- assessment of the effectiveness of drilling processes and hydrocarbon inflow stimulation;
- assessment of the functioning of selected objects which the organization considers important in the process
of drilling and hydrocarbon inflow stimulation;
- analysis of the work of the structural division that performs the drilling;
- analysis of compliance with the items of the standard containing requirements for drilling works at the
enterprise;
- information about the results of the internal audit of drilling works.
The general approach to developing a methodology for quantifying the effectiveness of drilling operations
can be presented as follows:
- the assessment of drilling effectiveness is expressed by a coefficient (from 1 to 100 or from 0 to 1);
- the coefficient is comprised of the sum of criterion scores, which are ranked and have a weighting factor;
- the criteria are decided by a group of experts from among the drilling enterprise’s employees and external
experts relying on their knowledge of drilling operations and hydrocarbon inflow stimulation;
- the assessment is presented both as an absolute value and in relation to the ideal values of the coefficients
(criteria) or the base value (for some period).
Assessment of the effectiveness of drilling operations requires the following conditions to be met:
- executive discipline of evaluators;
- involvement of the highest possible number of employees in the assessment of drilling effectiveness;
- detailization of the goals of the drilling organization up to the level of technological processes and
performers;
- clear criteria for the assessment of drilling effectiveness shared by all performers;
- an established understandable algorithm for self-assessment;
- standard forms and templates for reporting on the results of drilling operations.
