condition using super deep penetrating "premium" charges has proven to be an effective technique in removing near wellbore damage, as it allows the formation pressure to remove the damaged rock instantly. However, if the formation pressure is too low to move the damaged rock, permeability at the face of the perforation can be greatly reduced. In many wells, the damage can be so severe that only 25 percent of the perforations will produce. This paper reviews the successful application of a combined propellant and perforating technique in depleted, highly laminated sand reservoirs. In the case histories discussed, applying this technique resulted in stimulated wellbore conditions that improved flow efficiency. The results from the pressure transient analysis are included and will verify the attained productivity improvements.The paper also discusses the initial operational problems encountered in implementation of the propellant/perforating technique and the precautionary methods that were taken to address these scenarios.

“…The system is an excellent substitution for a clean-up stimulation in carbonates and dolomites formations. 4 By combining completion and stimulation into one operation, the well comes on line more quickly with less expenses, resulting in quicker and greater profits. Case histories will show the success of this process when used as a near wellbore clean up tool, for pre-frac preparation, and to eliminate other service needs.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractThe digital technology trends to transform the hydrocarbons production dynamic and can potentially increase world oil reserves. Several inherents systems and techniques are right now commercially availables, although the support of specialized hardware is required for completing truly integrated projects.Five key and high quality technologies-remote sensing, visualization, intelligent drilling and completions, automation and data integration-are a set of tremendous new tools that will enable energy companies see reserves more clearly, plan optimal drilling and production strategies, and manage operations more efficiently.The Inter-well seismic imaging, 4D optimized seismic and other key technologies in coherence cubes are the most recent advances speciality with great value for reservoir management.Crosswell seismic imaging is the first technology that fills the information gap between surface seismic and well logs and enhances the profitable management of subsurface hydrocarbon resources.Reservoir dynamic simulation models, running in conjunction with real time sensors and automated controls, provide high importance information, and the operators can visualizate efficiently subsurface conditions to maximize production and manage efficiently field development.Scalable 3D visualization technology combined with massive data management capabilities and high-speed networks are drastically reducing cycle times for prospect generation, field development planning, well design, drilling and completion.This paper shows examples of high resolution crosswell seismic visualization, downhole sensors systems, massive data capture with integral systems, and other technologies supported with digital resources as intelligent drilling and completions, which are generating an increase in the productivity in many scenarios and reservoirs in Mexico and worldwide.
