Abstract
Abstract Communication with a measuring-while-drilling equipment sub, when the sub is at the surface, is established by placing a transmitter-receiver within transmitting range of the electrode/antenna array of the sub. The transmitter-receiver must be compatible with the sub equipment and be capable of transmitting to the sub instructions to dump the sub memory and/or add data to the sub memory.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
207 words
A method for communicating between surface equipment and a downhole measurement-while-drilling assembly when said assembly is at the surface, wherein said assembly includes at least one sensing means for measuring a downhole parameter, a downhole transmitter, a downhole receiver and information storage means, said downhole transmitter and said downhole receiver being connected between said sensing means and said information storage means, said sensing means operable in both a normal sensing mode and in a communication mode, and wherein said surface equipment includes communicating means, a surface transmitter, a surface receiver and data acquisition means, said surface transmitter and said surface receiver connected between said data acquisition means and said communicating means, comprising the steps of: placing within communicating range of said downhole sensing means compatible communicating means of said surface equipment; and communicating directly between said surface equipment and said downhole assembly by communicating from said data acquisition means of said surface equipment through said surface transmitter and said communicating means to said information storage means through said downhole equipment sensing means and said downhole receiver or from said information storage means through said downhole transmitter and said downhole equipment sensing means to said data acquisition means through said surface equipment communicating means and said surface receiver.
Claim 2
Independent Claim
207 words
A method for communicating between surface equipment and a downhole measurement-while-drilling assembly when said assembly is at the surface, wherein said assembly includes at least one sensing means for measuring a downhole parameter, a downhole transmitter, a downhole receiver and information storage means, said downhole transmitter and said downhole receiver being connected between said sensing means and said information storage means, said sensing means operable in both a normal sensing mode and in a communication mode, and wherein said surface equipment includes communicating means, a surface transmitter, a surface receiver and data acquisition means, said surface transmitter and said surface receiver connected between said data acquisition means and said communicating means, comprising the steps of: placing within communicating range of said downhole sensing means compatible communicating means of said surface equipment; and communicating directly between said surface equipment and said downhole assembly by communicating from said data acquisition means of said surface equipment through said surface transmitter and said communicating means to said information storage means through said downhole equipment sensing means and said downhole receiver or from said information storage means through said downhole transmitter and said downhole equipment sensing means to said data acquisition means through said surface equipment communicating means and said surface receiver.
Claim 3
Dependent Claim
36 words
A method according to claim 1 further comprising the step of: transmitting from said surface equipment to said downhole equipment instructions for the information storage means to transmit data contained therein to said data acquisition means.
Claim 4
Dependent Claim
47 words
A method according to claim 1 further comprising the step of: transmitting from said surface equipment to said downhole equipment instructions to be stored in said information storage means pertaining to further sensing to be performed by said at least one sensing means in a downhole environment.
Claim 5
Dependent Claim
31 words
A method according to claim 1 wherein said sensing and communicating means are electrodes and said step of bringing said sensing and communicating means within communicating range comprises making electrical contact.
Claim 6
Dependent Claim
14 words
A method according to claim 1 wherein said sensing and communicating means are antennas.
Claim 7
Dependent Claim
18 words
A method according to claim 1 wherein said downhole transmitter and said downhole receiver operate using sonic waves.
Claim 8
Dependent Claim
18 words
A method according to claim 1 wherein said downhole transmitter and said downhole receiver operate using electromagnetic waves.
Claim 9
Dependent Claim
16 words
A method according to claim 1 wherein said downhole measurement-while-drilling assembly remains closed during said communicating.
