... Abstract There is a large technological gap between the end of the frac and until operators accumulate long term production data to perform a meaningful lookback. Over the last 10 years flowback analysis (FBA) has emerged as a successful technology to address this problem by utilizing only...

Combining extensive in-house pumping data and well-production data available from the public domain, a two-dimensional approach cross-plotting total effective energy injected per unit area against production output shows a highly correlative positive...

... to acreage constraints, wells are drilled to maximize the number of wells instead of the ideal orientation with respect to subsurface stresses. We studied the impact of changing well orientation on well productivity in the Bakken Play by simulating a wide range of operational scenarios including proppant...

.... Additionally, its well productivity is hampered by low matrix permeability. Addressing these challenges is crucial, and a successful acid fracturing process can not only enhance well productivity but also address Asphaltene-related problems. This study delves into a comprehensive methodology that was employed...

This includes an appreciation of the production/economic profile and exposure to risk, which is hugely different in say an ultra-deep-water five well offshore development vs. a field development with some 100s – 1,000s of wells in a lower-cost onshore...

... technique. The paper will describe the original development of the TSO process, design, deployment, refinement, and its broader application. A suite of case histories will demonstrate that every major operator in every major basin worldwide has successfully applied this technique to enhance production...

... Abstract Fiber optic measurements including Distributed Acoustic Sensing (DAS) and Distributed Temperature Sensing (DTS) have been established as common tools to monitor the downhole condition during hydraulic fracturing treatment as well as during production. Several authors presented...

... objective of this study is to quantify and compare the effects of reservoir quality and completion intensity on well productivity. We developed a supervised fuzzy clustering (SFC) algorithm to rank reservoir quality and completion intensity, and analyze their relative impacts on wells' productivity. We...

..., completion design, and reservoir parameters. We evaluate the effectiveness of the stimulation operation by comparing the impact of operation decisions on the created fracture geometries and simulated productivity of the propagated fractures using seamless fracturing-reservoir simulations. The simulation...

... Abstract It is common in unconventional plays to have offset wells with very different productivity, even though these wells were drilled at the same time, in the same landing zone and with the same completion design. Such well behaviour is always puzzling because subsurface properties...

... An appraisal programme is the post exploration phase, where the presence of the hydrocarbon accumulations has already been confirmed, but productivity and commercial viability remain to be proven. The appraisal phase typically consists of deploying a suite of selected technologies...

This was done in order to account for changes in the reservoir along the horizontal lateral. Production log results showed on average a 19...

An evaluation of large datasets from publically-derived completion and production data to statistically evaluate the successes of different completion practices and a couple of specific case studies will be presented to illustrate some ways where operators can exceed the statistical mean well...

... Abstract Unconventional shale resources are key hydrocarbon sources, gaining importance and popularity as hydrocarbon reservoirs both in the United States and internationally. Horizontal wellbores and multiple transverse hydraulic fracturing are instrumental factors for economical production...
