... Abstract Due to reservoir conditions in the Apika-Nenke field, it was decided to carry out a hydraulic fracturing pilot project with the aim of maximizing production in the field. To achieve the objective, cores, image logs, pressure points, and sonic dipole logs were obtained to have...

..."), which reduces the production life of the horizontal producers due to a fast water influx from the aquifer. The latter represents the main objective of this study. Aquifer water encroachment into the reservoir oil bearing zone significantly affects the productivity of completed wells, manifested...

... Where water is incorporated in these models, initialization is done with high water saturation in the red regions to represent hydraulic fracturing flowback water, regardless of using single or dual porosity models. In most cases, formation water production from the shale matrix is negligible...

... the fractures half length, height, volume and conductivity/permeability that ruled the early behavior of the wells and the matrix permeability that conditioned their longer term productivity. Controlling the wells in the history match was found to be best achieved by control through the choke and line pressure...

... Abstract In an scenario that shows how expensive conventional drilling has become in Ecuador, with the aggravation of the oil price collapse, Operator's reaction was to opt a new strategy focused on optimizing drilling operations by managing some tolerable risks, which increase productivity...

... Abstract The "Oriente" basin is located in eastern Ecuador between the Andes Mountains and the Amazon rainforest. In 2012, daily oil production reached 505,000 barrels. The three main oil-bearing Cretaceous formations in the basin are the Hollin, T and U formations. Results from recent...

... clean and effective. The first application of CO 2 in Saudi Arabia is discussed, highlighting its success in terms of 50% increased productivity, quick cleanup, and reduced water volume. Classically, conventional hydraulic fracturing (acid or proppant) has been used to maximize long-term production...

... Abstract Hydraulic fracturing is the most common stimulation technique to make hydrocarbon production feasible and optimal worldwide. However, it has been preferentially focused on low permeability formations, and when applied to high permeability, it has been focused on sand control...

... Abstract Petroamazonas EP is the national oil company in Ecuador. It holds most of the oil concessions Onshore and Offshore in the country. The oil and gas production targets require implementing advanced analysis that provides effective results on production. In order to analyze and predict...

... Abstract There are several techniques to optimize production and avoid reservoir damage caused in the different phases of the development of oil wells (perforation, completion, production and workover), ranging from the control of water, chemical stimulation, mechanical stimulation, fracture...

...Introduction Abstract In this paper we describe a perforating technology that helped deliver highly productive wells in the Tunu field, a multilayer sandstone gas reservoir in Indonesia. We describe the simulation models used to evaluate perforating designs and operational risks, and we...

... Abstract Sand production in oil and gas wells is a complex problem that requires a multidisciplinary analysis to arrive at an optimal solution of the problem and thus increases the productivity of oil fields with problems of production of sand. Many operators choose as first alternative...

... The south of Boscán covers an area of the field that is 20 km by 3 km ( Fig 4 ). OOIP in this area is estimated at 7.1 BBO. Current cumulative oil production is only ~0.25 BBO or ~3.5% of the OOIP has been produced. 25% of the total field production is produced from this area with approximately...

... Abstract Sand production in oil and gas wells is a complex problem that requires an integral analysis of rock mechanics, mineralogy, granulometry, etc. that allows a risk management in order to make the best technical and economic decision. In this study the background, strategy used...

... Abstract After workover jobs, many oil-producing wells have reduced their production, which is caused by formation damage created by using inadequate completion brine. The damage mechanism may be: 1) Block in the face of the formation, produced by the tendency to form emulsions between the oil...

... Abstract More than 70% of global oil production derives from mature fields. With current elevated prices, the revitalization and optimization of these fields are of great commercial appeal and interest. However, revitalization requires technologies and procedures for quick analysis...
