摘要:
A system and method for improving drilling efficiency using drilling efficiency reference from a previously drilled offset well. In one embodiment a method for drilling a borehole includes displaying a graphical representation of drilling efficiency for a previously drilled wellbore. A graphical representation of drilling efficiency for the borehole is also displayed. The displayed drilling efficiency for the previously drilled wellbore is compared to the displayed drilling efficiency for the borehole. Responsive to the comparing, the drilling efficiency for the borehole is adjusted by changing a parameter affecting the drilling of the borehole.
摘要:
A method for facilitating a wellbore operation with a wellbore apparatus (10) , the method comprising the steps of acquiring data with sensor apparatus at at least two points along said wellbore apparatus, the method further comprising the step of using the acquired data to calculate a mechanical specific energy value for each of said at least two points along said wellbore apparatus and monitoring said mechanical specific energy values.
摘要:
A method for monitoring the health of a choke used in wellbore operations, characterised in that the method comprises the steps of isolating the choke from an operative state, activating the choke and monitoring the choke during activation to assess the health of the choke.

摘要:
A vibratory separator (120) for screening solids laden drilling mud, said vibratory separator comprising at least one screen (121, 122, 123) arranged in a basket (101) isolated from a base (105), vibratory apparatus (107) for vibrating said at least one screen and means (131, 132, 133) for adjusting the angle of said at least one screen, such that in use solids laden drilling mud forms a pool on said at least one screen, the pool having a surface (137, 138, 139), the surface having a trailing edge defining a beach characterized in that a measuring device (124, 125, 126) is arranged to measure a distance related to the position of the surface to assess the length of said beach.

摘要:
A method for setting down a bit in the construction of a well, the method comprising the steps of establishing a setpoint for weight-on-bit; monitoring actual weight-on-bit; and increasing actual weight-on-bit in a gradual manner until the setpoint is reached.
