Luke has been involved with surface, underground, navi, dewatering, directional drilling and wedging at sites all across Victoria. Luke was also a key player in the parent-daughter drilling that occurred at the Bendigo gold mine. This presentation will provide a short history of Ori tools, talk about the tools in use today and their limitations, and discuss the issues with conducting surveys in magnetic ground.

6. Drilling Fluids, the True Cost

Dave Williams, Director Keith Arnett, Sales/Technical Manager Mudex Pty Ltd Drilling fluids are designed to keep drillers out of trouble not get them out of trouble. All too often as a drilling fluids engineers we are asked to come to site to help out after there are hole problems and difficult ground conditions and develop a mud program that will allow the drilling crews to reach target depths then be told that the mud program we recommend is too expensive and can we reduce the costs. In oilfield as a rule of thumb for each well 5% of the drilling budget is allocated to drilling fluids before the rod even breaks the surface. The cost of the fluid does vary if it is Oil based, water based, highly inhibitive systems, costs go up for difficult drilling situations and problematic ground types and so on costs can go much higher easily up to 15%. Generally in non-oil field work drilling fluids cost around 1-2% of the cost of the hole, in good competent ground more meters are drilled per shift then drilling fluids cost are reduced even more. In problematic ground the cost can be as high as 10% and get to 15% where there are full losses. The issue arises that when in problematic ground it takes higher performing products to stabilize the formation. Any formation can be stabilized it just comes down to how much wants to be spent on the hole. When we look at the true cost of a drilling fluid we need to look

The performance levels (Activity Rate) Packaging Transit Mixing ability (Disperseability) Unit Price Running a pre-planned mud program prior to having difficulties Cost versus Failure (Is it worth running a cheap product if the target isn’t met?)

These things all have a major bearing on the true cost of the drilling fluids particularly running a preplanned mud program. Dave Williams founded Mudex in 2014 after several years in management roles with M-I Swaco, FluidStar, Australian Mud Company. With extensive hands-on experience in drilling and supervisory roles before gaining formal drilling fluids training in sales and technical support with a large international mud company. Dave has participated in advanced drilling fluids training courses in the United States and is based in Western Australia. Keith Arnett worked in the HDD industry for 13 years as a driller and drilling superintendent on large diameter holes throughout Australia before joining the Drilling Fluids Industry in late 2007 with FluidStar and then with AMC before joining Mudex in 2015. Keith has completed advanced drilling courses in Australia and his knowledge of the practical application of drilling fluids extends across horizontal directional drilling, mineral exploration, water boring , and civil construction. Keith is based in Adelaide, Australia

7. Drill Rig Walk-around

Luke Fitzpatrick, Supervisor Deepcore Drilling Pty Ltd Deepcore Drilling will have a drill rig on display at the CFA hard stand down the street the street from the venue. Deepcore drillers will provide a rig induction, then walk-around the rig explaining key components and answer any questions.

Session 3: New Generation Drilling Technologies

8. Coiled Tubing Drilling Rigs for Mineral Exploration

Soren Soe, Project Leader Deep Exploration Technologies CRC Coiled tubing (CT) drilling was developed for well interventions in the petroleum industry. The major advantage of CT drilling is the absence of drill rods and thus improved productivity and safety. This talk will discuss Deep Exploration Technologies Cooperative Research Centre’s (DET CRC) progress towards developing a CT rig for mineral exploration and DET CRC technologies for the conventional drilling in MINEX.

Soren Soe has held various Project, Engineering and Executive leadership positions since completing his Bachelor of Science in Engineering in 1991. He has worked extensively with leading the development of onshore drilling rigs for mineral exploration, production holes, geotechnical applications and coiled tubing rigs for the oil and gas industry. During his career Soren has expatriated to China, The Netherlands and Poland with such companies as Knebel Drilling A/S, Boart Longyear and A.P.Moller Maersk.

9. Advances in soil and groundwater sampling techniques

Mike Mercuri, Buisness Development Director Matrix Drilling This presentation focuses on recent advances in environmental and geotechnical drilling and subsequent soil and groundwater sampling techniques. Due to the importance of accurately logging soil and rock, disturbed sampling such as augering have become redundant in many cases making way for a new generation of sampling techniques. Accurate logging and keeping the integrity of samples for contaminant analysis are just a couple of reasons for the shift. The presentation will cover direct push soil sampling, sonic drilling in varying geological conditions, casing advancement as well as in-situ groundwater sampling and pre-packed monitoring piezometer installations. Mike Mercuri received his Bachelors and Honours degrees in Earth Sciences and Environmental Geochemistry from Monash University and the University of New England. He worked as an environmental officer at New England Antimony Mines prior to 10 years consulting in the contaminated land and geotechnical sector in Australia and abroad in the United Kingdom. For the past six years Mike has been owner and Business Development Director at Matrix Drilling, a professional drilling services company operating in all States and Territories in Australia.

Session 4: Post Drilling – Down hole logging and Data Acquisition

11. Measurement of water content and permeability using Downhole - Nuclear Magnetic Resonance logging instruments

Dr Tim Hopper NMR Services NMR has been used routinely in the oil and gas industry for well over 25 years as a way to characterize the fluids inside the formation. NMR is the only downhole logging tool that directly measures the water content and is not affected by the lithology in its measurement of total porosity. By virtue of some interesting physics, the NMR data is able to be separated into a clay bound water volume, a capillary bound water volume and a free water content. These can then be used to calculate a permeability / hydraulic conductivity. This talk will cover the basics of the NMR measurement and show some applications of the data in geophysics related problems. Tim has been working in the resource sector for 15 years with most of his time in the oil and gas industry. He has worked as a wireline field engineer, a NMR research scientist, an engineering project manager, a petrophysicist and he now manages his own company. He earned his PhD in Physics at QUT in Brisbane, during which he spent a year at UPenn in the USA whilst on a Fulbright Scholarship. His speciality is NMR physics and its use in formation evaluation and reservoir characterization.

12. Down-hole hyperspectral logging

Mary Harris, Project Geoscientist Rio Tinto This presentation focuses on the operational application of down-hole hyperspectral logging to the mining industry, from early exploration to resource modelling and ore processing. Hyperspectral logging of drill core has made significant advancements in the last 5 years, and now provides down-hole high resolution photography, mineralogy, mineral chemistry and crystallinity information collected in real-time, made available to clients online and can be integrated with other project data such as geochemical assays, lithology and alteration logging. Rio Tinto has recently applied this technology to porphyry Copper exploration to help define alteration zones and identify changes in mineralogy with mineralisation.

Mary began working for Rio Tinto in their Technology and Innovation group as a graduate in 2009. There she worked in diamonds exploration using Kimberlite indicator mineralogy and mineral chemistry. Mary joined Rio Tinto Exploration in 2011 in the Project Generation Group working on applying emerging technologies to operational exploration programmes in the fields of mineralogy, mineral chemistry, field spectroscopy and down-hole hyperspectral logging.

13. Maximise your exploration drilling $; capture hydrogeological data and water down your costs

Peter Smith, Consultant Hydrogeologist Drilling is expensive and we should be trying to maximise the return on the $. This presentation looks at the types of hydrogeological data that exploration and mine geologists can cheaply glean from drilling programs at the various phases of exploration and mine development. Peter has over 40 years’ experience in providing hydrogeological and geological advice to a wide range of projects in Australia and internationally both within government and as a consultant. Peter has worked throughout Australia as well Chile, Peru, India, Kazakhstan, Mongolia, Hong Kong, New Caledonia, Peru and Malaysia. He has extensive experience in: interpretation of geological, hydrogeological and geophysical data; regional groundwater resource assessment and development in sedimentary basins and fractured rock terrains; focused groundwater exploration and assessment in most hydrogeological environments including karst; investigation of groundwater dependent ecosystems and surface water / groundwater interactions; wellfield investigation and development; investigation and assessment of contaminated groundwater; development of large scale mine water supplies and pit dewatering. He was the hydrogeological representative on the South Australian government’s Water Well Drilling Committee before moving into the consulting world. Peter has been responsible for the technical and HSE input to multi-well groundwater extraction programs for mining operations, particularly in remote and arid areas.
