Geothermal gradients increase from east to west with relatively low values (< 0.02 K/m) in the eastern Louisiana shelf to higher and more variable values (0.03 to 0.06 K/m) in the Texas shelf. In addition, thermal gradients tend to decrease from the inner shelf (near the shoreline) to the outer shelf. Even though the Louisiana continental shelf enjoys greater oil and gas production activities than the Texas shelf, in terms of geothermal power generation, the latter looks more promising with generally higher sedimentary temperatures. In one area offshore Matagorda Island in the Texas shelf in particular, corrected BHTs exceed 150 C (302 F) at depths shallower than ~4 km (~13,100 ft) below seafloor, and it may be worth serious consideration for geothermal power generation. In many other areas in the westernmost Louisiana through Texas shelf, sediment temperatures are measured or estimated to be over 160 C (320 F) at 5-km (16,400-ft) depth based on the trends of the BHTs obtained at shallower depths.  2WX   ( 6 9 \ h n B F K T k ' V [ a g {    Q ` 麴噤茕劁卦匦漯嗵鹑鹑鹑嗄嗬嗬嗄棠心继懈碳天碳碳淘谈谈谈旒旄几hP]h mh鮁h齫hzreh4>kh+-hR shh:h(h嘋h榲0hMh罞hh"h褿-GXYj;;` e :;麴豇h"h醗zhFhMhZK 21恏:p _靶/ 班=!盃"盃#悹$悹%靶靶 愋@@@ NormalCJ_HaJmH sH tH DAD Default Paragraph FontRiR  Table Normal4 l4a (k(No List;  XYj=0€€0€€0€€0€€0€€0€€` ; ; ; /,腷/tlb/敮b/4(b/c/,Yc/躧b/l腷/煲D/D/t渂/|v/淞b/\c/烀b/ /// /鋁c|pzy=     y€= =*€urn:schemas-microsoft-com:office:smarttags €PlaceName€=*€urn:schemas-microsoft-com:office:smarttags €PlaceType€>*€urn:schemas-microsoft-com:office:smarttags €PostalCode€9*€urn:schemas-microsoft-com:office:smarttags€State€9*€urn:schemas-microsoft-com:office:smarttags€place€8*€urn:schemas-microsoft-com:office:smarttags€City€ 8==36BFKT'V[ajoz{  33RV`e:==0u 奷Y?U0  * 襬 禗錨翽:嘋4OY辮9"74#虴$監%e%€,'3(騖)=,+-褿--嶧0榲0)X1C#5x66,7=::<%<踸<:J=詅>0@ADzD EG H6I(*N觵N=P W扝W\hX_ _`ZB` bzreavfgSVg>j4>k m鳳o8TpR s7shswyXx醗z=K{諰|FY}鮵€!/蜹GV"鞿,x攙2M竐ZK鮃鮁P]噓c >Lw 2u賆 (DT齫0D58b.騜趠OeR?C;璅鞧z'F 75vg頚<3舓╣iu 鮹,罞Gm8Z峓).bwDFN3 ''/蚒3\D DISb ~@€::繰--::;@UnknownG噝 €Times New Roman5€Symbol3& 噝 €Arial"q鹦hCr&qz礔M M $x倐24d882IX)?"2WTemperature Distribution within Deep Sediments of the Texas-Louisiana Continental ShelfSeiichi NagiharaSeiichi Nagihara鄥燆鵒h珣+'迟0 ,8L ht   XTemperature Distribution within Deep Sediments of the Texas-Louisiana Continental ShelfSeiichi Nagihara Normal.dotSeiichi Nagihara16Microsoft Office Word@晶@B〝0柷@(,椙M胀諟.摋+,0T hp  4Texas Tech University 8 XTemperature Distribution within Deep Sediments of the Texas-Louisiana Continental Shelf Title  !"#$%&)Root Entry F怈;椙+€1Table SWordDocument4SummaryInformation(DocumentSummaryInformation8CompObjq  FMicrosoft Office Word Document MSWordDocWord.Document.89瞦Root Entry F傲椙1€1Table SWordDocument4SummaryInformation( 0/ Title4 $€, DocumentSummaryInformation8CompObjq  FMicrosoft Office Word Document MSWordDocWord.Document.89瞦胀諟.摋+,D胀諟.摋+,T hp  4Texas Tech University 8 XTemperature Distribution within Deep Sediments of the Texas-Louisiana Continental Shelf
