Drilling Time

Three horizontal wells with horizontal sections of up to 331 m were drilled successfully during the development of the marginal North Herald and South Pepper oil and gas fields, which have relatively thin oil columns (6 to 12 m) at a depth of some 1200 m sub-sea. A steerable motor system was used to maintain directional control within the design parameters. This system proved to be successful from the start and no major changes to the bottom hole assembly design were required to drill all the wells. Average drilling time including running and setting the seven inch liner amounted to 12 days. The wells were tested with rates up to 7500 BOPD through a one inch choke.

Steering Force

Deep space drilling is necessary for appropriate chemical and biological sampling for subsurface exploration. The Robotic Planetary Drilling System (RPDS), which is currently being developed by our team, is designed to be a compact self-propelled, steerable electromechanical drilling system that can penetrate into large depths in planetary bodies. In this paper we present the detailed innovative mechanical design of the RPDS. Its main components are: a) the drill bit/cuttings bucket, b) the rotary propulsion unit including novel three 3-degree of freedom (DOF) propulsion actuators, c) the power/control module, d) the non-rotating steering unit including three 1-DOF steering actuators and e) the communication module. Three 3-DOF propulsion actuators uniformly distributed around the rotary propulsion unit impart rotating, linear motion to the drilling bit, while another three 1-DOF steering actuators provide the steering force for automatic directional control. The RPDS is propelled in the manner of a turning screw, which offers simpler kinematics structure, higher efficiency and thus, potential for miniaturization and deep drilling. The mathematical modeling and analysis of the RPDS that were conducted to evaluate its performance are also being presented in this paper.

The article is devoted to the issue of optimizing the development system and increasing the efficiency of carbonate deposits of the Tournaisian stage of the Chetyrmanskoye field developing, and the formation of a strategy for their additional development. As a result of the horizontal drilling, the rate of withdrawal from current recoverable reserves in the main area in terms of reserves increased from 0.3 to 5%, which confirms the high efficiency of horizontal wells drilling with multi-stage hydraulic fracturing in reservoirs with high stratification and heterogeneity degree of the productive section in order to increase the rate of reserves production and achieve the approved oil recovery factor, as well as the high efficiency of the proposed methodological approach in the design of the facility development by a system of horizontal wells, the correct choice of the facility development strategy in the design solutions formation. Keywords: oil fields development; carbonate deposits; development of reserves; multi-stage hydraulic fracturing; horizontal well.
