Abstract: System and method for conducting enhanced oil recovery by establishing a plurality of stacked, alternating slugs of gas and liquid travelling downhole into a subterranean well. The system can include a buffer tank including a liquid inlet through which liquid is received from a liquids source into the buffer tank, a gas inlet through which gas is received from a pressured gas source into the buffer tank, a gas outlet in fluid communication with gas reservoired in the buffer tank, and a liquid outlet in fluid communication with liquid reservoired in the buffer tank. The system can further include a pressure control configured to maintain a specified pressure in gas reservoired within the buffer tank and a fluid dispensing system in fluid communication with the gas and liquid outlets of the buffer tank.

Abstract: A surgical jig and method of use in image guided and non-guided surgery are described. The jig is for use in determining an axis of a body part. The jig includes a handle at a proximal end and a mouth at a distal end. The mouth is engagable about the body part and defines a substantially flat plane. A guide has a channel with an axis substantially perpendicular to the plane and a support attaches the guide to the jig. The guide can be translatable relative to the mouth while maintaining the axis substantially perpendicular to the plane. The method determines an axis relative to a body part using the jig. The method comprises engaging the mouth about the body part and translating the guide relative to the mouth so as to align the axis of the channel with the axis of the body part.
