Multiwell drilling

Our tools and sensors are designed for outstanding performance under severe drilling conditions including extreme temperature, pressure, well depth, dogleg severity, drilling shock and vibrations. This combined with the collective professional experience of our team is paramount to the success of our project. Conventional reservoirs are located globally, and drilling can be onshore, on an inland barge, from an offshore shelf platform or on a deepwater floating platform, ship or semi-submersible.

But it is not as simple as merely skidding a rig over a few feet and drilling another lateral.

What is the optimum well spacing and number of wells per pad to minimize cost, maximize productivity and efficiency, and accommodate completion and production equipment? What technical and operational challenges arise when drilling multiple laterals from a common pad?

How does one mitigate the risk of Multiwell drilling collision during drilling, or production interference during completion?

What strategies are operators using to manage the complex logistics of around-the-clock operations? Are there advantages to stimulating Multiwell drilling laterals simultaneously?

What other lessons have been learned to not only reduce cost, but also improve efficiency with pad drilling? The issues may vary from one play to another, but the challenges of reducing cost, enhancing productivity and improving recovery rates remain the ultimate goals of pad drilling, regardless of the particular horizontal play.

Project Economics Ray Walker, executive vice president and chief operating officer of Range Resources Corporation, says individual well cost and performance metrics are obviously important, but overall project economics are the most critical factor in horizontal pad drilling.

Range Resources Corporation utilizes zipper fracturing on its Marcellus Shale pad locations. The crew will fracture stage one on each well of a multiwell pad, then move to stage two on each well, etc.

Range, which has about 1. It is helpful if you can amortize expenses over a larger number of wells, but you have to manage the overall economics. You have to balance the number of wells to keep whole project costs as low as possible.

The larger rig is then brought in to drill the laterals. Range uses one crew per pad, but employs zipper fracturing. For example, Walker says if there are five wells on a pad, the crew will fracture stage one on each well and then move to stage two on each well, etc.

He also notes that the first walking rig that can literally walk itself from one well to the next on the pad—now standard in the industry—was designed for Range to use in the Marcellus.

He says Range averages 6,foot laterals, compared with the industry standard of 2, feet in Walker says Range has standardized production facilities as well. It not only is cheaper, but it also is more efficient because the production equipment on every pad is prefabricated and brought to the location for assembly.

That is not a matter of efficiency, however, but a byproduct of low prices.

In this environment, you have to pay attention to every penny. It is a win-win: You are saving money and getting better production.Drilling terminology deals with major rig components, processes and equipment required to drill and case a well.
