Mud Logging

Mud logging service provides engineering and technological support in the drilling process and formation evaluation. It includes the supply of drilling equipment with the complex of plugs and monitoring of drilling technological parameters, analysis of hydrocarbon composition of the air-gas mixture (gas logging), lithologic and geological formation evaluation, as well as geological-technological consulting support to optimize the drilling process and prevent accidents.

The service is provided in the partnership with company Drill-Lab Sp. z o.o. (Poland), which has many years of experience providing mud logging service on the five continents for the biggest world oil and gas companies both offshore and onshore.

We reliably and securely collect and analyze real-time geological-geochemical, geophysic and technological information to perform well condition control at all stages of its construction and putting into the production in order to improve the quality of drilling, reduction of well construction term and effective disclosure reservoir horizons.

Based on the continuous monitoring of the drilling process and maintaining the stability of wellbore, we provide latest update regarding the situation, processed for making informed decisions that guarantee safe, efficient and accident-free of works performance.

This information will simplify the process of formation evaluation and identify ways to support stability of wellbore and avoid complications during drilling. The main purpose of the service is predicting possible problems at all stages of the well construction before they occur.

Thanks to the control of the drilling teams’ quality and strict compliance with the parameters of the drilling project, GTP and technological orders, as well as the optimization of drilling practices, provided the reduction of technological risks, non-productive time and cost the well construction.

We also monitor the settings and level of mud fluid in the well and circulation system to ensure well blowout safety as in the process of drilling, and at the time of RIH/POOH 

Our Mud Logging Unit acts as the operational Center for the collection, processing and transmission of information on the rigsite, including data collection from LWD, MWD services, cementing and others.

The collecting and processing information system allows you to allocate and distribute important information on-line to all the participants of the drilling process both on the rigsite and remotely at the location specified by the Customer.

The Service may include technological support from the experienced production engineers and geologists, who will provide the Customer an exact and accurate picture of what is happening on the well, based on the analysis of the data file of all processes and services involved in the drilling process.

Services are provided in accordance with the requirements of the state standards and internal instructions of the Customer and the best international practices with reporting in three languages.
