This lecture presents approaches for increasing production from horizontal wells with multistage fracture (HWMSF) completions in conventional reservoirs. HWMSF completions are now regularly being drilled and completed in low-to-mid-permeability oil-bearing conventional reservoirs (k<10 md) where the oilfield is under waterflooding. Although the industry has closed the HWMSF technology gap of drilling and completing these wells, the productivity has been below the expected levelThe production is characterized by either an early-time relatively high production rate followed by a steep production decline and water breakthrough or low initial production and even lower late-time production. What went wrong and what can be done? The lessons learned in unconventional reservoirs are not pertinent to conventional formations. Hence, the problem was examined from the reservoir standpoint, focusing on achieving adequate pressure support to maximize drainage, revising the waterflood process through drilling patterns, and evaluating the specific completion techniques. Equally, the question warrants answers on current HWMSF restimulation, addressing methodology applied to specific completion design, the horizontal wellbore azimuthal orientation within the stress field, and, finallythe operating condition of the injector and producer wells. The lecture discusses novel designs for refracturing and for future reservoir development, and, at the same time, is a plea to the drilling, completion, and reservoir engineering teams to integrate their competencies to optimize these complex production systems.

This lecture covers the application of the system engineering approach to the creation of the software "Drilling Value Engineering" to predict the cost of a well. The product development was carried out according to the V-model of the life cycle, in which the following stages were passed: requirements engineering, functional design, synthesis, implementation, verification and validation. At each stage of the life cycle, the necessary practices and tools were applied: identification and interviewing of stakeholders, methodology development, prototyping, conceptual model, functional requirements, database model, external environment of the system, technical design and architecture of the system, testing for the achievement of goals. Joint work of technical drilling specialists, IT architects, programmers, business analysts at all stages of the life cycle of the system development made it possible to make a unique IT product that allows to assess the cost of oil and gas project wells at different stages depending on the amount of available information. Application of system engineering practices in the implementation of the project "Value Engineering Drilling" allowed to effectively pass the main stages of the IT project and create a unique product for integrated well cost assessment. Testing of the system for the set business tasks and requirements of stakeholders shows the success of this approach and achievement of the declared business effects. Next, a new stage of ISIS development will be launched, and the V-model will be transformed into the W-model. The main tasks are: integration of the IS "Cost Engineering Drilling" into the Conceptual Engineering System of PJSC "Gazprom Neft"; improvement of input data details and depth of the existing functional capabilities of the system; development of a new functionality of the matrix system for assessing the cost of construction of wells under the range of changing conditions; expansion of the organizational volume of the project.

The “Fracts” of Life


Hydraulic fracturing is the single most commonly applied completion and intervention approach across the globe, from high-permeability reservoirs at one end of the scale to hard to recover formations at the other.  Constantly, changing, adapting and challenging established thinking, it is one of the most successfully applied techniques that is used within the oil and gas industry. 

While we are all taught and introduced to fracturing theory and fundamentals, there is no real replacement for extensive operational exposure and experience, in planning, executing and working with hydraulic fracturing operations in a variety of situations.  It is through this particular lens that some of the key factors, themes and consistent issues can be fully appreciated, registered and subsequently acted upon. 

The purpose of this presentation is to outline, impart and share, those major issues that directly impact the potential success of hydraulic fracturing operations, that have presented themselves to this Lecturer, particularly in new/overseas areas.  This feedback is based on more than 30 years of performing Exploration, Appraisal and Development operations; in diverse, frontier and challenging environments across some 35 Countries and many Basins.  The themes and advice will be shared by means of actual case histories. 

A successful Lecture would result in a refreshed and focused awareness of the relative importance of these key factors on successful operations.  The lessons learned are multi-disciplinary in nature and this renewed level of awareness will generate fresh perspective from the attendees, and encourage open discussion with their colleagues from other disciplines, on fracturing understanding and interpretation.  This is particularly important as large scale fracturing developments extend into new International areas, where skillsets and experience will sometimes be less well established.

Abstract: Unconventional reservoirs have had tremendous success over the last decade due to technical advances including long horizontal wells and multi-stage hydraulic fracturing; however, their potential may be even higher. There are trillions of barrels of oil in these resources, and while wells start out at high rates, they decline quickly and primary recovery factors are low, often in the single digits. This clearly indicates a need for some form of enhanced oil recovery (EOR) for these types of reservoirs. In this presentation, the efforts to implement EOR in unconventional reservoirs will be examined in full detail. A number of different injection fluids have been proposed including miscible gas, water and surfactants. Early work focused on modeling and lab studies, and this provided a base of knowledge that was leveraged to carry out pilot field studies. Pilots have been implemented in at least four basins, and the Bakken and Eagle Ford have both had multiple field trials. Huff-n-puff natural gas injection has been shown to be very successful in the Eagle Ford, and today, large-scale field development is occurring there. Because most of the field trials have been completed in North America, the examples presented are mainly from there; however, as these techniques are reproduced in other basins, the worldwide potential is enormous, and that potential also is discussed in the presentation. While much has been achieved over the last decade in unconventional reservoirs, implementing EOR in these types of reservoirs will likely bring about even greater success.

Enhanced Reservoir Characterization and Well Performance with Integration of Static and Dynamic Data  

Reservoirs can exhibit heterogeneity in terms of porosity, permeability, in shaly sands  and in carbonates along with   fractures, vugs, including wettability.   This heterogeneity affects the well evaluation, horizontal well placement and performance estimation that would be crucial for completion, testing  and reservoir management decisions.   

This presentation will discuss a methodology for reservoir characterization, geological modeling, and well performance prediction by integrating a complete suite of petrophysical and pressure transient test data to build a detailed geological reservoir model with permeability anisotropy 

Production logging has traditionally been used for problem well diagnosis and flow profile in vertical wells and increasingly in horizontal wells in the recent years. It will be shown how the methodologies and the field examples of horizontal production logging can reveal the heterogeneities and aid to reservoir characterization with the integration of numerical  Near Wellbore Modeling (NWM) and the production logging in a multilateral well to obtain layer permeabilities Production logging also becomes crucial for the diagnostic of fractures, spatially distributed Several field examples of comprehensive production logs with the analysis will be shown with examples  

Multi well comprehensive static and dynamic data integration  is also shown to evaluate water sweep, diagnosing reservoir dynamic performance of heterogeneous reservoirs in a mixed salinity environment.

In the current oil and gas environment, operators have focused on production optimization, effectively squeezing every last drop of oil out of their wells. Autonomous Inflow Control Device (AICD) technology has been deployed as part of the completion in old and new wells resulting in increased oil production by reducing water and gas production. For many years, inflow control devices (ICD), which restrict flow by creating additional pressure, have been used to mitigate this problem. They are however, passive in nature and after the onset of water or gas breakthrough, the choke effect cannot be adjusted without intervention.

The AICD is an active inflow control device with a self-adjustable design to self-regulate and provide greater choke when an unfavorable fluid such as gas and water ingress. This prevents the well from being flooded when unwanted fluids breakthrough, therefore providing the advantage of being able to even out the inflow into well. In addition, it will also choke the unfavorable breakthrough sections of the well and producing from remaining sections leading to greater recovery, lower water, and gas production.

This technology has helped improve recovery in horizontal well across the globe by reducing gas-oil ratio or water cut of the well, thus increasing ultimate oil recovery. The key factor to successful application is a systematic approach in prediction modeling and well design workflow to select a well candidate between Passive and Autonomous inflow control device.

New approaches to the study of wells

Currently, the methods of marker (tracer) diagnostics, which allow obtaining qualitative and quantitative data on the operation of well intervals without performing downhole operations, are becoming more common in the world. The principal difference between these technologies and traditional well logging methods (GIS) is the ability to monitor the operation of multiple hydraulic fracturing or well intervals over a long period of time with a significant decrease in the resources involved, a reduction in costs and an increase in production safety.

Well studies using marker technologies can improve the efficiency of diagnostics of inflows in wells when developing oil and gas fields and solve a number of important tasks, such as: ∙ evaluation of the well flow profile after the multi-stage hydraulic fracturing; ∙ evaluation of the performance of each step in water and oil; ∙ optimization of technical solutions for well completion in the early stages of field development; ∙ analysis of potential long-term fluid recovery; ∙ obtaining detailed information for analyzing the mutual influence of neighboring wells; ∙ obtaining information on the dynamics of production of the oil reservoir area.

Also, in addition to an alternative GIS method, technologies for marking downhole equipment can be used for flow measurement data in the WEM layouts and in monitoring the integrity of the packers. The key topic of the report is the methodology for integrated assessment of the efficiency, reliability and accuracy of work for various marker technologies available on the market. Often, oil and gas companies decide on the use of marker technologies without any testing or testing, based only on the reputation of the supplier, the duration of its presence in the market or value. The reason for this may be the lack of standardized test methods, as well as experience in sharing best practices between subsoil users. At the same time, marker technologies are a relatively new field of activity in the field of well studies, therefore, it is necessary to approach the assessment of technologies on the basis of objective indicators.The report presents the results and methodology of testing various marker technologies that can be used as technical criteria when choosing a contractor for marker research.

Hydrocarbons in oil fields are affected by various secondary processes, such as biodegradation, migration of deep-seated gas, movement of formation water, and evaporation. The degree of hydrocarbon changes depends on many factors: reservoir temperature, tectonic activity, dissection of productive strata, activity of water-bearing horizons, etc. In this connection, oil initially migrated from one source rock varies differentially in different reservoirs and parts of deposits. Using high-resolution gas chromatography, it is possible to identify differences between oil samples from different formations and formation sections. Assessing the degree of secondary changes allows you to identify oils of various reservoirs, in other words, to determine the unique appearance of oils - “oil fingerprints” or otherwise the final members. Having a set of unique “oil fingerprints” - the end members representing the reservoirs being developed, it becomes possible to determine the contribution of individual reservoirs to the production of mixed products. This information can be very valuable both for solving current development management tasks and optimizing a long-term oil field development strategy. This paper presents the results of a pilot project on the introduction of geochemical analysis of oil using oil fingerprinting technology based on high-resolution gas chromatography into the development management process of the Astokhsky section of the Piltun-Astokhsky oil and gas condensate field. operating several layers with the subsequent practical implementation in production. In the course of work, the broader possibilities of the method were also identified, namely, monitoring of interfacial flows, clarification of the geological structure of the field, identification of leaks in production wells.
