inject stable foam into the hole while drilling with the button bits. The rig was equipped with amanual foam pump, which limited the potential for creating the stable foam required. Therefore,provision of a high-pressure (100 bar) foam pump, together with a 150mm button bit, would allowdrilling with compressed air and stable foam without fear of collapse of the hole. It would alsoincrease the penetration capacity of the rig at larger diameter.It was hoped that this additional capacity and facility on the rig would improve the application of therig and ensure that all potentially unstable formations can be fully cased with 110mm PVC casing.This would reduce the number of sites that have to be abandoned due to drilling difficulties.Field testing of this technique began in September 1997 and to date results have been verysuccessful, although only seven holes have been drilled so far and further testing is required.Hydraulic feed/hoist to drilling operationsThe manual operation of the hoist and light weight of rig limits the speed of drilling operations andalso the available load applied to the dragblade bit during drilling operations. Therefore, addition ofhydraulics to the rig would serve two functions:1) Provide a feed weight during drilling therefore potentially increasing the penetration potentialduring mud/dragblade drilling.2) Make drilling operations quicker and less labour intensive on the drill crew since the hydraulichoist would be used to lift the drill stem from the hole - particularly relevant on the deeper holes.New drilling rig – upgraded/up-sized Port-a-RigEureka UK Ltd, having designed two appropriate technology drilling rigs (the ‘Port-a-Rig’ and thelarger ‘drill system’), is proposing to combine elements of both rigs in the design of a newintermediate rig which will be an up-sized Port-a-Rig costing approximately £12,000. The new rigwould be fitted with hydraulics and deliver more power to drilling operations. Keyimprovements/differences to the Port-a-Rig would include:• trailer mounted rig as opposed to loading rig components onto a pick-up• hydraulic hoist/feed fitted as standard• larger drill mast, gearboxes, components etc.• 11Hp engine versus the current 5Hp engine on the Port-a-Rig.It is expected that this rig would be able to demonstrate a clear improvement in performance anddrilling capacity over the port-a-rig. It would also fit into the existing infrastructure of the project andConcern Universal. It would remain a low-cost drilling option, with drilling parameters establishedduring design but likely to be very appropriate to Malawi conditions.• Government. High personnel turnover has resulted in a change in level of co-operation atMinistry level. There is limited commitment to develop appropriate drilling technologies andresearch capacity at the Ministry is weak. Government drilling programmes are donor-fundedand cost-effectiveness is not a key issue. Possible strong lobby from commercial contractorsagainst introduction of low-cost alternatives.40
