• . Page 2 of 6 <br /> Well 5-Ap.15 -Ap17, <br /> SB4 -Ap 18 - 23 <br /> PDW's - It's hard to say the schedule, but I'm thinking 4 days each, depending on how smooth it <br /> goes. Tentatively scheduled to be done with onsite drilling mid-late May. <br /> About the exploratory mud borings, that's a great idea. I was talking to Frank about it and the <br /> only problem with it is that we HAVE to have soil samples every 5 feet and that's really difficult on <br /> a mud rig. Let's talk about it when you're out in the field setting Well 5 (probably Thursday), <br /> maybe we can come up with something. <br /> I assume we are OK to go tomorrow? Everybody is scheduled to start in the morning, so if the <br /> permit is going to take a few more days, let me know so I can call everybody involved. <br /> Thanks, see you Thursday, <br /> Dennis <br /> From: Mike Infurna [EH] [mailto:MInfurna@sjcehd.com] <br /> Sent: Monday,April 14, 2008 9:14 AM <br /> To: Dennis Leikam <br /> Subject: RE: MW work plan <br /> THat would be my first guess..Maybe just a Monday am thing. <br /> at any rate, I'm going thru your last submittal, your March 21 letter to me. <br /> I understand the original 8 well install is down to 6 in this phase. Right? <br /> What I'm NOT clear on is: <br /> 1-which well is proposed to be inside the conductor casing (cc). <br /> 2- I'll need to see 'centralizers'on the conductor casing, at least at the bottom. THe grout annulus MUST <br /> be NLT than 2-inches. Placing a steel casing of a potentially long length into a large hole without <br /> centralizers can allow the cc to rest against the wall. THis is not allowed. I've spoken to Frank at V&W <br /> and he understands I will require at least the BOTTOM of the cc to have centralilzers. I figure if we start <br /> centralized at the bottom, all we have to do is centralize the cc at the top and if the welds are straight then <br /> the grout annulus can be maintained. <br /> 3- drill dates and schedule of field work. <br /> I was wondering about using an Exploratory boring/e-log/gamma log. Have you thought of this? We know <br /> drilling out there is a turkey shoot at times and mostly hard with HSA. Since we're/you are NOT sure of the <br /> target depth, how do you feel about a MUD ROTARY small diameter exploratory hole that elogs the soils? <br /> sensitive to saline too. A gamma scan would help with the clays..Once you determine your depths of <br /> concern, we can continue to ream out the hole with MUD rotary and set the cc. <br /> From: Dennis Leikam [mailto:dennisl@olives.com] <br /> Sent: Monday, April 14, 2008 8:49 AM <br /> To: Mike Infurna [EH] <br /> Subject: RE: MW work plan <br /> Hi Mike, <br /> I got a message that you called, I guess we're having problems with our voice mail <br /> system. If you need to chat, you can reach me on my cell phone 321-2079 or shoot me an <br /> email. I'll try to give you another call in a bit if I don't hear from you. <br /> 5/7/2008 <br />
