Re-entries - where an existing well is re-entered, and multiple branches drilled off the existing wellbore. New developments - where a new well is drilled with the intention of completing as a multilateral of some type. Multilateral technology can now be used as a developmental concept for an entire field and can result in significant savings.

Successful multilateral and horizontal wells require new considerations, interdisciplinary planning, and special techniques. This intense course focuses on the critical need for a …

Abstract. A steep learning curve has evolved in drilling and completing horizontal wells in the Haynesville shale. The challenge is to understand the production …

The utility model provides a brand-new radial horizontal well completing tool which regards to the problems that an existing radial horizontal well completing way is single, stability of the well wall is difficult to ensure, and a radial well hole is sandy and damaged. According to the radial horizontal well completing tool, window cutting is carried out on …

Multiple zone completion is the practice of completing a well so that hydrocarbons from two or more formations may be produced simultaneously, yet separately. For example, a well may be drilled that passes through a number of formations as it descends; alternately, it may be more effective in a horizontal well to add multiple completions to ...

Stan, I have a basic question. On LOE you estimated a $/BOE cost of $11.60/BOE and so the LOE for your example was $31,600 for a well producing 2689 BOPD. So I took the $31,600 as the daily cost ...

Similarly, horizontal wells made up about 14% of U.S. natural gas production in shale formations in 2004 and increased to 97% in 2018. Although horizontal wells have been the dominant source of production …

Blackbrush Oil & Gas began completing Austin Chalk horizontals in Karnes County, Tx., after it lost the bottom of the hole in a vertical Edwards well and looked up hole. After completing a short lateral in the chalk that made 350 barrels a day, the company began a program developing the Upper and Lower Eagle Ford intervals as well as the …

Dimmit, and LaSalle Counties. In 1990, approximately 1,000 horizontal wells were drilled worldwide and 850 of them were in the Austin Chalk formation. These first-generation horizontal wells were "open hole" wells. Rather than using the traditional method of completing a well by casing and cementing the wellbore and then perforating

Obviously, the major difference in horizontal and conventional completions is the curvature of the well bore, which can range from 1 to 2 ft for an ultra-short-radius well to 3,000 ft for a long ...

completing horizontal wells with multistage hydraulic stimulations for the construction of an enhanced geothermal system 1. Assess the applicability of oil and gas completion operations used in unconventional plays, such as multi-stage "plug and perforate" completions, to the higher temperatures, high water production flow rates, and large-

1. Field of the Invention. The present invention relates generally to horizontal well completion methods, and more particularly, to improve methods for completing the portions of a well bore and conduit which are positioned substantially horizontally in a hydrocarbon containing subterranean formation. 2. Description of the Prior Art.

Pad wells in Texas. Source: Getty Images. A new report estimates that amid strong production growth, the US shale sector is on a trajectory to drill and complete more than 20,000 wells this year. Released this month by Energent, Westwood Global Energy Group's unconventional-focused research unit, the figure represents an 8% increase …

Horizontal cased hole completions have become the accepted practice for completing wells in many shale gas plays. There has been a great deal of focus on how to optimize these completions. One of the most important, yet least discussed, concepts in horizontal shale completion optimization strategies is how to perforate to optimize for …

This course develops strategies for completing horizontal wells. It covers both cased-hole and open-hole configurations, either with or without sand control. Participants will learn the applications and dynamics of horizontal wells, including drill-in fluids, hole displacement, cementing, perforating, and stimulation.

Abstract. Because horizontal technology is being applied to more and different types of reservoirs, it's becoming apparent that better completion designs are required to optimize production rates, long-term economics, and ultimate producible reserves.In Mexico, early horizontal completions in compact sandstones reservoirs …

Selectively completed horizontal wells (SCHWs) can significantly reduce cost of completing wells and delay water breakthrough and prevent wellbore collapse in weak formations. Thus, SCHWs have been widely used in petroleum development industry. SCHWs can shorten the effective length of horizontal wells and thus have a vital effect …

Well completions should isolate the oil and gas reservoirs to protect the producing zones from non-producing zones in order to avoid interference with the producing reservoir. Well completions ...

This paper discusses coiled tubing buckling and load transmission when drilling and completing horizontal wells. Comprehensive analyses and new equations are presented to predict buckling of coiled tubing, "slack-off" weight transmission, actual bit weight or packer load, and maximum horizontal length.

The actual PI for Well C was calculated, after the completion, from FBHP and static BHP at the heel, which were derived by extrapolating the static and dynamic pressures to the open-hole horizontal section (Figure 3). Well C (Treatment B) had an actual PI of 84.28 rb/d/psi and theoretical PI of 80 rb/d/psi, indicating that Treatment B provided ...
