Integrated Project Management

Endevour is one of a few companies on the Ukrainian market, which has experience of integrated project management of drilling oil and gas wells.

Integrated project management (IPM) is the process of managing the well construction or workover with engineering and technical guidance to ensure the quality of work, prevent accidents and complications, provide adherence to the QHSE rules, in accordance with Customer’s budget and deadlines.

We have the experience of providing IPM and supervising services in accordance with international standards during drilling wells of more than 6000 meters depth and with complex geological conditions. Professional engineering team has a solid practical experience on projects in Ukraine, Kazakhstan, Uzbekistan, Russia, Turkmenistan, and work with the leading global drilling and service companies.

Project management ensures the integration of advanced technologies and services, implementing the best world practices and bringing additional expertise in engineering, drilling, geology and process management, as well as a combination of work experience at a local market with the world-class technologies.

We consider Customer’s requirements and analyze the potential complications and risks, ensuring achievement of the goals with the highest economic efficiency, through geological expertise, engineering management, procurement, logistics and the interaction of all process participants, supervising the job performance and monitoring the compliance with regulations.

Realizing how unique and complex your project is, the interaction of all the participants is planned to ensure predictable and economical project result through the highest quality and efficiency of processes, not only on the construction stage, but also throughout the well lifecycle.

All the works are performed with the definitive compliance to QHSE rules.

IPM services are provided on the basis of individual contracts which provide optimal schemes of cooperation among all parties. The best result is achieved with the complete project lifecycle management, but IPM contracts may include various schemes of responsibility and power distribution of the managing company, the Customer and all other participants of the process. Endevour can provide services in any combination – from the development of pre-project solutions to supervising of the well construction process and complete project management. We offer options of the full support of project implementation as well as updating and strengthening of the Customer’s team where it is needed.

One of the IPM components which often acts as a separate service, is the supervising while drilling. Third-party supervising provides reliable control of all types of work on the wellsite, and coordination of all participants of drilling or workover to prevent complications and reduce risks while drilling, including the processing the technological and economic data, cost control, amendments to the work programs, operational and analytical reporting.

The experience gained by the Endevour’s engineers allows you to comprehensively assess the emergency situation, choose the technology of breakdown elimination and pick up the necessary fishing and other tools to organize the process of fishing job accurately.

Leak repair

As an exclusive representative, Endevour offers a leak repair service from Seal-Tite® International company based on a unique pressure activated sealant technology. The sealants are unique in that the pressure drop through the leak site causes the sealants to polymerize into a flexible solid. Only at this point of differential pressure will the sealant polymerization process occur. As the reaction proceeds polymerized sealant forms at the edges of the leak site and

simultaneously links together to form a flexible bond across the leak site. The remainder of the sealant is the system remains liquid.

A Seal-Tite® Technician is required on location to diagnose and cure leaks following the procedures developed for the application. If after diagnostics we determine that the leak severity is beyond our capabilities, he will not attempt to cure the leak.

We do not take on jobs unless we are confident we can cure the leak or the customer instructs us to try even though the chance of success is low.

Seal-Tite® sealants can be used in the harshest operational environments and will maintain their sealing integrity up to 500º F and to 22,000 psi. You can depend on it for high pressure leak repair jobs.

Sealants compatible with oil or water/glycol-based hydraulic fluids are designed to solidify only at the high point of differential pressure, so only the leak is sealed. Any excess sealant remains inert, in a liquid form, and will not clog the hydraulic system or other equipment.

The typical applications are:

  • Surface Leaks (Pipeline Pinholes & Weld Defects, Flange Connections, Ball & Gate Valves)
  • Wellhead Leaks (Ring Gaskets, Gate Valves & Actuators, Tubing & Casing Hangers)
  • Cement Leaks (Microannulus, P & A Cement)
  • Cavern Casing Shoes
  • Downhole Leaks (P & T Guage Mandrels, Sliding Sleeves, Seal Units & Packers, Tubing & Casing, Liner Hangers, Tie Back Assemblies)

The characteristics of the pressure-activated sealants allow for flexible delivery methods. Since the sealant remains liquid except in the presence of differential pressure, there is little concern for the time to deliver the sealant to the leak site or the pressure and temperature (below 500 °F) of the well.

Common sealant delivery methods for onshore wells include:

  • Pump down tubing
  • Pump down casing
  • Spot with wireline dump bailer
  • Spot with coiled tubing
  • Atomize into gas stream

We have 87% of successful jobs among total number of jobs when sealant was pumped.

Features and Benefits

  • Liquid sealant
  • Pressure activated
  • Polymerizes into a flexible solid
  • Solidifies only at the leak site
  • Tested to 22,000 psi and 500˚F
  • Excess sealant remains a liquid
