Determination of optimal air flow rate in air drilling

Journal of Petroleum Science and Engineering, 1992
Abstract Optimal design of any drilling program requires good knowledge of wellbore hydraulics. Established techniques are available for formulating some understanding of the associated wellbore hydraulics for conventional mud drilling, but this is not the case for air drilling.

Compositional Logging of Air-Drilled Wells

AAPG Bulletin, 1961
ABSTRACT The mineralogical compositions of representative samples of air-drilled cuttings taken at 10-foot intervals from two wells in the Punxsutawney-Driftwood gas field of central Pennsylvania have been determined by routine methods of X-ray analysis. Distinct mineralogical zones were found to correspond closely with formations and

Simplified Approach to Air Drilling Operations

Proceedings of SPE Eastern Regional Meeting, 1984
Abstract Traditionally, air requirements during an air drilling operation involve the utilization of the Angel's chart(s). The values from the mentioned chart(s) are generally 20-25% below the acutal field's requirements/needs. Recent studies in this area have provided more reliable results, however, the tedious calculations, the lack of

Modifications To and Experience With Air-Percussion Drilling

SPE Drilling Engineering, 1989
Summary Shell Canada Ltd. has air-percussion drilled 48 wells since Fall 1983. The industrial hammer was used predominantly, but the older oilfield hammer was used occasionally. A total of 117 solid-head bits were run. Experiences with the industrial percussion hammer indicated that tool modifications were required to reduce hole ...

A Closed Circulating System for Air Drilling

Proceedings of IADC/SPE Drilling Conference, 1998
Abstract Current practice while air or air/mist drilling in the Arkoma Basin is to exhaust all fluids and cuttings into an earthen waste pit. A system has been developed to eliminate the waste pit without otherwise changing the basic drilling process and conditions.

Volume Requirements for Air or Gas Drilling

Transactions of the AIME, 1957
Published in Petroleum Transactions, AIME, Vol. 210, 1957, pages 325–330. Abstract Drilling rate is a parameter that should be considered in determining the volume requirements for air and gas drilling.

Field Results of Percussion Air Drilling

Journal of Petroleum Technology, 1965
Abstract Pneumatic down-hole percussion tools have drilled many feet of hole under diverse conditions in varied formations. The analysis of the field records describes the tool's performance under general field operating conditions.
