GM Uganda paves the way for Tilenga oil production

GEOMECHANICS UGANDA PAVES THE WAY FOR TILENGA OIL PRODUCTION WITH CRITICAL GEOTECHNICAL INVESTIGATIONS
Kampala, Uganda – Geomechanics Uganda recently completed a vital five-month project undertaking comprehensive geotechnical surveys across 31 Tilenga production well pads in Uganda's oil-rich Albertine region. This crucial investigation, commissioned by Mota Engil on behalf of Total Energies, marks a significant step forward in the construction of production wells, aligning with the Ugandan government's ambitious plans to unlock the nation's oil and gas potential. The extensive scope of work entrusted to Geomechanics Uganda involved a multi-faceted approach to gather essential subsurface data.

This included:
  • Geotechnical Drilling: Utilising the wireline method, boreholes were drilled on all 31 well pads, each reaching a depth of 30.0 meters.
  • Trial Pits and In-situ Testing: Within each well pad, three trial pits were excavated to facilitate in-situ tests, including Dynamic Probing Light (DPL) probes and infiltration tests conducted using the double-ring method.
  • Cone Penetration Testing (CPTu): CPTu tests were performed on each well pad, targeting a depth of 20 meters or refusal, to provide detailed soil stratification and engineering properties.
While the project ultimately proved successful, it was not without its hurdles. The primary challenge encountered by Geomechanics Uganda was land acquisition. Delays in securing access to various well pads impacted the project timeline. In one particularly acute instance, a landowner granted access for a mere three days, demanding that drilling and demobilisation be completed within this time. Thanks to the efficiency of the Uganda team, they were able to successfully navigate this challenge.

Despite these logistical difficulties, Geomechanics Uganda maintained an exemplary safety record. The project was completed with full compliance with stringent oil and gas site Health, Safety, and Environment (HSE) requirements, resulting in zero incidents throughout the entire five-month duration. This commitment to safety underscores the professionalism and dedication of the Geomechanics Uganda team.

The comprehensive geotechnical investigations conducted by Geomechanics Uganda were instrumental in the subsequent phases of the Tilenga project. The wealth of data collected directly informed the successful structural and civil engineering design of the foundations for the Tilenga well pads and their associated access structures. This foundational work is critical for ensuring the stability and longevity of the infrastructure required for oil and gas extraction in the region.

The completion of these vital geotechnical surveys by Geomechanics Uganda represents a key milestone in the development of Uganda's oil and gas industry, setting the stage for the efficient and safe construction of the Tilenga production wells and contributing to the nation's economic growth.
