... effects on general well patterns. The originally designed flooding units are broken up, and new pattern units are made up of the wells that belong to different original units. The behavior possesses strong randomness, and leads to the chaotic relationship among the injection and production wells...

... Abstract Several innovative techniques and practices have been recently implemented to improve well production performance in offshore assets in the Arabian Gulf. The challenges which followed past practices were identified and intensive work was focused on enhancements to existing well...

... Abstract Horizontal well technology has been widely used in developing gas fields. Very commonly, these wells are hydraulically fractured to improve productivity in low permeability reservoirs. A previously developed method, the Distributed Volumetric Source method (DVS), was applied...

... as a boundary condition for the reservoir system. Potential stimulation and completion techniques are compared by three measures: Effective normalized cumulative hydrocarbon production, volume fraction of the influenced reservoir domain, and normalized damage ratio. Performance and economical analyses...

... an increase in the initial productivity of the new wells on the order of 25%. The study found that a massive waterflood in the Intermediate formations can help extend the production plateau and recover additional reserves by seawater injection. The study also found that the gas injection requires surface...

... Abstract An integrated analysis of technical information from 459 wells that were shut in or having production problems within five Integrated Business Units in the Southern Region of PEMEX E&P, identified production increase opportunities of more than 145,000 STB/D of oil and 323 MMscf/D...

... was based on oriented water flooding patterns and massive hydraulic fracturing, together with an artificial lift system equipped with permanent pressure and rate monitoring for evaluation and real time production enhancement. The optimization of operational practices and introduction of fit for purpose...

... Abstract Breathing new life into a mature oil field is a challenge that has been facing national and private oil companies for almost as long as the oil industry has been in existence. Oil production from mature fields accounts for approximately 70% of the worldwide oil production...

... the reservoir development. This multi-scale flow makes it tougher to analyze the well productivity than that of a conventional reservoir. In this paper, muti-rate well-testing data were used to calculate the production capacity at different reservoir pressures in naturally fractured reservoirs. The method...

.... Many field procedures in use for hole cleaning and barite sag today are the product of extensive flow-loop testing by the industry and correlations with field results. For hole cleaning, analytical models developed over the years have been complemented by practical field guidelines. 9 For barite sag...

This paper offers insight on drilling and completion strategies based on experiences in two South American locations with distinct structural styles. One is a Devonian gas discovery in Bolivia and the other a block...

... Abstract When drained volumes want to be increased or to reduce investments with additional drilling wells, we can use horizontal wells as a good alternative for optimum exploitation of the oilfields. This is supported because the horizontal wells productivity becomes higher than in a vertical...

... Abstract Although horizontal wells may offer significant production improvement over vertical wells, it may be necessary to fracture horizontal wells to maximize their return on investment. This is especially true in the case of tight gas formations. This paper presents a model for fractured...

... ABSTRACT A multi-phase effort that involved geological, geophysical, and petroleum engineering studies yielded an improved understanding of naturally fractured reservoirs and potential manners to improve the incidence of oil production from such reservoirs. Maps of fracture traces on bedding...

... Abstract The Fault Block Model was designed for the devel-opment of gas production from Sleipner Vest. The reservoir consists of marginal marine sandstone of Hugine Formation. The structure is dome shaped and highly faulted with good reservoir productivity. Based on geological interpretation...
