28th February - 3rd March, 2025

Itinerary

The EAPCE’25 Pre-Conference field excursion is a 4-day trip from 28th February to 3rd March 2025. The trip will provide an opportunity to understand the structural and stratigraphic framework of the northern part of the Selous failed rift basin, with some insights into Kilosa Kilombero and Ruvu basin along the way.

Delegates will witness incredible geological features that characterize the hydrocarbon potential of the Selous Basin, including the potential source, reservoirs and seal rocks of the Karoo Formation. At the same time, they will also see the attractiveness of the Nyerere National Park (formerly Selous Game Reserve), including its diverse wildlife, grasslands and tree species located in the basin and visit the Mwalimu Nyerere Hydroelectric Power project.

Along the way, delegates will make a few stops to appreciate the well-exposed sections of Cretaceous and Jurassic sediments that mark the main targets for hydrocarbon generation and accumulation in the Ruvu Basin and will also visit a viewpoint to enjoy the magnificent scene of the Kilosa Kilombero basin that constitutes potential elements for the oil discovery in the basin.

DAY 1: 28TH FEBRUARY 2025 - DAR ES SALAAM TO KILOSA SUB BASIN VIA MOROGORO


The trip from Dar es Salaam to Kilosa via Morogoro Town, will take you through Neogene sediments in Dar es Salaam and magnificent exposure of Jurassic sediments at Msolwa quarry and a good look at the Jurassic Sediments-Basement rocks contact at Msolwa bridge area.

Thereafter, delegates will have the opportunity to admire the gorgeous scenery of the Uluguru mountain chains of the Mozambique Orogenic Belt when driving to Morogoro town.

Further, at Kilengezi village the delegates will observe good exposure of Permian to Triassic tillites which indicates the occurrence of glacial period during that time.

Along the road to Kilosa town, Delegates will witness the beautiful lowland swampy, flatland and wetland of the Kilosa sub-basin which is part of the Kilosa Kilombero Basin. At Kilosa Town delegates will be able to view the beautiful scenery of the Sagara Mountains and briefly learn the geological features that characterize the basin and its potential for Oil discovery. The Sagara Mountains form the western boundary of the Kilosa Rift, the Sagara mountains formed by large-scale blocking faulting and tilting of Kilosa rifting system. The flating alluvial marshland of the Kilosa Valley are the down-thrown block of the rifting.

Later, the delegates will drive back to Morogoro town for a night stay at the foot of the Uluguru Mountain in Nashera Hotel.

 

DAY 2: 1st MARCH, 2025 - MOROGORO TO SELOUS BASIN VIA KISAKI TOWN

Along the way Delegates will make a stop at Changa village, and delegates will observe good-quality white marble at an abandoned marble mine.

Delegates will stop at Chamanyani Hill (Msonge Village) to view the First glimpse of the Selous basin as approaching from the North. While driving down to the basin the delegates will view the Basement to Karoo sediment contact on the road cut. The Selous Basin which is underplayed by Karoo sediments is known by the presence of potential elements for hydrocarbon exploration.

The outcrops seen: Metamorphosed dolomitic marbles observed in abandoned mine at Changa Village. The marbles are extensively distributed and well exposed in this area.

 

Further, at Kilengezi village the delegates will observe good exposure of Permian to Triassic tillites which indicates the occurrence of a glacial period during that time and marks the syrift sediments of the basin.

 

Tillites exposed at Kilengezi village consisting of unsorted large boulders of basement (marble, gneiss and quartzite), sub rounded to rounded pebbles and cobbles deposited by melting glacial and then transported and deposited by river formed after melting of ice.

 

Then delegates will drive to Sable Mountain Lodge in the Kisaki area for the night stay.

 

DAY 3: 2ND MARCH, 2025: SABLE MOUNTAIN LODGE TO MARAMBWE GATE AND TAGALALA HOTSPRING

The delegates will drive to Matambwe Gate to enter Nyerere National Park. While touring the game reserve the delegates will have an opportunity to observe key petroleum elements of the basin including Karoo shales and intercalation of siltstone and coarse-grained sandstone at Fuga Hill and Kidahi road cut respectively.

1st - 3rd March, 2025

ITINERARY

A three (3) days pre-conference field excursion to the central and northern part of the Albertine graben is planned to provide an opportunity to the delegates to observe the geology of these areas, discoveries, developments in the Industrial Park including the International Airport and field developments and tour the famous Murchison Falls National Park.

 

DAY 1:  KABALENGA INDUSTRIAL PARK, KAISO-TONA GEOLOGY AND KINGFISHER DEVELOPMENT PROJECT

Delegates will leave Entebbe for Hoima City located in the Central part of the Albertine Graben. The first day will be spent in the Kaiso-Tonya area. Kaiso-Tonya lies in a faulted large-scale relay ramp (synthetic transfer zone) formed by overlapping synthetic boundary faults controlling the southern and northern Lake Albert depocenters. The area at the same time is an accommodation zone. Between these two major faults lies other three sets of faults that have accommodated the associated stresses trending E-W, NE-SW and in the N-S directions. Kaiso-Tonya geology has been divided into four Formations namely; Nkondo, Warwire, Sebugoro and Kaiso.


Stop 1: will be made at Kabaale Industrial Park to discuss the refinery and basin wide developments of the discovered resources in Albertine graben, and the progress of the Kabalega International Airport

Stop 2 & 3: will be made in the Nzizi and Mputa fields in Kaiso-Tonya. Mputa discovery is important to the Albertine Graben and the EARS as it was the first commercial oil discovery in East Africa.

Stops 4: Kingfisher Development Project and support Infrastructure development to understand the progress and journey to First Oil.
The delegates will head to Hoima City and spend the night.

DAY 2: BULIISA-WANSEKO GEOLOGY AND DISCOVERIES

 

Stops 1–2 Petroleum exploration operations in Butiaba-Wanseko area

Stop 1: The team will drive from Hoima City and make a stopover at the top of the escarpment to study the geometry of Northern Lake Albert basin, view the Waki dome and its associated rift margin prospects.

Stop 2: A stop at one of the well pads in Gunya Field and the Industrial Area within the Tilenga Project to understand the progress towards the First oil.

Stop 3: Boat ride on the Victoria Nile

The delegates will head to Hoima town and spend the night.

Participants will take a boat ride in the late afternoon on the Victoria Nile to see the Paraa seep and the bottom of Murchison falls. From the boat, reservoir quality sandstone exposures will be seen along the riverbanks and the Paraa oil seep on the surface of Victoria Nile.

From geochemical studies, the Paraa oil seep is a Type-1, mid-mature, lacustrine source. The manifestation of hydrocarbons on the surface (on Victoria Nile) confirms the presence of a mature source rock, which has generated and expelled oil.
