We invite you to SPE young professionals meeting on "Shale volume, porosity and translation problems".

To increase the efficiency of field development, more and more wells are drilled with horizontal or high angle section at the end (HAHZ). Despite this, well logging data analysis is based on methodic and models developed using data from vertical and slant wells with relatively low inclination angle. Although it works well for vertical wells, it does not take into account geometric effects associated with high angle of drilling where wells are drilled almost parallel to formation layers. That often leads ambiguities while logging data analysis and formation evaluation in HAHZ wells compared to low angle wells. This fact does not allow using logging data from horizontal wells for geological and hydrodynamic models, which reduces its credibility.

The presentation describes uncertainties that exist when using conventional processing and interpretation techniques in horizontal wells and their causes. For demonstration purpose, the paper uses an example from real well, which has been drilled horizontally in complex environment in one of the field of Western Siberia region of Russia.

Azimuthal measurements application together with advanced modeling software packages enable more reliable estimation of well length exposed to reservoir, spatial position of its boundaries and essential reservoir properties, such as porosity and saturation. As a result, the geological model may be refined locally.

We invite you to SPE young professionals meeting on "Inversion and Machine Learning in Well Logging data Interpretation".

With the increasing importance of the cost of projects FPP stage to minimize the geological and technical risks associated with the full-scale development of deposits only increases. An integrated approach multidisciplinary group based on detailed modeling to study the formations fluids and potential wells at the stage of FPP, based on the disparate and often conflicting data, allows you to develop metrology and other requirements for conducting research to develop an optimal design, successfully conduct himself step FPP narrow source uncertainty range and improve the expected development indicators.

For reliable identification of the parameters of the object (deposit, field) at the stage of field pilot projects (hereinafter - FPP) are equally needed at least two components - the information content measurement system response and detailed modeling of planned processes of the FPP. This makes it possible not only to create a design study, but further optimization FPP plans, with no loss of accuracy or completeness of the expected results. The results of the implementation of this approach for one of the Arctic projects (complex hydrodynamic studies of wells - well testing, including Interference) are interested.

Based on the detailed geological and hydrodynamic modeling of the FPP well tests, the sensitivity of the production parameters to the base reservoir and fluid properties is estimated. Consideration of a wide range of uncertainties related to the sedimentation, the facial structure of the reservoir, development parameters, technological and infrastructure constraints, makes it possible to rank the most important uncertainties and to correct the FPP if necessary.

Detailed simulation in this case gives a numerical evaluation of the expected program results (for example, variations of bottomhole pressure responses to the initial perturbations of the main parameters, the duration of well tests etc.). This approach provides a wide opportunity for developing metrological requirements, as well as an appropriate well test plan and a well test design with a minimum risk of loss of data quality.

The choice of the optimal development method for low permeability reservoirs has been a major challenge for most oil companies in recent years. 

We invite you to SPE young professionals meeting on "Optimization of reservoir pressure monitoring".

Gazprom Neft target oriented production is 100 million tons/year. This can be achieved through the commissioning of new assets.

The current economic situation, as well as the lack of highly profitable reserves, make more attention to new investment projects. It is necessary to estimate correctly the costs of developing new assets to make the right management and technical decisions in order to maximize the effect of invested funds, involving low-margin and hard-to-recover reserves.

 

Goals and targets

Cost engineering aims to improve the consistency of capital and operating cost evaluation at the early stages of project implementation.

1.     Make checklist of existing methods and different software of cost evaluation at the early stages of project implementation.

2.     Define ways how to improve the consistency of capital and operating cost evaluation

3.     Create the “Cost model” bringing together the opportunity to evaluate capital and operating costs in order to make comprehensive cost assessment.

4.     Achieve high level of automation - implement cost engineering tools on special IT platform

 

Cost models

The analysis of cost software show that existing cost software do not provide the necessary level of accuracy. The cost software has been developed in Gazprom Neft since 2014.

 

Results and conclusion

The developing tools of the capital and operating costs assessment do not have analogues in Russia. Today company Gazprom Neft develops first-of kind software in the oil and gas industry. The first results of utilizing cost tools show the need of total costs analysis for making effective business decisions during the project life. As a result every correct solution from the issue based on the comprehensive cost assessment help to achieve the company strategic goal to produce one hundred million tons of oil.

 

The most important results are:

1.      The software analysis of cost engineering tools was carried out.  There are no special costs tools for detailed calculation.

2.      It was decided to develop their own costs tools based on the decomposing method. This method improves the quality of costs calculations.

3.      The capital expenditures’ assessment tool is developed and used during the concept design.

4.      The operating expenditures’ assessment tool is developed too with detailed cost units.

5.      The potential effect of utilizing these tools can achieve more than 1.5 billion of rubles just from.

1.        6.         In the near future costs tools will be realized on the special IT platform which gives opportunity to improve the accuracy of costs assessment.
