Based on this, and the successful development of nearby areas through horizontal drilling by other operators, it was decided...

A traditional solution is to measure the apparent density and Pe of detectors at short and long-spaced detectors using a spine-and-rib plot. Subsequently, compensation is performed based on the differences in formation sensitivity of different...

The article discusses the experience of using MID-4 equipment on the multi-string wells. Based on the measurement results on physical models...

The detector counts are affected by the multilayered medium, so it is influence laws of the main control factors, such as inner and outer casing thickness, inner and outer cement...

... is calculated using Pressure Transient Analysis (PTA) from pressure buildup tests in shut-in wells. Over 20 wells with tests achieving radial flow provide the ground-truth for gas effective permeability thickness. Since PTA does not densely cover the field, we use rate transient analysis (RTA) in over 100 wells...
