Item 1.Security and Issuer
           This Amendment No. 9 to Schedule 13D on the Common
Stock of RPC, Inc. (the "Issuer") is being filed on behalf of the
undersigned to amend the Schedule 13D, as amended (the "Schedule
13D") which was originally filed on August 19, 1988. Unless
otherwise indicated, all capitalized terms used herein but not
defined herein shall have the same meaning as set forth in the
Schedule 13D.

Item 2.   Identity and Background
          This statement is being filed by Mario J. Gabelli ("Mr.
Gabelli") and various entities which he directly or indirectly
controls or for which he acts as chief investment officer.  These
entities, except for Lynch Corporation ("Lynch"), Spinnaker
Industries, Incorporated ("Spinnaker"), Western New Mexico
Telephone Company ("Western New Mexico"), Entoleter, Inc.
("Entoleter"),  Lynch Telecommunications Corporation ("Lynch
Telecom"), Lynch Telephone Corporation ("Lynch Telephone") and
Inter-Community Telephone Company ("Inter-Community")
(collectively, "Lynch and its affiliates"), engage in various
aspects of the securities business, primarily as investment
adviser to various institutional and individual clients, includ-
ing registered investment companies and pension plans, as
broker/dealer and as general partner of various private invest-
ment partnerships.  Certain of these entities may also make
investments for their own accounts. 
          The foregoing persons in the aggregate often own
beneficially more than 5% of a class of equity securities of a
particular issuer.  Although several of the foregoing persons are
treated as institutional investors for purposes of reporting
their beneficial ownership on the short-form Schedule 13G, the
holdings of those who do not qualify as institutional investors
may exceed the 1% threshold presented for filing on Schedule 13G
or implementation of their investment philosophy may from time to
time require action which could be viewed as not completely
passive.  In order to avoid any question as to whether their
beneficial ownership is being reported on the proper form and in
order to provide greater investment flexibility and administra-
tive uniformity, these persons have decided to file their benefi-
cial ownership reports on the more detailed Schedule 13D form
rather than on the short-form Schedule 13G and thereby to provide
more expansive disclosure than may be necessary. 
          (a), (b) and (c) - This statement is being filed by one
or more of the following persons: Gabelli Funds, Inc. ("GFI"),
GAMCO Investors, Inc. ("GAMCO"), Gabelli Securities, Inc.
("GSI"), Gabelli & Company, Inc. ("Gabelli & Company"), Gabelli
Performance Partnership L.P. ("GPP"), GLI, Inc. ("GLI"), Gabelli
Associates Fund ("Gabelli Associates"), Gabelli Associates
Limited ("GAL"), Gabelli & Company, Inc. Profit Sharing Plan (the
"Plan"), Gabelli International Limited ("GIL"), Gabelli Interna-
tional II Limited ("GIL II"), Gabelli International Gold Fund
Limited ("GIGFL"), ALCE Partners, L.P. ("ALCE"), Gabelli
Multimedia Partners, L.P. ("Multimedia Partners"), Gabelli Asset
Management Company International Advisory Services Ltd.
("GIASL"),Gabelli Foundation, Inc. ("Foundation"), Mr. Gabelli,
Lynch, Spinnaker, Western New Mexico, Entoleter, Lynch Telecom,
Lynch Telephone and Inter-Community. Those of the foregoing
persons signing this Schedule 13D are hereafter referred to as
the "Reporting Persons".
