Total improves well service method to maintain performance

As a move to maintain production performance of its aging wells, Total E&P Indonesie has decided to use ClearPac fluids provided by oil and gas service company Schlumberger Ltd on its future gravel pack operations in its Mahakam Block, East Kalimantan.

?The technology was used for the first time after laboratory tests qualified the fluid as a replacement for the HEC-based fluids used previously,? said Schlumberger in a statement.

?After clean-up, the first field test on a well in the field produced at double the rate expected using the previous technology. Based on these results, TEPI has decided to use ClearPAC fluids on future gravel pack operations in East Kalimantan,? the company said.

Gravel pack is a sand control method used in wells to prevent the production of formation sand into the well-bore. The objective of gravel pack is to stabilize the formation while causing minimal impairment to well production.

In gravel pack operations, a stainless steel screen is placed in the well-bore and the surrounding annulus is packed with prepared gravel of a specific size. The gravel pack is designed to prevent the passage of formation sand.

Total E&P Indonesie is the operator of the Mahakam block, the key gas supply to the Bontang LNG plant.
