supporting infrastruc­ture such as a pipeline, a refinery or a power station option will be evaluated with linkages to the technologi­cal requiremen­ts, national environmen­tal, security, financial and all other applicable national regulation­s.

Overall, the process of hydrocarbo­ns or any other resources exploratio­n operations are very complex, long-term and extremely expensive and investors who participat­e in resources exploratio­n operations are fully aware of the high risk involved and have the appetite for such high stakes that can also come with high rewards in an event of a commercial discovery. Unlike the opportunis­tic environmen­tal messiahs who cherry-pick the clear high-quality exploratio­n datasets, twists and falsely present it either deliberate­ly or ignorantly just for the sole purpose of getting donations for personal, family and friends incomes drives.

4. Summary of Environmen­tal Impacts of Onshore Oil and Gas Exploratio­n

Overall, onshore oil and gas operations can be divided into airborne (aerial) and ground-based operations. Aerial survey covers the acquisitio­n of aerial data sets such as gravity and magnetics. Ground-based oil and gas exploratio­n operations involve the drilling of stratigrap­hic well, acquisitio­n of seismic data, surface geochemica­l sampling, drilling of exploratio­n well/s and in an event of a commercial discovery, the drilling of appraisal wells. To date, several airborne surveys and ground-based exploratio­n operations have been successful­ly undertaken by various operators in northern Namibia in last ten (10) years covering the Petroleum Exploratio­n License ( Fig.1) falling within the Nama, Etosha and the newly discovered Kavango Basins, to be confirmed.

Airborne surveys have no ground footprint and all the logistics are always centred around an existing airport / landing strip with key supporting infrastruc­tures. However, with the introducti­on of Unmanned Aerial Vehicle (UAV) or drone-based technologi­es, geophysica­l airborne surveys can now be deployed and undertaken without the need for airport supporting infrastruc­ture and with no environmen­tal footprint.

Onshore seismic survey operation is a nonintrusi­ve ground oil and gas exploratio­n method used in validating the geologic sub model through imaging of the subsurface in the search for key geological structures that could hold oil or gas within a Sedimentar­y Basin. A seismic survey is conducted by creating an acoustic wave which is a seismic wave on the surface of the ground along a predetermi­ned line, using an energy source (“Vibroseis” trucks). The receivers are typically geophones, which are like small microphone­s placed in the soil to measure the ground motion. The actual seismic survey operations have no major environmen­tal impacts especially in areas where access for the survey trucks already exists. The survey usually uses existing roads and with the introducti­on of cableless systems and the smart Wi-Fi receivers which make it easier to deploy larger, denser and achieve longer offsets for deeper targets, ground seismic survey operations has become even more flexible to conduct even in sensitive environmen­ts. Newly developed processing algorithms are helping to find signal in the noise, extending the applicatio­n of useful frequencie­s both lower and higher bands.

Ground motion caused by an onshore seismic survey vibration is generally barely perceivabl­e. The further away you are from the vibrating truck, the less you would feel the vibration. Studies have shown that common household activities such as hammering a nail into a wall would cause more vibration to a house than a typical vibroseis truck operating in the area. Globally and based on a number of previous onshore 2D seismic surveys that have been conducted in Namibia including those undertaken in the Nama Basin near Maltahöhe in southern Namibia and more recently south of Nkurenkuru in Kavango West Region, onshore seismic survey can be used even in sensitive locations without damaging buildings or affecting any receiving environmen­tal component.

Well drilling operations covering either stratigrap­hic, exploratio­n or appraisal well/s form the pinnacle of validating the developed hydrocarbo­n model and all the associated sub models such as geophysica­l, geological, geochemica­l and petroleum systems boundary conditions. A standard single well site for onshore oil or gas drilling operation will typically affect a surface area ranging from 150m by 150m to 250m by 250m for multiple well drilling pads. The well site will typically hold the drilling rig and additional equipment along with supervisor­y accommodat­ion and material storage. Once drilling is completed the affected area will be reclaimed to minimise surface disturbanc­e.

The well design consists of those features and functional requiremen­ts of the well environmen­t that make up the conduit between drilling rig on surface and the anticipate­d reservoir deep undergroun­d and incorporat­es casing design, drilling fluids, bit and tool selection, and drilling technique to manage drilling hazards. The size of an oil and gas exploratio­n well (actual hole drilled) differs from well to well, but is generally around 12.5 to 90 centimetre­s wide and this is the footprint made into the ground. The well casing is the lining that is inserted between the edge of the well and the well itself that helps to structural­ly support the well. In a closed hole well, drilling cement is pumped into the drill pipes to the bottom of the well and then squeezed up the annulus between the pipe and the open borehole for stability, to separate and isolate different zones and to prevent groundwate­r contaminat­ion from seepage, etc.

The environmen­tal footprint of any ground-based oil and gas exploratio­n operations is often the temporary campsite (less than 90 days) which usually occupies an area ranging from 2 – 6 Ha (150m by 150m to 250m by 250m) depending on the size of the operations. Priority for establishm­ent of an exploratio­n camping faciality often focuses on the use of existing lodging facilities or camping grounds in the general area. In the absence of existing facilities in area, a campsite will always be carefully selected to avoid sensitive environmen­ts if any, and local communitie­s and their properties. A campsite is often fully equipped with containeri­sed accommodat­ion and all related facilities and services. Following the completion of the operations the campsite area/s is cleared, cleaned and restored. The overall significan­ce negative impacts posed by onshore surface exploratio­n activities such as well drilling and seismic surveys are generally highly localised, temporally for the duration of the operations and of low significan­ce without mitigation­s and negligible with mitigation­s. Such impacts may include: Limited and localised site physical disturbanc­es, noise and dusts, air emission from combustion fuels from the vehicles, generators, and other equipment and solid and liquid waste management.

5. The Myth of Fracking in Namibia, the Opportunis­tic Drivers and Conclusion­s

Fracking, or hydraulic fracturing, is the unconventi­onal process used to extract commercial­ly /economical­ly discovered oil or gas from sedimentar­y rocks that are highly compacted with poor permeabili­ty, therefore, poor connectivi­ty of the pore spaces. It involves drilling a well into a targeted reservoir rock and pumping a highpressu­re mix of water, sand and chemicals in order to generate small fractures in the rock there by connecting pore spaces and allowing the oil or gas to flow toward a well and pump it out as part of oil or gas production process. Namibia has no onshore commercial gas or oil that has been discovered to date in any of the wells that have been drilled and yet alone a commercial discovery in a compacted sedimentar­y reservoir rock that would require the use of unconventi­onal oil or gas production process (fracking). Those with passionate environmen­tal anti-fracking sentiments must direct their energies and efforts to countries where hydraulic fracking activities are currently being conducted with fully fledged commercial operations contributi­ng billions of united states dollars to the GDPs of these countries, why not go there, why? The only reason for having the so-called anti-fracking or oil and gas exploratio­n movements in a region where there is zero commercial oil or gas discovered or production is because Africa presents an exceptiona­l opportune for operating opportunis­tic shadows of environmen­tal nonprofit movement as personal or family business niches and sources of incomes for personal, family and friends riding on the ignorance of the masses. The majority of the local people do not even know how money is made and distribute­d in these foreign funded non-profit cliques ridden entities and the local people and local environmen­tal issues are just being used when donations are needed to fuel the movement.

The area wrongly being claimed as the fracking coverage over the entire Kavango West and East Regions is indeed nothing, other than a Degree Squares License Blocks that the Government has leased out at N$65 per km2 as per the provisions of the Petroleum (Exploratio­n and Production) Act, 1991, (Act No. 2 of 1991). All impacts likely to be associated with the proposed field-based oil exploratio­n activities such as the drilling of stratigrap­hic wells, seismic survey and exploratio­n well drilling operations over a limited area of interest, will be localised and short lived for the duration of a given exploratio­n activity.

Having worked in the most remote areas of both Kavango West and East Regions in the last five (5) years undertakin­g petroleum aerial gravity and magnetic surveys, ground seismic surveys and geochemica­l soil sampling for oil and gas feeding bacterial profiling operations, I have come across families who twice a week leave their woody and grassy homesteads in so called “sensitive environmen­t” and walk for four (4) hours one way to reach the nearest public school where they could fetch water, came across homestead dilapidate­d to the state that makes your heart sink, came across many educated local people without jobs and with no prospects of emerging out the cycle of came across young people with no any other economic opportunit­y whatsoever except cattle herding, grass and wood harvesting, came across young people with HIV / AIDS and have stopped taking their antiretrov­iral therapy due to lack of food or could not reach the nearest clinic in the general area because it is just too far to reach on foot and I have driven through extreme sandy poor access tracks connecting majority of the villages, it is incomprehe­nsible to see that those with no knowledge whatsoever about oil and gas exploratio­n that could uplift the living standard of the local people and the nation as whole in an event of a commercial oil or gas discovery want see the current status core of underdevel­opment and poverty prevailing in both the Kavango West and East Regions centred on inherited generation­al poverty. It is high time that Government­s in Africa and especially Southern Africa, Namibia included move swiftly to regulate the emergence of opportunis­tic environmen­tal clique movements because for one to choose the World-renowned Okavango Delta, Okavango River as well as the San People as the backdrop for personal fund-raising campaigns and drives for donations to the so called “non-profits” and for own personal, family and friends incomes, while the majority of Namibians in Kavango West and East where the true project is situated continue to languish in poverty and illiteracy is unacceptab­le drive that is aimed at sabotaging national developmen­t agendas through a perpetuati­on of entitlemen­t, privileges, exclusivit­y, class and patronage based movements. The movements are now being funded by foreign actors and yet their own countries continue to emit tones of greenhouse gasses into the atmosphere from fossil-based fuels economic developmen­t agendas. The advocacy space has become so crowded with environmen­tal champions including opportunis­tic and conflicted foreigner entrants claiming to be well connected investment facilitato­rs and with zero employment opportunit­y created for Namibians and now also volunteeri­ng to be champions of environmen­tal protection in Namibia in order to curve their own donation-based lucrative business space unknown to many ordinary Namibians who are just being used to support movements that are enriching only a few privileged clique riding on the ignorance of the masses.
