Miek Meyering has over 40 years of experience in geological consulting and mining, including currently working as an Associate Geological Consultant for CSA Global (UK) Ltd where he manages resource drilling projects and provides technical advice. Prior to this he held senior geological roles for several mining companies such as Uranium One, Anglogold Ashanti, and Iscor, where he was responsible for exploration, mine geology, managing teams, and technical reporting. The resume outlines his extensive experience in core logging, sampling, data analysis, project management, and training junior staff across open pit and underground mining operations for gold, uranium, chrome and other
Many details go into the planning of a mine. The information gathered must come from several
sources. First is the geological, structural, and mineralogical information, combined with the
resource/reserve data. This information leads to the preliminary selection of a potential mining method
and sizing of the mine production. From this the development planning is done, the equipment
selection is made, and the mine workforce projections are completed, all leading to the economic
analysis associated with mine planning.
The Tampia Hill gold deposit, is located near the town of Narembeen in the Wheatbelt of Western Australia, 25 km east of Perth. Explaurum held the project from 2014 until the end of 2018 and during this period Kenex provided key services including on-site project management, interpretation of downhole wireline data, building 2D and 3D geological maps, and 3D mineral potential mapping for resource domaining and to help target grade control drilling inside the pit design. Kenex were also involved in the compilation of data over the wider area around Tampia and helping to target exploration using updated geological maps and mineral potential mapping.
Methods and stages of Mineral Exploration: Adaptive Resource Management PlanNgatcha Bryan
Exploration can be divided into a number of interlinked and sequential stages which involve increasing
expenditure and decreasing risk. Early stages of exploration are planning and prospecting. The planning
stage covers the selection of commodity, type of deposit, exploration methods, and the seĴing up of an
exploration entity. Prospecting covers activities leading to the selection of an area for detailed ground
work; this is the point at which land is acquired. The subsequent stages involve targeted prospecting and
exploration in order to quantify and qualify the mineral resources. Pre-feasibility study is then
performed for evaluating the commercial viability of the deposit (Adapted from Moon et al., 2006).

Acordionero Oil Field Discovery, Middle Magdalena Basin, Colombia: An Unusual...Mario Prince
Oil exploration of Cenozoic clastic reservoirs in northern Middle Magdalena Basin has been predominantly focused on faulted anticline-type structural plays rather than more subtle stratigraphic or combination traps. The Acordionero field is a recent oil discovery found within an unusual structural -stratigraphic configuration, defined only after 3D and 2D seismic reprocessing benefitting from well results.
Based on a trap outline originally mapped with 2D seismic lines, the Acordionero-1 well was located and drilled in 2013 between two 1960s abandoned dry wells. The true trap configuration delineated by reprocessed seismic data was confirmed by follow-up 2014 drilling. In order to understand the field, multidisciplinary studies were conducted including detailed geology study of the Lisama Formation using outcrop and core data, reprocessing and interpretation of seismic data with constraining geological input, detailed log analysis and exhaustive reservoir examination from test and flow data.
The field is an important accumulation in the Paleocene sandstones of the Lisama Formation and has estimated original oil in place of more than 300 million barrels. Remarkably, the oil gravity for the field ranges from 13.5 to 25º API. The production rates are also atypical for the basin; the initial test for the well Acordionero 1 produced over 3200 BOPD in natural flow. This case history perfectly illustrates the concept of holistic approach to petroleum exploration that includes geology, geophysics and engineering contributions in all phases of the project (Enachescu, 2015). This integrated process is extended to field reservoir evaluation and design of production rate and optimum recovery plan.
Evidence of Geological Control on Reservoir Petrophysical Properties of “Beta...Premier Publishers
Geological controls on the reservoir petrophysical properties of “BETA Field” have been carried out using suites of wireline logs. Stratigraphic relationship among the reservoir sand bodies including their geometrical architectures, and their stacking patterns were also established. Exponential regression analysis of some of the petrophysical parameters were carried out to establish any relationship with depositional processes as well as depositional environments of the reservoir sand bodies in the field. The main factor controlling petrophysical properties and thickness for these reservoirs is the type of sandstone facies. The petrophysical evaluation of both reservoirs (K and Q) depicts porosity range from fair to very good across wells (i.e 11% to 25%). From the evaluated reservoirs porosity, there is no significant reduction of porosity with depth increase. The values obtained for the permeability of both reservoirs (K and Q) varied widely and inconsistent across the wells in the study field. The various depositional environments established in BETA field include fluvial, tidal channel, mouth bars, delta front, and the reservoir sands occurring in different depositional settings, resulting from different depositional processes, which had a wide range of petrophysical properties.
