Objective and scope The objective of the work is to present an adequate workflow for conditioning geomechanical data and hydraulic fracturing design, adjustment and simultaneous verification of a MEM and hydraulic fracture models. These approaches are relevant for greenfields and also can be used when changing field development systems: from vertical fracked wells to a system of horizontal wells with multistage fracs. Methods, techniques, and process description The paper provides examples of issues in hydraulic fracturing planning due to poor attention to the reliability and robustness of geomechanical data. Given the critically of data quality, the authors describe a holistic approach used in collecting, analysing and conditioning data for building a MEM (1D; if necessary, 3D) as the basis of a frac design. Mini-frac is considered not only as a tool for setting the hydraulic fracturing design parameters, but also as a source of data for cross-calibration between the MEM and the hydraulic fracture models. Case studies of various HF models will demonstrate the influence of MEM-and-frac uncertainties and the tools for considering them in practical HF modelling. An approach to systematic clustering of input data for HF designs is described. The importance of measuring the fracture heights is stressed as a source of data for cross-calibration of HF and GM models. Results and conclusions The correct sequence of work, data consolidation and successive data refinement helps to maintain the database of elastic and strength properties of various target reservoirs, which proves the demand for core analysis and well logging, as well as geomechanical modelling. The improved quality of HF designs leads to better reliability of forecasts and proposed field development and individual wellwork strategies. The close integration of GM studies and modelling with HF design building enhances the operation culture, accelerates and streamlines the HF model build and validation processes, which can be a pace-setting experience for other oil and gas industries that are GM data users. Novelty and achievements The TNNC and RN-CEPiTR teams work in close cooperation and provide GM and HF integration to assess the fracture height in the target reservoirs at the Company's assets in order to improve the quality of HF modelling. The uncertainty influence on the HF design is reducing, so as the risks of screen-out and the risks of breakthrough into undesirable zones. The approach streamlines the engineering support for the hydraulic fracturing activity and understanding of the fracture parameters as the operations move from single-stage hydraulic fracturing to the optimized field development using horizontal wells with multi-stage hydraulic fracturing.

Abstract The choice of the optimal trajectory of horizontal and directional wells, the placement of frac-ports for multistage hydraulic fracturing, taking into account prepared input data (using geological and geomechanical modeling with the rock properties anisotropy), provide optimization of hydraulic fracturing operations and field development. Formation T contains more than 3 trillion m of gas, and is already an object of close attention of the largest oil and gas companies. The unique character of the object is due to the high reservoir compartmentalization of the collector and low permeability. Therefore, the main development strategy for the reservoir is to drill low-angle and horizontal wells, followed by multistage hydraulic fracturing. The main goal of multistage hydraulic fracturing is to join productive intervals and at the same time avoid undesirable fracture breaks into neighboring layers. To achieve this goal, several tasks were solved: creation of a petrophysical and geological basis for geomechanical modeling, creation 1D and 3D geomechanical models taking into account the rock properties anisotropy due to the high layering of the reservoir, and preparing input data for hydraulic fracturing design. For the qualitative creation of the geomechanical model at the observation wells of the field, an expanded complex of special well logging studies has been performed, borehole measurements of reservoir pressure and minimum horizontal stress have been carried out according to the results of stress tests, core sampling and research to determine petrophysical and mechanical properties. The analysis of the obtained information revealed the features of the stress state along the section and reservoir area, which were taken into account in the design of hydraulic fracturing. Geomechanical modeling was carried out in a uniform work procedure, which made it possible to unify the result, improve the quality of calculations and forecast parameters for horizontal wells.

Abstract On the basis of geological, hydrodynamic and 1D geomechanical models based on full-wave sonic log, results of AVO-inversion from 3D seismic survey, a 3D/4D sector geological and geomechanical model of the Verkhnechonskoye field has been constructed. A large number of vertical wells with the availability full-wave sonic log data and its uniform distribution over the field area allowed us to characterize the research interval in details in terms of elastic and strength characteristics. A wide range of input data was used to calibrate the model: MDT and XPT data, core laboratory studies, and hydraulic fracturing data. It was the first time for the VCH1 and VCH2 groups formations of the Verkhnechonskoye oil and gas condensate field geomechanical model was introduced into the permanent geological and technological model of the field. A comprehensive approach has been implemented to assess the geomechanical risks of hydraulic fracturing over the field area with calibration based on the actual results of hydraulic fracturing.

Evaluation of the Saturating Fluid Effect on the Composite Materials Elastic-Strength Properties
Pavlov, Valeriy (LLC Tyumen Petroleum Research Center) | Pavlyukov, Nikolay (LLC Tyumen Petroleum Research Center) | Krasnikov, Artem (LLC Tyumen Petroleum Research Center) | Lushev, Mikhail (Halliburton Int. Inc.) | Eltsov, Timofey (King Abdullah University of Science and Technology)
Abstract Effective assessment of the stress-strain state of the near wellbore zone is one of the key problems in the process of modeling the stability of the wellbore walls. Drilling mud infiltrates permeable rocks during the drilling process. This causes a change in the elastic-strength properties of rocks and, accordingly, the redistribution of tension around the well. At present, there are no computational methods that take into account the effect of saturation fluids on the change in the elastic-strength properties. A unified system approach for the implementation of this type of research when changing infiltration fluids is not developed yet. In this paper, we study the effect of various types of drilling mud on the elastic-strength properties of core samples, which are equivalents of rocks (composite samples made of different sand and clay cement facies). Measurements of porosity, acoustic properties, ultimate strength for uniaxial compression, and static Young's modulus at different samples saturation are made. Studies of the elastic-strength properties of the samples are performed after 48 and 168 hours soaked in the drilling fluids. According to the study, the relative change in the dynamic Young's modulus with various sample saturation is 13.4-27.7%, the static young modulus (compression) is 19-40%, the dynamic Poisson ratio is 1.4-14.6% and the uniaxial compression strength is 28-35%. The data obtained indicate a significant effect of the saturating fluid on the elastic and strength properties of materials. A numerical one-dimensional simulation of the stability of the borehole walls is performed, taking into account the type of saturating fluid and the relative change in the elastic-strength properties. The results indicate a change in the stability of the wellbore walls; the indicators of the change in the equivalents of the collapse gradient and hydraulic fracturing are 0.2-0.3 g / cm. A change in Young's modulus of 30% affects the design parameters of a hydraulic fracturing fracture โ by width up to 100%, by half length up to 50%.

Well Placement and Operation Parameters Optimization of Horizontal Wells in the Development of the PK1 Reservoir of the Kharampurskoye Oil and Gas Condensate Field
Melikov, Ruslan (LLC Tyumen Petroleum Research Center) | Pavlov, Valeriy (LLC Tyumen Petroleum Research Center) | Subbotin, Mikhail (LLC Tyumen Petroleum Research Center) | Ptashnyi, Aleksandr (LLC Tyumen Petroleum Research Center) | Pavlyukov, Nikolay (LLC Tyumen Petroleum Research Center) | Krasnikov, Artem (LLC Tyumen Petroleum Research Center) | Korolev, Alexandr (LLC Kynsko-Chaselskoe Neftegaz) | Loznyuk, Oleg (PJSC, NK Rosneft)
Abstract Work objective and subject The main work objective is optimization of field development and well operations by providing recommendations on selection of optimal intervals for horizontal well placement and safe drawdown pressure limits in PK1 gas reservoir for minimizing risks of sand production. Up to 25% of the gas from the total recoverable reserves of gas assess of PJSC "NK "Ronseft" in the territory of Russian Federation is concentrated in PK1 formation, which makes it attractive for commercial field development. The uniqueness of the object is determined by the type of reservoir: highly porous and highly permeable weakly consolidated sandstone, which imposes a number of limitations on completion design and operating parameters. Used methods, technologies, process description A significant volume of special studies has been carried out to enhance quality and credibility of geomechanical modeling results: broadband acoustic cross-dipole logging, formation micro-imagers, extended leak off tests, pressure tests and fluid sampling, coring for complex petrophysical and geomechanical lab experiments. Based on the obtained information 1D geomechanical models were calculated for several offset and reference wells and calibrated on drilling results of first horizontal wells in PK1 reservoir of the Kharampur field. According to the results of 1D geomechanical modeling, calculations of safe and critical drawdown pressure are made for sand potential prediction during production. Specialized core samples tests are planned and conducted (thick-wall core cylinder tests) to calibrate modeling results. Results and conclusions Based on geomechanical model and the results of thick-wall core cylinder test, the values of safe and critical drawdown pressure along the wellbore were determined for initial reservoir conditions. It's defined that the planned interval of horizontal well placement in some parts of the study area is characterized by lower value of safe drawdown pressure (DD<2.5 atm.) than was planned in the preliminary field develompent strategy. To achieve the planned volumes of cumulative production, it is proposed to review the placement of horizontal wells in intervals and zones where the critical drawdown pressure corresponds with or may be higher than planned one. Novelty of work and achievements As part of project implementation, at the planning stage of the field development strategy an expanded set of advanced logging and measurements was carried out on a number of offset and reference wells to increase the reliability of the petrophysical and geomechanical models. To confirm the results of drawdown pressure limits calculation on the basis of geomechanical parameters a new method developed and special lab experiments (thick-wall core cylinder tests) were conducted for predicting several states of the rock during loading-deformation process and estimate safe and critical drawdown pressure. The results of geomechanical modeling are used as a basis for project design documentation and will be used to calculate the optimal parameters of well operation and increase the efficiency of field development.

Abstract The paper demonstrates the application of 3D geomechanical modeling results for: identifying zones of increased and lowered risks for entire area of the field, optimizing trajectories of production wells, and forecasting sand production in various productive horizons. Synthetic cubes of the ยซsafe drilling windowยป have been modeled for the typical design of the production wells in order to determine the intervals of increased risks from breakouts and mud losses point of view. Finite element method was used for 3D geomechanical modeling of the entire area of the field with usage of Local Grid Refinement (LGR) within the areas of active production drilling. The results of numerical modeling and elastic-strength properties of rocks was used for creation maps of drillability (gradient of pore pressure, gradient of breakouts, gradient of mud losses and fracture gradient) for various horizons over the entire area of the field to determine the safest zones in terms of drilling and zones where optimization of trajectories or well designs is necessary. Creation of the maximum possible depression maps before sand production occurs along the area of the field was made. Based on the drilling maps analyses, an example of the field demonstrates distribution of increased risks areas from drilling point of view and changes in the required mud weight or well design. Within the framework of the article will be shown the influence of existing tectonic faults on changes in the "safe mud weight window" and pressure before sand production will be determined. Based on the numerical modeling results, optimization of the field development system was proposed to reduce drilling related risks, optimize hydraulic fracturing design and reduce the probability of sand production. The necessity of using geomechanical modeling results on every ยซlife-cycleยป of the field and actualization of the created geomechanical models is shown. The example of the field in Eastern Siberia shows the possibilities of using 3D geomechanical modeling results to optimize drilling techniques, to reduce the probability of drilling related problems and problems related to sand production and completion system. The influence of geomechanical factors on different processes during field development is shown, which ultimately can lead to the optimization of field development plan by collaboration work with geologists, drilling and development engineers.

Abstract A 3D geomechanical model was constructed to estimate the influence of the initially placed propped fractures and the pressure variation with time in active field development on the stress-state redistribution. The main task of paper was to research the different parameters influence on stress state condition and especially on possibility of stress reorientation due to field development. In addition, the main purpose of the paper is to fiend impact of acting processes on hydraulic fracturing propagation. A finite element method was applied to calculate the stress state in a target sector of the oil field. All available seismic data and pertinent well logging data were used to update the geological and hydrodynamic models, and data from hydraulic fracturing, 1D geomechanical modeling, and drilling history were used for verification of the modeling results. In the following paper the reservoir parameters which can be useful for other fields of West Siberia were used. The 3D geomechanical model was created and used for the stress-state redistribution forecast, taking into account the field development history. The model was built by coupling the geomechanical finite element and compositional numerical reservoir simulator result at two time steps โthe initial, virgin state and the current state of the field development. It has been shown that the change in reservoir pressure has a significant influence on the value of the horizontal stress in the area of interest, whereas the change in stress orientation depends on the reservoir height, layout of wells, field development stage, and mechanical properties of the rock. Near the initial fractures, the fractures themselves have a strong influence on the magnitude and orientation of the horizontal stress.

Abstract Formation Pressure While Drilling tools were introduced to the industry several years ago (Pop, 2005). They have had widespread application and success especially in difficult offshore environemnts (Mishra, 2007) and very long horizontal sections (Larsen, 2008) but until recently they have been limited to high cost, deepwater environments. In many land environments Wireline Formation Tester (WFT) tools have often made more economic sense. In Russia FPWD tools have been run in the North Caspian and offshore Sakhalin both for drilling optimization (James, 2012) and for formation pressure guided well placement (Gupta, 2013) but had not ever been run on Land. In 2014, however a unique opportunity presented itself with very high angle wells drilled by Novatek in the field under Taz Bay. The wells being drilled had over 7000 m of vertical departure with deviation over 70 degrees. Additionally, since the field had been on production for some time, the wells were expected to encounter highly depleted sand layers. This implied highly unstable hole conditions and a significant risk of differential sticking. However, understanding the current reservoir pressure and therefore the amount of depletion was critical for managing the drilling hazards for this and future wells and for an accurate update of the hydrodynamic model. Given the risks associated with the hole instability a pipe-conveyed WFT was judged to be too risky and the FPWD tool was proposed. In this paper we will divide our presentation of this operation into three areas: conveyance and operational considerations, pretest design and execution and data analysis and integration

Abstract The article is based on experience of drilling record Senomanian ERD wells on Yurkharovskoe field from the bank of the Tazovskaya Guba towards offshore. Core problem happening while drilling such extended wells is wellbore instability happening in mudstone intervals when drilling close to the bedding. This article is devoted to study of the specific breakout mechanism in mudstone at shallow depth and finding the solution for well trajectory optimization to prevent wellbore instability. The main problem was solved in the work is optimization of shallow Senomanian wells trajectories via geomechanical modeling coupling with drilling experience which allow to find the solution and solve the instability problems while drilling. Drilling experinse of Senomanian wells was analized and used for geomechanical model verification and chose the best wells trajectories. Feature of mudstone collapse while drilling close to bedding at shallow depth was investigated, also termal expansion effect and its inpact on wellbore instability was evaluated. The result of the work was trajectories optimization and succesfull drilling of Senomanian wells on Yurkharovsko? field. Drilled wells have record horizontal displasement from vertical among all wells on YaNAO. The aggregate results of engineering calculations and obtained experience of Senomanian wells drilling have perspective opportunities of design and construction of such wells in YaNAO.
