ESP Surveillance and Optimization System in “Smart Fields” of Salym Petroleum Development


Anastasia Musorina

Salym Petroleum Development - Production programmer (WRFM)


She has more than 7 years of working experience in oil production companies in the area of monitoring the operation of ESPs (electrical submersible pumps), proactive monitoring of oil production and water injection indicators in the area of waterflooding, determining deviations from expected values ​​/ operating limits in order to introduce corrective actions. She is a member of the SPE and a member of the Organizational and Technical Committees of the International ESP Symposium - SPE Electric Submersible Pumps Symposium, Houston, USA - the largest ESP event in the world. Also she is the author of articles in Russian and foreign industry books and magazines.

In current conditions of oil and gas production the highest significance is the use of intellectual control technologies improving operational activities of the company. The main task of intellectual system is optimization of production, technical solutions, processes of planning and operational expenditures.

SPD pays significant attention to issues of optimization of oil production and production energy efficiency, and in this relation in the beginning of 2016 the company developed and implemented a program of daily analysis of production well stock operation and making decisions on optimization of their operating modes called “Optimization Register”. 

This system is integration of well and equipment operating parameters  in real time mode and technical information from different databases into one base with automatic check of data correctness. This allows to promptly draw attention of Analytical Engineer to arising problems with the well, create a request for actions to re-establish operating mode and send the request to responsible persons for implementation of required actions to stabilize its operating mode. All requests are created in the program and automatically sent to performers. Time of request submission and its closure is strictly recorded by the program, which allows to assess prompt work of different services in the company.

Automatic detection of destabilization of well and/or equipment operating mode, creation and implementation of requests within limits of work optimization now presents a closed cross-functional cycle of information delivery allowing each participant to have all updated information on specific well and leave comments related to his/her responsibility area.


Sand production due rock failure can have a severe impact on the economics of an oil or gas field. Erosion of the downhole or surface components by sand can lead to loss of integrity and hydrocarbon leakage. Production rates may need to be reduced to limit sand from flowing to the surface or filling the wells. Sand handling, either at surface or flushing from downhole, adds expense to lifting costs.
Poor completion decisions at the beginning of production can risk the viability of the field sand management over the life of a field, to maintain economic productivity, needs accurate prediction of sand failure and completion design to increase both productivity and ultimate recovery.

This talk will explain the root cause of sand production to solution. The geomechanics aspect of the rock itself honoring the physics of solid and fluid mechanics relevant to sanding from weak or very weak sandstones, and then uses this understanding to suggest ways of designing screenless completions to take advantage of these aspects to avoid and/or control sand production.
This presentation aims to explain questions on why, how, when and where, how much related sand production. Discuss the methodology to forecast the sand production mechanicsm. Finally the mitigation plans using perforation strategy and completion options. The benefits for life of the field either to avoid or control the sand produce to surface

The discovery of Nuclear Magnetic Resonance (NMR) phenomenon spawned innovative diagnostic
technologies that facilitated advancements in a wide range of disciplines including medicine, chemistry
and earth sciences. Geologists observed that in a manner similar to Magnetic Resonance Imaging (MRI)
that revolutionized medical imaging, NMR measurements illuminate pore-filling fluids inside a porous
rock and provide unique insight to porosity, pore size and/or fluid viscosity without any damage to the
For the oil and gas industry, this sensor technology has become everyday reality with the development
of NMR well-logging tools. Since the first modern NMR logs in the early 1990s, NMR logging enhanced
formation evaluation in complex reservoir rocks such as heterogeneous carbonates and silty sands and
enabled reservoir fluid characterization in the presence of fresh water, heavy oil or variable gas-oil ratio.
More recently, with the development of logging-while-drilling (LWD) tools, NMR petrophysics is
available for real-time reservoir navigation.
With these advancements, upstream operators can realize significant value in their exploration,
evaluation and field development activities. First, the cost and time savings by optimizing formation
testing, sampling and well testing operations thanks to the more accurate reservoir quality and fluid
mobility evaluation significantly outweigh measurement costs in most cases. Second, NMR logs uncover
hidden reservoirs with low resistivity contrast in the presence of laminar shales or carbonate
microporosity. Finally, NMR-driven placement of injector and producer wells reduces field development
costs and potentially increases hydrocarbon recovery.
This lecture shares the lessons of two decades of learning by an experienced operator with field
examples that show how to increase operational efficiency and improve reservoir understanding with
wireline and LWD NMR logging technology. Participants are encouraged to bring their own logs for
customized review and discussion.

scientist at Baker Hughes in various positions for 10 years on downhole NMR instrumentation and data
processing software development. He has MS and PhD degrees, both in Geophysics. He published over
40 papers and patents, teaches in-house and external courses in NMR logging. He serves SPE and SPWLA

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.
