Deriving a risked development plan for a resource play has typically involved looking at several development scenarios and well counts separately and then tying these together in some form of decision tree approach to come up with the total risked evaluation. This approach often causes problems for the infrastructure and midstream groups as they are asked to provide strategies for various reservoir options that are not easily visualized. A new approach described in this Case Study involves the use of an integrated toolset that allowed for several completely different development scenarios to be analyzed that were based on a risked evaluation of the play. The ease in which the development scenarios are combined allowed the team to quickly determine a range of possible outcomes and clearly understand the medium to long-term capital requirements of the opportunity. The visual nature of the outcome improved the decision makers' overall understanding of the development. For this specific South Texas resource play opportunity, the extent of the formation was poorly defined and only seismic and analogy data were available to define a range of possible reservoir characteristics. Based on analogous data, several different potential reservoir production models were defined and the extent of the reservoir estimated. These assumptions were then turned into various realizable development options including their economic values. The process and workflow of how the production options were turned into economic models is the focus of this paper. By creating a network flow diagram of the options, decision makers were able to better understand the range of possible outcomes; including the capital and infrastructure requirements of the options. This approach significantly improved the communication with the team and significantly reduced the development option preparation time. By facilitating more engaged discussions around the development options, the entire team was able to better evaluate the opportunity and the capital requirements. Although this was a relatively small opportunity (9 wells maximum), the same approach is equally applicable to the major unconventional resources being developed worldwide. Source

Introduction: Unaccountedfor solids deposition in oil and gas wells can significantly impact production rates and overall well performance. This study evaluates the impact of including a solid slow-release scale inhibitor in the stimulation package as it relates to production enhancement. While this study focuses on the Eagle Ford in LaSalle and McMullen Counties, correlations to similar formations can be made. The Eagle Ford shale is recognized as a prolific unconventional play that has very dynamic production challenges. Many issues can be experienced shortly into the life of the well, although observable scale does not manifest early on in many cases. Application: A major Eagle Ford operator saw a financial and operational benefit in establishing long-term scale treatment with a single application. The operator opted to use this solid inhibitor to extend the treatment life, to reduce subsequent intervention costs for solids removal, and to maintain proppant conductivity. Through the application of this solid chemical, the operator was able to place the inhibitor deep in the fractured formation before the first instances of pressure and temperature changes. The particle slowly releases the adsorbed scale inhibitor into the bulk water as it flows through the propped zone, providing immediate and long-term protection against solids deposition. Solids deposition can restrict production pathways through the proppant pack, contributing to loss of conductivity. Results, Observations, and Conclusions: Through the use of empirical data, this paper describes the relationship between an increase in total dissolved solids in produced water to an increase in production when compared to untreated wells. Post-stimulation monitoring of treated and untreated wells show a substantial differential in water composition, indicating that when left untreated, solids are precipitating in unseen places like the proppant pack and perforations. The operator has been able to operate more efficiently and show an increase in production while saving valuable time and cost on scale remediation during the well's life. Significance of Subject Matter: While it is understood that there are multiple contributors affecting a well's production, mitigating solids deposition in the proppant pack plays a substantial role. Removing solids from the well can reduce damage to the proppant conductivity and result in production enhancement. Copyright 2015, Society of Petroleum Engineers. Source

The Guyana Shield has long been interpreted as the source of siliciclastic detritus within the Cretaceous passive margin strata of northern Venezuela. We have determined U-Pb ages of detrital zircons separated from Early Cretaceous strata of the passive margin. Although the Guyana shield is the probable source for much of the Archean, Paleoproterozoic and early Mesoproterozoic detrital zircon grains, there is a prominent age population (ca.0.95-1.2Ga) that is not easily explained as being derived from the shield. A western source in the Venezuelan and/or northern Colombian Andes is suggested for this detrital component. We propose that a Proto-Orinoco river system drained both the Guyana Shield and the Venezuelan and Colombian Andes and that branches of this river system were funneled through Triassic/Jurassic rift basins that formed during initial opening of the Proto- Caribbean Seaway. The detrital zircon age data have implications for paleogeographic reconstructions of the Caribbean region prior to the breakup of Pangea and the longevity of continental scale river systems. Source

Kim Tran explains how bringing on young engineers in a closely monitored mentoring environment improves performance. The number of graduates from petroleum engineering in the US has increased steadily since the oil boom several years ago and continues to grow despite the recession. Young engineers provide a great resource to companies; they are eager to learn and absorb information quickly. The downside is that this younger generation is not being trained as its predecessors. Today, some of these companies still maintain the same training program but have incorporated rotational assignments to allow engineers to gain a more comprehensive level of training that encompasses all areas of drilling and production. Swift Energy Co. has brought young and experienced engineers together in a mentor environment where performance results are expected from the mentor/mentee duo. Source
