... Abstract The development of a new motor designed specifically for use in holes drilled with air and mist is chronicled, from initial use of modified mud motors in air drilling applications, through development to date of an air drilling motor currently in use. Until recently, air drilling...

... Abstract Chiya Khere field development plan is to drill a lateral hole from existing pilot holes. While in the drilling phase, severe losses were hindering the drilling plans due to lack of effective solutions to sidetrack in air drilling environment. Historically, losses circulation pills were...

... Abstract This paper will present the evolution of a third-generation, point-the-bit rotary steerable system (RSS) and its successful application for air drilling of directional wells and lateral intervals. There are a number of applications for air drilling; the primary one is obviously...

... Abstract This paper details the lessons learned in late 2007 and early 2008 whilst air drilling vertical gas wells in the Travis Peak formation of the western East Texas deep Bossier play in Amoroso Field and applying the lessons learned in the US to a deep appraisal well drilled in Northern...

... Abstract Combined with actual air drilling practices and data in western China, mechanical behavior of three different BHA used in actual air drilling was investigated. Bit side force and bit tilt angle of those three BHA both in air drilling and mud drilling were calculated and compared...

... Abstract Air drilling has many advantages over mud drilling in increasing penetration rate, decreasing formation damage, eliminating lost circulation, reducing pressure differential sticking and so on. Hole cleaning and pipe erosion failure are the two key problems for air drilling. Hence...

... the corrosion inhibitor. In MPD/UBD/air drilling operations, the kinetics of passivation is important to prevent damage to the drillstring and downhole tubulars. Field Applications As previously mentioned, when designing corrosion mitigation programs for MPD/UBD/air drilling operations, one must consider...

.... This results in an increase in the operating cost and reduction of potential benefits associated with underbalanced drilling. Due to the highly compressible nature of air, the conventional power section requires modification. The primary objective of this paper is to analyze possible power section...

... Abstract Conventional methods used to steer the BHA when drilling with air are primitive and time consuming. Usually, a single shot survey tool is the most convenient option for steering the BHA. 1 Survey tools, however, are not designed for the harsh environment. Consequently...

... The Arkoma Basin, a dry natural gas producing basin in the United States, is located in northwest Arkansas and southeast Oklahoma ( Fig.1 ). The basin extends for approximately 260 miles in an east-west direction and is 20 to 50 miles wide from north to south. Air drilling is the predominant...

... Abstract By increasing penetration rates and bit life, especially in hard formation, the use of down-hole air hammers in the oil field has significantly reduceddrilling costs in the Northeast U.S. and West Texas (Ref. 1). Unfortunately, drilling by this percussion method has been limited...
