Directional drilling positioning calculations

Journal of Natural Gas Science and Engineering, 2020
Abstract In today's technology wells are mostly being drilled directional. Accurate positioning of the wells is required to be precisely known. During drilling the surveys of well trajectories is often calculated by one out of four calculation methodologies in use.

Directional Drilling with Casing

SPE/IADC Drilling Conference, 2003
Abstract Drilling with casing has proven to be an effective method of reducing drilling costs and solving drilling problems. Most of the current Casing Drilling* activity is focused on drilling vertical wells, but interest in directional wells is increasing as the benefits of Casing Drilling in straight holes are demonstrated.

Drilling Optimization Using New Directional Drilling Technology

SPE/IADC Middle East Drilling Technology Conference and Exhibition, 2011
Abstract A horizontal drilling campaign in Oman required an engineering solution to address the challenges in the 8.5-in. buildup section. The challenges include high dogleg requirements with dogleg severity (DLS) of 9°/100 ft to 11°/100 ft, long reactive shale intervals, poor wellbore quality, weight transfer issues, trajectory control,

Directional Measurements While Drilling

SPE Annual Technical Conference and Exhibition, 2019
Abstract Real-time downhole estimation of inclination and azimuth is desirable for improved wellbore quality, better management of the drilling process with regard to wellbore hydraulics and drilling dynamics, and is a prerequisite for advanced directional drilling services such as downhole azimuthal hold mode and surface-based automated

Deep Directional Drilling

SPE Deep Drilling and Production Symposium, 1979
Abstract The continuation of deep drilling has expanded the application for directional drilling to near commonplace proportions. Since 1968, there has been a steady progression of improvements in deep directional drilling tools and techniques.

Casing Drilling Directional Wells

Offshore Technology Conference, 2005
Abstract Over 300 commercial well intervals have been drilled with casing and retrievable BHA systems in the last five years. This activity has been focused mainly on drilling vertical wells with only about a dozen of these wells being directional.

Direct-Push Drilling

2016
Direct-push drilling technology includes methods that advance a drill by pushing, hammering, or vibrating. Although these methods do not meet the proper definition of drilling, they do achieve the same result—a borehole and, if applicable, a core. Direct-push drilling tools do not remove cuttings from the hole.

Drilling Fluid Pressure Calculation in Horizontal Directional Drilling

ICPTT 2012, 2012
Drilling fluid plays an important role in horizontal directional drilling (HDD). It cuts soil, suspends and transports cutting out of the borehole, it forms filter cake to prevent slurry lose and maintain the borehole stability. During HDD process, reasonable drilling pressure should be controlled.
