    New CBM field test.

    zdaso4, The HQ coring system allows for continuous coring with the cores being wireline retrievable. We will have the cannisters and testing trailer onsite and the core will go into the cannisters as they are removed from the core sleeve. I had not thought ahead far enough to run a...

    New CBM field test.

    Hey zdas04 and anyone else who has a thought on the subject. I am preparing to drill some coal exploration holes that are going to be permitted as gas wells just in case the gas content warrants a pilot project. This is a new field test a couple of hundred miles from the nearest CBM...

    Well Kill Operations

    reiszal, I took the liberty of posting your question here: http://drillingclub.proboards16.com/index.cgi?board=wellcontrol&action=display&num=1076686457 Hopefully someone there will be able to answer your question to your satisfaction. Cliff

    Fluid Level Calculation in CBM Wells

    Mr. Simpson, Wow! What an information laden post. Thank you. I must agree that CBM is a whole new world everyday and the challenges tickle the brain. Now if we could get people to look at some oil fields with the "open to new procedures" approach that CBM dictates (like that will...

    Heavy Oil Economics

    PatMcG, I do not do economic forecasts on a regular basis nor do I have the "credentials" to do them. I have had to try and make forecasts on "hard to forecast" projects before. My suggestion would be to base the prediction on past performance of a group of similar or near...

    Fluid Level Calculation in CBM Wells

    Zdas04, Now, don't take me wrong here. I am not trying to tick you off. When I don't understand how a theory can be correct I have to challenge it. I'm not challenging your results. You were there I wasn't. I don't buy the interpretation of how the results were achieved. If I knew how to...

    Fluid Level Calculation in CBM Wells

    grcontrol, I have to disagree to some extent. The principal problem in CBM is to convince the company to spend the money to drill a sufficient amount of rathole to enable the pump to be set +/-75' feet below the perforations and still have rathole for solids to collect in. The benefits of...

    Fluid Level Calculation in CBM Wells

    grcontrol, You may be able to estimate it that way if the well is not flowing. Once you start moving gas all bets are off. As Mr. Simpson says, "froth". About the best you can do is base it on experience with wells in the area and even then it's a guess. I know of a well that will...

    minimum rate to partially kill gas well

    Lidge, I don't know a rule of thumb but I can tell you from experience that the rate you have will be sufficient. Yes, it will take longer and a larger volume of fluid to evacuate the gas from the tubing but you will be successful. Simply overdisplace to compensate for the lower rate. Out of...

    Insulating API Tank Roof

    Hazop, I work in an area in which the oil has a a high pour point due to wax. The oil is consistently kept @ 180 degrees F. The spray on foams are used by some operators and are painted with a rubberlike paint. Some operators use a foam sheet covered with chicken wire and coated with tar...

    Crude Buyer rejecting oil

    I'm having a problem with crude oil being rejected by the refinery's buyer. The oil is around a 44 gravity @ 180 degrees. It is a high paraffin content oil. The problem is that during the grind out what appears to be asphaltenes (at least to me) is settling out above the water and below...

    Any experience and knowledge on Hydraulic Lift?

    Rusman, Are you referring to a hydraulic artificial lift system which uses hydraulic power (either water or oil under pressure) to operate a downhole reciprocating or jet pump? Or have you heard of something else? What situation are you wanting to use it in? Cliff

    Well testing

    wlka, There are so many different ways to test wells and the "best" way is to tailor it to fit the individual well coditions. I agree with 74Elsinore, we could use more details on the well and its production types, even the area it is in. kahalikk, A 2 phase separator separates...
