Patent number: 9033064Abstract: A method of monitoring a well for unwanted formation fluid influx is disclosed. Measurements of well outflow are acquired during a period in which drilling operations are performed for the well. Occurrences of stagnant flow events during the period are determined. An outflow signature is generated from the well outflow measurements for each stagnant flow event. The outflow signatures are displayed sequentially in time of occurrence. Each outflow signature is analyzed for an anomaly.Type: GrantFiled: November 30, 2012Date of Patent: May 19, 2015Assignee: NATIONAL OILWELL, VARCO, L.P.Inventor: William Leo Koederitz

Patent number: 9027671Abstract: Apparatus and method for automated drilling of a borehole in a subsurface formation. In one embodiment, a method includes selecting at least one control variable. A drilling performance objective having a value that is influenced by drilling of the borehole using the at least one control variable is defined. A first interval of the borehole is drilled maintaining the at least one control variable at a first value. A second interval of the borehole is drilled maintaining the at least one control variable at a second value. A third interval of the borehole is drilled maintaining the at least one control variable at a third value. The third value is selected based on a comparison of the values of the drilling performance objective while drilling the first interval and second interval to a predetermined optimal value of the drilling performance objective.Type: GrantFiled: November 4, 2011Date of Patent: May 12, 2015Assignee: National Oilwell Varco, L.P.Inventor: William Leo Koederitz

Patent number: 8746459Abstract: Methods for automatically controlling a vibratory separator, e.g., but not limited to a shale shaker for processing drilling fluid, the methods in certain aspects including: introducing material to a vibratory separator; sensing with sensor apparatus a state parameter indicative of operation of the vibratory separator; providing a signal indicative of a value of said state parameter to control apparatus; and, with the control apparatus, automatically controlling the vibratory separator based on the level of the state parameter. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 CFR 1.72(b).Type: GrantFiled: June 10, 2009Date of Patent: June 10, 2014Assignee: National Oilwell Varco, L.P.Inventors: Eric Landon Scott, George Edward Smith, Lyndon Ray Stone, Norman Frank Padalino, Kevin Thomas McDonough, Kenneth Wayne Seyffert, William Leo Koederitz, Mallapa Ishwarappa Guggari, Guy Lamonte McClung, III

Patent number: 8590635Abstract: A method for automated drilling of a borehole in a subsurface formation includes drilling the borehole using a set of drilling control variables assigned a set of values. An automated drilling index of the drilling is monitored. The automated drilling index of the drilling is a combination of a first index that depends on a rate of penetration of the drilling and a second index that depends on a mechanical specific energy of the drilling. The values assigned to the set of drilling control variables are selectively adjusted at least once during the drilling based on the monitoring of the automated drilling index.Type: GrantFiled: December 7, 2010Date of Patent: November 26, 2013Assignee: National Oilwell Varco, L.P.Inventor: William Leo Koederitz
