Stephens Co. 21-01S-04W Activity

Looks like there is no drilling going on in 21-01S-04W. They were preparing for if about a year ago but the price of oil had dropped out the bottom. Any drilling there?

Camino just pooled that section last week. The respondents have 20 days in which to answer.

The well name is listed on p 18. Gus McCrae 01S04W 16-21-1MH has a surface location in section 9, so all info is listed from 0901S04W in the OCC well records.

The well was drilled and first sales were 9/28/20. You may see a division order by February or March. 89Energy sold the well to Camino on Sept 11, 2020.

Is there a source describing fracking, horizontal drilling, and multiple horizontal wells from one vertical well? What is the sequence for putting more that 1 horizontal well in one vertical drill? Do they drill another horizontal well when the exiting one slows down?

Fracking video :Animation of Hydraulic Fracturing (fracking) - ASM International. From Marathon OIl, one of the operators in OK. Watch this first.

In general, a horizontal well is drilled almost vertically down to the kickoff point and then drilled almost horizontally into the reservoir of interest. Since some horizontals can last decades and only drain a small portion of the reservoir somewhat in the shape of a cigar that may be about 600 feet in diameter, more wells can be drilled from the same drill pad, but not from the same vertical portion. They get their own. The wells will tend to be spaced out like cigars in a box. Depending upon the number of reservoirs, they may be positioned like a wine rack. Here is a presentation from Continental Resources. file: Choose the Sprinboard update one.

Thanks M. So when they drill horizontally at one elevation they cannot well at the same elevation at a different degree of the 360 deg radius? And, even if they drill horizontally at a different elevation, they do not do that until they have extracted the majority of oil/gas at the 1st horizontal well at the previous well, right?

In Oklahoma, they generally drill in a N-S direction or S-N direction to take advantage of the fracing enhancing the natural cracks in the structural grain. They will usually have 1-3 pads on the edge of a section and then drill multiple wells from each pad. Sometimes they drill one well at the far east side or far west side and then come back in a while to drill the rest. Sometimes, they drill all four-six wells back to back. They do not want to wait too long to drill as they want to use the natural pressure to drive the well production. That first well could last 60 years, so not waiting that long to drill a second. Think of a set of six bendy straws. The vertical part of the section is one half of the straw and the other part is the horizontal. If you Google “cube development drilling strategy” Wood McKenzie has a nice diagram of a multi reservoir 3D look.

In some parts of OK, they may drill in a spoke fashion, but it is not as common.

I have several mineral interests that produce in multiple formations simultaneously. If it is feasible to explore, there is no reason to leave it in the ground. Each well provides geological data. As a well goes down through the “wedding cake” of production zones, more is learned about the potential of those zones. Some of these surface pads look like an iron orchard of “Christmas trees”.

WTI is over $55 today and trending higher.

Thanks again M. I found a couple web sites that describe the cube drilling strategy. Looks like it started about 2 years ago (if I read it correctly). So it may take a few more years to really take off on it. But if it does take off, getting the majority of oil/gas out of a good play should be a lot more efficient and faster. Let’s hope it does!
