.... To increase production, they adopted infill drilling and completion techniques to increase the stimulated reservoir volume and increase production. However, drilling these wells close to each other has resulted in interference of production known as fracture-driven interactions (FDI) between the wells...

... Abstract As the number of greenfield and brownfield development opportunities dwindle, many operators are looking to refracture older existing wells for additional hydrocarbon production. While it is generally understood that a bigger second completions job will yield more oil production...

... reservoirs, these parent–child interactions are growing more intense because the average length of time between parent well and child well completion dates has been increasing, resulting in broadening of the pressure depletion zone surrounding the parent wells. During completion of the child well(s...

... well and are the primary focus for operators trying to reduce related operational losses. Infill drilling with reduced well spacing and larger completions after significant reservoir depletion, are factors that can increase FDIs events and the risk of negative impact on infill and primary well...

... Abstract The development of unconventional plays has yielded valuable insights due to advancements in completion technologies and the identification of optimal drilling locations within plays. Among the notable techniques in the current commodity market, refracturing treatments have gained...

... Abstract Refracs have historically been difficult to design, complex to execute, and results largely unpredictable. Under normal circumstances initial completion designs have many unknown variables, including reservoir quality along the multistage lateral, as well as the far field reservoir...

... Abstract Flow regime changes are important to capture and predict when estimating the future production from tight oil wells. Due to the nature of hydrofracture completions and reservoir heterogeneity, flow regimes are difficult to predict before they are observed. Also, while some wells...

... closely tied to the business scale and success. One first order driver of financial results is the tradeoff between well density and completions intensity which involves assumptions about producing reservoir volume and completed reservoir volume. The complexity of unconventional reservoirs prevents...

.... Two historical wells were selected for the basis of the two-phase study. Well A and Well F were originally completed with 100- and 67-foot cluster spacing, respectively. Each well was refractured after three years of primary production. In Phase One, a model of each well was constructed. Each model...

... Abstract Expanding upon the former paper “Completions Optimization and Fracture Evaluation of Infill Wells: A Southern Delaware Basin Case Study”, a high-viscosity friction reducer coupled with increased proppant concentration and reduced fluid volume load was utilized to restrict fluid...

... Abstract An operator was in the process of planning to develop a single section in the Northern Delaware Basin targeting a multi-bench reservoir. With limited historical field data the operator sought to quickly optimize production and maximize returns on this acreage. The completion had...

...), are studied to evaluate hydrocarbon production and future production enhancement. Early phase of the evaluation includes petrophysics, geology, well/completion engineering, and reservoir engineering. In both well groups, petrophysical data were collected from the vertical offset test wells and were utilized...

... due to wet zone completion. Rather, the increasing water cut trend is mostly because of improved completion methods, increased well density, and aggressive production techniques that speed up fluid withdrawal rates. Without pressure maintenance from injection, gas cap expansion, or aquifer influx...

... Abstract Early development of the Delaware Basin Wolfcamp focused on exploration, lease holding, and operatorship capture. As a result of this early development strategy, many sections now possess a single horizontal well with an early vintage of completion technology. These standalone wells...

... Abstract This investigation reviews the vertical distribution of organic-rich sequences in Upper Cretaceous rocks of the northern Denver Basin. The primary objective is to provide a more complete definition of the effective source rocks in this sequence. Multiple organic-rich members...

... Abstract It is generally understood that the types of completion designs utilized in early shale wells (e.g. wide cluster spacing, high viscosity fluid systems, poor perforating charge selection, etc) led to EURs that are significantly less than what is achievable today using modern techniques...

... stimulation. The assessment of the production along the wellbore as well as interactions between wells provides an understanding of the variability of inter-well connections and reservoir characteristics. These data and their analysis can then be utilized for optimizing future completions and well performance...

... Abstract Moment tensors for microseismicity are frequently used to tie to the geomechanics of completions, as they inform on the fracture sets that are being stimulated and they are expected to be congruent with the dynamic (perturbed) stress state. These quantities, being a bridge from...
