Effectiveness of gas inflow stimulation works at t

4. RESULTS AND DISCUSSION 
 
An important indicator of drilling operations for gas inflow stimulation is their effectiveness, which is a 
multifaceted indicator representing an integral assessment that includes: resultativeness, cost-effectiveness, 
efficiency, quality (of management, the technical and technological process of work performance, working 
conditions, etc.), productivity, innovativeness, balance of the interests of key groups interested in drilling 
operations for gas inflow stimulation, etc. (Barbe, 1983; Emmanuel, Ranney, 1981; Ertekin, Adewumi, 
1995). 
There are several primary approaches to the definition of work performance effectiveness: 
- as the degree of attainment of the purpose of these works, in which it is vital to recognize their dynamism 
and a clear distinction between the official goals of the organization and the operational goals of drilling 
operations themselves. This approach is advisable when the established goals are specific and measurable 
and cover a wide range of the company’s operations; 
- as the ability to use all the internal and external environments to find rare resources used in the operations. 
One of the main aspects of this approach is interdependence between the drilling enterprise and its external 
environment in the form of the exchange of certain resources, goods, and products. In contrast to the 
requirement of maximization posed by other approaches, this method suggests optimization of the use of 
the environment; 
- as the ability to achieve maximum results in drilling operations with fixed costs or the ability to reduce 
costs while obtaining the required results; 
- as the ability to achieve the goals based on reasonable internal characteristics because the correctly chosen 
gas inflow stimulation drilling technology and technique increase satisfaction and a sense of security and 
control; 
- as the level of satisfaction of the customers of drilling services, i.e. the gas producer. This approach is 
applied in cases when there are certain groups of stakeholders outside of the drilling organization who are, 
nevertheless, able to exert significant influence on its functioning.

According to a prominent researcher in the field of management, P. Drucker, “effectiveness results from 
doing the right things”. Essentially, effectiveness applies primarily to attaining the goals of the organization, 
it reflects the quality of the drilling works, and major importance is attributed to proper goal-setting. 
A. Feigenbaum believes that the formation of the category of effectiveness is associated with the logic of 
the conceptual sequence: need – goal – end result. In this case, the goal as an element of management reality 
is determined by the needs of stakeholders. The end result takes the form of satisfaction of a certain need 
on which the system is focused. 
F. M. Rusinov associates effectiveness with the implementation of management objectives and the 
performance of the managed object for a certain period. Thus, the goal to implementation of which is 
assessed can be compared with the end result – the product and the degree to which it satisfies the social 
needs of society. End results as an economic category have to be expressed in a system of indicators that 
reflect their quantity and quality. 
N.V. Tereshchenko and N.S Iashin (2016) argue that effectiveness characterizes the level of goal 
achievement, as a condition for the organization to achieve the necessary results. 
Based on the proposed provisions, we can formulate the following definition: effectiveness is assessed as 
the degree of attainment of the results of drilling operations adequate to the established and intended goals 
(gas inflow stimulation) that meet the needs of stakeholders (customers and the drilling enterprise) and 
creates conditions for the constant development of the drilling organization. 
Proceeding from the above provisions as initial data, we can conclude that the performance of operations 
can be effective if the following conditions are satisfied: 
- the goals are viewed as temporary, derived from the requirements imposed by both the drilling customer 
and the drilling organization; 
- the content of the goals corresponds to the characteristics of the drilling organization and reflects the 
internal and external conditions of its functioning; 
- the set goals are successfully achieved and justify the resources spent; the required cost-benefit ratio is 
met; 
- the goals are attained by the accepted and universally approved means of the enterprise; the need for this 
condition is determined by the socio-economic environment of the drilling organization, and its satisfaction 
prevents additional costs brought by social conflicts that may arise at the enterprise (Koontz, O’Donnell, 
2014; Merkushova, 2011; Sazhin, Pletneva, 2014). 
There are three blocks of factors that affect the effectiveness of work performance. The first block consists 
of systemwide factors that determine the prerequisites for the efficient operation of the drilling enterprise: 
- the degree of implementation of the principles of work of drilling organizations; 
- organizational culture formed and developing at the drilling enterprise; 
- the system of selection and evaluation of managerial decisions made by the organization’s executives with 
respect to the execution of drilling operations and the choice of the gas inflow stimulation method;

- the organizational mechanism that provides coordination and interconnection of technical and 
technological processes as part of gas inflow stimulation. 
The second block covers external factors that limit the activities of the drilling organization and are caused 
by communication patterns, the key among which are the requirements of the external environment (the 
state and the region) and the constraints of investment resources; 
The third block includes the factors of development management of the drilling organization, the presence 
of prospective programs of drilling operations, and provision with resources. 
In terms of the significance and impact of particular factors, it is necessary to distinguish those that exert 
the strongest influence on the effectiveness of gas inflow stimulation drilling (Skripko, 2013; Stepanov, 
2012). 
For an organization providing drilling services to be successful for a long period of time and successfully 
achieve its goals, the organization needs to be both efficient and effective (Shvets, 2014). 
According to P. Drucker, effectiveness is the result of “doing the right things”, while efficiency comes from 
“these things being done right”. 
Efficiency in general should be presented through relation and comparison. Efficiency is the relation of 
some effect (result) to the costs of its attainment. For example, the value of an indicator has to be compared 
to either some ideal value or to the level achieved by organizations previously (Vaganov et al., 2017). Here 
it is crucial to distinguish between cost-effectiveness and efficiency. The fact that the amount of resources 
spent was less or more than planned does not indicate effectiveness. 
The present study investigated the terminological foundations for the assessment of the effectiveness of gas 
inflow stimulation drilling operations and considered the main approaches to effectiveness assessment. 
Analysis of the approach showed that the most acceptable and appropriate for today's practice and for 
successful work are the system and process approaches, which allow organizing the work as a continuous 
chain of structural and logical stages affecting the processes of substantiating the feasibility of inflow 
stimulation by implementing sequential, logically interrelated stages. 
The paper provides a classification and analysis of the most prominent Russian and foreign methods and 
identifies the problems that arise in assessing the effectiveness of gas inflow stimulation operations at the 
final stage of field development. The existing definitions of effectiveness give reason to conclude that the 
effectiveness assessment method allows for a broader consideration of the entire variety of factors, goals, 
and economic results, which demonstrates the particular importance of effectiveness assessment. 
The conducted analysis of the current state of scientific and methodological support for the functioning of 
an organization reveals the lack of an accessible scientifically grounded method for assessing the 
effectiveness of performed works that would be adapted to the real conditions of scientific organizations 
and rely on the fundamental principles of classic management on the one hand and modern information 
technology on the other. 
We propose a comprehensive approach to the assessment of gas inflow stimulation operations that delivers 
interrelated effectiveness assessments. The described effectiveness assessment method assumes the 
following sequence of key stages: classification and ranking of processes; formation of the set of 
performance indicators and their ranking by significance; comparison of the current value of indicators with 
their normative values; point scoring of each indicator; calculation of the effectiveness of processes and 
group of processes; and calculation of the integral indicator of the organization’s effectiveness.
