If you talk to a typical subsurface professional working on unconventionals today (e.g., a reservoir engineer, completion engineer, geologist, petrophysicist, etc.) as I have in person and through media such as LinkedIn, you will find that many lament one key thing: Our sophisticated models have been reduced too much. Of course, I am generalizing and those are not the words they use; the lamentations come in many forms. The dissatisfaction with oversimplification is most easily observed as dis-taste for the type curve, the simplified model we use to predict upcoming new drills. (Yes, I know many of you will want to refer to them by their “proper” name: type well curve; I will be sticking with the colloquial version.) A simple meme posted on LinkedIn about type curves garnered one of the most engaged conversations I have seen amongst technical staff. The responses varied from something like “Thank God someone finally said this out loud” to comments such as “I don’t know anything better than type curves.” Most comments were closer to the former than the latter. What is even more remarkable is that our investors feel the same. In personal conversations, many of them refer to our type curves simply as “lies.” This perception, coupled with the historical lack of corporate returns, led investors away from our industry in droves. Many within the industry see it differently and want to blame the exodus on other factors such as oil and gas prices, climate change, competition from renewables, other environmental, social, and governance (ESG) issues, the pandemic, or OPEC’s unwillingness to “hold the bag” any longer. If you ask them, though, investors will tell you a simple answer: The unconventional business destroyed way too much capital and lied too much through the type curves. Why is it that both investors and technical staff are unhappy with our ability to accurately model future performance? Why can’t we deliver returns? The typical unconventional-focused oil and gas company has two models that are critical to the business. First is the subsurface model, with which we are all intimately familiar in its various forms, and the second is the corporate financial model, which is focused on cash flows, income, and assets/liabilities. It is unfortunate that the two models are separate. It means we must simplify one or both so they can communicate with each other. How can you observe this oversimplification while it is happening? It is happening when the finance staff say, “Please just give me a simple type curve and well count; I need to model, optimize, and account for debt/leverage, equity, and cash flows.” Meanwhile, the technical staff say, “Please just give me a CAPEX budget or a well count; I need to model, optimize, and account for well spacing, completion design, land constraints, and operational constraints.” Looking back, we know that the winner in this tug-of-war of competing needs was the type curve.

Subject. The article investigates key figures disclosed in consolidated cash flow statements of 25 leading publicly traded oil and gas companies from 2006 to 2018. Objectives. The focus is on determining the current level of values of the main components of consolidated statement of cash flows prepared by leading publicly traded oil and gas companies, identifying key trends within the studied period and factors that led to any transformation. Methods. The study draws on methods of comparative and financial-economic analysis, as well as generalization of materials of consolidated cash flow statements. Results. The comprehensive analysis of annual reports of 25 oil and gas companies enabled to determine changes in the key figures and their relation in the structure of consolidated cash flow statements in the public sector of the industry. It also established main factors that contributed to the changes. Conclusions. In the period under study, I revealed an increase in cash from operating activities; established that capital expenditures in the public sector of the industry show an overall upward trend and depend on the level of oil prices. The analysis demonstrated that even integrated companies’ upstream segment prevail in the capital expenditures structure. The study also unveiled an increase in dividend payments, which, most of the time, exceeded free cash flows thus increasing the debt burden.

Delta Mahakam is a giant hydrocarbon block which is comprised two oil fields and five gas fields. The giant block has been considered mature after production for more than 40 years. More than 2,000 wells have been drilled to optimize hydrocarbon recovery. From those wells, a huge amount of production data is available and documented in a well-structured manner. Gaining insight from this data is highly beneficial to understand fields behavior and their characteristics. The fields production characterization is analyzed with Production Type-Curve method. In this case, type curves were generated from production data ratio such as CGR, WGR and GOR to field recovery factor. Type curve is considered as a simple approach to find patterns and capture a helicopter view from a huge volume of production data. Utilization of business intelligence enables efficient data gathering from different data sources, data preparation and data visualization through dashboards. Each dashboard provides a different perspective which consists of field view, zone view, sector view and POD view. Dashboards allow users to perform comprehensive analysis in describing production behavior. Production type-curve analysis through dashboards show that fields in the Mahakam Delta can be grouped based on their production behavior and effectively provide global field understanding Discovery of production key information from proposed methods can be used as reference for prospective and existing fields development in the Mahakam Delta. This paper demonstrates an example of production type-curve as a simple yet efficient method in characterizing field production behaviors which is realized by a Business Intelligent application

Pressure communication between adjacent wells is frequently encountered in multi-stage hydraulic fractured shale gas reservoirs. An interference test is one of the most popular methods for testing the connectivity of a reservoir. Currently, there is no practical analysis model of an interference test for wells connected by large fractures. A one-dimensional equation of flow in porous media is established, and an analytical solution under the constant production rate is obtained using a similarity transformation. Based on this solution, the extremum equation of the interference test for wells connected by a large fracture is derived. The type-curve of pressure and the pressure derivative of an interference test of wells connected by a large fracture are plotted, and verified against interference test data. The extremum equation of wells connected by a large fracture differs from that for homogeneous reservoirs by a factor 2. Considering the difference of the flowing distance, it can be concluded that the pressure conductivity coefficient computed by the extremum equation of homogeneous reservoirs is accurate in the order of magnitude. On the double logarithmic type-curve, as time increases, the curves of pressure and the pressure derivative tend to be parallel straight lines with a slope of 0.5. When the crossflow of the reservoir matrix to the large fracture cannot be ignored, the slope of the parallel straight lines is 0.25. They are different from the type-curves of homogeneous and double porosity reservoirs. Therefore, the pressure derivative curve is proposed to diagnose the connection form of wells.

Summary Rate-time decline-curve analysis is the technique most extensively used by engineers in the evaluation of well performance, production forecasting, and prediction of original fluids in place. Results from this analysis have key implications for economic decisions surrounding asset acquisition and investment planning in hydrocarbon production. State-of-the-art natural gas decline-curve analysis heavily relies on the use of liquid (oil) type curves combined with the concepts of pseudopressure and pseudotime and/or empirical curve fitting of rate-time production data using the Arps hyperbolic decline model. In this study, we present the analytical decline equation that models production from gas wells producing at constant pressure under boundary-dominated flow (BDF) which neither employs empirical concepts from Arps decline models nor necessitates explicit calculations of pseudofunctions. New-generation analytical decline equations for BDF are presented for gas wells producing at (1) full production potential under true wide-open decline and (2) partial production potential under less than wide-open decline. The proposed analytical model enables the generation of type-curves for the analysis of natural gas reservoirs producing at constant pressure and under BDF for both full and partial production potential. A universal, single-line gas type curve is shown to be straightforwardly derived for any gas well producing at its full potential under radial BDF. The resulting type curves can be used to forecast boundary-dominated performance and predict original gas in place without (1) iterative procedures, (2) prior knowledge of reservoir storage properties or geological data, and (3) pseudopressure or pseudotime transformations of production data obtained in the field.


Subject US energy bond market. Significance The US benchmark, the West Texas Intermediate crude oil price, has slumped to 20-30 dollars per barrel in the second half of this month as the impacts of the COVID-19 outbreak have reduced demand and the breakdown of OPEC+ talks earlier this month increased supply. The price war between Saudi Arabia and Russia will exert great pressure on the oil and gas industry, which was already facing slower growth because businesses and the transport sector are reducing the carbon intensity of their activity. Impacts If US exploration and production firms cut investment, already distressed firms in ancillary areas such as oilfield services will suffer. Unemployment in the US shale industry could increase sharply. US oil and gas firms will try to protect their cash flows by, for example, selling assets, cutting dividends and raising fresh capital.

The article considers questions of introduction of modern instruments of management into practice of financial activity of the oil and gas company to optimize financial control. Characterisrtics of oil production markets and petroservices has been given. The results of the carried-out analysis revealed that for oil and gas branch of Kazakhstan at the moment the processes of restoration after the crisis of 2014-2015 are typical. The oil branch is important for economic development of Kazakhstan. Mangystaumunaygaz, JSC is one of the largest oil and gas extraction companies in Kazakhstan. The analysis of the key economic parameters of activity of Mangystaumunaygaz, JSC showed that for the observed period company developed successfully, despite the crisis phenomena in national economy. However, in the medium term there were observed fluctuations. For increase of efficiency of activity of the Mangystaumunaygaz, JSC company it is offered to introduce transformational financial model of management of assets based on modern instruments of management, such as: a system of separate account and a system of planning profit on strategic business units (budgeting), transition to the separate financial account of wells and their efficiency. It has been offered to apply one of means of coordination of commodity and financial streams - factoring. The main advantage of factoring consists in uninterrupted providing the oil and gas company with current assets right after delivery. In Kazakhstan operates the national factoring association, whose annual turn of participants in 2016 has made 28.1 billion tenges. The analysis of economic efficiency of factoring operation showed possibility of its influence on financial stability of the company.

Income approach based on the method of discounted cash flows (DCF) seems to be the main instrument to evaluate economic efficiency of investment projects when developing oil and gas fields. However, at early stages of exploration and exploitation of hydrocarbon resources, uncertainty and risks of investors are very high, which limits the use of traditional methods. It is necessary to develop valuation tools accounting high uncertainty of input data on the exploitation of oil and natural gas resources, flexibility of their development by formation of rational production strategy with volatility of the operating parameters such as the world oil prices and the size and value of oil and gas reserves. In this article presents the real options approach which accounts the potential of flexible and adaptive project management providing advantages in assessing development projects as compared to the traditional income methods. Implementation of this method is exemplified by the case of oil and gas fields in the east of the Siberian platform.

Abstract The financial model presented in the article attempts to further integrate capital budgeting into the firm's overall financial planning policy. Although it is an extension and generalization of Bernhard and Weingartner's previous models, it differs from these works by some basic assumptions related to both the objective function and constraint set. First, the objective function stresses the growing role of managerial discretion as opposed to the common assumption of maximizing shareholders' wealth. In particular we assume that managers wish to maximize the size of the firm under their control at the end of some future time horizon. Since net cash flows of the investment projects selected are sources of future investment funds, the managers try to keep the shareholders' dividends to a minimum level, sufficient enough however to pacify them. Secondly, the model constraints embody the complete set of financial instruments available to the corporation managers: in a sense, this enlarges the previous models' short-term external financing facilities by considering simultaneously the alternative long-term external financial instruments, namely equity and bond issues. In the latter case, the refunding features are incorporated in the constraints. The constraints also imply that managers prefer steady growth of net cash flows through time. This contrasts with the usual maximization approach which has been shown to favor long-term investment projects with somewhat more erratic net cash flows. The derivation of the Kuhn and Tucker conditions for the model allows us to show the impact of the opportunity cost of the various instruments on that of the liquidity requirement and the investment projects selection criterion. Finally, the duality properties also highlight the reciprocal relationships existing between the various opportunity costs, both internal and external.
