  • Drilling Deeper
    Drilling deeper Nia Kajastie looks at the evolution of underground drilling machinery and technologies, as well as the latest equipment releases for exploration, development and production applications Nia Kajastie 19 Dec 2016 10:00 Feature Underground drilling is a vital part of exploration and hard-rock mining activities across a wide range of applications, from diamond coring, short-hole drilling for development and long-hole drilling for production, to ground support to install rock bolts or cable bolts, secondary drilling and blasting to reduce oversize, or simply utility drilling. In line with the variety of possible functions, the Figure 1A Joy DR-1SB hydraulic jumbo drill, which features Intelsense drilling control system and hydrostatic drive for a requirements of drilling equipment for lower profile and tighter turning radius exploration, development and production are dependent on a number of factors. When it comes to exploration drilling, for example, target hole depths and core size are critical to choosing the best rig and tooling. The size of the drilling stations or tunnels is also important to the selection process. According to Boart Longyear, tooling is specific to the core size required. Rods come in different lengths – so you can use 5ft (1.5m) rods if you are drilling in a confined space. Likewise, core barrels come in 5ft or 10ft lengths (1.5m and 3m). On smaller, less powerful rigs, the company recommends freer cutting bits, while also considering the geological formation. The other factor to consider when selecting the right method, rig and tooling is the angle or dip of the hole.

  • Oil Depletion and the Energy Efficiency of Oil Production

Brandt Department of Energy Resources Engineering, Green Earth Sciences 065, 367 Panama St., Stanford University, Stanford, CA 94305-2220, USA; E-Mail: [email protected]; Fax: +1-650-724-8251 Received: 10 June 2011; in revised form: 1 August 2011 / Accepted: 5 August 2011 / Published: 12 October 2011 Abstract: This study explores the impact of oil depletion on the energetic efficiency of oil extraction and refining in California. These changes are measured using energy return ratios (such as the energy return on investment, or EROI). I construct a time-varying first-order process model of energy inputs and outputs of oil extraction. The model includes factors such as oil quality, reservoir depth, enhanced recovery techniques, and water cut. This model is populated with historical data for 306 California oil fields over a 50 year period. The model focuses on the effects of resource quality decline, while technical efficiencies are modeled simply. Results indicate that the energy intensity of oil extraction in California increased significantly from 1955 to 2005. This resulted in a decline in the life-cycle EROI from ≈6.5 to ≈3.5 (measured as megajoules (MJ) delivered to final consumers per MJ primary energy invested in energy extraction, transport, and refining). Most of this decline in energy returns is due to increasing need for steam-based thermal enhanced oil recovery, with secondary effects due to conventional resource depletion (e.g., increased water cut).

Shallow deposits, along with shallow way coal and metal ores are mined. Today, however, faulting, allowed oil and gas to migrate to the surface almost all commercial oil and gas exploration is from of the land. Societies have accessed oil and gas for wells many thousands of feet deep. (Daniel Yergin, millennia.

Similarly, Moses was Free Press, New York, 1990) delivered from death in a basket coated with tar and pitch.

Department of Mechanical Engineering, Rivers State University of Science and Technology, P.M.B. 5080, Port Harcourt, Nigeria. * E-mail [email protected] ABSTRACT: One of mankind’s most important needs – water has been a very scarce commodity in Nigeria. Federal, State and Local Governments are not doing enough to provide portable water for the Nigerian populace hence borehole drilling has become a big business. Water boreholes are being drilled with manual methods using the tripod and seismic systems. These methods do not produce high quality potable water. Borehole drilling rigs that can produce appropriate quality of water are imported and are costly and borehole drillers can hardly afford them. It therefore became imperative for Nigerian Engineers to design and produce effective and cheaper water drilling rigs. Consequently, a hydraulic water drilling rig has been designed. The design satisfies the requirements of drill diameter and depth and has economic advantage over the imported rigs. The manufacture of the rig in Nigeria will also enhance the technological development of the country. KEY WORDS: Design, Portable, Hydraulic, Water, Borehole, Drilling, Rig.
