The paper shows the development of technogenic axial loads acting on the column of casing pipes during the construction of directional wells. Axial loads depend on the angle of inclination of the wellbore trajectory and its length in the productive deposit, as well as from the timing of the input of the inclined-directed section of the trunk from the beginning of the development of the field.

Deformation Processes

The analysis of works on identification of causes of deformation of casing production strings of wells is carried out. The main reason for the deformation of the strings is the technogenic deformation of the rocks of the layers of drained deposits. The need to take into account technogenic processes for the design of used wells at the design stage of oil and gas field development is shown.

The characteristics of good energy company borrowers are strong management, integrity, diversification, flexibility, a sound financial basis and business acumen. Acceptable reasons for borrowing include requirements for working capital, plant expansion, modernisation, oil and gas field development and the manufacturing of oil tools and related products. Security for loans is based on the company's reserves, the duration of the debt and priority over other indebtedness. Most loans are evaluated on the grounds of general corporate credit, that is, the overall credit standing of the borrower.

Abstract The steel lazy wave riser has been used in deep-water oil and gas field development because it has good adaption to the movement of the upper platform and economic efficiency. The typical design criterion and design flow of steel lazy wave riser are introduced in this paper. The design method and the equivalence principle of distributed buoyancy modules are given. The formulas of equivalent hydrodynamic parameters are derived in this paper. The influences of distributed buoyancy modules (DBM) and the buoyancy factor on the configuration of the riser, the top tension, and the bending moment distribution are discussed and summarized. The distribution law of effective stress response along the pipe can be analyzed by dynamic analysis, and it provides reference for the global design of steel lazy wave riser.
